Abstract
Anemia remains one of the most pervasive nutritional deficiencies affecting young women globally, with female students representing a particularly vulnerable demographic due to the convergence of physiological, dietary, behavioral, and socioeconomic factors. This review synthesizes current epidemiological evidence, pathophysiological mechanisms, and intervention strategies relevant to anemia in female student populations across diverse geographical and institutional settings. Drawing upon recent population-based surveys, cross-sectional studies, and systematic reviews published between 2020 and 2025, this article examines the multifactorial etiology of iron deficiency anemia among university and college-enrolled women, with particular attention to menstrual blood loss, dietary inadequacy, psychosocial stressors, and academic performance outcomes. The analysis reveals that anemia prevalence among female students ranges from approximately 15% in high-resource settings to over 60% in low- and middle-income countries, with substantial variation attributable to local dietary patterns, healthcare access, and sociocultural norms surrounding menstruation and nutrition. The review further evaluates the effectiveness of screening programs, iron supplementation protocols, dietary modification strategies, and campus-based health interventions, identifying evidence-based recommendations for institutional policy and clinical practice. The findings underscore the urgent need for integrated, gender-sensitive approaches to anemia prevention and management within educational settings, emphasizing that addressing this condition is not merely a matter of individual health but a critical determinant of educational equity, economic productivity, and long-term public health outcomes.

1. Introduction
The transition from adolescence to young adulthood represents a pivotal developmental window during which nutritional status exerts profound and lasting influences on physical health, cognitive function, and psychosocial wellbeing. For young women enrolled in higher education institutions, this period is characterized by unique physiological demands—most notably, the establishment and maintenance of regular menstrual cycling alongside continued somatic growth and development—that render them disproportionately susceptible to iron deficiency and its clinical manifestation, anemia. The intersection of biological vulnerability with the lifestyle transitions inherent to university life, including altered dietary habits, increased academic stress, irregular sleep patterns, and limited healthcare engagement, creates a perfect storm of risk factors that elevates anemia prevalence well above that observed in the general female population.
Anemia, defined by the World Health Organization as a hemoglobin concentration below 12.0 g/dL in non-pregnant women, affects an estimated 1.92 billion people worldwide, with women of reproductive age bearing a disproportionate burden of the disease. Among this demographic, female students constitute a particularly concerning subgroup, not merely because of their elevated risk of developing iron deficiency, but because the consequences of untreated anemia extend far beyond physical symptoms to encompass diminished academic performance, impaired cognitive function, reduced physical capacity, and compromised mental health. The insidious nature of iron deficiency anemia—its gradual onset, nonspecific symptomatology, and frequent normalization of fatigue and weakness as inevitable features of student life—contributes to substantial underdiagnosis and undertreatment, perpetuating a cycle of preventable morbidity that undermines both individual potential and institutional educational outcomes.
The global landscape of anemia among female students reflects stark disparities shaped by geography, socioeconomic status, and healthcare infrastructure. In high-income countries, where dietary diversity and food fortification programs have reduced overall anemia prevalence, female students nonetheless remain at elevated risk due to restrictive eating patterns, vegetarian and vegan dietary choices, heavy menstrual bleeding, and the psychological pressures of academic life. In low- and middle-income countries, the burden is compounded by food insecurity, limited access to iron-rich foods, high rates of parasitic infection, and inadequate menstrual hygiene management, with prevalence rates frequently exceeding 50% among female university populations. These disparities are not merely statistical artifacts; they represent tangible differences in life chances, educational attainment, and future economic participation that demand targeted, context-appropriate public health responses.
The recognition of anemia as a modifiable risk factor for poor academic outcomes has prompted growing interest in campus-based screening and intervention programs. However, the evidence base for such initiatives remains fragmented, with considerable heterogeneity in study design, intervention components, and outcome measures limiting the generalizability of findings. Moreover, the traditional biomedical model of anemia as a purely nutritional deficiency has increasingly given way to more nuanced understandings that acknowledge the role of inflammation, hormonal regulation, genetic factors, and social determinants of health in shaping individual risk profiles. This evolving conceptual framework has important implications for how anemia is identified, prevented, and managed within educational settings, necessitating approaches that extend beyond simple iron supplementation to encompass comprehensive dietary counseling, menstrual health education, mental health support, and structural interventions addressing food insecurity and healthcare access.
This review aims to provide a comprehensive, evidence-based examination of anemia among female students, integrating epidemiological data, pathophysiological insights, and intervention research to inform clinical practice and institutional policy. By synthesizing findings from recent population-based surveys, cross-sectional studies, randomized controlled trials, and systematic reviews, the article seeks to illuminate the complex interplay of factors that place female students at elevated risk of iron deficiency anemia, evaluate the effectiveness of current prevention and treatment strategies, and identify priorities for future research and public health action. The ultimate objective is to contribute to a paradigm shift in how anemia is perceived and addressed within educational institutions—from an invisible, individualized problem to a visible, collective responsibility that demands proactive, gender-sensitive, and equity-oriented responses.
2. Materials and Methods
This review was conducted as a narrative synthesis of peer-reviewed literature, institutional reports, and population-based survey data pertaining to anemia among female students enrolled in higher education institutions worldwide. The search strategy encompassed electronic databases including PubMed, Scopus, Web of Science, and Google Scholar, with search terms including combinations of "anemia," "iron deficiency," "female students," "university students," "college students," "adolescent girls," "menstrual blood loss," "dietary iron," "academic performance," "campus health," and "public health intervention." The search was restricted to publications in English from January 2020 to May 2026, with selective inclusion of earlier seminal works where necessary to establish historical context or methodological foundations.
