Abstract
Adolescent anaemia and malnutrition remain a major public health challenges in India Adolescence, yet district-level longitudinal evidence is limited. (10–19 years) is a nutritionally demanding period with high risk of anaemia and malnutrition. Therefore, it is of interest to assess baseline prevalence and follow-up changes in haemoglobin and nutritional status among adolescents enrolled in government and private schools of Guntur district during 2023–2025. At baseline, 6,175 adolescents were assessed, with an anaemia prevalence of 64% and a dual burden of malnutrition was observed, with 14% thin/severely thin and 24% overweight/obese. Among 618 adolescents successfully followed up, McNemar’s test demonstrated statistically significant worsening transitions for both anaemia (odds ratio = 3.3) and BMI status (odds ratio = 0.27). Strengthening longitudinal school health registries and sustained nutrition-specific interventions are recommended.
