Prevalence and Correlates of Double and Triple Burden of Malnutrition Among Children and Adolescents in India: Comprehensive National Nutrition Survey

Abstract

BackgroundLimited information on the co-prevalence of undernutrition, micronutrient deficiencies, overnutrition, and abnormal levels of noncommunicable disease biomarkers at the same time in children and adolescents in India hinders efforts to comprehensively address their health. This study aims to examine the prevalence and correlates of double and triple burden of malnutrition (DBM, TBM) among children and adolescents (5-19 y) to inform policies and programs. MethodsA total of 17,599 children (5-9 y) and 16,184 adolescents (10-19 y) with available biomarker data from the Comprehensive National Nutrition Survey were included. Malnutrition was defined based on either undernutrition based on anthropometry, overnutrition/abnormal metabolic markers, and anemia/micronutrient deficiency. DBM was defined as the coexistence of any two forms of malnutrition. DBM+ was defined as the coexistence of undernutrition and/or micronutrient deficiency along with overnutrition. TBM was defined as having the coexistence of all three forms of malnutrition. The prevalence of DBM, DBM+ and TBM was estimated accounting for probabilistic selection. We used mixed effects binomial regression to determine correlates of DBM/TBM in children and adolescents separately. ResultsThe prevalence of DBM, DBM+ and TBM was 50.8%, 37.2%, and 14.4%, respectively, in children, and 53.4%, 36.1%, and 12.7%, respectively, in adolescents. The prevalence of DBM+ was significantly higher in children girls compared to boys. In children, being in a disadvantaged caste group, having a lower wealth index, having inadequate diet diversity, having no maternal schooling and having a recent history of acute illness were associated with DBM. In adolescents, being in a disadvantaged caste group, maternal occupation, and lower paternal age were correlated with DBM. A similar set of variables was associated with TBM in both age groups. ConclusionThe prevalence of DBM and TBM is substantial in children and adolescents in India and varies across states. Socioeconomic factors and acute illness were the main correlates for DBM and TBM.
