    Abuse-Related Post-Traumatic Stress, Coping, and Tobacco Use in Pregnancy
    (2011-07-01) Lopez, William D.; Konrath, Sara H.; Seng, Julia S.
    Objective: To examine the relationship between trauma history, posttraumatic stress disorder (PTSD), coping, and smoking in a diverse sample of pregnant women, some of whom are active smokers. Design: Secondary analysis from a prospective study on PTSD and pregnancy outcomes. Setting: Maternity clinics at three health systems in the midwestern United States. Participants: Women age 18 or older (1,547) interviewed at gestational age fewer than 28 weeks. Methods: Participants were classified at nonsmokers, quitters (stopped smoking during pregnancy), and pregnancy smokers. Demographic, trauma, and pregnancy factors, substance use, and use of tobacco to cope were compared across groups. Logistic regression assessed the influence of these factors on being a smoker versus a nonsmoker and a quitter versus a pregnancy smoker. Results: Smokers differed from nonsmokers on all demographic risk factors (being African American, being pregnant as a teen, having lower income and less education, and living in high-crime areas), had higher rates of current and lifetime PTSD, and were more likely to report abuse as their worst trauma. Pregnancy smokers had lower levels of education, were more likely to classify their worst trauma as “extremely troubling,” and were more likely to exhibit PTSD hyperarousal symptoms. In regression models, smoking “to cope with emotions and problems” doubled the odds of continuing to smoke while pregnant even after accounting for several relevant risk factors. Conclusion: Smoking behavior in pregnancy may be influenced by the need to cope with abuse-related PTSD symptoms. Clinicians should consider using trauma-informed interventions when working with tobacco-using pregnant women.

    Post-traumatic stress disorder (PTSD) genetics are characterized by lower discoverability than most other psychiatric disorders. The contribution to biological understanding from previous genetic studies has thus been limited. We performed a multi-ancestry meta-analysis of genome-wide association studies across 1,222,882 individuals of European ancestry (137,136 cases) and 58,051 admixed individuals with African and Native American ancestry (13,624 cases). We identified 95 genome-wide significant loci (80 new). Convergent multi-omic approaches identified 43 potential causal genes, broadly classified as neurotransmitter and ion channel synaptic modulators (for example, GRIA1, GRM8 and CACNA1E), developmental, axon guidance and transcription factors (for example, FOXP2, EFNA5 and DCC), synaptic structure and function genes (for example, PCLO, NCAM1 and PDE4B) and endocrine or immune regulators (for example, ESR1, TRAF3 and TANK). Additional top genes influence stress, immune, fear and threat-related processes, previously hypothesized to underlie PTSD neurobiology. These findings strengthen our understanding of neurobiological systems relevant to PTSD pathophysiology, while also opening new areas for investigation.
