Does engagement in frequent physical activity improve diabetes mellitus among older adults in India? A propensity score matching approach

Diabetes is a major chronic condition and was identified as one of the four priority non-communicable diseases that the United Nations targeted because of its increasing disease burden. The present study aims to examine the impact of physical activity on improving diabetes mellitus among older adults in India.This study utilizes data from India's first nationally representative longitudinal ageing survey (2017-18). Descriptive along with bivariate analysis was used to present the preliminary results. Additionally, Propensity score matching (PSM) analysis was used.About 14% of older adults suffered from diabetes. Eighteen percent of older adults did frequent physical activity. The estimated average treatment effect on the treated (ATT) values in treated and control groups were 0.123 and 0.147, respectively, indicating that the prevalence of diabetes among older adults was reduced by 2.5% points because of frequent physical activity. The average treatment effect on the untreated (ATU) results indicates that among older adults who did not do frequent physical activity, if they did frequent physical activity, the prevalence of diabetes is likely to decrease by 2.2% points.Our findings show that frequent physical activity is associated with a lower risk of diabetes in older adults. The results underscore the need to develop strategies of promoting an active lifestyle by maintaining physical activity to combat the diabetes epidemic in the older population.
