Authors T1D subjects Healthy population comparison Physical level evaluation methods Physical activity level of young T1D
[101] 6-20 yo Yes Physical activity evaluation by the mother according to 3 levels Physical activity decrease with age, more important in T1D compared to healthy subjects.
[102] Children amd adolescents No Behaviour questionnaire Behaviour with physical activity more negative in T1D adolescents compared to T1D children.
[103] 10-15 yo      
[104] 6-18 yo Yes Descriptive questionnaire. Not quantitative T1D have better adherence to physical activity in gym compared to healthy subjects (40% vs. 27%)
[11]       Patients with the best adherence to training program are the youngest, with a better glycemic control.
[105] ♂ 10.2-16.5yo Yes Physical activity evaluation by the parents according to 5 levels No significant difference compared to healthy controls
[106] N=142; 6-18 yo Yes (n=97 BMI matched) No indication about the Questionnaire used No difference for the time dedicated to sport at school or in competition No difference for the type of physical activity during free time (ball games very present, but time dedicated to them >  inT1D (6.8 h/week vs. 4.6 h/week), in ♀or ♂. Total time spent in a week for physical activity > in T1D.
[107] Children and adolescent <18yo      
[108] ♀ 12-19 yo(Tanner stage 2 -5)     T1D are less involved in physical activity (464 ± 123 vs. 523 ± 138 counts.min-1.j-1, P = 0.06) and are more sedentary (443 ± 60 vs. 390  ± 73 min.j-1, P< 0.005) vs. healthy.
[90] N=17 ♂ prepubescent; 8.5-13yo     No quantitative difference of weekly physical activity (gym, leisure, school) between T1D and healthy.
[27] N=23251; 3-18 yo      
[35] N=138 children et adolescents (5.9-20yo)      
[29] N=2269; 11-18 yo     Older patients and ♀ have less physical activity.
[109] N=240 children  6-10 yo and 483 T1D adolescents from 11 to 19 yo     54% of patients don’t follow recommendations of 60min/day of moderate to high intensity physical activity ♀ less active than ♂ during childhood and adolescence
[110] N=37 children and adolescents     Moderate to high intensity cumulated physical activity = 53.6 min/day in average (< recommendations of 60min/day) Only a few high intensity physical activity (8.3 min/day in average) Physical activities are mostly ≤5min
[37] N=32; 6-17 yo     Total amount of physical activity (Counts) at moderate to high intensity < in T1D vs. healthy
[32] N=203 ♀ 11-19 yo     Physical activity for at least 60min/day for only 2.7 days in average during the last week, and 3.1 days in average during an usual week.
[111] N=384; 10-20 yo     No difference (slight decrease) of physical activity between T1D and healthy. 60% (in average) of T1D have < 1 session of 30min of high intensity physical activity  /day and 20% have < 2 sessions of moderate to high intensity /day (whereas international recommendations are 2 sessions of moderate to high intensity of physical activity a day)
[112] N=48; 5-18 ans     Total physical activity decreased in T1D vs. healthy Only 38.5% of T1D and 60.4% of healthy matched recommendations of 60min/day of moderate to high intensity physical activity
[113] N=129; children     Physical activity comparable between T1D and healthy T1D more involved in team sport
[31] N=19 ♀; <18.5yo; Tanner stages 4-5     Tendancy (NS) for a lower physical activity in gym in T1D (0.7h/week in average) vs. healthy (1.4h/week in average)
[34] N=60; 8-16 yo     No difference in physical activity nor intensity between T1D and healthy.
[72] N=24 children < 7 yo     T1D less active than healthy, present 16min less in moderate to high intensity physical activity Total physical activity (counts/day and min/day) and time spent in moderate to high intensity physical activity < in ♀ vs. ♂
[98] N=35 children prepubescent/peri-pubescent     Total physical activity measured with accelerometer < in T1D vs. healthy whereas physical activity estimated with questionnaire comparable in both groups.
[91] N=106; 8-18 yo     No difference between T1D and healthy
♀: Girls; ♂: Boys; NS: Not Significant
