Fast food and anxiety symptoms of Chinese multi-ethnic adolescents: The moderating role of regulatory emotional self-efficacy.

Background: Although previous studies demonstrated an association between fast food intake and anxiety symptoms in adolescents, this relationship has not been studied in Chinese multi-ethnic adolescents. The purpose of this study is to investigate the aforementioned association and the potential moderating effect of regulatory emotional self-efficacy (RESE) among Chinese multi-ethnic adolescents.

Methods: A cluster random sampling of 8500 middle school students from 11 counties in Yunnan province was conducted.
