Individualized smoking cessation counseling during prenatal and early postnatal care.

OBJECTIVE

We examined the efficacy of individualized smoking cessation counseling added to obstetricians' and nurse-midwives' advice.

STUDY DESIGN

In a mixed private and publicly supported prenatal clinic 600 pregnant women who smoked were randomly assigned to receive the usual advice from their obstetrician or nurse-midwife or the usual advice plus individualized smoking cessation counseling. Smoking status was measured by self-report and urinary cotinine/creatinine ratios at 36 weeks and by self-report during long-term postpartum follow-up.

RESULTS

Quitting rates during pregnancy were not increased by adding individualized smoking cessation counseling to usual care. At the long-term follow-up, reported quitting rates were significantly greater among intervention group women cared for in the publicly supported clinic than among those receiving the usual care, 14.5% versus 2.5%, p < 0.01.

CONCLUSION

Although adding individual smoking cessation counseling did not increase quitting rates during pregnancy, it should be considered for women in public maternity clinics because of its potential long-term effectiveness.
