Abstract
To assess physical Aim:  activity and fitness levels of young people with Type
1 diabetes compared with siblings without diabetes, and to investigate the
association between physical activity, physical fitness and glycaemic control
(HbA(1c) ) in The study consisted those young people with diabetes. Methods:
of 97 young years (62% male) from a Paediatric Diabetes people aged 8 to 16
Service in 1 South West England. Sixty participants (67% male) had Type
diabetes and 37 participants (54% male) were siblings without diabetes (control
group). We measured weight, height and waist circumference, calculated BMI and
waist-height ratio and recorded pubertal status, blood pressure and current
insulin regimen information. We assessed physical activity by accelerometry,
from which we calculated light and moderate-to-vigorous intensity activity. We
measured physical fitness by multistage sub-maximal bicycle ergometer test. We
There were no obtained HbA(1c) by venipuncture. Results: differences between
the young people with diabetes and siblings without diabetes in body
composition, blood pressure, physical activity and fitness. Moderate-to-
vigorous physical activity was associated with better glycaemic control,
0.295-0.374) of the variance for = accounting for 30-37% (R(2) HbA(1c) .
 Physical fitness was not associated with HbA(1c.) Conclusions: Moderate-to-
vigorous physical activity was associated with better glycaemic control while
fitness was not. Findings suggest that developing strategies to increased
moderate-to-vigorous physical activity may prove an effective method of
improving glycaemic control in young people with diabetes. ? 2012 The Authors.
