Background: Uterine fibroids are a common morbidity in women and its prevalence is increasing with age. As maternal age rises, fibroids become more prevalent during pregnancy. Aim: To assess perinatal outcome and long-term health of children to mothers with uterine fibroids during pregnancy. Study design: A population-based cohort analysis assessing long-term hospitalizations of offspring, up to the age of 18 years, due to gastrointestinal, neurological, cardiovascular, endocrine, and respiratory morbidity, following pregnancies diagnosed with and without a fibroid uterus. Multivariable generalized estimating equation (GEE) analysis adjusted for maternal clusters and other possible confounders was performed. Kaplan-Meier survival curves and Cox survival regression models were used to compare cumulative morbidity incidence and control for confounders. Subjects: All singleton deliveries occurring between 1991 and 2014. Outcome measures: Perinatal outcome and long-term pediatric morbidity. Results: A total of 242,445 singleton deliveries were included; 0.5% of which were diagnosed with uterine fibroids (n = 1237). In the GEE multivariable analyses, advanced maternal age, hypertensive disorder and diabetes mellitus, fetal growth restriction, low birthweight (<2500 g), and small for gestational age newborns, were all independently associated with uterine fibroids during pregnancy. Hospitalizations up to the age of 18 years in the different health categories were comparable between the groups, using Cox regression models, controlled for clinically significant confounders in the long-term outcomes. Conclusion: Maternal uterine fibroids appear to negatively impact perinatal outcome, mainly fetal growth. However, no independent major impact on future health of the offspring can be detected.