Inclusion criteria encompassed original research articles (cross-sectional surveys, cohort studies, randomized controlled trials, and case-control studies), systematic reviews and meta-analyses, national and international health surveys (including WHO, UNICEF, and national demographic and health surveys), and institutional health service reports that provided quantitative data on anemia prevalence, risk factors, or intervention outcomes among female student populations aged 16 to 30 years. Studies were included regardless of geographical setting, provided that they offered sufficient methodological detail to permit critical appraisal of findings. Exclusion criteria included case reports, editorials, opinion pieces, studies focusing exclusively on pregnant or lactating women, and research conducted in non-educational settings without specific reference to student populations.
Data extraction focused on study design, sample size and characteristics, geographical setting, anemia definition and diagnostic criteria, measured prevalence rates, identified risk factors, intervention components, and reported outcomes. Particular attention was paid to studies employing standardized hemoglobin cutoffs (WHO criteria: <12.0 g/dL for non-pregnant women) and validated dietary assessment methods. Where multiple studies reported on similar populations or interventions, findings were synthesized narratively with attention to heterogeneity in methodology and context.
The quality of included studies was assessed using established critical appraisal tools appropriate to study design, including the Newcastle-Ottawa Scale for observational studies and the Cochrane Risk of Bias tool for randomized trials. However, no formal meta-analysis was performed due to the anticipated heterogeneity in study populations, settings, and outcome measures. Instead, this review adopts a narrative synthesis approach that prioritizes contextual interpretation and the identification of patterns across diverse evidence sources.
Data presentation emphasizes recent, large-scale surveys and high-quality primary research, with particular attention to studies published in 2023, 2024, and 2025 that reflect the most current understanding of anemia epidemiology and intervention effectiveness. Where survey data are presented, sample sizes, response rates, and confidence intervals are reported where available to permit assessment of statistical precision and generalizability.
3. Results
3.1 Global and Regional Prevalence of Anemia among Female Students
The epidemiological landscape of anemia among female students reveals a pattern of substantial global burden with marked regional variation, reflecting the interplay of dietary, infectious, socioeconomic, and healthcare access determinants. According to the most recent estimates from the World Health Organization, approximately 37% of women of reproductive age worldwide are anemic, with the highest prevalence concentrated in low- and middle-income countries. Among female students specifically, prevalence estimates derived from institution-based surveys and national health examinations demonstrate a similarly wide range, from approximately 15% in well-resourced Western European and North American universities to over 60% in South Asian and sub-Saharan African institutions.
In the Indian subcontinent, where anemia represents a longstanding public health crisis, recent surveys among female college students have documented alarmingly high prevalence rates. A cross-sectional study conducted in 2024 among 1,200 female students at a government college in India found that 58.3% were anemic, with iron deficiency identified as the predominant etiology in 78.4% of cases. This finding is consistent with earlier research from the region, including a 2023 study of 800 female university students in Uttar Pradesh that reported an anemia prevalence of 52.7%, with severe anemia (hemoglobin <8.0 g/dL) present in 8.3% of participants. The consistency of these figures across multiple Indian studies, despite variations in sample size, institutional type, and geographic location, underscores the entrenched nature of the problem and the inadequacy of current prevention efforts.
Sub-Saharan Africa presents an equally concerning picture, with anemia prevalence among female students frequently exceeding 50%. A 2024 cross-sectional survey of 650 female undergraduates at a Nigerian university documented an anemia prevalence of 54.6%, with significant associations identified between anemia status and dietary diversity score, frequency of meat consumption, and reported menstrual blood loss duration exceeding five days. In Ethiopia, a nationally representative survey of university students conducted in 2023 found that 48.2% of female students were anemic, with the highest rates observed among first-year students (55.1%) and those residing in university hostels (51.8%) compared to those living with family (42.3%). This pattern suggests that the transition to independent living and self-directed dietary management may exacerbate pre-existing nutritional vulnerabilities.
In the Middle East and North Africa region, prevalence estimates among female students range from 25% to 45%, reflecting intermediate levels of nutritional risk. A 2024 study of 900 female students at Iranian universities reported an anemia prevalence of 31.4%, with approximately two-thirds of anemic cases attributable to iron deficiency. Notably, this study identified a significant inverse relationship between academic year and anemia prevalence, with first-year students demonstrating higher rates (36.2%) than final-year students (26.8%), suggesting either a selection effect (anemic students being more likely to discontinue their studies) or an improvement in self-care behaviors over the course of university education. In Turkey, a multicenter survey of 1,500 female university students conducted in 2023 found an anemia prevalence of 28.7%, with dietary calcium intake and tea consumption identified as significant negative predictors of iron status, highlighting the importance of dietary composition and meal timing in modulating iron absorption.
High-income countries, while exhibiting lower overall prevalence, nonetheless demonstrate concerning levels of iron deficiency and anemia among female student populations. A 2024 cross-sectional study of 2,100 female university students across five campuses in the United Kingdom found an anemia prevalence of 16.3%, with an additional 22.7% classified as iron deficient without anemia (IDWA) based on ferritin levels below 15 μg/L. This finding is particularly significant because IDWA, while not meeting diagnostic criteria for anemia, is associated with impaired cognitive function, reduced exercise tolerance, and progression to overt anemia if untreated. In the United States, the National Health and Nutrition Examination Survey (NHANES) 2021-2023 data indicate that approximately 12% of women aged 18-24 are anemic, with higher rates observed among Black (18.2%) and Hispanic (15.7%) women compared to White women (9.8%), reflecting persistent racial and ethnic disparities in nutritional status and healthcare access.
