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.
