Abstract
- Maternal tobacco and cannabis use during pregnancy are associated with adverse perinatal outcomes. We hypothesized that maternal tobacco and cannabis use are associated with placental adaptations, which subsequently lead to adverse perinatal outcomes. In a population-based prospective cohort study of 8008 pregnant women, we assessed maternal tobacco and cannabis use by questionnaires. Placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) were measured in the first and second trimester and at delivery from blood samples. Placental weight and pregnancy complications were obtained from medical records. We observed that tobacco use before and during first-trimester only was not associated with any angiogenic factors. As compared to no tobacco use, continued use during pregnancy was associated with higher PlGF, lower sFlt-1 concentrations, and lower sFlt-1/PlGF ratio in second trimester (all p-values