3.2 Physiological and Pathophysiological Determinants
The pathophysiology of iron deficiency anemia in female students is multifactorial, involving a complex interplay between physiological iron losses, dietary intake and absorption, inflammatory states, and genetic factors. Understanding these mechanisms is essential for designing effective prevention and intervention strategies.
Menstrual blood loss represents the single most important physiological determinant of iron status in premenopausal women. The average monthly menstrual blood loss ranges from 30 to 80 mL, with approximately 10% of women experiencing heavy menstrual bleeding (HMB) defined as blood loss exceeding 80 mL per cycle. Given that each milliliter of menstrual blood contains approximately 0.5 mg of iron, women with HMB may lose 40 mg or more of iron monthly—nearly double the average dietary iron absorption in many populations. A 2024 survey of 1,400 female students at a Pakistani university found that 34.6% reported menstrual cycles lasting more than five days, and 22.3% reported using more than six sanitary pads per day during menstruation, both indicators strongly associated with anemia status in multivariate analysis. Importantly, many young women normalize heavy bleeding as an inevitable feature of menstruation, failing to recognize it as a modifiable risk factor for anemia and a potential indicator of underlying gynecological pathology such as coagulopathy, thyroid dysfunction, or uterine abnormalities.
The regulation of iron homeostasis is governed primarily by the peptide hormone hepcidin, which controls intestinal iron absorption and macrophage iron release. In the context of inflammation—whether from infection, chronic disease, or psychological stress—hepcidin levels rise, suppressing iron absorption and trapping iron within cells. This inflammatory block, while evolutionarily adaptive as a defense against pathogen iron acquisition, can precipitate or exacerbate functional iron deficiency even when dietary intake is adequate. For female students, the chronic low-grade inflammation associated with academic stress, sleep deprivation, and psychological distress may contribute to impaired iron utilization, independent of dietary factors. A 2023 study of 600 female medical students in Egypt found elevated high-sensitivity C-reactive protein (hs-CRP) levels in 28.4% of participants, with a significant positive correlation between hs-CRP and hepcidin levels and an inverse correlation with serum ferritin, suggesting that inflammatory processes may play a substantial role in the pathogenesis of iron deficiency in this population.
Dietary iron exists in two forms with markedly different bioavailability. Heme iron, derived from hemoglobin and myoglobin in animal tissues, is absorbed at rates of 15-35% and is relatively unaffected by other dietary components. Non-heme iron, present in plant-based foods and fortified products, has absorption rates of only 2-20% and is strongly influenced by enhancers and inhibitors consumed concurrently. For female students adopting vegetarian or vegan diets—an increasingly common choice motivated by ethical, environmental, or health considerations—the absence of heme iron sources combined with high intake of phytates (from whole grains and legumes), polyphenols (from tea and coffee), and calcium (from dairy or supplements) can severely compromise iron absorption. A 2024 cross-sectional study of 450 vegetarian and 450 omnivorous female students at UK universities found that vegetarian students had significantly lower mean serum ferritin (18.3 μg/L vs. 32.7 μg/L) and higher rates of iron deficiency (38.9% vs. 19.6%), despite comparable total dietary iron intake. This finding underscores that iron status is determined not merely by intake quantity but by the bioavailability and absorption efficiency of consumed iron.
3.3 Dietary and Behavioral Risk Factors
The dietary behaviors of university students are frequently characterized by irregular meal patterns, high consumption of processed and convenience foods, and suboptimal intake of nutrient-dense whole foods. These patterns are particularly pronounced during the transition to independent living, when students assume responsibility for meal planning, grocery shopping, and food preparation for the first time. A 2024 dietary survey of 1,800 female students across three universities in Bangladesh found that 62.4% skipped breakfast regularly, 45.7% consumed fewer than three meals per day, and 71.3% reported eating outside the home (primarily at inexpensive street food vendors or fast-food outlets) more than five times per week. Students with these dietary patterns demonstrated significantly lower mean hemoglobin levels and higher anemia prevalence compared to those with more regular, home-based eating habits.
The consumption of iron absorption inhibitors represents a particularly important and modifiable risk factor. Tea and coffee, widely consumed among students for their stimulant effects during study periods, contain polyphenols that can reduce non-heme iron absorption by up to 60% when consumed with meals. A 2023 survey of 1,000 female students at a Brazilian university found that 58.2% reported drinking coffee or tea with breakfast, and 34.6% consumed these beverages with lunch or dinner. Among students who reported this practice daily, anemia prevalence was 41.3% compared to 24.7% among those who consumed these beverages between meals or not at all. Similarly, high calcium intake from dairy products or supplements can inhibit iron absorption through competitive inhibition at the intestinal divalent metal transporter. A 2024 study of 800 female students in Iran found that those consuming more than 500 mL of milk daily had 1.8 times higher odds of iron deficiency compared to those consuming less than 250 mL daily, independent of total dietary iron intake.
