Objective: This research aimed to learn how various socio-demographic factors are associated with nutritional status among Indian Scheduled Tribe reproductive women. Moreover, to understand the spatial variation of Nutritional status among Scheduled tribe women in the current scenario.Methods: The study shows the distribution of underweight, normal, overweight and obese Scheduled Tribe women in India from the National Family Health Survey (NFHS-5), including 1,66,172 women from Schedule tribes reproductive age group. The multinomial logistic regression model was used to analyse how different background factors are associated with BMI.Results: The study observed that among tribal women, 17.4% are underweight, 13.2% overweight, and 2.97% obese. Approximately one-third of the tribal women in the reproductive age group have normal BMI. The age group 15–24 has the highest percentage of underweight, whereas the age group 35 and beyond has the highest prevalence of overweight and obesity.Most of the socio-demographic factors are associated with nutritional level among Scheduled tribe women; The wealth quantile shows the maximum impact on nutritional health among Scheduled tribe women.Conclusion: Scheduled Tribe people are one of the most vulnerable groups in India. As a result, this population is at high risk in practically every health parameter. They continue to depend heavily on subsistence farming for income and survival. The findings provide further evidence that the religion, place of residence, wealth status, age group, education, marital status, parity and family size are some important determinants that are directly associated with nutritional status among tribal women in India.
