Summary
Postpartum smoking relapse is high (62.9%) among women who quit during pregnancy. Key relapse predictors include late-pregnancy smoking, social/partner smoking, and low confidence in maintaining abstinence.
Area of Science:
- Public Health
- Reproductive Health
- Addiction Medicine
Background:
- Postpartum smoking relapse rates are high despite successful smoking cessation during pregnancy.
- Understanding predictors of relapse is crucial for developing effective interventions.
Purpose of the Study:
- To determine the probability of smoking relapse in the first 6 months postpartum among women who successfully quit during pregnancy.
- To identify factors associated with increased risk of postpartum smoking relapse.
Main Methods:
- Prospective and retrospective study design using survival analysis and Cox proportional hazards regression.
- Data collected via questionnaires and telephone interviews, with urine cotinine tests for verification.
- Followed 127 women from a prenatal smoking cessation trial in Los Angeles.
Main Results:
- 62.9% of participants relapsed to smoking within 6 months postpartum.
- Risk factors for relapse included late-pregnancy smoking, friends who smoke, low confidence in maintaining abstinence, and a smoking partner.
Conclusions:
- Interventions should target late pregnancy and address social networks, including partner smoking.
- Enhancing confidence in postpartum abstinence is a potential intervention target.
