Abstract：
BACKGROUND: Patterns of utilization of numerous smoking cessation methods among pregnant women amidst the increasing popularity of vaping (use of e-cigarettes) remains unknown.
METHODS: This study included 3,154 mothers who self-reported smoking around the time of conception and delivered live births in 2016-2018 in seven US states. Latent class analysis was used to identify subgroups of smoking women based on their utilization of 10 surveyed quitting methods and vaping during pregnancy.
RESULTS: We identified four subgroups of smoking mothers with different utilization patterns of quitting methods during pregnancy: 22.0% reported \"not trying to quit\"; 61.4% tried to \"quit on my own\" without any behavioral or pharmacological assistance; 3.7% belonged to the \"vaping\" subgroup; and 12.9% utilized \"wide-ranging methods\" with higher use rate of multiple approaches, such as quit line and nicotine patch. Compared to mothers \"not trying to quit,\" the subgroup trying to \"quit on my own\" were more likely to be abstinent (adjusted OR 4.95, 95% CI 2.82-8.35) or to reduce the number of cigarettes smoked daily (adjusted OR 2.46, 95% CI 1.31-4.60) in late pregnancy, and these improvements lasted into early postpartum. We did not observe a measurable reduction in smoking among the \"vaping\" subgroup or women trying to quit with \"wide-ranging methods\".
CONCLUSIONS: We identified four subgroups of smoking mothers with different utilization patterns of eleven quitting methods during pregnancy. Pre-pregnancy smokers who tried to \"quit on my own\" were most likely to be abstinent or to reduce smoking amount.

摘要：
背景：在vaping（使用电子烟）日益普及的情况下，孕妇使用多种戒烟方法的模式仍然未知。
方法：这项研究包括3,154名母亲，她们在怀孕前后自我报告吸烟，并在2016-2018年在美国七个州分娩了活产。潜在类别分析用于根据吸烟妇女对10种接受调查的戒烟方法和在怀孕期间使用电子烟的情况来识别吸烟妇女的亚组。
结果：我们确定了怀孕期间戒烟方法使用不同模式的吸烟母亲的四个亚组：22.0％的人报告“不尝试戒烟”；61.4％的人试图“自己戒烟”，而没有任何行为或药理帮助；3.7％属于“vaping”亚组；12.9％的人使用“广泛的方法”，多种方法的使用率更高，如戒烟线和尼古丁贴片。与“不试图戒烟”的母亲相比，“试图“自己戒烟”的亚组更有可能在妊娠晚期戒断（调整后OR4.95，95％CI2.82-8.35）或减少每日吸烟数量（调整后OR2.46，95％CI1.31-4.60），这些改善一直持续到产后早期。我们没有观察到“vaping”亚组或试图通过“广泛的方法”戒烟的女性中吸烟的可测量减少。
结论：我们确定了四个吸烟母亲亚组，在怀孕期间对11种戒烟方法的利用方式不同。试图“自己戒烟”的孕前吸烟者最有可能戒烟或减少吸烟量。
