Study Summary

Smoking is the most important modifiable risk factor for adverse pregnancy outcomes including preterm birth, neonatal death, and maternal complications. Rates of smoking cessation during pregnancy are low, particularly in underserved populations, and currently approved pharmacotherapies for smoking cessation either are considered unsafe in pregnancy or have uncertain effectiveness. Identifying safe and effective interventions, which might mitigate the adverse effects of smoking on maternal-fetal outcomes, is a major public health priority. We hypothesize that smoking-induced n-3 LCPUFA relative deficiencies may be an important mechanism contributing to tobacco-related adverse pregnancy outcomes and that n-3 LCPUFA supplementation specifically targeted to pregnant smokers may reduce these complications. Support for this hypothesis comes from a recent secondary analysis of the Omega-3 Fatty Acids Supplementation to Prevent Preterm Birth trial that found that only smokers taking n-3 LCPUFAs had a reduction in preterm labor risk as compared to non-smokers. While compelling, this study was a post hoc analysis that included only a small sample of smokers and did not collect data on smoking behaviors during follow up. Yet the ascertainment of longitudinal smoking behavior is critical, as some clinical studies have found that supplemental n-3 LCPUFAs might also reduce nicotine cravings, and lower daily cigarette use. Thus, smokers may doubly benefit from replenishing n-3 LCPUFAs via lower risk of preterm labor and/or increased smoking cessation. To address these knowledge gaps, we are proposing a multi-center, randomized, placebo-controlled, double-blinded study of n-3 LCPUFA supplementation in 400 pregnant smokers. We will collect detailed information on smoking behavior, validated biological markers of cigarette exposure (urinary cotinine, end-expiratory carbon monoxide) and biomarkers of n-3 LCPUFA status (red blood cell phospholipid membrane fatty acids).
