## TL;DR

This study finds that iron deficiency is a major cause of anemia among adolescents in rural South India, especially in girls.

## Contribution

The study identifies iron deficiency as a key driver of anemia and highlights gender disparities in rural adolescent populations.

## Key findings

- Anemia was detected in 17.4% of adolescents, with higher prevalence in girls.
- Iron deficiency was indicated by lower serum iron and higher TIBC in anemic participants.
- Ferritin levels were significantly lower in anemic boys compared to anemic girls.

## Abstract

Anemia remains a significant adolescent health concern with multifactorial causes. Hence, 253 adolescents were assessed for anemia
using biochemical markers. Anemia was detected in 17.4% (95% CI: 6.3-28.5%) and it is more frequent among girls (20.16%) than boys
(14.7%). It correlated with faith (p=0.025) but not with socio-economic status, caste, or parental education. Anemic participants had
lower serum iron (p=0.001) and higher TIBC (p=0.025) suggesting iron deficiency. Ferritin was markedly lower in anemic boys compared to
anemic girls. Elevated TIBC in 78.26% reinforced the prevalence of iron deficiency. These findings highlight the need for targeted
nutritional interventions and screening programs.
