To explore the relationship between physical activity and cardiometabolic multimorbidity (CMM) among older adults in the community.
Using data from the 2020 China Health and Retirement Longitudinal Study(CHARLS), 9 076 older participants were included. Propensity score matching was employed to control for confounding factors in analyzing the association between physical activity and the number of cardiometabolic diseases. Multivariable logistic regression and restricted cubic spline models were used to evaluate the relationship between physical activity level (PAL) and CMM risk.
Propensity score matching showed that sufficient physical activity was associated with an average reduction of 0.20 in the number of cardiometabolic diseases (ATT: -0.187~-0.225). Logistic regression indicated that a PAL ≥1 800 MET-min/week was significantly associated with lower CMM risk (1 800<PAL≤3 000: OR=0.814, 95% CI: 0.682-0.972; PAL≥3 000: OR=0.647, 95% CI: 0.572-0.732). The restricted cubic spline model revealed a nonlinear dose-response relationship between PAL and CMM risk (P for nonlinear <0.05). The risk of CMM decreased notably at a PAL around 3 800 MET min/week, and the association plateaued when PAL exceeded 8 000 MET min/week.
Physical activity is associated with a reduction in the number of cardiometabolic diseases. Maintaining an adequately high level of physical activity may have a positive effect on preventing CMM in older adults.
