Interactive Effect of Lifestyle, Sleep Quality and Depressive Symptoms: A Questionnaire Study of Retired Workers in A Medium-sized City of Northeastern China

摘要

Lifestyle is an important determinant factor for mental diseases. This cross-sectional study aimed to examine the independent and interactive association between lifestyle and sleep quality with depressive symptoms in Chinese retired workers. One thousand two hundred and sixty-eight retired workers (aged 60 - 94 yrs) in China were recruited in this study. The outcomes were self-reported depressive symptoms, sleep quality, lifestyle and demographic variables. The detection rate of depressive symptoms and sleep disorder was 30.8% and 38.5%. Unhealthy lifestyle was significantly associated with depressive symptoms (OR = 9.801, 95% CI: 6.357 - 15.112). Sleep disorder was significantly positively correlated with depressive symptoms (OR = 1.280, 95% CI: 1.003 - 1.632). Unhealthy lifestyle and sleep disorder were independently and interactively associated with increased risks of depressive symptoms. These findings suggest that unhealthy lifestyle and sleep disorder are potentially suffering from depressive symptoms in Chinese retired workers. Intervention programs should enhance lifestyle and improve sleep quality.
