A total of 642 valid questionnaires were obtained. Linear regression analysis was used to analyze the influencing factors, and the mediating effect test was conducted by stepwise regression analysis. Results:The influencing factors of depression in the retired employees were physical exercise (β=-0.948, P<0.01), entertainment (β=-1.423, P<0.01), whether to suffer from chronic diseases (β=2.579, P<0.01), family income (β=-0.557, P<0.05), whether to insist on work (β=-1.673, P<0.05), and whether to live alone (β=2.097, P<0.01).The influencing factors of anxiety were physical exercise (β=-0.711, P<0.05), entertainment (β=-1.380, P<0.01), whether to suffer from chronic diseases (β=1.204, P<0.05), and whether to live alone (β=1.639, P<0.05).In the elderly, living alone status and social participation quality were input in the linear regression as the independent variables,and the results showed that the effects of living alone status on depression and anxiety had no the significant differences (β=0.837, P=0.218; β=0.837, P=0.218), and social participation quality played a full mediating role between living alone status and depression and anxiety.
