Association of preconception paternal health on perinatal outcomes: analysis of U.S. claims data

To assess whether paternal health is associated with maternal peripartum and neonatal outcomes. Retrospective cohort study. University research departments. Analytic sample of children born to paired fathers and mothers covering live births within the United States between 2009–2016. Paternal health status (e.g., metabolic syndrome diagnoses, individual chronic disease diagnoses). Primary outcome of preterm birth (i.e., live birth before 37 weeks), and secondary outcomes of low birth weight, neonatal intensive care unit (NICU) stay, gestational diabetes, preeclampsia, eclampsia, and length of maternal stay. The IBM Marketscan Research database covers reimbursed health care claims data on inpatient and outpatient encounters who are privately insured through employment-sponsored health insurance. We assessed 785,809 singleton live births, with 6.6% born preterm. The presence of paternal comorbidities was associated with higher odds of preterm birth, low birth weight (LBW), and NICU stay. After adjusting for maternal factors, fathers with most or all components of the metabolic syndrome had 19% higher odds of having a child born preterm (95% CI 1.11–1.28), 23% higher odds of LBW (95% CI 1.01–1.51), and 28% higher odds of NICU stay (95% CI 1.08–1.52). Maternal morbidity (e.g., gestational diabetes or preeclampsia) was also positively associated with preconception paternal health. Increased preconception paternal comorbidity may be associated with negative infant and maternal outcomes. Although the paternal effect remains modest, these findings highlight the importance of the health of both parents, particularly the mother, on healthy pregnancy. Asociación entre la salud preconcepcional del varón sobre los resultados perinatales: estudio de datos de solicitudes de reembolso en EE.UU Evaluar si la salud del varón está asociada con los resultados maternos periparto y neonatales. Estudio de cohorte retrospectiva. Departamentos de investigación universitarios. Muestra analítica de hijos nacidos de padres y madres emparejados que cubre los nacimientos en Estados Unidos entre 2009 y 2016. Estado de salud de los progenitores (e.g. diagnóstico de síndrome metabólico, diagnósticos de enfermedades crónicas individuales). Resultado primario: nacimiento pretérmino (i.e. nacido vivo antes de la semana 37) y resultados secundarios: bajo peso, estancia en unidad de cuidados intensivos neonatales (NICU), diabetes gestacional, preeclampsia, eclampsia y duración de la estancia m
