About this study

This is a randomized controlled trial to prevent postpartum smoking relapse by breastfeeding promotion. The intervention group (N=30) will receive multicomponent breastfeeding intervention from late pregnancy to 6 months postpartum, while the attention placebo control group (N=30) will receive general infant care counseling and support. The key outcome is the rate of postpartum smoking relapse.

Read the detailed description

The investigators propose the first randomized controlled trial to reduce postpartum smoking relapse by breastfeeding promotion from late pregnancy to 6 months postpartum. The investigators will enroll 60 pregnant women who successfully quit smoking within 3 months before or during this pregnancy (<28 weeks). All participants will receive breastfeeding education during late pregnancy. Right after delivery, participants who are still smoking abstinent will be randomized into either the breastfeeding intervention group (N=30) or the attention placebo control group (N=30). The intervention group will receive multicomponent interventions consisting of postnatal lactation counseling, family/peer/employer support, contingent financial incentives, and early limited formula milk via syringe (optional for at-risk infants). The control group will receive counseling and support focusing on general infant care with attention and compensation similar to the intervention group. The primary outcomes are rates of postpartum smoking relapse verified by urine cotinine test.

Specific Aim 1 is to examine the efficacy of breastfeeding promotion intervention on postpartum smoking relapse. Specific Aim 2 is to collect preliminary data regarding potential mediating mechanisms: increases in lactation hormones (plasma oxytocin and prolactin), reductions in stress and negative affect, and enhancing mother-infant bonding and maternal motivation to protect the infant from secondhand smoke exposure. This innovative and feasible pilot study can yield promising preliminary data to strongly support our future application of a NIH R01 grant proposal that has the potential to reduce smoking-related harms to both the mother and the infant, and maximize the protective effects of breastfeeding on infant health and development.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Breastfeeding promotionBehavioural

    The intervention group will receive multicomponent interventions consisting of 7 half-hour postnatal visits for lactation counseling, family/peer/employer support, contingent financial incentives, and early limited formula milk via syringe (optional for at-risk infants).

  • Attention placebo controlBehavioural

    The attention placebo control group will complete the same frequency and duration of study visits as the intervention group but focus on general infant care counseling and support.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Reporting to Breastfeed

    During postpartum, mothers report their breastfeeding status (exclusive, mixed with formula, non-breastfeeding) every month until 9 months postpartum. Any breastfeeding is defined as exclusive breastfeeding or mixed-feeding breast milk and formula.

    Measured: 9 months postpartum
