Smoking in pregnancy poses serious health risks to the fetus and mother. Unfortunately, about half of women continue to smoke when becoming pregnant; this rate has not decreased significantly in the past decade. Effective interventions clearly are needed. Promisingly, most women reduce smoking when learning of their pregnancy, and most report desiring to quit via reduction rather than cold turkey. However, self-weaning often is ineffective and undermines total cessation efforts. Scheduled gradual reduction (SGR) might be an effective way to promote cessation among pregnant women. SGR, along with cognitive behavioral counseling, has been shown to help non-pregnant smokers quit above cold turkey or self-weaning methods. SGR might be ideally delivered via a method like SMS text messaging, with which most pregnant smokers are familiar. Our pilot work shows feasibility, acceptability, and preliminary efficacy of this SGR + CBT program. The end product of this work would a disseminable ready-to-be-implemented program. The proposed five-year study is designed to evaluate the efficacy of SGR plus CBT via SMS text messaging in promoting smoking cessation among a racially diverse sample of pregnant smokers. Proposed is a two-arm randomized controlled design. Eligible pregnant women (N=522, 261 per arm) will be randomized to: Arm 1, SGR via SMS text messaging plus SMS Support Messages and self-help materials (n=261) or Arm 2, SMS Support Messages and self-help materials (n=261). The primary outcome measure is biochemically validated 7-day point prevalent abstinence at the end of pregnancy. Secondary outcomes are prolonged abstinence at the end of pregnancy, biochemically-validated smoking reduction during pregnancy, smoking abstinence at 3-months postpartum, and preterm birth. The significance of this project is that no easily disseminable effective programs exist to help pregnant women quit smoking. An automated, tailored text messaging intervention shows promise to reach many pregnant women and reduce smoking during pregnancy.

怀孕的吸烟给胎儿和母亲带来严重的健康风险。不幸的是，怀孕时约有一半的妇女继续吸烟。在过去的十年中，这种速度尚未显着降低。显然需要有效的干预措施。有希望的是，大多数妇女在得知怀孕时会减少吸烟，并且大多数报告希望通过减少而不是冷火鸡戒烟。但是，自我断奶通常是无效的，并且破坏了全面的停止工作。预定的逐渐减少（SGR）可能是促进孕妇停止的有效方法。 SGR以及认知行为咨询已被证明可以帮助非孕妇吸烟者在冷火鸡或自断奶方法上退出。理想情况下，SGR可以通过SMS文本消息传递来交付，大多数怀孕的吸烟者都熟悉。我们的飞行员工作显示了该SGR + CBT计划的可行性，可接受性和初步功效。这项工作的最终产品将是一个可连接的即将实现的程序。拟议的五年研究旨在通过SMS文本消息传递评估SGR加CBT的功效，以促进种族多样的孕妇吸烟者样本中的戒烟。提议的是两臂随机控制设计。合格的孕妇（n = 522，261每臂）将随机分为：ARM 1，通过SMS文本消息和SMS支持消息和自助材料（n = 261）或ARM 2，SMS支持消息和自助材料（n = 261）。主要结局措施是在怀孕结束时在生化验证的7天点盛行。次要结局在怀孕结束时长期禁欲，怀孕期间的生化降低吸烟，产后3个月的戒烟以及早产。该项目的意义在于，没有很容易分发有效的有效计划来帮助孕妇戒烟。自动量身定制的文本消息干预措施显示出有望吸引许多孕妇并减少怀孕期间的吸烟。
