Childhood overweight and obesity (OWO) has risen dramatically in both developed and developing countries over the past few decades, creating a huge burden of disease. Ambient air pollution and emotional and behavioral problems are important influencing factors of OWO in preschoolers, but few studies have evaluated the impact of air pollution and emotional and behavioral problems on OWO of preschoolers in rural areas and their potential interactions. This study selected 3802 preschool children from 26 kindergartens in 4 rural areas of Anhui Province for a cross-sectional study. A total of 3636 individuals were included in the final analysis. In this study, outdoor air pollutants (PM and O) were derived from the China Air Pollution Tracking (TAP) data set, matching preschoolers' external air pollution exposure according to their kindergarten address codes to neighborhoods or administrative villages. OWO were assessed based on WHO Child Growth and Development Standards. Generalized linear model (GLM) and interplot model were used to evaluate the separate effects and potential interactions of air pollutants and emotional and behavioral problems on preschoolers' OWO. In the separate analysis, we found a significant positive association between air pollution and emotional and behavioral problems and OWO among preschoolers. In the interaction analysis, air pollution could enhance the positive effect of emotional and behavioral problems on OWO in preschoolers. In addition, the effect of air pollution and emotional and behavioral problems on overweight and obesity was stronger in preschoolers aged 5 to 6 years. Finally, we also found a stronger positive association between emotional and behavioral problems among girls, macrosomia, non-left-behind children, and preschoolers without eating problems. This study provided a scientific basis for the control of air pollution and overweight and obesity among preschool children in Anhui Province.
在过去几十年中，儿童超重和肥胖（OWO）在发达国家和发展中国家均急剧上升，造成了巨大的疾病负担。环境空气污染以及情绪和行为问题是学龄前儿童OWO的重要影响因素，但很少有研究评估空气污染与情绪和行为问题对农村地区学龄前儿童OWO的影响及其潜在相互作用。本研究选取了安徽省4个农村地区26所幼儿园的3802名学龄前儿童进行横断面研究。最终分析纳入3636人。本研究中，室外空气污染物（PM和O）来源于中国空气污染跟踪（TAP）数据集，根据学龄前儿童所在幼儿园地址编码将其外部空气污染暴露情况与社区或行政村进行匹配。OWO根据世界卫生组织儿童生长发育标准进行评估。采用广义线性模型（GLM）和交互作用模型评估空气污染物与情绪和行为问题对学龄前儿童OWO的单独影响及潜在相互作用。在单独分析中，我们发现空气污染、情绪和行为问题与学龄前儿童OWO之间存在显著正相关。在交互作用分析中，空气污染可增强情绪和行为问题对学龄前儿童OWO的正向影响。此外，空气污染和情绪及行为问题对5至6岁学龄前儿童超重和肥胖的影响更强。最后，我们还发现女孩、巨大儿、非留守儿童以及没有饮食问题的学龄前儿童的情绪和行为问题之间存在更强的正相关。本研究为安徽省学龄前儿童空气污染及超重和肥胖的防控提供了科学依据。
