【摘要】：目的探讨学校周边快餐店数目与小学生肥胖的关联,为制定儿童肥胖的干预措施提供理论依据。方法采用整群随机抽样方法,选取北京市1个城区10所小学三~五年级学生共822名作为研究对象,进行身高、体重测量。使用百度地图检索学校周边半径800 m范围内快餐店数目。问卷调查学生年龄、性别、饮食行为、身体活动情况、视屏行为等肥胖相关的个体因素,以及父母的身高、体重和母亲受教育水平等家庭因素。采用两水平Logistic回归模型,分析学校周边快餐店数目与小学生肥胖的关联。结果 10所小学周边快餐店数目为(4.20±2.74)个/所。小学生肥胖率为8.64%,其中男生为12.50%,女生为4.83%,差异有统计学意义(χ~2=15.315,P0.01)。在不考虑肥胖相关的其他因素时,学校周边快餐店数目多是学生肥胖的危险因素(OR=1.092,95%CI=1.001~1.190);在调整个体因素和家庭因素后,学校周边快餐店数目多仍是学生肥胖的危险因素(OR=1.138,95%CI=1.030~1.258)。结论学校周边快餐店数目多是学生肥胖的危险因素,且独立于个体和家庭因素对学生肥胖产生影响。
[Abstract]:Objective to explore the relationship between the number of fast food restaurants and the obesity of primary school students, and to provide theoretical basis for the intervention measures of childhood obesity. Methods A cluster random sampling method was used to measure the height and weight of 822 students of grade 3 ~ 5 in 10 primary schools in one urban area of Beijing. Use Baidu map to retrieve the number of fast food restaurants within a radius of 800 m around the school. The questionnaire investigated the individual factors related to obesity, such as age, sex, dietary behavior, physical activity and video behavior, as well as family factors such as parents' height, weight and mother's education level. A two-level Logistic regression model was used to analyze the relationship between the number of fast food restaurants around the school and the obesity of primary school students. Results the number of fast food restaurants around 10 primary schools was (4.20 卤2.74). The obesity rate of primary school students was 8.64, among which 12.50 for boys and 4.83 for girls, the difference was statistically significant (蠂 ~ 2, 15.315, P0.01). When other factors related to obesity are not considered, the number of fast food restaurants around the school is the risk factor of obesity for students (OR=1.092,95%CI=1.001~1.190). After adjusting for individual and family factors, the high number of fast food restaurants around the school is still the risk factor of obesity (OR=1.138,95%CI=1.030~1.258). Conclusion the number of fast food restaurants around the school is a risk factor for students' obesity and independent of individual and family factors.