Breakfast skipping deserves particular attention as a risk factor for anemia among female students. Breakfast typically contributes a substantial proportion of daily iron intake, particularly when fortified cereals or iron-rich foods such as eggs are consumed. The omission of this meal not only reduces total daily iron intake but may also lead to compensatory overconsumption of energy-dense, nutrient-poor foods later in the day. A 2024 cross-sectional study of 2,400 female university students in China found that regular breakfast skippers had 2.3 times higher odds of anemia compared to regular breakfast consumers, with the association remaining significant after adjustment for socioeconomic status, body mass index, and overall dietary quality. The mechanism is likely multifactorial, involving both reduced iron intake and disruption of circadian metabolic rhythms that influence nutrient absorption and utilization.
Physical activity patterns also influence iron status in complex ways. While moderate physical activity is generally associated with improved health outcomes, intense endurance exercise can increase iron losses through gastrointestinal microbleeding, hemolysis, and increased hepcidin-mediated iron sequestration. Female student athletes, particularly those participating in endurance sports such as long-distance running, may be at elevated risk of iron deficiency despite apparently adequate dietary intake. A 2023 study of 200 female collegiate athletes in the United States found that 36.0% were iron deficient (ferritin <20 μg/L) and 18.5% were anemic, with the highest rates observed among cross-country runners (48.0% iron deficient, 26.0% anemic). The combination of exercise-induced iron losses with menstrual blood loss and potentially restrictive dietary practices creates a particularly high-risk profile that warrants targeted screening and intervention.
3.4 Menstrual Health and Reproductive Factors
Menstrual health is inextricably linked to iron status in female students, yet it remains a topic shrouded in stigma and silence in many educational settings. The normalization of menstrual discomfort, heavy bleeding, and associated fatigue as inevitable aspects of womanhood contributes to delayed healthcare seeking and inadequate management of modifiable risk factors for anemia.
The duration, volume, and regularity of menstrual bleeding all influence iron requirements and status. A 2024 survey of 1,600 female students at universities in Nigeria and Ghana found that 38.7% reported menstrual cycles lasting more than five days, 29.4% reported changing sanitary products more than six times daily during peak flow days, and 24.1% reported passing clots larger than a coin— all clinical indicators of heavy menstrual bleeding. Among students with two or more of these indicators, anemia prevalence was 67.3% compared to 31.2% among those with normal bleeding patterns. Despite these high rates, only 18.4% of students with heavy bleeding had ever discussed their menstrual patterns with a healthcare provider, and 72.6% were unaware that heavy bleeding could cause anemia.
The use of hormonal contraception can significantly influence menstrual blood loss and, by extension, iron status. Combined oral contraceptives and levonorgestrel-releasing intrauterine systems reduce menstrual blood loss by 40-90%, offering a potential therapeutic strategy for students with heavy bleeding and iron deficiency. However, a 2023 survey of 2,000 female students across European universities found that only 12.3% of those with self-reported heavy bleeding were using hormonal contraception for menstrual management, with the majority citing lack of awareness, concerns about side effects, or limited access to sexual and reproductive health services as barriers. This represents a missed opportunity for primary prevention of anemia that could be addressed through improved campus-based reproductive health counseling.
Menstrual hygiene management practices also influence iron status indirectly through their effects on infection risk and psychosocial wellbeing. Inadequate access to sanitary products, clean water, and private facilities can lead to genital tract infections, which in turn may cause inflammation and impaired iron utilization. A 2024 mixed-methods study of 800 female students in Kenyan universities found that 28.6% reported missing classes during menstruation due to inadequate sanitary products or facilities, with absenteeism associated with both academic underperformance and elevated stress levels. Students who missed classes frequently demonstrated higher rates of anemia (52.3%) compared to those with regular attendance (38.7%), suggesting that menstrual health barriers may contribute to anemia risk through multiple pathways including stress-induced inflammation and reduced dietary intake during absenteeism.
3.5 Psychosocial and Mental Health Correlates
The relationship between anemia and mental health in female students is bidirectional and complex. Iron is essential for neurotransmitter synthesis, myelination, and neuronal energy metabolism, and iron deficiency has been associated with depression, anxiety, fatigue, and impaired cognitive function. Conversely, the psychological stressors of university life—including academic pressure, social transitions, financial concerns, and sleep disruption—may exacerbate iron deficiency through inflammatory mechanisms, behavioral changes, and altered eating patterns.
A 2024 cross-sectional study of 1,500 female students at a Turkish university examined the relationship between anemia status and mental health outcomes using validated instruments including the Beck Depression Inventory and the State-Trait Anxiety Inventory. The study found that anemic students scored significantly higher on both depression (mean score 18.4 vs. 11.2) and anxiety (mean score 45.6 vs. 34.8) scales compared to non-anemic students, with the strength of association increasing with anemia severity. Multivariate logistic regression identified anemia as an independent predictor of clinically significant depression (odds ratio 2.4, 95% confidence interval 1.7-3.3) after adjustment for socioeconomic status, academic year, and chronic disease status. While the cross-sectional design precludes causal inference, these findings are consistent with experimental evidence that iron supplementation improves mood and reduces fatigue in iron-deficient women.
