Factors associated with under-five mortality in Scheduled Tribes in India: An analysis of national family health survey-5 (2019-2021)

Background & objectives Under-five mortality is high among the Scheduled Tribes (ST) in India compared with the general population. This study examined the association of different maternal, child, socio demographic, and household factors associated with under-five mortality among Scheduled Tribes in India. Methods Data from the National Family and Health Survey (NFHS)-5 (2019-2021) for the ST, across all Indian States and Union Territories were used for analyses. Binary and multivariate logistic regression were performed to identify the association of maternal, child, socio-demographic, and household factors with under-five mortality among the ST population. Results Different maternal, child, socio demographic, and household factors were significantly associated with under-five mortality. The odds of under-five mortality were highest among women who gave birth to their children at home [Adjusted odds ratio (AOR): 1.42; 95% confidence interval (CI): 1.268-1.59] as compared with women who gave birth at institution. Literate women have lesser odds of under-five mortality than women with no formal education (AOR: 0.666; 95% CI: 0.501-0.885). The risk of under-five mortality was higher among four or more birth order children (AOR: 1.422; 95% CI: 1.246-1.624) compared with the first to third birth order children. The odds of under-five mortality decreased among children with a rich wealth index (AOR: 0.742; 95% CI: 0.592-0.93) compared to children with a poor wealth index. Interpretation & conclusions Analyses of under-five mortality among ST in India showed a significant association between different maternal, child, sociodemographic, and household factors. Grass-roots-level interventions such as promoting female education, addressing vast wealth differentials, and providing family planning services with a focus on reducing under-five mortality are essential in improving the survival of under-five children among the ST population in India.
