Overweight/obesity and depressed mood in Chinese adults: A stratified test

This study investigated the relationship between overweight/obesity and depressed mood in Chinese adults, examining the influence of factors such as age, gender, and place of residence. We conducted statistical tests on data from 10,833 participants of the 2018 Chinese General Social Survey (CGSS), using multiple linear regression analysis and stratified linear regression analysis. The results showed a significant and negative association between overweight/obesity and depressed mood, in which those who were overweight/obese had fewer instances of depressed mood. We found the negative correlation between overweight/obesity and depressed mood to be more significant in the Fortunate Generation cohort group and the urban group, and there was also a significant and negative association between overweight/obesity and depressed mood for men. These findings clarify the association between overweight/obesity and depressed mood as well as provide guidance for the development of relevant policies that target prevention and control.
