背景：虽然怀孕期间吸烟流行的趋势是已知的，但对怀孕期间戒烟和怀孕后恢复吸烟的趋势知之甚少。目的：本研究探讨了怀孕期间戒烟和怀孕后恢复吸烟的趋势及其相关性。方法：我们在1993年至1999年间对美国10个州（共115,000名妇女）的新母亲进行了基于人口的随机调查。结果：虽然怀孕前3个月的吸烟率稳定在26%左右，但在1993年至1999年期间，怀孕期间戒烟率从37%上升到46%。根据产妇和州的特点调整后，1993年至1999年间，怀孕期间戒烟的几率增加了51%（优势比[OR]=1.51； 95%可信区间[CI]=1.08-2.12）。大约一半在怀孕期间戒烟的妇女在产后6个月内又开始吸烟。与多胞胎、有医疗保险和高中学历的女性相比，初产的、有私人保险的、受过大学教育的女性更有可能在分娩后戒烟，而恢复吸烟的可能性最小。青少年女性戒烟的可能性更大，但也比老年女性更容易重新吸烟。结论：怀孕期间戒烟率的增加是令人鼓舞的，但怀孕前吸烟或产后复发率没有任何变化，这表明需要额外关注产妇吸烟的永久性改变。
Background: While trends in smoking prevalence during pregnancy are known, little is known about trends in quitting during pregnancy and resuming smoking after pregnancy.Objectives: This study examined the trends in and correlates of quitting during pregnancy and resuming smoking after pregnancy.Methods: We used population-based random surveys of recent mothers in ten U.S. states (total of 115,000 women) conducted between 1993 and 1999.Results: Although the prevalence of smoking 3 months before pregnancy was stable at around 26%, quitting during pregnancy rose from 37% to 46% between 1993 and 1999. Adjusted for maternal and state characteristics, the odds of quitting during pregnancy increased 51% between 1993 and 1999 (odds ratio [OR]=1.51; 95% confidence interval [CI]=1.08-2.12). Approximately half of the women who quit smoking during pregnancy resumed smoking within 6 months postpartum. Primiparous, privately insured, college-educated women are more likely to quit and least likely to resume smoking after delivery, compared to multiparous, Medicaid-insured, and high school-educated women. Teenaged women are more likely to quit, but also more likely to resume smoking than older women.Conclusions: The increase in quit rates during pregnancy is encouraging, but the lack of any change in smoking before pregnancy or in postpartum relapse rates suggests that permanent changes in maternal smoking will require additional focus.
