Chronic Pain And Depressive Symptoms In Chinese Middle-Aged And Older Adults:A Follow Up Study


 Objective: This study aimed to analyze the effects of chronic pain on the occurrence of depressive symptoms in Chinese middle-aged and older adults, and to provide a scientific basis for reducing the incidence of depressive symptoms, improving the quality of life in middle-aged and older adults, and reducing the disease burden in the aging population.Methods: a prospective study was conducted to select adults aged 45 years or older from the longitudinal study of China Health and elderly care follow-up survey (Charls) (2015 and 2018). Pain was assessed according to the patient's self exposure, and depression was assessed using the Chinese version of the center for epidemiological research Depression Scale (CES-D). Univariate analysis and binary logistic regression model were used for analysis. Results: The 3-year cumulative incidence of depression in chronic pain patients was 52.4% and the annual incidence was 17.5% in the middle-aged and elderly Chinese population. Univariate analysis showed statistically significant differences in the incidence of depressive symptoms between the different genders, age, residence, education level, marriage, self perceived health status, nocturnal sleep time, number of social activities in the past month, smoking, alcohol consumption, impaired ADL and Medicare insurance coverage. This study, after controlling for demographic characteristics, health status and health behaviors, Different pain conditions remained statistically significant for depression in middle-aged and older adults. Compared with middle-aged and older adults without pain, both Unisomatic pain (OR = 1.388) and Multiple somatic pain (OR= 1.869) increased the risk of depression in the middle-aged and older populations. Conclusion: chronic pain is associated with the risk of depressive symptoms in middle-aged and elderly people, and the incidence of depression in middle-aged and elderly people in China is not optimistic.
