The aim of this study was to explore the association between long-term exposure to particulate matter with an aerodynamic diameter <2.5 μm (PM) and its components and severe obesity in children and adolescents.
Data for children and adolescents aged 9-18 in this cross-sectional study were obtained from the 2019 Chinese National Survey on Students' Constitution and Health (CNSSCH). Data for PM and its components were obtained from the Tracking Air Pollution in China (TAP) dataset and matched with information on these children. Logistic regression models were used to assess the risk of severe obesity associated with long-term exposure to PM and its components.
A total of 160,205 children were included in the analysis. Long-term exposure to PM may increase the odds of severe childhood obesity, with this effect being more pronounced in girls. Among boys, the component with the most significant impact on severe obesity was organic matter (OM). The impact of PM and its components on severe obesity was greater in children from low economic and low parental education level households. Children with unhealthy lifestyle habits have higher odds of severe obesity due to long-term exposure to PM and its components.
The findings of this research support the development of strategies aimed at addressing severe obesity in children, suggesting that adopting healthy lifestyle practices could mitigate the odds of severe obesity due to PM and its components. There is a need for an increased focus on children in economically underdeveloped areas and those with unhealthy lifestyle habits, particularly those in rural areas and those who do not engage in adequate physical activity or get enough sleep.
本研究旨在探讨长期暴露于空气动力学直径小于2.5微米的颗粒物（PM）及其成分与儿童和青少年严重肥胖之间的关联。
这项横断面研究中9至18岁儿童和青少年的数据来自2019年中国国家学生体质与健康调查（CNSSCH）。PM及其成分的数据来自中国空气污染追踪（TAP）数据集，并与这些儿童的信息相匹配。使用逻辑回归模型评估长期暴露于PM及其成分与严重肥胖相关的风险。
共有160,205名儿童纳入分析。长期暴露于PM可能会增加儿童严重肥胖的几率，这种影响在女孩中更为明显。在男孩中，对严重肥胖影响最显著的成分是有机物（OM）。PM及其成分对来自经济和父母教育水平较低家庭的儿童严重肥胖的影响更大。由于长期暴露于PM及其成分，生活方式不健康的儿童患严重肥胖的几率更高。
本研究结果支持制定旨在解决儿童严重肥胖问题的策略，表明采取健康的生活方式可以降低因PM及其成分导致严重肥胖的几率。需要更多关注经济欠发达地区以及生活方式不健康的儿童，特别是农村地区那些没有进行足够体育活动或睡眠不足的儿童。
