Objective: To understand the extent to which adolescent awareness about anaemia and anaemia prevention can be changed by nutrition messages received at school., Design: Mixed-methods pre-post intervention study., Setting: Three government schools in Bagalkot, Belagavi and Raichur districts of Karnataka, India., Population: Students of grade six and seven and teachers involved in implementing the intervention., Methods: An educational intervention was co-developed by school teachers and nutrition experts using locally adapted resource materials that consisted of lectures, role play and practical demonstrations. Seven half-hour educational sessions were delivered by school teachers over 7 weeks to 455 students. Pre- and post-intervention tests measured changes in adolescents' knowledge about anaemia. Semi-structured in-depth interviews with teachers and focus groups with students explored their reactions to the intervention., Main Outcome Measures: Knowledge score related to anaemia., Results: The percentage of children with correct scores increased by 7.3-49.0 percentage points for the tested questions after implementation of the intervention. The mean knowledge score increased by 3.67 ± 0.17 (p < 0.01). During interviews, teachers and students highlighted high acceptance of the intervention and materials, an increase in awareness, a positive attitude towards changing behaviour around diet, an increase in the demand for iron and folic acid supplements and improved sharing of messages learned with peers and families. Challenges expressed included need for further training, time limitations and hesitancy in teaching about menstruation and pregnancy., Conclusions: Educational interventions carried out for adolescents by teachers in schools are effective in improving awareness and attitude related to anaemia and its prevention., (© 2023 The Authors.

Background: For school-age children, a healthy transition from childhood to adolescence and adulthood depends on proper nutrition. Globally, most nutritional surveys focus on preschool and adolescents, neglecting school-age children. Recent studies have shown the prevalence of thinness among adolescents to be 26.5% in Karnataka. Similarly, among children aged < 5 years in the Raichur district, the prevalence of stunting, wasting, and being underweight was 39.8, 23.2, and 40.7%, respectively. The present study aimed to bridge the data gap between < 5 years of children and adolescents through a nutritional survey of school-going children in Raichur, one of the aspirational districts of India., Materials and Methods: A cross-sectional survey was conducted from January to March 2020 among rural school-age children ( n = 2700) in 30 villages of the Raichur district of Karnataka, India. The school children were selected through a multi-stage cluster sampling technique. The WHO Anthro-plus software was used for calculating the age and sex-specific Z-scores for weight-for-age (WAZ), height-for-age (HAZ), and BMI-for-age (BAZ)., Results: Of the 2,700 school-age children surveyed, the mean weight and height were 22.2 kg (+5.8) and 124.9 cm (+11.6), respectively. The prevalence of children having weight-for-age Z-scores < -2 SD (Underweight) was 45.3% (95% CI: 42.7%-47.8%). The magnitude of stunting and severe stunting was 19.5% (95% CI: 18.0%-21.0%) and 7.6% (95% CI: 6.6%-8.6%), respectively. The proportion of children with BMI for age Z-scores < -2SD (thinness) was 43% (95% CI: 41.1%-44.9%), with sub-district Sindhanur having a dual burden of malnutrition., Conclusion: Despite many flagship programs, the prevalence of undernutrition in school-age children remains a considerable public health problem in the aspirational district of Raichur, India. Furthermore, exploratory studies are recommended to identify the factors associated with undernutrition among school-age children and strategize evidence-based intervention., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Vastrad, Neelopant, Prasad, Kirte, Chandan, Barvaliya, Hatnoor, Shashidhar and Roy.)
