Abstract

Objective: The objective of the study was to investigate whether maternal history of recurrent pregnancy loss (RPL) is associated with offspring childhood ophthalmic morbidity. Method: A hospital-based cohort analysis comparing long-term offspring ophthalmic morbidity in women with and without a history of RPL was performed. Ophthalmic morbidity included hospitalizations involving a pre-defined set of ICD-9 codes. Offspring with congenital anomalies, perinatal mortality cases, and multifetal pregnancies were excluded from the analysis. Cumulative morbidity incidence was compared using Kaplan-Meier survival curves, and the risk of long-term ophthalmic morbidity was assessed by Cox proportional hazards model after adjustment for confounders. Results: During the study period, 242,187 newborns met the inclusion criteria; 5% (12,182) of them were offspring born to mothers with a history of RPL. Ophthalmic morbidity was significantly more common in the RPL group (1.3% vs 0.9%, p <.001, Kaplan-Meier log-rank p <.001). Adjustment for confounders, such as maternal age, gestational age, hypertensive disorders, and maternal diabetes, using Cox regression found that being born to a mother with RPL was independently associated with long-term ophthalmic morbidity (adjusted HR 1.35, 95% CI 1.15-1.59, p <.001). Conclusion: Being born to a mother with RPL is independently associated with an increased risk of ophthalmic morbidity.
