MVPA in children/adolescents with chronic disease appear to be well below guideline recommendations , although comparable with activity levels of their healthy peers except for children with malignancies .
CONTEXT Moderate-to-vigorous physical activity ( MVPA ) and sedentary time ( ST )  are important for child and adolescent health .
OBJECTIVE To examine habitual levels of accelerometer measured MVPA and ST  in children and adolescents with chronic disease , and how these levels compare with healthy peers .
Physical activity and energy intake in adolescent girls with Type 1 diabetes.
AIMS Girls with Type 1 diabetes often gain excessive weight during puberty . The aims of this study were to compare objective ly assessed physical activity  and  energy intake  in girls with Type 1 diabetes with those in healthy age-matched controls . METHODS This prospect i ve 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 A1c 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 HbA1c . CONCLUSIONS In this prospect i ve 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
