社区建成环境与儿童青少年含糖饮料摄入的关联性研究

目的 描述儿童青少年含糖饮料（sugar-sweetened beverages，SSBs）摄入频率，探讨社区建成环境与儿童青少年SSBs摄入间的相关性。方法 于2019年4—5月采用整群随机抽样的方式抽取深圳市宝安区30 188名在校学生为研究对象，以问卷形式调查社区建成环境要素和儿童青少年SSBs摄入频率，采用χ2检验比较不同特征的儿童青少年SSBs摄入频率，多元logistic回归用于分析社区建成环境要素与SSBs摄入频率间的关联性。结果 儿童青少年低频率、中频率和高频率SSBs摄入占比分别为26.8%、51.8%和21.5%。与居住楼层≥7层相比，居住楼层≤3层儿童青少年可增加SSBs的摄入（OR＝1.13，95%CI:1.04～1.24）；居住地和主干道间的距离与儿童青少年SSBs摄入频率呈负向关联（OR＝1.24，95%CI:.10～1.39）；居住地周边饭店数量与儿童青少年SSBs摄入频率呈正向关联（OR＝1.81，95%CI:1.63～2.02）。结论 儿童青少年SSBs摄入频率与社区建成环境因素相关，居住楼层越低、居住地和主干道间的距离越近、居住地周边饭店数量越多增加儿童青少年SSBs的摄入。

Relationship between built environment in community and sugar-sweetened beverages intake among children and adolescents

Objective To describe the frequency of sugar-sweetened beverages (SSBs) intake of children and adolescents, and to determine the relationship between built environment in community and SSBs intake among children and adolescents. Methods A large cross-section was conducted in Baoan District, Shenzhen, from April to June in 2019. A total of 30 188 students were included by the way of cluster random sampling. The frequency of SSBs intake and built environment in community were investigated by questionnaire. The chi-square test was used to compare the frequency of different characteristics of children and adolescents. Multiple logistic regression models were used to analyze the relationship between built environment in community and SSBs intake. Results The low frequency, medium frequency, high frequency of SSBs respectively accounted for 26.8%, 51.8% and 21.5%. Comparing with children and adolescents living on the 7th floor or above, those who lived on the 3th floor or below might increase the SSBs intake (OR=1.13, 95%CI: 1.04-1.24); the closer distance between residence and main road, the higher the frequency of children and adolescents intaking SSBs (OR=1.24, 95%CI: 1.10-1.39); the more restaurants around the residence of children and adolescents who also took in more SSBs (OR=1.81, 95%CI: 1.63-2.02). Conclusion The frequency of SSBs intake among children and adolescents is correlated with the built environment in community. The lower residential floor is, the closer distance between residence and main road is and the more restaurants around the residence are, the more SSBs those would intake.
