Reporting from Finland: Maternal T1D, Overweight/Obesity Linked to Heart Defects in Offspring

Maternal type 1 diabetes and overweight and obesity are associated with an increased risk for congenital heart defects (CHDs) among offspring, according to a study published online Jan. 5 in JAMA Network Open.

Riitta Turunen, M.D., Ph.D., from Helsinki University Hospital and the University of Helsinki, and colleagues conducted a nationwide population-based register study in a birth cohort from Finland comprising all children born between 2006 and 2016 (620,751 individuals) and their mothers to examine the association of maternal diabetes and overweight or obesity with CHDs.
