Objective: This study evaluates differences in child healthcare utilization by maternal fertility status in the first four years of life. Study design: The retrospective cohort evaluated Massachusetts (MA) live born infants using data linked from clinical assisted reproductive technology (ART) data, birth certificates, and hospital discharge records. Hospital records of infants born 2004–2017 to mothers of fertile (no infertility treatments or indicators of infertility), unassisted subfertile (UF, indicators of infertility but no fertility treatment), medically assisted reproduction (MAR, non-ART assistance with reproduction) and ART treatment were studied. Adjusted relative risk (aRR) was calculated using multivariable log binomial regression models. Results: We included 339,426 singleton live-born infants discharged from birth hospitalization. Compared to children born to fertile mothers, those born to UF, MAR and ART-treated mothers were more likely to have hospital-based care (aRR 1.06–1.21) in their first 4 years. Conclusions: Maternal subfertility with and without treatment was associated with small increases in child healthcare utilization.
