Aims Girls with Type 1 diabetes often gain excessive weight during puberty. The aims of this study were to compare objectively assessed physical activity and energy intake in girls with Type 1 diabetes with those in healthy age‐matched controls. Methods This prospective cohort study comprised 26 girls with Type 1 diabetes and 49 control girls. The mean age of the diabetic girls was 15.7 ± 2.1 years and that of the control girls 15.8 ± 2.1 years. In the diabetic group, mean haemoglobin A 1c was 7.6 ± 1.4% and daily insulin dosage was 1.1 ± 0.3 U/kg. Physical activity was measured during 7 consecutive days with a uniaxial accelerometer, and energy intake was assessed concurrently with a 7‐day food diary. Results There was a tendency towards lower total amount of physical activity in the diabetes group but the difference between the study groups did not reach statistical significance (Diabetes: 464 ± 123 counts/min/day; Controls: 523 ± 138 counts/min/day; P = 0.06). No difference was found between the groups regarding total energy intake (Diabetes: 8.5 ± 1.8 MJ/day; Controls: 8.4 ± 2.6 MJ/day). The carbohydrate intake was lower and the protein and fibre intakes were higher in girls with diabetes. No association was observed between physical activity, energy intake and HbA 1c . Conclusions In this prospective cohort study, we found a tendency towards lower physical activity but no differences in energy intake between girls with Type 1 diabetes and age‐matched controls. Larger studies are needed to further explore the importance of the total amount of physical activity for excessive weight gain in adolescent girls with Type 1 diabetes.
