Body image refers to an individual's understanding of his own image，especially the appearance and the view of its sexual attraction.It has a certain influence on the mental health of the individual and affects the behavior of the individual.In this study，2460 residents，aged 18-70，in the city were investigated by sampling.The results of the survey showed that the residents of the city were more satisfied with their own body image.Among them，the marital status，age，and the daily average of the Internet had a significant impact on the body image.Meanwhile，the correlation analysis between body image and mental health showed that the two showed a significant correlation.After a simple linear regression analysis，it was found that the interpretation of body image on mental health can reach 18%.According to the survey results，it is suggested that we should further improve residents' mental health level by training residents' good media mastery，shaping multiple social aesthetic standards，and promoting residents' sense of self acceptance through the popularization of psychological knowledge.
