Design: Randomised controlled non-blinded trial analysed by intention to treat. Setting: Clinics attached to two maternity hospitals in Glasgow. Participants: 762/1684 pregnant women who were regular smokers at antenatal booking: 351 in intervention group and 411 in control group. Interventions: All women received standard health promotion information. Women in the intervention group were offered motivational interviewing at home. All interviews were recorded. Main outcome measures: Self reported smoking cessation verified by plasma or salivary cotinine concentration. Results: 17/351 (4.8% ) women in the intervention group stopped smoking (according to self report and serum cotinine concentration < 13.7 ng/ml) compared with 19/411 (4.6% ) in the control group. Fifteen (4.2% ) women in the intervention group cut down (self report and cotinine concentration less than half that at booking) compared with 26 (6.3% ) in the control group. Fewer women in the intervention group reported smoking more [18 (5.1% ) v 44 (10.7% ); relative risk 0.48, 95% confidence interval 0.28 3078 g v 3048 g]. Conclusion: Good quality motivational interviewing did not significantly increase smoking cessation among pregnant women.展开更多