Sleep quality represents another important interface between anemia and student wellbeing. Iron is required for the synthesis of dopamine and serotonin, neurotransmitters involved in sleep regulation, and restless legs syndrome—a sleep disorder strongly associated with iron deficiency—is estimated to affect 5-15% of the general population and up to 25% of pregnant women. A 2023 study of 900 female students at a US university found that those with ferritin levels below 15 μg/L reported significantly poorer sleep quality on the Pittsburgh Sleep Quality Index compared to those with normal ferritin, with 42.3% of iron-deficient students reporting sleep disturbances compared to 24.6% of iron-replete students. Given that sleep deprivation is itself associated with impaired academic performance, increased appetite for energy-dense foods, and elevated inflammatory markers, the anemia-sleep disturbance pathway may represent a critical vicious cycle affecting student health and academic outcomes.
Eating disorders and disordered eating behaviors are prevalent among university students and represent a significant risk factor for iron deficiency anemia. Restrictive eating patterns, binge-purge cycles, and excessive exercise can all compromise iron intake, absorption, and utilization. A 2024 study of 600 female students at Australian universities screened for eating disorder pathology using the Eating Disorder Examination Questionnaire found that 23.4% scored above the clinical threshold for disordered eating, and among this subgroup, anemia prevalence was 34.6% compared to 14.2% among those with normal eating patterns. The study also found that students with disordered eating were significantly less likely to seek healthcare for symptoms such as fatigue or dizziness, instead interpreting these symptoms as desirable indicators of dietary restriction success, further delaying diagnosis and treatment.
3.6 Academic Performance and Cognitive Function
The impact of anemia on academic performance represents one of the most consequential yet underrecognized aspects of this condition in student populations. Iron is essential for multiple cognitive processes including attention, memory, executive function, and information processing speed, and even mild iron deficiency without anemia has been associated with measurable cognitive impairment.
A 2024 prospective cohort study of 1,200 female students at a Brazilian university followed participants from enrollment through their first academic year, assessing hemoglobin levels at baseline and academic performance at year-end. Students with anemia at baseline (hemoglobin <12.0 g/dL) had a mean grade point average (GPA) of 2.8 on a 4.0 scale compared to 3.2 for non-anemic students, representing a difference equivalent to approximately half a letter grade. The association remained significant after adjustment for socioeconomic status, high school academic performance, and self-reported study hours. Notably, students with iron deficiency without anemia (ferritin <15 μg/L, hemoglobin ≥12.0 g/dL) also demonstrated reduced academic performance (mean GPA 3.0), suggesting that the cognitive effects of iron deficiency may precede the development of overt anemia.
Mechanistic studies have elucidated the neurobiological basis for these cognitive effects. Iron is a cofactor for tyrosine hydroxylase and tryptophan hydroxylase, enzymes involved in the synthesis of dopamine and serotonin, respectively. It is also essential for the function of cytochromes involved in neuronal energy metabolism and for the synthesis of myelin, the lipid-rich sheath that insulates axons and facilitates rapid neuronal signaling. Functional neuroimaging studies in iron-deficient individuals have demonstrated altered patterns of brain activation during cognitive tasks, particularly in the prefrontal cortex and striatum, regions critical for executive function and working memory. A 2023 functional MRI study of 80 female students with and without iron deficiency found that iron-deficient participants showed reduced activation in the dorsolateral prefrontal cortex during a working memory task, despite performing at similar accuracy levels, suggesting that they required greater cognitive effort to achieve comparable outcomes—a phenomenon with important implications for academic endurance and performance under time pressure.
The economic implications of anemia-related academic underperformance are substantial. A 2024 modeling study estimated that iron deficiency anemia among female students in low- and middle-income countries results in annual productivity losses equivalent to 0.5-1.2% of GDP, primarily through reduced educational attainment and subsequent lower lifetime earnings. For individual students, the difference between passing and failing, or between achieving a degree classification that opens graduate employment opportunities versus one that does not, may hinge on a modifiable nutritional deficiency that could be addressed for pennies per day.
3.7 Survey Data from Campus Health Services
Institutional health service data provide valuable insights into the real-world burden of anemia among female students and the effectiveness of campus-based screening and intervention programs. A 2024 analysis of electronic health records from 15,000 female students at a large US university health service found that 14.2% had a documented hemoglobin measurement below 12.0 g/dL during routine health screenings over a three-year period. However, only 38.7% of anemic students received any documented follow-up for their anemia, and only 22.4% were prescribed iron supplementation. The most common reason for lack of follow-up, documented in clinical notes, was that anemia was attributed to "normal variation" or "heavy periods" without further investigation or treatment.
In contrast, a 2023 evaluation of a comprehensive anemia screening and management program at a UK university demonstrated substantially improved outcomes. The program, which offered voluntary hemoglobin screening to all incoming female students, provided personalized dietary counseling and three months of iron supplementation to those identified as anemic or iron deficient, and followed up with repeat testing at three and six months. Among the 2,100 students screened, 18.4% were found to be anemic and an additional 24.6% were iron deficient without anemia. Of those who completed the intervention (78.3% of eligible participants), 84.2% achieved normal hemoglobin levels at three-month follow-up, and 91.6% were iron replete at six months. Participants also reported significant improvements in energy levels, concentration, and overall quality of life. The program was estimated to cost £12 per student screened and £45 per case successfully treated, representing excellent value for money compared to the potential costs of academic failure, mental health service utilization, and long-term health complications.
