AIM: To evaluate intellectual outcome, motor skills and anthropometric data of children with congenital hypothyroidism (CH). METHODS: Children with permanent CH who were born in 1999 in Bavaria were eligible for this prospective, population-based study. Cognitive performance was evaluated by the Kaufman Assessment Battery for Children and motor skills were assessed by the motor test, Motoriktest für vier-bis sechsjahrige Kinder (MOT) 4-6. RESULTS: Eighteen of 21 eligible children participated (86%). Median age of the children was 5.5 years (range 4.9-5.8). Treatment with levothyroxine was started after a median of 7.2 days (range 4-15) with a median dose of 12.0 microg/kg (range 7.2-17.0). Mean intelligence quotient (IQ) of the children was 100.4 (standard deviation [SD] 10.1): no children had IQ values below the normal range. Reactivity and speed of movement were significantly reduced in children with CH. Children with an initial thyroid-stimulating hormone (TSH) value of >200 mU/L performed significantly worse than children with TSH value of <or=200 mU/L (p=0.003). Children with CH had a significant increased risk for overweight (risk ratio [RR] 3.91, 95% confidence interval [CI] 1.22-11.75, p=0.005) compared to the Bavarian reference children. CONCLUSION: In this study, children with CH had an increased prevalence of overweight compared to reference data. Partially impaired motor skills could be shown, whereas the intellectual development was normal.
