This multicenter randomized controlled trial analyzed pooled data from 1409 pregnant women to identify predictors of quit attempts and smoking abstinence. Key findings indicate that higher intention to quit (OR = 1.50) and self-efficacy (OR = 1.60) significantly predicted quit attempts, while a greater reduction in cigarettes smoked early in pregnancy (OR = 1.02) and longer previous abstinence were linked to successful smoking cessation.
Key findings
- Higher intention to quit was associated with a 1.50 odds ratio for making a quit attempt.
- A higher self-efficacy score predicted quit attempts with an odds ratio of 1.60.
- A greater percentage reduction in cigarettes smoked early in pregnancy had an odds ratio of 1.02 for smoking abstinence.
- Longer previous quit attempts were statistically significant predictors of smoking abstinence.
Why it matters
Understanding the predictors of smoking cessation in pregnancy is crucial for developing effective interventions. This study highlights the importance of motivational factors and early behavioral changes, which can inform clinical strategies to support pregnant women in quitting smoking.
