中国中老年人身体活动水平与脑卒中发生的相关性:基于CHARLS数据OA北大核心CSTPCD

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 individ-uals 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 physi-cal 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 ac-tivity remained related factors of stroke. Conclusion Appropriate physical activity may reduce the risk of stroke.
