绿色空间对大气污染相关不良妊娠结局的影响

Effects of green space on adverse birth outcomes induced by air pollution

大气污染已经成为世界范围内重要的公共卫生问题。妊娠期暴露于大气污染是早产、低出生体重、出生缺陷等不良妊娠结局增加的重要危险因素之一。目前,大气污染治理任重道远,因此,分析并识别相关的保护性因素显得极为迫切。有研究显示绿色空间可能是大气污染相关不良妊娠结局的一个保护性因素,此类研究主要通过分析卫星监测数据,量化以孕妇家庭住址为中心,一定范围缓冲区的绿色空间,分析绿色空间对大气污染相关的不良妊娠结局的修正作用。本文主要从绿色空间数据的使用,绿色空间对大气污染与不良妊娠结局关系的修正作用及其可能的机制等方面进行综述,有助于阐明绿色空间对大气污染相关不良妊娠结局的影响,为公共卫生的干预策略提供科学依据。

Air pollution has become one of the most important public health problems worldwide.Exposure to air pollution during pregnancy is one of the important risk factors for adverse birth outcomes such as preterm birth,low birth weight,and birth defects.Air pollution control has a long way to go.Therefore,it is extremely urgent to analyze and identify relevant protective factors.Some studies have shown that green space may be a protective factor for the adverse birth outcomes related to air pollution.This kind of research mainly utilizes satellite monitoring data,quantifies the green space coverage level in a certain range of buffer zone centered on the pregnant women’s home addresses,and analyzes its mediation effect on the adverse pregnancy outcomes related to air pollution.In this paper we reviewed the use of green space data,the estimated effect of green space mediating the relationship between air pollution and adverse birth outcomes,and its possible mechanisms,aiming to clarify the impact of green space on adverse birth outcomes related to air pollution and provide a scientific basis for public health intervention strategies.
