Black Father's Influence on Adverse Pregnancy Outcomes in the United States: A Narrative Synthesis of Literature.

Few studies have investigated paternal characteristics in relationship with adverse pregnancy outcomes, and results are inconsistent. The purpose of this study was to review studies examining associations between characteristics of Black fathers and adverse pregnancy outcomes in the United States. A systematic narrative synthesis was conducted of research studies examining paternal characteristics of Black fathers in association with adverse pregnancy outcomes: preterm birth, hypertensive disorders of pregnancy, gestational diabetes, spontaneous abortion, and maternal mortality. Seven databases (Academic Search Premier, CINHAL, CENTRAL, ClinicalTrials.gov, Embase, PubMed, and Web of Science) were searched for original research articles from inception to February 2023. Articles were excluded if they (a) were in a language other than English, (b) did not describe original research, (c) included a geographic region outside of the United States, (d) did not include adverse maternal outcomes as a study outcome, (e) did not describe race of fathers in the study sample, and (f) did not describe a paternal characteristic of Black fathers. The search resulted in 210 articles. Six studies were included in the final review; five studies examined associations between paternal characteristics of Black fathers and preterm birth, finding significantly increased odds of preterm birth among births with Black fathers. Among births with non-Hispanic Black paternity, the odds of hypertensive disorders of pregnancy were reduced or not significantly associated. Researchers should continue to explore paternal factors that influence pregnancy outcomes in racial/ethnic-specific models to identify optimal intervention strategies to improve disparities in maternal and child health outcomes.
