NCT05740098

Brief Summary

Investigators will examine whether adding financial incentives and nicotine replacement dual therapy to current best practices for smoking cessation (i.e. referral to counseling using a telephone quit line) increases cessation rates in mothers and reduces second-hand smoke exposure in children. While perhaps more expensive upfront compared to best practices alone, the investigators hypothesize that this treatment approach will be a more cost-effective cessation intervention.

Outcome Measures

Primary Outcomes (2)

  • 7-day Point Prevalence Smoking Abstinence Levels

    Point prevalence abstinence will be defined as self-report of no smoking in the past 7 days, not even a puff, with biochemical verification via breath carbon monoxide (CO) and urine cotinine. Abstinence at the 12-week (end of treatment) and 24-week assessment will be compared between the three treatment arms.

    Collected once per woman at approximately 12- and 24- weeks following quit date in each of the three smoking arms

  • Objective Measure of Child Secondhand Smoke Exposure (SHSe)

    SHSe will be defined as the level of cotinine measured in the urine of the youngest child at baseline, 6-, 12-, and 24-weeks following the mother's quit date. SHSe outcomes will be compared between the three treatment arms and between children of abstainers versus smokers independent of treatment condition. We hypothesize being able to detect greater reductions from baseline levels in the incentives compared to Best Practices treatment conditions and among abstainers compared to smokers. We report main effects of treatment condition as geometric means (+/- SEM) collapsed across the three assessment times for each treatment condition controlling for baseline values.

    Collected twice per child at baseline, and once at approximately 6-, 12- and 24-weeks following quit date

Secondary Outcomes (4)

  • Continuous Abstinence

    24 weeks following quit date

  • 7-day Point Prevalence Abstinence at 48-week Follow-up Assessment

    48 weeks following quit date

  • Smoking Abstinence

    Assessed once per woman at 6-, 12-, 24-, and 48-weeks following quit date.

  • Smoking Abstinence

    Collected once per woman at baseline, 6-, 12-, 24-, and 48-weeks following quit date.

Other Outcomes (4)

  • Number of Outpatient Child Visits to Healthcare Center.

    48 weeks following quit date.

  • Number of Inpatient Child Visits to Healthcare Center.

    48 weeks following quit date.

  • Number of Times Child Received Prescription Medications.

    48 weeks following quit date.
