Prevalence of overweight and obesity and associated demographic and health factors in India: Findings from Comprehensive National Nutrition Survey (CNNS)

Abstract

Background: Childhood obesity (5-9 years) in India is likely to contribute 11% to the global burden by 2030.

Methods: Data from India's Comprehensive National Nutrition Survey (CNNS, 2016-2018) was used to assess the prevalence and key associated factors of overweight and obesity. Multivariable logistic regression models were applied to identify potential determinants associated with being overweight and obese.

Results: Overweight prevalence (including obesity) varied from 1.6% (0-4 years) to 4.8% (10-19 years). The majority of states reported a higher proportion of adolescents overweight and obese, than younger age group 5-9 years. A significantly higher prevalence of children and adolescents with obesity was reported in higher wealth quintiles and residents of urban areas. The prevalence of overweight and obesity and associated demographic and health factors in India included: the presence of NCD risk factor (adolescents: 1.68, 95% CI [1.31-2.14]), micronutrient deficiency (5-9 years children: 1.72, 95% CI [1.30-2.28]), mother's education (5-9 years children: 4.84, 95% CI [2.92-8.03]; adolescents: 2.17, 95% CI [1.42-3.32]), wealth (adolescents: 1.92, 95% CI [1.16-3.19]), place of residence (5-9 years children: 1.68, 95% CI [1.39-2.03]; adolescents: 1.39, 95% CI [1.16-1.66]), child age (5-9 years children: 1.64, 95% CI [1.40-1.93], and screen-time (adolescents: 1.63, 95% CI [1.22-2.19].

Conclusion: The findings set out policy and research recommendations to pave the path for curtailing the increasing prevalence of overweight and obesity and achieving the World Health Assembly's Global Nutrition target of 'no increase in childhood overweight (Target 4) by 2025'.
