Abstract AIMS: Maternal diabetes may affect offspring cognitive function. The objective of the study was to evaluate cognitive function and potential predictors hereof in adult offspring of women with Type 1 diabetes. METHODS: We conducted a follow-up study of adult offspring of women with Type 1 diabetes (n = 158) and a reference group from the background population (n = 118). The main outcome measure was offspring cognitive function measured by global cognitive score, derived from Raven's Progressive Matrices and three verbal subtests from the Weschler Adult Intelligence Scale. RESULTS: Offspring of women with Type 1 diabetes obtained lower global cognitive scores (94.8 vs. 100.0, P = 0.004) than offspring from the background population. When adjusted for confounders, the groups no longer differed significantly (difference 0.4, 95\% CI -3.3 to 4.). Positive predictors of cognitive function in offspring of women with diabetes were family social class, parental educational level, maternal diabetes duration, male gender and offspring age, whereas parity ≥ 1 and gestational age < 34 weeks were negative predictors. We found no association with maternal glycaemia during pregnancy or with neonatal hypoglycaemia. CONCLUSIONS: Impaired cognitive function in adult offspring of women with Type 1 diabetes compared with the background population apparently reflects differences with respect to well-known confounders. However, harmful effects of maternal hyperglycaemia may be mediated through delivery at < 34 weeks. © 2011 The Authors. Diabetic Medicine © 2011 Diabetes UK.
