Abstract: Objective To analyze the current status and influencing factors of the intake of sugar-sweetened beverages (SSB), so as to provide scientific basis for effectively reducing SSB intake in pupils and promoting children′s health. Methods From September to November 2021, a total of 919 students aged 9-13 years in grade four to grade six were selected to fill out the questionnaire from four primary schools in Luzhou by random cluster sampling. SSB intake status was descriptively analyzed. Kruskal-Wallis H test, and ordinal multiclass Logistic regression analysis were used to analyze the influencing factors of SSB intake. Results Among 919 pupils surveyed, 67.9% reported that they consumed less than 1 bottle of sugar-sweetened beverages per week, 27.3% for 1-2 bottles per week, and 4.8% for ≥3 bottles per week. Multivariate analysis showed that the high frequency of friends around drinking SSB (always:OR=3.00, 95%CI:1.21-7.47), buying SSB at school (always:OR=9.46, 95%CI:2.71-32.97), parents offering SSB (always:OR=6.32, 95%CI:1.60-24.98), buying SSB at home (always:OR=18.23, 95%CI:5.92-56.21) and average daily TV/video time (≥2 hours:OR=2.14, 95%CI:1.35-3.39) were positively correlated with SSB intake. Conclusions The intake level of SSB among pupils in Luzhou is relatively high, with 32.1% of primary school students consuming more than 1 bottle (230ml) of SSB per week. It is mainly affected by friends around, the availability of SSB at school and home, and the average daily TV/video time. The available access to sugary drinks for elementary school students should be reduced, peer education should be emphasized, and a supportive environment should be actively constructed to foster good diatary habits and promote healthy growth of children.

摘要： 目的 了解泸州市小学生含糖饮料摄入情况及其影响因素,为有效减少小学生含糖饮料的摄入,促进儿童健康提供科学依据。方法 采用整体随机抽样法,于2021年9—10月抽取泸州市4所小学4～6年级919名9～13岁儿童作为研究对象,进行问卷调查,对含糖饮料的摄入现状进行描述分析,采用Kruskal-Wallis H秩和检验、有序多分类Logistic回归分析进行统计学处理。结果 在919名学生中,有67.9%的小学生每周含糖饮料摄入为＜1瓶,27.3%为1～2瓶,4.8%为≥3瓶。多因素分析结果显示,周围朋友喝含糖饮料频率(总是:OR=3.00,95%CI:1.21～7.47),在学校购买含糖饮料频率(总是:OR=9.46,95%CI:2.71～32.97),父母提供含糖饮料频率(总是:OR=6.32,95%CI:1.60～24.98),在家购买含糖饮料频率(总是:OR=18.23,95%CI:5.92～56.21)及日均电视/视频时长过长(≥2h:OR=2.14,95%CI:1.35～3.39)均和含糖饮料摄入量呈正相关。结论 泸州市小学生含糖饮料摄入水平较高,有32.1%的小学生每周含糖饮料摄入超过1瓶(230ml),主要受到周围朋友、学校和家中含糖饮料可获得性及日均电视/视频时长的影响,应减少小学生含糖饮料的可获得途径,重视同伴教育,积极构建支持性环境,培养其良好饮食习惯,促进儿童健康成长。
