我国四城市儿童少年食用西式快餐频度和肥胖率关系的分析

目的:分析我国城市儿童少年食用西式快餐频度与肥胖率之间的关系,为制定肥胖干预措施提供理论依据。方法:采用分层整群随机抽样的方法,从广州、上海、济南、哈尔滨等4城市的城区及近郊区抽取4～16岁的儿童少年及家长进行问卷调查,共调查9356个孩子-家长对,同时收集儿童少年的身高、体重资料。结果:4城市儿童少年中每月食用西式快餐0次、≤1次和>1次的比例分别为20.3%、62.5%和17.2%,肥胖率依次为10.5%、12.0%和13.4%。每月食用西式快餐>1次儿童少年的肥胖率显著高于不吃西式快餐的儿童少年,其肥胖的危险性是不吃西式快餐儿童少年的1.282倍。结论:经常食用西式快餐是影响儿童肥胖的一个独立环境因素,它使经常食用西式快餐的儿童少年发生肥胖的危险性大于不吃西式快餐的儿童少年

RELATION BETWEEN THE FREQUENCY OF FAST FOOD CONSUMPTION AND OBESITY PREVALENCE AMONG CHILDREN AND ADOLESCENTS LIVING IN FOUR CITIES OF CHINA

Objective: To study the relation between the frequency of fast food consumption and obesity prevalence among children living in 4 cities of China, and to provide scientific evidence for developing intervention strategies for the prevention of childhood obesity. Methods: Stratified multistage cluster random sampling method was used for recruiting subjects. 9 356 children-parent pairs were investigated using questionnaires survey for collecting information on fast food consumption. Body weight and height were measured in the clinic of the investigated kindergartens or schools by trained interviewers following the standardized procedure. Results: The frequency of eating fast food 0 times ≤1 times and>1 times monthly of children was 20.3%, 62.5% and 17.2%, respectively. The obesity prevalence of children who consumed fast food 0 times, ≤1 times and >1 times monthly was 10.5%、12.0% and 13.4%, respectively. The obesity prevalence of children who had fast food more than 1 times each month was significant high than those who did not have fast food. Conclusions: Fast food consumption contributes to an increase risk of obesity, fast food frequency is an independent factor related to pediatric obesity.
