Association between maternal gestational diabetes mellitus and high-sensitivity C-reactive protein levels in 8-year-old children: The Yamanashi Adjunct Study of the Japan Environment and Children's Study (JECS).

Gestational diabetes mellitus (GDM) is one of the most common pregnancy-related complications; it is associated with adverse pregnancy outcomes and metabolic disorders in offspring, consistent with the concept of the developmental origins of health and disease. This cohort study of women without diabetes (n = 761), who were part of the Yamanashi Adjunct Study of the Japan Environment and Children's Study, aimed to explore the associations between maternal GDM and their offspring's level of high-sensitivity C-reactive protein (hsCRP), a biomarker of inflammatory and cardiovascular diseases. We analyzed the associations between GDM and the offspring's hsCRP levels using a multiple logistic regression model. A mother with GDM significantly increased the risk for high hsCRP level by 4.07-fold (≥2.0 mg/L) in the child. As such, maternal GDM was significantly associated with increased serum hsCRP levels in 8-year-old children.
