To investigate the relationship between unhealthy weight loss behaviors and depressive symptoms among adolescents in Chongqing. From October to November in 2019, 4 urban combined junior and senior high school and 4 rural combined junior and senior high school in Chongqing were selected by stratified cluster sampling method, and the unhealthy weight loss behavior questionnaire and the center for epidemiological studies depression scale(CES-D scale) were used to investigate the weight loss behavior and depression symptoms of junior one to senior three students. A total of 3969 subjects were enrolled, including 1479(37.26%) males and 2490(62.73%) females. Chi-square test was used to analyze the relationship between general demographic characteristics and depressive symptoms, and binary Logistic regression model was used to analyze the relationship between unhealthy weight loss behavior and depressive symptoms. Among the 3969 subjects, 2972(74.88%) reported unhealthy weight loss behaviors, and 1459(36.76%) had depressive symptoms. There were significant differences in depressive symptoms among adolescents with different gender(χ~2=34.83, P<0.01), school type(χ~(2 )=6.75, P<0.01), father's parenting style(χ~2=159.64, P<0.01), mother's parenting style(χ~2=160.10, P<0.01), family economic conditions(χ~2=63.88, P<0.01), learning pressure(χ~2=207.53, P<0.01), number of close friends(χ~2=177.52, P<0.01)and number of school health education classes(χ~2=31.60, P<0.01). Binary Logistic regression analysis showed that unhealthy weight loss behavior was a risk factor for depressive symptoms(OR=1.436, P<0.01), and unhealthy weight loss level was positively correlated with the prevalence of depressive symptoms(OR>0, P<0.01). There was a positive correlation between unhealthy weight loss behavior and depressive symptoms among adolescents in Chongqing.