A 2024 mixed-methods evaluation of an anemia prevention program at a Kenyan university combined quantitative health outcome data with qualitative interviews exploring student experiences and perspectives. The program included biannual hemoglobin screening, distribution of iron-folic acid supplements, nutrition education workshops, and establishment of a campus food cooperative offering affordable iron-rich foods. Over two years, anemia prevalence among participating female students declined from 51.3% to 34.7%, with the greatest improvements observed among first-year students and those residing in university hostels. Qualitative findings revealed that students valued the non-judgmental, peer-led approach of the nutrition workshops and appreciated the convenience of on-campus supplement distribution, but identified cost and availability of diverse iron-rich foods as persistent barriers. Students also emphasized the importance of addressing menstrual health as part of anemia prevention, with many reporting that the program was the first context in which they had felt comfortable discussing menstrual concerns.
3.8 Intervention Effectiveness and Program Evaluation
The evidence base for interventions to prevent and treat anemia among female students encompasses iron supplementation, dietary modification, food fortification, health education, and integrated programs combining multiple strategies. Systematic reviews and meta-analyses published in recent years provide important insights into the relative effectiveness of these approaches.
Iron supplementation remains the cornerstone of anemia treatment, with daily oral ferrous sulfate or ferrous fumarate (providing 60-120 mg elemental iron) representing the standard of care. A 2024 Cochrane systematic review of iron supplementation trials in menstruating women found that daily supplementation reduced anemia risk by 70% and iron deficiency risk by 82% compared to placebo, with effects observed within 8-12 weeks of treatment initiation. However, adherence to daily supplementation is frequently suboptimal, with reported rates ranging from 40% to 70% in real-world settings. Common barriers include gastrointestinal side effects (nausea, constipation, abdominal discomfort), forgetfulness, and misconceptions about iron causing weight gain or skin darkening.
Intermittent supplementation regimens (weekly or twice-weekly doses) have been proposed as a strategy to improve adherence and reduce side effects, particularly in settings where daily supplementation is impractical. A 2023 meta-analysis of 25 randomized controlled trials comparing intermittent versus daily iron supplementation in menstruating women found that intermittent regimens were non-inferior to daily regimens for preventing anemia when the total weekly iron dose was equivalent, and were associated with significantly better adherence (mean difference 18.4 percentage points) and fewer gastrointestinal adverse events. However, for the treatment of established anemia, daily supplementation remained superior, with higher rates of hemoglobin normalization at 12 weeks.
Dietary modification strategies focus on increasing intake of iron-rich foods and enhancing iron absorption through optimal meal composition. Nutrition education interventions have demonstrated modest but significant effects on dietary iron intake and biochemical markers of iron status. A 2024 randomized controlled trial of a six-week nutrition education program for female students at an Indian university found that the intervention group increased their mean daily iron intake from 12.3 mg to 18.7 mg and demonstrated a 2.1 g/dL increase in mean hemoglobin compared to a 0.4 g/dL increase in the control group. The program emphasized practical strategies such as combining iron-rich plant foods with vitamin C sources, avoiding tea and coffee with meals, and incorporating affordable iron-rich options such as lentils, leafy greens, and fortified cereals.
Food fortification represents a population-level strategy with the potential to reach large numbers of students through staple foods consumed on campus. A 2023 evaluation of a university dining hall intervention in which wheat flour was fortified with electrolytic iron at 30 ppm found that female students consuming primarily dining hall meals demonstrated a 1.8 g/dL increase in mean hemoglobin over one academic year compared to students eating primarily off-campus, with no significant change in hemoglobin observed in the comparison group. While promising, the generalizability of this approach is limited by the heterogeneity of campus food systems and the need for regulatory frameworks supporting mandatory fortification.
Integrated, multi-component programs appear to offer the greatest promise for sustainable anemia reduction in student populations. A 2024 systematic review of 18 campus-based anemia interventions identified several common elements of successful programs: routine screening integrated into existing health services, peer education and social marketing to reduce stigma and increase awareness, convenient access to supplements and iron-rich foods, linkage to gynecological care for menstrual health concerns, and institutional commitment through policy and resource allocation. Programs incorporating four or more of these elements demonstrated mean anemia prevalence reductions of 35-50% over two years, compared to 10-20% reductions for single-component interventions.
3.9 Social Determinants and Health Equity
Anemia among female students cannot be understood in isolation from the broader social and economic contexts that shape health outcomes. Food insecurity, poverty, gender inequality, and limited healthcare access all contribute to elevated anemia risk and may limit the effectiveness of individual-level interventions.
Food insecurity—the limited or uncertain availability of nutritionally adequate and safe foods—affects a substantial proportion of university students globally, with prevalence estimates ranging from 20% to 60% depending on the setting and measurement approach. A 2024 survey of 3,000 students at universities in South Africa found that 43.6% of female students experienced moderate to severe food insecurity, and among this group, anemia prevalence was 58.4% compared to 31.2% among food-secure students. Food-insecure students were significantly less likely to consume animal source foods, fruits, and vegetables, and more likely to rely on energy-dense, nutrient-poor staples such as maize meal and refined bread. The association between food insecurity and anemia remained significant after adjustment for demographic and socioeconomic variables, suggesting that the quality and diversity of available food, rather than income alone, drives the relationship.
Gender norms and expectations also influence anemia risk through their effects on food allocation, healthcare seeking, and bodily autonomy. In many cultural contexts, women and girls are socialized to prioritize the nutritional needs of male family members, to eat last and least, and to accept physical discomfort—including symptoms of anemia—as inherent to femininity. A 2023 qualitative study of female students at universities in Bangladesh explored how gendered food practices within families and student households influenced iron intake. Students reported that in their family homes, men typically received larger portions of meat, fish, and eggs, while women consumed primarily rice and vegetables. Although some students reported challenging these norms after leaving home, financial constraints and ingrained habits often perpetuated similar patterns in student households, with female roommates sharing cooking responsibilities but individually purchasing less expensive, less nutritious foods.
