Abstract： Based on the open data of China Health and Nutrition Survey (CHNS), 249 children, adolescents and 249 heads of families who completed two rounds of surveys in 2011 and 2015 were selected in this study. According to the fast food consumption of children and adolescents, they were divided into fast food consumption group and non-fast food consumption group. Logistic regression model was used to analyze the relationship between children and adolescents watching Food TV advertising and fast food consumption. After adjusting relevant factors, the results showed that children and adolescents requiring their parents to buy food in TV advertisements ( OR=3.122, P=0.001), parents buying food for their children in TV advertisements ( OR=4.717, P=0.036), children and adolescents buying food in TV advertisements themselves ( OR=3.728, P=0.041), children and adolescents′ preference for food in TV advertisements ( OR=2.946, P=0.044) and the frequency of children and adolescents reported by their parents asking their parents to buy food in TV advertisements ( OR=3.113, P=0.002) were associated with children and adolescents′ fast food consumption.
