To explore the association between parental socioeconomic status (SES) and preschoolers' consumption of sugar-sweetened beverages (SSB). In June 2018, all preschoolers from 15 kindergartens were selected from the jurisdiction of Education Commission in Dongcheng District of Beijing by using an equal-proportion stratified cluster sampling method in the study. A self-designed questionnaire was used to investigate the parents of preschoolers to obtain the basic information of preschoolers and parents, the consumption situation of preschoolers' sugar-sweetened beverages and the perception of parents to SSB. A tatol of 3 217 preschoolers were finally included in the analysis. A generalized structural equation model was used to analyze the relationship between preschoolers' consumption of sugar-sweetened beverages and their parents' socioeconomic status and the mediating effect of their cognition of sugar-sweetened beverages. The size of mediating effect was estimated by using deviation correction non-parameter percentile Bootstrap method. The age of 3 217 preschoolers was (4.23±0.67) years, of which 52.6% (=1 692) were boys, and 77.62% (=2 497) were SSB consumers. Among the parents of 3 217 preschoolers, fathers and mothers accounted for 24.90% (=801) and 75.10% (=2 416), and the (, ) scores of SES were 66.7 (62.5, 69.5) and 69.5 (64.6, 71.4), respectively. The proportion of parents who took the initiative to learn about their children's consumption of SSB, lacked confidence in restricting preschooler's consumption of SSB and read nutrition labels before purchasing food was 74.08% (=2 383), 82.90% (=2 667) and 36.24% (=1 166), respectively. The generalized structural equation model showed that after adjusting for preschoolers' gender, age, body mass index (BMI) of preschoolers and their parents, preschoolers' consumption of SSB was negatively associated with their parents' SES score [path coefficient (95%):-4.69×10 (-6.56×10,-2.69×10) ]. The mediating effect of parents' perception of SSB consumption could explain 48.71% of the total effect [path coefficient (95%):-2.28×10 (-3.54×10, -1.10×10)]. The consumption of SSB in preschoolers is negatively associated with their parent's SES, and this relationship is partially mediated by parent's perception of SSB consumption.
探讨父母社会经济地位（SES）与学龄前儿童含糖饮料（SSB）消费之间的关联。2018年6月，本研究采用等比例分层整群抽样方法，从北京市东城区教育委员会管辖的15所幼儿园中选取所有学龄前儿童。使用自行设计的问卷对学龄前儿童的家长进行调查，以获取学龄前儿童及其家长的基本信息、学龄前儿童含糖饮料的消费情况以及家长对含糖饮料的认知。最终纳入分析的学龄前儿童共有3217名。采用广义结构方程模型分析学龄前儿童含糖饮料消费与其父母社会经济地位之间的关系以及他们对含糖饮料认知的中介作用。中介效应的大小采用偏差校正非参数百分位Bootstrap方法估计。3217名学龄前儿童的年龄为（4.23±0.67）岁，其中52.6%（=1692名）为男孩，77.62%（=2497名）为含糖饮料消费者。在3217名学龄前儿童的家长中，父亲和母亲分别占24.90%（=801名）和75.10%（=2416名），SES的（，）得分分别为66.7（62.5，69.5）和69.5（64.6，71.4）。主动了解孩子含糖饮料消费情况、对限制学龄前儿童含糖饮料消费缺乏信心以及在购买食品前阅读营养标签的家长比例分别为74.08%（=2383名）、82.90%（=2667名）和36.24%（=1166名）。广义结构方程模型显示，在调整学龄前儿童的性别、年龄、学龄前儿童及其父母的体重指数（BMI）后，学龄前儿童含糖饮料的消费与其父母的SES得分呈负相关[路径系数（95%）：-4.69×10（-6.56×10，-2.69×10）]。家长对含糖饮料消费认知的中介效应可解释总效应的48.71%[路径系数（95%）：-2.28×10（-3.54×10，-1.10×10）]。学龄前儿童含糖饮料的消费与其父母的SES呈负相关，且这种关系部分由家长对含糖饮料消费的认知介导。
