Prevalence and predictors of the dual burden of malnutrition among adolescents in North India

Abstract

Background: Dual burden of malnutrition comprising of both under nutrition and over nutrition constitutes an important public health problem among Indian adolescents. Objective: The objective of this study is to determine the prevalence of dual burden of malnutrition (underweight and overweight/obesity) among adolescents and to understand the role of dietary habits and physical activity in this regard. Methodology: A cross-sectional survey was conducted in Shimla district of North India. A total of 720 adolescents aged 14-19 years were selected to participate in the study. Data were collected on sociodemographic status, physical activity, dietary intake, and anthropometry. Statistical analysis was done using Epi info software for windows (version 6.0, Centre for Disease Control, Atlanta, USA). Results: A total of 298 (41.3%) of the adolescents were suffering from dual burden of malnutrition. The binary logistic regression revealed a statistically significant positive association of overweight/obesity with frequent fast food consumption (odds ratio [OR] = 4.45, confidence interval [CI] = 2.42-8.18). Individuals consuming less salt in the diet had lower odds of being overweight/obese (OR = 0.47, CI = 0.25-0.87). Similarly, individuals frequently consuming fruits in the diet had lesser odds of being underweight (OR = 0.61, CI = 0.42-0.86). Conclusion: The high prevalence of the dual burden of malnutrition in this study stresses the need for policy makers in India to adapt the current adolescent program so as to focus on both ends of the nutrition spectrum.
