Abstract:
Objective To understand the changes in self-rated health among middle-aged and elderly individuals in China and the influencing factors,providing a reference for improving health and promoting healthy aging.Methods Using data from the China Health and Aged Care Tracking Survey(CHARLS)from 2011 to 2020,this study analyzed 3595 middle-aged and elderly individuals(≥45 years old)who participated in all five rounds of the survey from 2011 to 2020.Univariate analysis and multinomial logistic regression were employed to analyze the influencing factors of self-rated health changes.Results Among the 3 595 middle-aged and elderly individuals,26.54％reported an increase in self-rated health,28.40％reported a decrease,and 45.06％reported no change.The multinomial logistic regression results indicated that compared to those with unchanged self-rated health,individuals whose self-rated health declined were more likely to have an increased number of Activities of Daily Living(ADLs),a higher number of chronic diseases,not engaging in at least 10 minutes of light physical activity per week,and a decline in life satisfaction levels.The odds ratios for these factors were 1.415(OR=1.415,95％CI:1.181～1.694),1.479(OR=1.479,95％CI:1.225～1.785),1.454(OR=1.486,95％CI:1.172～1.804),and 1.263(OR=1.237,95％CI:1.043～1.530),respectively.In contrast,individuals whose self-rated health improved,compared to those with unchanged health,were more likely to report an increase in life satisfaction levels,while an increase in ADLs and chronic diseases negatively impacted self-rated health improvement.The odds ratios for these factors were 1.698(OR=1.698,95％CI:1.425～2.023),0.769(OR=0.769,95％CI:0.646～0.915),and 0.689(OR=0.689,95％CI:0.549～0.865),respectively.Conclusion From 2011 to 2020,the self-rated health of middle-aged and elderly individuals in China has slightly declined,with a focus on improving physical health status,increasing physical activity,and addressing mental health as key areas for enhancing self-rated health among the elderly in China.
