A Study to Test Feasibility and Acceptability of an Intervention Program Aiming to Reduce Prenatal Secondhand Smoke Exposure

Feasibility and Acceptability of a Digital Intervention Program Aiming to Reduce Secondhand Smoke Exposure in Pregnancy: a Pilot Study

This pilot study assess the feasibility and acceptability of the "First Breath" digital behavioral intervention aiming to reduce prenatal SHS exposure. By involving both the pregnant women and partners (who smoke) of pregnant women, our intervention encourages reducing secondhand smoke exposure at home and in the car, through a gradual, capacity and self-efficacy building, structured plan. "First Breath" focus on raising knowledge about the health consequences of prenatal secondhand exposure, proposing strategies to avoid exposure, and raising motivation to implement a smoke free home and car. Our intervention also includes personal biochemical feedback to the pregnant women using urine cotinine (a marker of secondhand smoke exposure), and advice on using nicotine-replacemnt therapy within the home setting to avoid smoking.
