Smoking relapse prevention counseling during prenatal and early postnatal care.

Our objective was to examine the efficacy of the added effect of individualized smoking relapse prevention counseling on obstetricians' and nurse midwives' usual advice during prenatal care. One hundred and seventy-five pregnant women who were smoking early in their pregnancy, but had quit by first prenatal visit, were randomly assigned to receive the usual advice from their obstetrician or nurse midwife, or usual advice plus individual relapse prevention counseling. Smoking status was measured by self-report, by urinary cotinine/creatinine ratio at the 36-week visit, and by self-report at long-term postpartum follow-up. We found that a smaller percentage of women in the intervention group (8.8%) reported smoking at the thirty-sixth-week visit than those in the usual care group (16.9%), a nonsignificant difference. No significant difference in relapse rates during pregnancy was observed based on urinary cotinine/creatinine ratios, but these rates, 29.5% and 27.9% respectively, were substantially higher than those based on self-report. The average number of days abstinent reported by women in the intervention group was significantly longer than that in the usual care group, 199 days versus 166 days respectively (P < .01). Logistic regression analysis indicated that longest time abstaining before first visit, level of belief in smoking's harm to the fetus, and motivation to smoke were independently related to the probability of relapsing to smoking by the 36-week visit. Long-term relapse rates were not significantly different: intervention group, 50.9%, usual care group, 50.0%.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Training obstetric and family practice residents to give smoking cessation advice during prenatal care.

OBJECTIVE: Our objective was to determine the effectiveness of training obstetric and family practice residents to provide smoking cessation advice. STUDY DESIGN: The effectiveness of the trained residents' advice was assessed from exit interviews of pregnant smokers taking part in a randomized, controlled trial of smoking cessation advice. Exit interview responses were compared by chi 2 analysis. RESULTS: Training resulted in significant changes in the advice provided by the residents, with greater emphasis on gaining a commitment to smoking behavior change, but not in the average time providing the advice, approximately 3 minutes. Adherence to the protocol was maintained at 80%. Significantly more women who received the brief structured advice agreed to stop smoking (54%) or cut down their cigarette consumption (28%) compared with women in the control group (14% and 6%, respectively), p = 0.0001. CONCLUSION: The structured advice consistently provided by the trained residents was effective in gaining commitments from pregnant smokers to change their smoking behavior.
