This cross-sectional study investigated the prevalence of smoking and secondhand smoking (SHS) among pregnant women in Darkhan-Uul Province, Mongolia, using urinary cotinine (UC) levels, and clarified the factors related to SHS exposure. It targeted pregnant women who underwent antenatal health check-ups from November 2015 to January 2016. Self-administered questionnaires and urine samples were used to collect data. Using UC levels as the criterion, it was found that the prevalence of smokers (>100 ng/ml) among 493 pregnant women was 11.8%, while SHS exposure (≥5 ng/ml) among nonsmokers was 44.8%. Older and highly educated women had lower odds of SHS exposure (p = 0.006 and 0.002, respectively). Furthermore, nonsmoking pregnant women from homes where smoking was permitted had higher odds of SHS exposure compared to women from homes where smoking was not permitted. These results suggest that community guidance programs, such as home smoking cessation that include families, are necessary.
本横断面研究使用尿液可替宁（UC）水平调查了蒙古达尔汗乌勒省孕妇的吸烟和二手烟（SHS）流行情况，并阐明了与 SHS 暴露相关的因素。它的目标人群是 2015 年 11 月至 2016 年 1 月期间进行产前健康检查的孕妇。研究使用自填式问卷和尿液样本收集数据。根据 UC 水平作为标准，发现 493 名孕妇中吸烟者（>100ng/ml）的患病率为 11.8%，而不吸烟者的 SHS 暴露（≥5ng/ml）患病率为 44.8%。年龄较大和受教育程度较高的女性 SHS 暴露的可能性较低（p=0.006 和 0.002）。此外，与家中不允许吸烟的孕妇相比，家中允许吸烟的不吸烟孕妇 SHS 暴露的可能性更高。这些结果表明，需要开展社区指导计划，如包含家庭的家庭戒烟计划。
