OBJECTIVES
This study is an evaluation of relapse prevention interventions for smokers who quit during pregnancy.
METHODS
Pregnant smokers at 2 managed care organizations were randomized to receive a self-help booklet only, prepartum relapse prevention, or prepartum and postpartum relapse prevention. Follow-up surveys were conducted at 28 weeks of pregnancy and at 8 weeks, 6 months, and 12 months postpartum.
RESULTS
The pre/post intervention delayed but did not prevent postpartum relapse to smoking. Prevalent abstinence was significantly greater for the pre/post intervention group than for the other groups at 8 weeks (booklet group, 30%; prepartum group, 35%; pre/post group, 39%; P = .02 [different superscripts denote differences at P < .05]) and at 6 months (booklet group, 26%, prepartum group, 24%; pre/post group, 33%; P = .04) postpartum. A nonsignificant reduction in relapse among the pre/post group contributed to differences in prevalent abstinence. There was no difference between the groups in prevalent abstinence at 12 months postpartum.
CONCLUSIONS
Relapse prevention interventions may need to be increased in duration and potency to prevent post-partum relapse.
目的
本研究旨在评估针对孕期戒烟者的预防复吸干预措施。
方法
在2家管理式医疗组织中的孕期吸烟者被随机分为仅接受一本自助手册、产前预防复吸或产前及产后预防复吸三组。在妊娠28周以及产后8周、6个月和12个月进行随访调查。
结果
产前/产后干预虽延迟但未能预防产后复吸。在产后8周（手册组30%；产前组35%；产前/产后组39%；P = 0.02[不同上标表示P < 0.05时的差异]）和6个月（手册组26%，产前组24%；产前/产后组33%；P = 0.04）时，产前/产后干预组的持续戒烟率显著高于其他组。产前/产后组复吸率的非显著降低导致了持续戒烟率的差异。产后12个月时，各组间的持续戒烟率无差异。
结论
可能需要延长预防复吸干预措施的时长并增强其效力，以预防产后复吸。
