摘要
目的探讨大气污染对妊娠结局的影响。方法收集太原市1997—2004年6个国控监测点大气PM10和SO2浓度资料以及同期妊娠结局的资料,对妊娠结局的相关危险因素及不同妊娠时期大气中PM10和SO2浓度对妊娠结局的影响进行分析。结果空气中PM10和SO2浓度每增加100μg/m3与妊娠结局的Logistic回归结果表明,PM10空气污染对早产、出生缺陷和死胎死产有显著影响,早产的OR值为1.17～1.76,最高OR值为1.76(95%CI:1.64～1.90),出现在怀孕前3个月;出生缺陷的OR值为1.37～1.67,最高OR值为1.67(95%CI:1.28～2.17),出现于第3个孕月。关于SO2空气污染,只观察到对早产的显著影响,且发生于第1、2个孕月,相应的OR值分别为1.27(95%CI:1.21～1.34)和1.07(95%CI:1.01～1.14)。结论太原市空气污染已对妊娠结局造成一定影响,应采取严格的空气污染控制措施,降低不良妊娠结局发生率。
Objective To explore the association between air pollution and the pregnancy outcome in a severe air pollution city and to provide the evidence for health related policy-making.Methods The subject population included the newborns from 1997 to 2004 in Taiyuan and the data of air pollution in the same time were collected.Logistic regression was used to analyze OR in the case-control design.Results Statistically,the prevalence of premature birth,birth defects and the mortality of infants and fetuses were signi...
