Abstract:

Objective To investigate the association between levels of physical activity and incidence of stroke among middle-aged and older individuals in China.

Methods The self-reported data of 19 395 respondents from the China Health and Retirement Longitudinal Study (CHARLS) 2020 dataset were analyzed.

Results There were 1 368 cases of stroke (7.05%). The participants aged ≥ 65 years (OR = 1.049, 95%CI 1.043 to 1.055, P < 0.001), living separately from their spouse (OR = 2.004, 95%CI 1.091 to 3.683, P = 0.025) and widowed (OR = 1.669, 95%CI 1.452 to 1.919, P < 0.001) were in more risk of stroke. Compared to participants accepting education of primary school, individuals accepting education of middle school (OR = 0.766, 95%CI 0.664 to 0.883, P < 0.001), high school and technical school (OR = 0.804, 95%CI 0.665 to 0.972, P = 0.024), and higher school or above (OR = 0.568, 95%CI 0.361 to 0.894, P = 0.015) were in less risk of stroke; as well as the individuals with moderate-intensity physical activity (OR = 0.691, 95%CI 0.598 to 0.799, P < 0.001) and high-intensity physical activity (OR = 0.417, 95%CI 0.364 to 0.478, P < 0.001) compared with those with low-intensity physical activity. After adjusting for marital status and education levels, aged ≥ 65 years (OR = 2.398, 95%CI 2.139 to 2.668, P < 0.001), females (OR = 0.834, 95%CI 0.746 to 0.933, P =0.001), moderate-intensity (OR = 0.755, 95%CI 0.652 to 0.874, P < 0.001) and high-intensity (OR = 0.498, 95%CI 0.433 to 0.572, P < 0.001) physical activity remained related factors of stroke.

Conclusion Appropriate physical activity may reduce the risk of stroke.
