Hypothesis
Does a structured smoking cessation program for pregnant women and their partners affect smoking behavior during pregnancy?
Conclusion
The smoking intervention program did not significantly change parental smoking behavior during pregnancy, although a higher quitting rate was observed in Trondheim compared to Bergen.
Supporting Evidence
- Maternal smoking prevalence was lower in the intervention cohort at inclusion compared to the control cohort.
- 72% of maternal smokers in the intervention cohort still smoked six weeks postnatal.
- A higher quitting rate was observed in Trondheim compared to Bergen in 2003 and 2004.
Takeaway
The study tried to help pregnant women stop smoking, but most had already quit before the program started.
Methodology
The study used sequential birth cohorts to evaluate a smoking cessation program from 2000 to 2004, comparing smoking behavior in intervention and control groups.
Potential Biases
Possible selection bias due to differences in participation rates and characteristics between cohorts.
Limitations
High loss to follow-up and potential bias due to the one-year time difference between cohorts.
Participant Demographics
Participants included pregnant women from Trondheim, with a mix of primiparous and multiparous women.
