Abstract

Despite extensive research on the detrimental effects of air pollution on health, limited focus has been directed toward the impact of air pollution on child growth. Utilizing comprehensive data spanning 2759 Chinese counties from 2000 to 2018, this study pioneers an empirical investigation of the causal link between air pollution and child growth. The findings reveal a significant correlation between air pollution and child growth; as air pollution worsens, child growth suffers, evident in stunting, underweight, wasting, and severe wasting. More specifically, the effects of PM2.5 on stunting, underweight, and severe wasting can persist for up to six years, while its impact on wasting endures for three years. Vulnerable groups include older children, girls, and less-developed geographical regions. Environmental regulations like “Low-Carbon Cities” and “Air Pollution Prevention and Control Action Plan” have yielded positive growth outcomes. Mechanistically, PM2.5 impairs child growth via metabolic disruption and financial constraints. Collectively, this study offers empirical evidence of the adverse impacts of air pollution on child growth while proposing suggests strategies for addressing this challenge in developing countries.

空气污染对儿童成长的影响:来自中国县域广泛数据的证据
尽管人们对空气污染对健康的有害影响进行了广泛研究,但对空气污染对儿童生长影响的关注却十分有限。本研究利用 2000 年至 2018 年中国 2759 个县的综合数据,开创性地对空气污染与儿童生长之间的因果关系进行了实证调查。研究结果显示,空气污染与儿童生长之间存在显著的相关性;随着空气污染的恶化,儿童生长受到影响,表现为发育迟缓、体重不足、消瘦和严重消瘦。更具体地说,PM2.5 对发育迟缓、体重不足和严重消瘦的影响可持续长达六年,而对消瘦的影响可持续三年。易受影响的群体包括年龄较大的儿童、女童和欠发达地区。低碳城市 "和 "大气污染防治行动计划 "等环境法规产生了积极的增长效果。从机理上讲,PM2.5 会通过新陈代谢紊乱和经济限制损害儿童的生长。总之,本研究提供了空气污染对儿童成长不利影响的经验证据,同时提出了发展中国家应对这一挑战的策略建议。

期刊介绍: Global Environmental Change is a prestigious international journal that publishes articles of high quality, both theoretically and empirically rigorous. The journal aims to contribute to the understanding of global environmental change from the perspectives of human and policy dimensions. Specifically, it considers global environmental change as the result of processes occurring at the local level, but with wide-ranging impacts on various spatial, temporal, and socio-political scales. In terms of content, the journal seeks articles with a strong social science component. This includes research that examines the societal drivers and consequences of environmental change, as well as social and policy processes that aim to address these challenges. While the journal covers a broad range of topics, including biodiversity and ecosystem services, climate, coasts, food systems, land use and land cover, oceans, urban areas, and water resources, it also welcomes contributions that investigate the drivers, consequences, and management of other areas affected by environmental change. Overall, Global Environmental Change encourages research that deepens our understanding of the complex interactions between human activities and the environment, with the goal of informing policy and decision-making.
