This study examined the postpartum relapse rates and characteristics of pregnant women who stopped smoking without professional intervention. Baseline characteristics of women who spontaneously quit were compared to women who continued to smoke. Women who spontaneously quit were also randomized to a psychotherapy relapse prevention treatment, or to usual care. The sample was ethnically diverse, containing 141 low-income women who were predominantly Hispanic, 23% (n=33) of whom spontaneously quit smoking. The variables that significantly differentiated between "spontaneous quitters" and ongoing smokers were entered into a regression analysis, which revealed that higher self-confidence, smoking fewer cigarettes per day, and younger age accounted for 25% of the variance in spontaneous cessation. Adding the psychotherapy intervention conferred no additional protection against relapse in this subgroup of spontaneous quitters. The six-month abstinence rate of 36% is similar to that found in Caucasian and higher-income populations. These results extend research with pregnant smokers to a new population and may have implications for healthcare providers and policy makers.
本研究调查了在没有专业干预的情况下戒烟的孕妇产后复发率及特征。将自然戒烟女性的基线特征与继续吸烟的女性进行比较。自然戒烟的女性也被随机分为接受心理治疗预防复发组或常规护理组。样本种族多样，包括141名主要为西班牙裔的低收入女性，其中23%（n = 33）自然戒烟。将“自然戒烟者”与持续吸烟者显著区分开的变量纳入回归分析，结果显示更高的自信心、每天吸烟量较少以及年龄较小可解释自然戒烟差异的25%。在这个自然戒烟者亚组中，增加心理治疗干预并未对预防复发提供额外保护。36%的六个月戒烟率与白种人和高收入人群中的戒烟率相似。这些结果将对孕期吸烟者的研究扩展到了新的人群，可能对医疗保健提供者和政策制定者具有启示意义。
