Factors associated with general and central obesity among Bengali adolescents: a cross-sectional study from North Bengal, India

Abstract

Adolescent obesity is an emerging global health problem. The present study aims to assess the prevalence and factors associated with general and central obesity among adolescents. A community-based cross-sectional study was conducted among 390 Bengali adolescents (aged 11–17 years) in Darjeeling districts. Three anthropometric measurements (height, weight, and waist circumference) were taken. Both general and central obesity were determined. ANOVA, t-test, chi-square and binary logistic regression (BLR) were performed. Findings revealed that the overall prevalence of general obesity (BMI-based) was 22.1% (boys 21.8%, girls 22.3%), and central obesity (based on waist circumference and waist-to-height ratio) was 44.6% (boys 43.1%, girls 46.1%), and 26.1% (boys 28.9%, girls 24.4%) respectively. Chi square revealed no significant association between gender and obesity (both general and central). Our findings showed that the number of siblings was the most crucial factor associated with adolescent obesity. Father’s and mother’s education, and family income were also found to be associated with central obesity. Proper awareness along with dietary and lifestyle changes can alter the situation.
