Abstract Objective To explore the depressive symptoms and influencing factors of the elderly in China. Methods The study used data from the 8th round of the Chinese longitudinal healthy longevity survey (CLHLS) conducted in 2017—2018. CLHLS adopted multi-stage stratified sampling method. After screening the data according to inclusion and exclusion criteria, 6 318 elderly people were finally included as study subjects. The study was conducted from five dimensions: dem- ographic characteristics, social support, lifestyle, health status, and economic status. Logistic regression was used to analyze the influencing factors of depressive symptoms in elderly people in China. Results There were statistically significant differences in gender, body mass index(BMI), education level, smoking, drinking, exercise, marital status, residence status, annual income, health status, and place of residence among elderly people with different depressive symptoms (P < 0.05). Logistic regression analysis showed that BMI<18.5 kg/m2 (OR=1.39, 95%CI: [1.15, 1.69]), widowed (OR=1.33, 95%CI: [1.06, 1.65]), and living alone (OR=1.35, 95%CI: [1.10, 1.66]) were risk factors for depressive symptoms in elderly people (P<0.05). Exercise (OR=0.65, 95%CI: [0.53, 0.80]), good health (OR=0.22, 95%CI: 0.18, 0.27]), and affluence (OR=0.79, 95%CI: [0.64, 0.98]) were the protective factors (P<0.05). Conclusion The likelihood of depressive symptoms in elderly people who are thin, widowed, and living alone is higher than that in elderly people who are of normal weight, married and living with their spouse, and living with their family. Exercise, good health, and affluence are less likely to cause depressive symptoms in elderly people than those who do not exercise, have poor health, and are very poor.
