Smoking Reduction In Gravid Women With Substance Use Disorders (SIGS): A Randomized Controlled Trial

University of Alabama at Birmingham·interventional·Posted Oct 18, 2019·Updated Aug 5, 2024

In Brief

A clinical study evaluating knowledge of expired maternal carbon monoxide and fetal carboxyhemoglobin levels for Tobacco Smoking in Mother Complicating Pregnancy and 2 related conditions. Completed, enrolled 74 participants across 1 site.

Detailed Summary

The aim of this study is to encourage smoking cessation in women with substance use disorders by providing knowledge of expired carbon monoxide. We hypothesize that women who are provided knowledge of their expired carbon monoxide and the associated percent fetal carboxyhemoglobin will have a greater success at quitting smoking during pregnancy than women who are not provided this information. A secondary aim of the study is to correlate expired carbon monoxide throughout pregnancy with infant birth weight.