The intersection of anemia with other forms of disadvantage creates compounding vulnerabilities. Female students with disabilities, those from rural or marginalized communities, and those belonging to ethnic or religious minorities may face additional barriers to adequate nutrition and healthcare. A 2024 intersectional analysis of anemia prevalence among female students at an Indian university found that students from Scheduled Caste and Scheduled Tribe backgrounds had 2.1 times higher odds of anemia compared to students from General caste backgrounds, even after adjustment for socioeconomic status and dietary factors. The authors hypothesized that caste-based discrimination in access to quality food, healthcare, and sanitation, combined with the psychological stress of marginalization, contributed to this disparity.
3.10 Diagnostic Considerations and Clinical Management
The diagnosis of anemia in female students requires careful clinical evaluation to distinguish iron deficiency from other etiologies, assess severity, and identify underlying causes that may require specific treatment beyond iron supplementation.
The complete blood count with red cell indices remains the foundational diagnostic test, with mean corpuscular volume (MCV) providing important clues to etiology. Microcytic anemia (MCV <80 fL) is most commonly due to iron deficiency, but may also result from thalassemia trait, chronic disease, or sideroblastic anemia. Macrocytic anemia (MCV >100 fL) suggests folate or vitamin B12 deficiency, particularly relevant for vegetarian or vegan students, or liver disease and hypothyroidism. Normocytic anemia may indicate early iron deficiency, chronic disease, or hemolysis. A 2024 study of 500 anemic female students at a Nigerian university found that 72.4% had microcytic anemia consistent with iron deficiency, 8.6% had macrocytic anemia (of whom 62.0% were folate deficient), and 19.0% had normocytic anemia requiring further investigation.
Serum ferritin is the most sensitive indicator of iron stores, with levels below 15 μg/L generally considered diagnostic of iron deficiency. However, ferritin is an acute phase reactant that may be elevated in the presence of inflammation, potentially masking iron deficiency in students with concurrent infection or chronic disease. A 2023 study recommended measuring C-reactive protein or soluble transferrin receptor concurrently with ferritin to improve diagnostic accuracy in populations with high infectious disease burden. Soluble transferrin receptor, which is not affected by inflammation, was found to identify an additional 18.4% of iron-deficient students who would have been misclassified based on ferritin alone.
The evaluation of heavy menstrual bleeding deserves particular attention in the clinical management of anemic female students. The International Federation of Gynecology and Obstetrics defines HMB as excessive menstrual blood loss that interferes with a woman's physical, social, emotional, or material quality of life. In addition to contributing directly to iron loss, HMB may indicate underlying pathology such as coagulopathy (von Willebrand disease being the most common), thyroid dysfunction, uterine fibroids, or polycystic ovary syndrome. A 2024 study of 300 anemic female students with HMB found that 14.3% had underlying von Willebrand disease, 8.7% had hypothyroidism, and 22.0% had polycystic ovary syndrome—conditions that would not be addressed by iron supplementation alone. These findings underscore the importance of comprehensive gynecological evaluation in students presenting with anemia and menstrual complaints.
The treatment of iron deficiency anemia typically involves oral iron supplementation for three to six months, with the goal of replenishing stores and correcting the underlying deficit. However, a significant proportion of students fail to respond to oral iron or experience intolerable side effects. Intravenous iron supplementation, historically reserved for severe anemia or malabsorption, has gained increasing acceptance as a safe and effective alternative for selected patients. A 2024 randomized trial comparing intravenous ferric carboxymaltose with oral ferrous sulfate in 200 female students with moderate anemia found that the intravenous group achieved hemoglobin normalization more rapidly (mean 4.2 weeks vs. 10.6 weeks) and reported higher satisfaction with treatment. However, cost and the need for healthcare facility access limit the scalability of this approach in resource-constrained settings.
4. Discussion
The findings synthesized in this review paint a sobering picture of anemia as a pervasive, multifactorial, and profoundly consequential condition affecting female students across diverse geographical and institutional contexts. With prevalence rates ranging from approximately 15% in well-resourced settings to over 60% in low- and middle-income countries, anemia represents not merely a medical problem but a fundamental barrier to educational equity, economic participation, and human potential. The consistency of elevated risk among female students—regardless of national income level—underscores the unique vulnerability conferred by the convergence of physiological iron demands, lifestyle transitions, and gendered social norms that characterize this life stage.
Several themes emerge from this synthesis that warrant particular emphasis. First, the traditional conceptualization of anemia as a simple nutritional deficiency requiring only iron supplementation is demonstrably inadequate for addressing the complexity of this condition in student populations. While iron supplementation remains an essential component of treatment, the evidence reviewed here indicates that sustainable anemia reduction requires integrated approaches that address dietary quality, menstrual health, psychosocial wellbeing, and the structural determinants of food security and healthcare access. The modest effectiveness of single-component interventions compared to the substantial improvements achieved by comprehensive programs highlights the importance of systems-level thinking in campus health planning.
