20.500.12556/DiRROS-29911 The prevalence of hair loss and its association with iron deficiency among adolescents in northern Sudan a school-based cross-sectional study Introduction: Alopecia and iron deficiency are significant public health issues in northern Sudan, and no research about this topic has been conducted. The aim is to examine the prevalence of iron deficiency and alopecia and associated factors among adolescents in northern Sudan. Methods: A cross-sectional study was conducted through a questionnaire and clinical examination. Results: A total of 312 adolescents participated: 147 males (47.1%) and 165 females (52.9%). Among them, 21.2% of adolescents exhibited alopecia. Females experienced higher rates of alopecia, with 93.9% affected compared to 6.1% of males. Serum ferritin was significantly lower in adolescents with alopecia compared to those without it (6.05 [2.58-12.63] vs. 9.40 [4.88-23.40] μg/l, p = 0.002). Multivariate analysis indicated that iron deficiency (adjusted odds ratio [AOR] = 1.97, 95% confidence interval [CI] = 1.04–3.71) was associated with alopecia. However, age, body mass index, and parental education level showed no association. Among the adolescents with alopecia, 27.3% had patchy alopecia, 37.9% had diffuse alopecia, and 34.8% had traction alopecia. Conclusions: There is a significant prevalence of adolescent alopecia, predominantly among females. Iron deficiency was a key factor associated with alopecia, underscoring the importance of nutritional monitoring in this population. adolescents alopecia iron deficiency age Sudan mladostniki alopecija pomanjkanje železa starost prekomerno izpadanje dlak Sudan true false true Združenje slovenskih dermatovenerologov Angleški jezik Slovenski jezik Neznano 2026-06-09 08:38:17 2026-06-15 19:31:54 2026-06-18 10:10:42 0000-00-00 00:00:00 2025 0 Ljubljana 0 str. 159-163 issue 4 Vol. 34 Dec. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-06-27 2025-11-07 2025-12-01 616.594.1 1318-4458 10.15570/actaapa.2025.29 276615427 RAZ_Alotaib_Moteb_Khalaf_2025.pdf RAZ_Alotaib_Moteb_Khalaf_2025.pdf 1 FC634F97FC8A23245A38969FB9EC59DC f5660804443d763d9d3f858aab7961092212834615b00394a2fdb4c3838cae50 268c96dc-68e0-11f1-aebd-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45496 https://acta-apa.mf.uni-lj.si/journals/acta-dermatovenerol-apa/papers/10.15570/actaapa.2025.29/actaapa.2025.29.pdf 0 d09a62b7-6ae4-11f1-be3d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45883 Združenje slovenskih dermatovenerologov Acta dermatovenerologica Alpina, Panonica et Adriatica 0 0 0
