    Abstract:
    OBJECTIVE: The purpose of this study was to describe relations among maternal demographic and lifestyle characteristics and midpregnancy levels of angiogenic markers (soluble Fms-like tyrosine kinase-1, placental growth factor, soluble endoglin). STUDY DESIGN: In a large pregnancy cohort, linear models were used to evaluate relations among maternal characteristics and midpregnancy angiogenic markers with and without covariate adjustment. Associations were examined in a subcohort that included term and preterm deliveries (n = 1302) and among "normal" term pregnancies (n = 668). RESULTS: Concentrations of all factors declined with increasing maternal body mass index. Multiparous women had lower soluble Fms-like tyrosine kinase-1 levels than primiparous women. Higher placental growth factor and slightly lower soluble endoglin levels were observed among women who smoked at enrollment, but not among those women who quit before enrollment. African American women had higher levels of all markers. CONCLUSION: Understanding relations among maternal characteristics and levels of angiogenic factors may improve studies that use these markers to examine etiology and/or to predict adverse pregnancy outcome.
