Summary

The study aims to describe physical activity (PA) levels in young people with haemophilia A in Norway compared with non-haemophilia controls, and to identify factors influencing PA. This will be conducted through an observational study measuring PA over 12 weeks. Forty young people with moderate and severe haemophilia A will be enrolled. PA data will be compared to demographically and seasonally matched non-haemophilia controls. PA will be measured using the activity tracker Fitbit Charge 3. A subgroup of participants will also wear the hip-worn accelerometer ActiGraph GTX+BT for seven consecutive days in order to validate the two devices against each other.
