Introduction: There was a scarcity of evidence on malnutrition-related factors among school-going children __ampersandsignge; 5 years in rural India. Objective: To assess the prevalence of stunting, underweight, wasting, and associated factors in school children of Anantapur district. Methods: This was a cross-sectional study conducted in a primary and secondary school located in rural settings of Anantapur district, Andhra Pradesh, India. A multi-stage random sampling technique was used to select the children for our study. The study was approved by the institutional review board and registered in the clinical trial registry of India. A suitable data collection form was used to collect information about socio-demographics, utilization of government nutritional programs, physical activity, and WHO anthropometric parameters. Chi-square Fisher exact test was used to associate predictors with malnutrition measures. The height-for-age z-score for stunting, weight-for-age z-score for undernutrition, and weight-for-height z-score for wasting were computed in WHO anthroplus software. Results: A total of 390 children have participated in the study with a mean age of 11.8__ampersandsignplusmn;2.4. The prevalence of stunting, underweight, and wasting among school children was 25.4%, 11.5%, and 17.7%, respectively. There was no significant difference in the nutritional measures among male and female children. Predictors like illiteracy of parents, joint family, and non-healthcare occupations were significantly associated with malnutrition characteristics among school-going children. Conclusion: The study concludes that the prevalence of stunting, underweight, wasting was existing among rural school-going children. Even government provides nutritional schemes to overcome malnutrition disorders in school children, there was still a gap to prevent nutritional disorders. Targeted educational programs on the importance of child nutrition and malnutrition complications towards mothers are required to improve nutritional status among school-going children
