Description of intervention(s) / exposure
Physical activity will be measured in secondary school students with type 1 diabetes attending the John Hunter Children's Hospital and their eligible siblings without type 1 diabetes. GT3X+ accelerometers will be utilised to measure physical activity and will be worn on the non-dominant wrist of the child continuously over 7 days. The accelerometers will be collected at the end of the 7 days. Dexcom G6 Continuous glucose monitors will be used to collect interstitial glucose levels for the 7 days of the study, with a new sensor inserted on day 1 of the study.

Not applicable
Comparator / control treatment
The mean daily MVPA (moderate to vigorous physical activity) of secondary students with type 1 diabetes will be compared to published age-matched data. The data will be derived from results from the Physical Activity 4 Everyone Study (PA4E1) conducted by Hunter New England Population Health during March-June 2012. The main comparison to be made is between participants with type 1 diabetes and the published data from the PA4E1 study. Siblings without diabetes will only be compared to study participants with type 1 diabetes.
