The aim of the randomized trial was to evaluate the risk of smoking relapse one year after delivery among the women who quit smoking during pregnancy.
The study was carried out in 2002 and 2003 and included the collection of data on smoking relapse within one year after delivery among 175 women who participated in the randomized smoking cessation trial and quit smoking during pregnancy.
About 50% of women who quit smoking during pregnancy relapsed into that habit within 12 months postpartum. The analysis of women who quit smoking before 14 weeks of pregnancy revealed a significantly higher risk of smoking relapse after delivery for women with the higher level of smoking addiction indicated by the Fagerström test (OR = 5.0; 95% CI: 1.5-16.2). Compared to the control group, spontaneous quitters who participated in intervention activities during pregnancy showed lower risk of smoking relapse within one year after giving birth (OR = 0.3; 95% CI: 0.1-0.9). In the group of women who quit smoking after 14 weeks of gestation, the risk of smoking relapse postpartum was significantly higher for those with the higher Fagerström test score (OR = 4.8; 95% CI: 1.6-14.1). The risk of smoking relapse 12 months after delivery was lower for spontaneous quitters who participated in the intervention during pregnancy and for women who quit smoking after participation in the intervention activities than for controls (OR = 0.03; 95% CI: 0.01-0.2, OR = 0.1; 95% CI: 0.03-0.6).
Women who had higher score in the Fagerström test before quitting smoking had significantly higher risk of smoking relapse within 12 months after delivery. Anti-smoking intervention during pregnancy helps women to maintain smoking abstinence after delivery.
该随机试验的目的是评估孕期戒烟的女性在产后一年复吸的风险。
该研究于2002年和2003年开展，收集了175名参与随机戒烟试验且孕期戒烟的女性产后一年内复吸的数据。
孕期戒烟的女性中约50%在产后12个月内复吸。对在怀孕14周前戒烟的女性进行分析发现，通过法格斯特罗姆测试显示吸烟成瘾程度较高的女性产后复吸风险显著更高（比值比=5.0；95%置信区间：1.5 - 16.2）。与对照组相比，孕期参与干预活动的自然戒烟者产后一年内复吸风险较低（比值比=0.3；95%置信区间：0.1 - 0.9）。在妊娠14周后戒烟的女性组中，法格斯特罗姆测试得分较高者产后复吸风险显著更高（比值比=4.8；95%置信区间：1.6 - 14.1）。孕期参与干预的自然戒烟者以及参与干预活动后戒烟的女性产后12个月的复吸风险低于对照组（比值比=0.03；95%置信区间：0.01 - 0.2，比值比=0.1；95%置信区间：0.03 - 0.6）。
戒烟前法格斯特罗姆测试得分较高的女性在产后12个月内复吸风险显著更高。孕期的反吸烟干预有助于女性产后保持戒烟状态。
