Association of Household Type and Fast-Food Consumption in Korean Adolescents.

Background: Due to changing household types and weakening of family functions, children have fewer opportunities to develop healthy lifestyle patterns from contact with family members compared to the past. In this paper, we evaluate the association between household type and adolescents' fast-food consumption, focusing on whether they were living with their parents or not, and determine their reasons for not living with their parents.

Methods: This cross-sectional study analyzed data from the Korea Youth Risk Behavior web-based survey between 2017 and 2020.
