摘要基于中国健康与营养调查（CHNS）的开放数据，以完成2011和2015年两轮调查的249名儿童青少年和249名家长为研究对象。根据儿童青少年快餐消费情况，将其分为快餐消费组和未消费组。采用logistic回归模型分析儿童青少年观看食品电视广告与快餐消费的关系。调整相关因素后结果显示，儿童青少年要求家长购买电视广告中食品的频率（ OR=3.122， P=0.001）、家长给孩子购买电视广告中食品的频率（ OR=4.717， P=0.036）、儿童青少年自己购买电视广告中食品的频率（ OR=3.728， P=0.041）、儿童青少年对电视广告中食品的喜爱程度（ OR=2.946， P=0.044）、家长报告的儿童青少年要求家长购买电视广告中食品的频率（ OR=3.113， P=0.002）与儿童青少年快餐消费有关联。

abstractsBased 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.