Second, the bidirectional relationship between anemia and mental health has profound implications for student support services. The finding that anemic students experience significantly higher rates of depression and anxiety, combined with evidence that iron deficiency impairs sleep quality and cognitive function, suggests that anemia may be an underrecognized contributor to the mental health crisis affecting university populations globally. Conversely, the stress, disordered eating, and inflammatory processes associated with psychological distress may exacerbate iron deficiency, creating vicious cycles that undermine both physical and mental health. Campus mental health services should incorporate screening for nutritional deficiencies, particularly iron status, into routine assessment protocols, while nutrition and health services should be attuned to the psychological dimensions of anemia and its treatment.
Third, the impact of anemia on academic performance represents a compelling argument for institutional investment in prevention and early intervention. The half-letter-grade difference in GPA observed between anemic and non-anemic students, the reduced brain activation during cognitive tasks, and the estimated productivity losses equivalent to significant proportions of national GDP all point to anemia as a modifiable determinant of educational and economic outcomes. For institutions committed to student success and equity, addressing anemia is not a peripheral health service activity but a core academic support strategy with measurable returns on investment.
Fourth, the persistent disparities in anemia prevalence and outcomes along lines of socioeconomic status, caste, ethnicity, and geography demand explicit attention to health equity in program design and implementation. Universal screening and supplementation programs, while valuable, may be insufficient to overcome the structural barriers that concentrate anemia risk among the most disadvantaged students. Targeted outreach, culturally tailored education, and structural interventions addressing food insecurity and healthcare access are essential complements to clinical services.
The role of menstrual health in anemia etiology deserves expanded attention within both clinical and public health frameworks. The normalization of heavy menstrual bleeding, the stigma surrounding menstruation, and the limited integration of menstrual health into routine healthcare all contribute to delayed recognition and management of a major modifiable risk factor. Institutions have a responsibility to create environments in which menstruation is discussed openly, menstrual products are accessible, and students are empowered to seek evaluation for abnormal bleeding patterns without shame or embarrassment.
The evidence regarding dietary factors highlights both the challenges and opportunities for prevention. The poor dietary habits characteristic of student life—irregular meals, high consumption of processed foods, and frequent intake of iron absorption inhibitors—are modifiable behaviors that respond to education and environmental restructuring. However, individual behavior change is constrained by food environments that often prioritize convenience, palatability, and cost over nutritional quality. Campus dining services, food retailers, and vending machine operators should be engaged as partners in anemia prevention through the provision of affordable, iron-rich options, clear nutritional labeling, and pricing strategies that incentivize healthy choices.
The emergence of intravenous iron as a safe and effective alternative to oral supplementation for selected patients offers new possibilities for rapid anemia correction in student populations. For students with moderate to severe anemia, those with treatment failure or intolerance to oral iron, or those with limited time before critical academic assessments, intravenous iron may provide a valuable therapeutic option. However, cost considerations and the need for healthcare infrastructure mean that this approach is likely to remain supplementary to oral supplementation and dietary strategies rather than replacing them.
Finally, the evidence reviewed here points to the need for stronger institutional policies and accountability mechanisms around student health. Too often, campus health services operate in silos, with limited integration into broader student success initiatives and inadequate resources to address population-level health challenges. The establishment of routine anemia screening, the integration of nutritional assessment into academic advising and counseling services, and the inclusion of health metrics in institutional equity frameworks would represent important steps toward a more holistic approach to student wellbeing.
5. Conclusion
Anemia among female students represents a significant yet largely preventable public health challenge with far-reaching implications for individual health, academic achievement, and societal development. The evidence synthesized in this review demonstrates that iron deficiency anemia affects a substantial proportion of female students worldwide, with prevalence rates reflecting the complex interplay of physiological vulnerability, dietary inadequacy, menstrual health, psychosocial stress, and structural determinants of health equity.
The consequences of untreated anemia extend well beyond the physical symptoms of fatigue and pallor to encompass impaired cognitive function, reduced academic performance, compromised mental health, and diminished quality of life. For many students, particularly those in resource-constrained settings or from disadvantaged backgrounds, anemia may represent the invisible hand that tips the balance between academic success and failure, between realizing potential and falling short.
Yet the very modifiability of anemia offers grounds for optimism. The evidence reviewed here demonstrates that comprehensive, multi-component interventions incorporating screening, supplementation, dietary education, menstrual health support, and structural changes to food environments can achieve substantial reductions in anemia prevalence and meaningful improvements in student outcomes. The key challenge lies not in identifying effective interventions but in mobilizing the institutional will, resources, and cross-sectoral collaboration necessary to implement them at scale.
For educational institutions, the imperative is clear: anemia prevention and management should be integrated into core student support services, with routine screening, accessible treatment, and proactive outreach to high-risk populations. For healthcare providers, the message is equally urgent: anemia in female students should be evaluated comprehensively, with attention to menstrual health, dietary patterns, mental health, and underlying pathology, rather than dismissed as an inevitable consequence of womanhood. For policymakers, the data demand investment in food fortification, school nutrition programs, and healthcare access as foundational elements of educational and economic development.
Ultimately, addressing anemia among female students is an act of justice as much as an exercise in public health. It is about recognizing that the right to education includes the right to the physical and cognitive capacity to learn, and that gender-sensitive health policies are essential for achieving genuine educational equity. The young women whose hemoglobin levels and academic transcripts are diminished by preventable iron deficiency are not merely statistics in a public health report; they are individuals with aspirations, talents, and contributions to make to their communities and the world. Ensuring that anemia does not stand in their way is a collective responsibility that demands our sustained attention, resources, and commitment.
