摘　　要：目的分析老年人个体社会资本对健康自评的影响、探讨抑郁及睡眠时长的调节作用。方法于“中国健康与养老追踪调查”官网下载2018年的CHARLS调查数据,筛选有效被试2747人,利用Pearson积差相关法检验个体社会资本、健康自评、抑郁以及睡眠时长变量之间的相关性;并利用Process v4.2插件中的Model7检验抑郁的中介作用和睡眠时长的调节作用。结果不同文化程度老年人健康自评(F=3.506,P<0.01)、个体社会资本(F=6.865,P<0.01)、抑郁(F=7.087,P<0.001)的得分比较,差异有统计学意义(P<0.01);老年人个体社会资本(r=0.120,P<0.01)、抑郁(r=-0.085,P<0.01)与健康自评有显著相关性,个体社会资本与抑郁呈显著负相关(r=-0.064,P<0.01)、睡眠时长与健康自评呈显著正相关(r=0.143,P<0.01);老年人个体社会资本对健康自评的预测作用显著(β=0.120,t=6.356,P<0.001),将抑郁做中介变量后、老年人个体社会资本对健康自评的预测作用依然显著(β=0.115,t=6.100,P<0.01,95%CI为0.001~0.007);睡眠时长与个体社会资本的交互项调节了个体社会资本对抑郁的预测路径(β=-0.139,P<0.05,95%CI为-0.266~0.112)。结论老年人个体社会资本通过抑郁对健康自评产生影响,睡眠时长在其中起调节作用。Objective To analyze the influence of individual social capital on self-assessment of health and explore the regulation of depression and sleep duration.Method The 2018 CHARLS survey data was downloaded from the official website of the"China Health and Pension Tracking Survey",and 2747 valid subjects were screened.The correlations between individual social capital,self-assessment health,depression,and sleep duration variables were examined by the correlation method of Pearson product-difference.Mediating effects of depression and modulation of sleep length were tested by Model7 in the Process v4.2 plugin.Result The self-assessment of health(F=3.506,P<0.01),individual social capital(F=6.865,P<0.01)and depression(F=7.087,P<0.001)scores of the elderly with different educational levels were compared,and the difference was statistically significant(P<0.01).The individual social capital of the elderly(r=0.120,P<0.01)and depression(r=-0.085,P<0.01)were significantly associated with self-assessment of health.Individual social capital showed a significant and negative correlation with depression(r=-0.064,P<0.01),and sleep length was significantly and positively associated with self-assessment of health(r=0.143,P<0.01).Individual social capital of the elderly had a significant prediction effect on self-assessment of health(β=0.120,t=6.356,P<0.001),and the prediction effect of individual social capital on self-assessment of health remained significant after using depression as the intermediary variable.After using depression as the intermediary variable,the predictive effect of individual social capital in the elderly on the self-assessment of health was still significant(β=0.115,t=6.100,P<0.01,95%CI was 0.001-0.007).The interaction term of sleep duration with individual social capital regulated the prediction path of individual social capital on depression(β=-0.139,P<0.05,95%CI was-0.266-0.112).Conclusion Individual social capital of the elderly affects health self-assessment through depression,and sleep duration plays
