Abstract

The hyperglycemic intrauterine environment has been shown to have long-term effects on offspring. We aimed to evaluate its effect on the long-term risk of childhood malignancies. This was a population-based cohort analysis comparing the risk for long-term childhood malignancies (≤18 years) in children born to mothers with and without gestational diabetes mellitus (GDM). Childhood malignancies were diagnosed by physicians and recorded in hospital medical files according to predefined codes based on ICD-9. Deliveries occurred between the years 1991 and 2014 in a tertiary medical center. Children to mothers with pre-GDM, with fetal congenital malformations, and with benign tumors were excluded from the analysis. Kaplan-Meier survival curve was constructed to compare cumulative oncological morbidity in both groups over time. Cox proportional hazards model was used to control for confounders. During the study period, 236 893 infants met the inclusion criteria; 10 294 (4.3%) of whom were born to mothers with GDM. Hospitalizations involving malignancy diagnoses were comparable between the groups (0.11 vs. 0.12%; P=0.424), as were the cumulative incidences of total oncological morbidity using a Kaplan-Meier survival curve (log-rank P=0.820). In the Cox regression model, maternal GDM was not associated with increased childhood oncological hospitalizations while controlling for maternal age, gestational age, and hypertensive disorders (adjusted hazard ratio: 1.02, 95% confidence interval: 0.58-1.82, P=0.932). Exposure to intrauterine hyperglycemic environment due to maternal GDM does not increase the risk for childhood malignancies.
