Aims/hypothesis: Our aim was to test the hypothesis that gestational diabetes mellitus (GDM) in mothers is associated with poorer cognitive ability in their offspring in India.
Methods: During 1997 to 1998 maternal GDM status was assessed by OGTT at 30?±?2 weeks of gestation. Between 2007 and 2008, at a mean age of 9.7 years, 515 children (32 offspring of GDM mothers [ODM]; 483 offspring of non-GDM mothers [controls]) from the Mysore Parthenon birth cohort underwent cognitive function assessment using tests from the Kaufman Assessment Battery for Children—Second Edition and additional tests measuring learning, long-term storage/retrieval, short-term memory, reasoning, attention and concentration, and visuo-spatial and verbal abilities.
Results: Compared with controls, ODM scored higher in tests for learning, long-term retrieval/storage (p?=?0.008), reasoning (p?=?0.02), verbal ability (p?=?0.01), and attention and concentration (p?=?0.003). In multiple regression, adjusted for the child’s age, sex, gestation, neonatal weight and head circumference, maternal age, parity and BMI, and the parent’s socioeconomic status, education and rural/urban residence, this difference remained significant only for learning, long-term retrieval/storage (??=?0.4 SD (95% CI 0.01–0.75); p?=?0.04) and verbal ability (??=?0.5 SD (95% CI 0.09–0.83); p?=?0.02), and not with other test scores.
Conclusions/interpretation: In this population of healthy Indian children, there was no evidence of lower cognitive ability in ODM. In fact some cognitive scores were higher in ODM.
