AUSTIN, Texas — New research from The University of Texas at Austin suggests that many teenagers, especially younger teens, may not be getting the message about the risks of using alcohol and other drugs during pregnancy but that having involved parents and being engaged academically can help.
The study, led by Assistant Professor Christopher Salas-Wright at UT Austin’s School of Social Work and published in the Spring 2015 issue of Addictive Behaviors, examines the relationship between substance use and teen pregnancy using a large, nationally representative sample.
Nearly 3 in 5 (59%) pregnant teens reported having used one or more substances in the previous 12 months, a rate that is nearly two times as great as that of nonpregnant teens (35%). Additionally, the study suggests that use of these substances continues during pregnancy for many teens, particularly younger ones. More than one third (34%) of all pregnant adolescents ages 12-14 reported having used one or more substances during the previous 30 days. The substance use, however, decreases dramatically for all pregnant youths as they progress from the first into the second and third trimesters of pregnancy, according to the study. The most commonly used substance is alcohol (16%), followed closely by cannabis (14%), and finally other illicit drugs (5%).
“To our knowledge, this is the largest study to date on the relationship between substance use and teen pregnancy,” Salas-Wright said. “Mothers’ substance use during pregnancy can have important consequences for the health and development of newborn babies. Despite efforts to prevent substance use among pregnant teens, our findings suggest that we still have a lot of work to do.”
The study was co-authored with Michael G. Vaughn of Saint Louis University’s School of Social Work and graduate students Jenny Ugalde and Jelena Todic of The University of Texas at Austin’s School of Social Work.
