The problem of overweight/obesity often coexists with the burden of undernutrition in most low- and middle-income countries. BMI change in India incorporating the most recent trends has been under-researched. This repeated cross-sectional study of 1,477,885 adults in India analyzed the prevalence of different categories of BMI among adults (age 20�) in 4 rounds of National Family Health Surveys (1998�99, 2005�06, 2015�16, and 2019�21) for 36 states/UTs.
