Objective To analyze the correlation between socioeconomic status(SES)and depressive symptom of middle-aged and elderly people,and provide the scientific evidence for the prevention of depression in middle-aged and elderly people.Methods A total of 9 739 cases who completed the Geriatric Depression Scale(GDS-15)survey in the third phase of baseline survey of Guangzhou Biobank Cohort(September 2006 to February 2008)were selected as the subjects.The data of demographic characteristics,SES and depression symptom were collected.The t test,x2 test,trend x2 test and multivariate logistic regression were used to analyze the data.The used software was SPSS 26.0.Results The mean age of subjects was(60.2±7.8)years old.The rate of positive depressive symptom was 14.5％.The multivariate logistic regression showed that after adjusting the gender,age,marriage,smoking,alcohol drinking,physical activity,diet habits,self-rated health,chronic disease comorbidity and support from relatives and friends,the SES of comprehensive score,educational level,job and family annul income correlated independently to depressive symptom,the risk of positive depressive symptom increase with decreased SES and educational level(Ptrend＜0.01).The high risk of positive depressive symptom in middle-aged and elderly people correlated to moderate SES(OR=1.47,95％CI:1.25-1.74),lower SES(OR=2.12,95％CI:1.81-2.50),junior middle school level(OR=1.22,95％CI:1.04-1.44),≤elementary school level(OR=1.43,95％CI:1.21-1.69),hand work and other jobs(OR=1.33,95％CI:1.11-1.59)and family annual income＜30 000 yuan(OR=1.45,95％CI:1.27-1.65).There was no interaction between educational level,annual household income or occupation and depressive symptom(P＞0.05).Conclusion Comprehensive score of SES is better associated with depressive symptom than its representative indicators.The prevention and control of depression in the middle-aged and elderly people should focus on those with lower SES.
