Heldarskard GF, Spangmose AL, Henningsen AKA, et al. - In this cohort study, researchers evaluated academic performance by grade point average (GPA) in children aged 15–16 years at compulsory school graduation, comparing offspring exposed to GDM (O-GDM) with offspring from the background population (O-BP). Between 1994 and 2001, all singletons born in Denmark (O-GDM: n = 4,286; O-BP: n = 501,045) were analyzed. According to the results, O-GDM had a GPA of 6.29, whereas O-BP had a GPA of 6.78. Academic performance was marginally lower in O-GDM than in O-BP. This difference, however, is unlikely to be clinically significant.
