关于母亲被动吸烟与早产风险之间关系的研究得出了不一致的结论。2010年至2012年期间，在中国兰州进行了一项出生队列研究，其中包括10，095名分娩单胎活产的非吸烟女性。妊娠期间被动吸烟与极早产风险增加相关（< 32周妊娠;比值比= 1.98，95%置信区间：1.41，2.76），但与中度早产风险无关（32-36周妊娠;比值比= 0.98，95%置信区间：0.81，1.19）。极早产风险随暴露持续时间增加（趋势P = 0.0014）。三个月的暴露量没有变化。医学指征和自发性早产的相关性是一致的。总的来说，我们的研究结果支持被动吸烟和极早产风险之间的正相关。
Studies investigating the relationship between maternal passive smoking and the risk of preterm birth have reached inconsistent conclusions. A birth cohort study that included 10,095 nonsmoking women who delivered a singleton live birth was carried out in Lanzhou, China, between 2010 and 2012. Exposure to passive smoking during pregnancy was associated with an increased risk of very preterm birth (< 32 completed weeks of gestation; odds ratio = 1.98, 95% confidence interval: 1.41, 2.76) but not moderate preterm birth (32-36 completed weeks of gestation; odds ratio = 0.98, 95% confidence interval: 0.81, 1.19). Risk of very preterm birth increased with the duration of exposure (P for trend = 0.0014). There was no variability in exposures by trimester. The associations were consistent for both medically indicated and spontaneous preterm births. Overall, our findings support a positive association between passive smoking and the risk of very preterm birth.
