交通来源污染物与不良出生结局关系的研究进展

Advances in research on adverse birth outcomes associated with traffic-derived pollutants

  • 摘要:

    近年来,交通来源污染物与不良出生结局的关系日益引起各国科学家的重视,并陆续开展相关研究。越来越多的流行病学研究发现,交通来源污染物如细颗粒物、氮氧化物、臭氧、一氧化碳暴露会增加早产、低出生体重、小于胎龄儿和宫内发育迟缓的风险,但也有一些研究未发现交通来源污染相关指标与不良出生结局的联系,其原因主要是暴露评估存在偏倚及未对混杂因素进行控制。本文介绍了细颗粒物、氮氧化物、臭氧、一氧化碳、交通密度和距离等暴露评价指标及其特点,总结了其对早产、低出生体重、小于胎龄儿和宫内发育迟缓产生的影响,以得出现有研究中存在的不足及未来研究的方向,旨在为后续研究提供有益的线索及开创性思路。

     

    Abstract:

    In recent years, the relationship between traffic pollution and adverse birth outcomes has attracted increasing attention from scientists all over the world. A growing number of epidemiological studies have found that increased exposure to traffic-derived pollutants such as fine particulate matters, nitrogen oxides, ozone, and carbon monoxide are associated with higher risks of preterm birth, low birth weight, small for gestational age, and intrauterine growth retardation, but a few studies have not found such associations. The main reasons for the difference were biased exposure assessment and the lack of controlling confounders. This paper introduced exposure evaluation indexes and characteristics of particulate matters, nitrogen oxides, ozone, carbon monoxide, and traffic density and distance, and summarized their effects on preterm birth, low birth weight, small for gestational age, and intrauterine growth retardation, aiming to provide useful clues and innovative ideas for future research.
