MedicalResearch.com Interview with: Jamie A. Seabrook, Ph.D. Associate Professor, School of Food and Nutritional Sciences Brescia University College at Western University Adjunct Research Professor, Dept of Paediatrics, Western University Adjunct Associate Professor, Dept of Epidemiology & Biostatistics, Western University Scientist, Children's Health Research Institute Scientist, Lawson Health Research Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Alcohol, tobacco, and cannabis are the most commonly used substances during pregnancy. High alcohol consumption has been linked with preterm birth, and tobacco and/or cannabis use is associated with low birth weight. Much of what we know about predictors of drug use during pregnancy comes from the United States and Australia, with limited studies in Canada. The objective of our study was therefore to assess the relative effects of socioeconomic, demographic, and mental health risk factors associated with drug use during pregnancy. Our retrospective cohort study consisted of 25,734 pregnant women from Southwestern Ontario. We found that maternal depression was the top risk factor associated with all three substances. Compared to women who were not depressed during their pregnancy, women who were depressed were 2.2 times more likely to use alcohol (95% CI: 1.6, 2.9), 1.7 times more likely to smoke tobacco (95% CI: 1.5, 2.0), and 2.6 times more likely to use cannabis (95% CI: 2.0, 3.4).
