Childhood overweight and obesity is a global problem. 38 million children under five years old were reported as being overweight/obese in 2019. However, current evidence regarding the effects of air pollution on children weight status remains scarce and inconsistent. This study aimed to determine the association between air pollutants and the weight status of children and adolescents. Four databases were searched up to August 9, 2023. Adjusted merged odds ratios (ORs), regression coefficients (β), and their 95 % confidence intervals (95 % CIs) were calculated and pooled. A total of 27 studies were included. The results showed that air pollutants had adverse effects on the body weight of children and adolescents. Exposure to PM, PM, PM, and PM were associated with increased risk of overweight/obesity, with pooled ORs (95 % CI) of 1.23 (1.09, 1.40), 1.18 (1.10, 1.28), 1.04 (1.03, 1.05) and 1.11 (1.06, 1.17) per 10 μg/m increment, respectively. Individuals with higher exposure levels to NO, O, SO and CO (per 10 μg/m increment) were associated with 12 %, 6 %, 28 % and 1 % increased odds of being overweight/obese, respectively. With respect to the level of body mass index, the pooled β (95 % CIs) for each 10 μg/m increase in PM, PM, PM, and NO exposure were 0.15 (0.12, 0.18), 0.11 (0.06, 0.16), 0.07 (0.03, 0.10), and 0.03 (0.01, 0.04), respectively. PM has relatively strong adverse effects on body weight status. The subgroup analysis revealed a significantly increase in the risk of overweight/obesity when the concentrations of PM, PM, and NO exceeded 35 μg/m, 50 μg/m, and 40 μg/m, respectively. Exposure to PM, PM and NO increased the risk of overweight/obesity, especially in Asia. This study provides evidence of the association between air pollution and being overweight/obese in children and adolescents.
儿童超重和肥胖是一个全球性问题。据报道，2019 年有 3800 万五岁以下儿童超重/肥胖。然而，目前关于空气污染对儿童体重状况影响的证据仍然很少且不一致。本研究旨在确定空气污染物与儿童和青少年体重状况之间的关系。截至 2023 年 8 月 9 日，对四个数据库进行了搜索。计算并汇总了调整后的合并优势比（OR）、回归系数（β）及其 95%置信区间（95%CI）。共纳入 27 项研究。结果表明，空气污染物对儿童和青少年的体重有不良影响。暴露于 PM、PM、PM 和 PM 与超重/肥胖的风险增加有关，每增加 10μg/m，汇总的 OR（95%CI）分别为 1.23（1.09，1.40）、1.18（1.10，1.28）、1.04（1.03，1.05）和 1.11（1.06，1.17）。NO、O、SO 和 CO（每 10μg/m 增加）的个体暴露水平较高，超重/肥胖的几率分别增加 12%、6%、28%和 1%。关于体重指数水平，PM、PM、PM 和 NO 暴露每增加 10μg/m，汇总的β（95%CI）分别为 0.15（0.12，0.18）、0.11（0.06，0.16）、0.07（0.03，0.10）和 0.03（0.01，0.04）。PM 对体重状况有相对较强的不良影响。亚组分析显示，当 PM、PM 和 NO 浓度分别超过 35μg/m、50μg/m 和 40μg/m 时，超重/肥胖的风险显著增加。暴露于 PM、PM 和 NO 会增加超重/肥胖的风险，尤其是在亚洲。本研究提供了空气污染与儿童和青少年超重/肥胖之间关联的证据。
