Child Development

Evaluation of the Knit to Quit Program in Baltimore City (Sponsor: Lerner Center for Health Promotion)

Allison West
Despite robust evidence linking perinatal tobacco exposure with poor maternal and child outcomes, a majority of pregnant women receiving opioid maintenance medication treatment smoke cigarettes. B’more for Healthy Babies (BHB) and the Baltimore City Health Department (BCHD) designed Knit to Quit, a group intervention to support smoking cessation among clients and staff at local substance use disorder treatment and recovery programs serving women of reproductive age. The model integrates psychoeducation and motivational messaging within a semi-structured group knitting class to improve participants’ knowledge, self-efficacy, and motivation to quit, increase social support for quitting, reduce stress, and, ultimately, reduce tobacco use. The goal of this project is to evaluate implementation and effectiveness of the Knit to Quit intervention.
