Twelve-month follow-up of a smoking relapse prevention intervention for postpartum women

This study examined the long-term effectiveness of a postpartum smoking rel apse prevention intervention by evaluating the smoking status and smoking c essation self-efficacy of original study participants at 12 months followin g delivery. Two hundred and thirty-eight women who had participated in a ra ndomized clinical trial. a nurse-delivered relapse prevention intervention, were visited in their homes. Data were collected on smoking status, self-e fficacy, mental health, alcohol use, breast feeding. social support, smokin g in the social environment, and sociodemographics. Smoking status was veri fied with measures of carbon monoxide in expired air. The 12-month continuo us smoking abstinence rate was 21.0% in the treatment group and 18.5% in th e control group; odds ratio (OR) = 1.17. 95% confidence interval (CI) = 0.6 2-2.22. One half (50.4%) of the control group and 41.2% of the treatment gr oup reported smoking daily at 12 months; OR = 1.45, 95% CI = 0.87-2.43. The treatment group attained higher self-efficacy. Four variables were associa ted with relapse to daily smoking; breast feeding and mental health had pro tective effects. while partners who smoked and greater amount smoked prior to pregnancy had adverse effects.
