Abstract
BACKGROUND: Overweight and obesity among children and adolescents is a public health concern. OBJECTIVE: To assess the prevalence of overweight and obesity and its association with social and environmental determinants among the adolescent school children of Tirupati town of Andhra Pradesh, India. MATERIALS AND METHODS: Data was collected by interviewer-administered method from school children aged between 12 to 16 years. The sample consisted of 2258 subjects (1097 boys and 1161 girls). Overweight and obesity were defined by body mass index (BMI) based on the current method recommended by the Centre for Disease Control and Prevention 2000. Data on social and environmental determinants were collected by using a pre-tested and validated questionnaire. RESULTS: In the present sample, 11.2 percent and 4.8 percent of boys and 10.3 percent and 4.8 percent of girls were overweight and obese. The literacy level of parents, family income and child sleep duration significantly associated with overweight. Parental level of education was a risk factor for overweight (Mother: 1.570; 95% CI: 1.048-2.354). Similarly increase in family income (OR = 1.529; 95% CI: 1.089-2.148) and child sleep duration <7 hrs per day (OR = 2.006; 95% CI: 1.194-3.371) raised children's association in gaining weight. CONCLUSION: Our study reinforces the burgeoning prevalence of overweight and obesity among the adolescents. Interventional measures taken should consider family, school and physical environment to check the problem of overweight/obesity.
