中国中老年人社交隔离的流行情况及相关因素OA

Objective To explore the current prevalence,cumulative incidence,distribution charac-teristics,and correlates of social isolation among middle-aged and older adults aged 45 years and older in Chi-na.Methods This study utilized data from the China Health and Retirement Longitudinal Study.Cross-sectional studies with stratified analysis were conducted to investigate the prevalence of social isolation and its age,gen-der,and regional differences in 2018 and 2020.A cohort study and binary logistic regression models were em-ployed to analyze the cumulative incidence of social isolation and its correlates from 2018 to 2020.Multiple impu-tation based on chained equations and sensitivity analyses based on complete-case data were employed to ensure the reliability of the analysis.Results The weighted prevalence of social isolation among middle-aged and older adults was 16.48%(95%CI=15.67%-17.32%)in 2018 and 18.84%(95%CI=17.93%-19.74%)in 2020.Weighted stratified analyses indicated that the prevalence of social isolation was higher among older adults of advanced ages,rural residents,and females(all P<0.001).The weighted cumulative incidence of social isolation during 2018-2020 was 9.24%(95%CI=8.47%-10.02%).The analysis revealed that 34.02%(95%CI=32.85%-35.19%)of middle-aged and older adults exhibited depressive symptoms.Depressive symptoms(OR=1.38,95%CI=1.07-1.78,P=0.013)were associated with an elevated risk of social isolation.Conclusions The study reveals the epidemiology of social isolation among middle-aged and older adults in China,identifying ad-vanced age,female gender,rural residence,and depressive symptoms as key correlates.These findings empha-size the need for early health management strategies to address social isolation in these high-risk populations.
