NCT02210832

Brief Summary

Investigators will examine whether adding financial incentives to current best practices for smoking cessation during pregnancy (i.e., referral to pregnancy-specific counseling using a telephone quit line) increases cessation rates and improves infant health. While more expensive upfront compared to best practices alone, the investigators hypothesize that this treatment approach will be economically justified by the later cost savings associated with more women quitting, having healthier babies, and needing less healthcare. It should also help to reduce the greater risk for health problems often seen among those who less well off economically.

Outcome Measures

Primary Outcomes (1)

  • 7-day Point Prevalence Abstinence Levels at Final Antepartum Assessment

    Abstinence was defined as woman reports that she has not smoked, not even a puff, in the past 7 days and self-report is biochemically verified via urine cotinine testing

    collected once per women at approximately 28-weeks gestation in each of the two smoking arms

Secondary Outcomes (14)

  • 7-day Point Prevalence Abstinence Postpartum

    Repeated assessments completed at 2-, 4-, 8-, 12-, 24-, and 48-weeks postpartum

  • Breastfeeding in the Three Trial Arms

    Repeated assessments completed at 2-, 4-, 8-, 12-, 24-, and 48-weeks postpartum

  • Breastfeeding While Abstinent From Smoking

    Repeated assessments completed at 2-, 4-, 8-, 12-, 24-, and 48-weeks postpartum

  • Craving Item From the Minnesota Nicotine Withdrawal Scale (MNWS).

    Outcomes reported for 8 assessments (early pregnancy, late pregnancy, 2, 4, 8, 12, 24, 28 weeks postpartum.

  • Nicotine Withdrawal Total Scores for the Two Smoking-cessation Trial Conditions.

    Outcomes reported for 8 assessments (early pregnancy, late pregnancy, 2, 4, 8, 12, 24, 28 weeks postpartum.

  • +9 more secondary outcomes

Other Outcomes (1)

  • Additional Birth Outcome: Mean Birth Weight

Best practices for pregnant smokers

EXPERIMENTAL

Five As plus referral to pregnancy-specific tobacco quit line

Behavioral: Best practices

Best practices plus financial incentives

EXPERIMENTAL

Best practices plus providing financial incentives contingent on biochemically verified abstinence. Incentives are in the form of vouchers exchangeable for retail items and available through 12-weeks postpartum.

Behavioral: Best practicesBehavioral: financial incentives

Never-smoker comparison condition

NO INTERVENTION

We will follow a group of never-smoker pregnant women matched to smokers on key sociodemographic and obstetrical characteristics for purposes of comparisons in birth/health outcomes at delivery and through 1 year postpartum
