四省(市)八地区中学生含糖饮料消费行为的影响因素研究

Factors affecting the consumption of sugar-sweetened beverages among middle school students in eight counties of four provinces (municipality) in China

目的研究四省(市)八地区中学生含糖饮料消费行为的影响因素。方法选取四省(市)八地区儿童健康队列中的中学生3 469人.通过问卷调查收集儿童社会人口学、家庭情况、学校饮料可获得性、个人行为等,并收集过去1周含糖饮料消费的频次。计算总体含糖饮料消费次数。利用多因素Logistic回归模型,分析高含糖饮料消费行为(》1次/d)的影响因素。结果四省(市)八地区中学生高含糖饮料消费率为11.18%,总体消费次数的中位数为0.21次/d。促进高含糖饮料消费的因素包括高年级、来自农村、男性、校内体育锻炼多(M4d/周)、有零食习惯(纣次/d)、过去1周在外就餐、过去1周吃过西式快餐。高含糖饮料消费的影响因素在男性和女性中有所不同,校内体育锻炼仅是女性学生高含糖饮料消费的影响因素(P<0.01),高年级和在外就餐仅是男性学生高含糖饮料消费的影响因素(P<0.05)。结论中学生含糖饮料消费行为的影响因素包括年级、城乡、校内体育锻炼、零食习惯、在外就餐及快餐消费情况,而且具有性别差异,针对这些因素进行干预将有助于控制中学生含糖饮料的消费。

Objective To explore the factors related to the consumption of sugar-sweetened beverages (SSB) among middle school students in four provinces (municipality) inChina. Methods A total of 3 469 middle school students were recruited from the Children health cohort in eight counties within the four provinces (municipality). We collected information regarding demography, lifestyle, and family and school s让uation as well as the consumption frequency of SSB in the previous week. High SSB consumption was defined as "positive" if the frequency was once a day or more. Mean consumption time was calculated, and then logistic regressions were performed to explore the factors influencing SSB consumption. Results Prevalence of high SSB consumption was 11.18% among the subjects of the eight counties, and the consumption frequency of SSB was 0.21 times per day. Multivariate logistic regression analysis revealed that the following factors were associated with high consumption of SSB: higher grade, rural region, male gender;physical exercise, habit of eating snacks, eating out, and fast-food consumption (P<0.01). Factors influencing high SSB consumption were not completely equal between genders: physical exercise at school was associated with high SSB consumption only in female students (PvO.Ol), while higher grade and eating out in the past week were associated w让h high SSB consumption only in male students (P<0.05). Conclusion Factors associated with high SSB consumption among middle school students included grade, region, physical exercise at school, snack consumption, eating out, and fast-food consumption. These factors differed between genders. Intervention programs addressing these factors may be beneficial in reducing SSB consumption in middle school students.
