title: Comparison of physical activity and sedentary behaviours between young haemophilia A patients and healthy adolescents.
abstract: In recent studies, adolescent haemophilia A patients and healthy adolescents have been encouraged to participate in physical activity (PA) based on its many established health benefits. However, none of the studies to date has used objective measures of PA and sedentary behaviour. The aims of the current study included: (i) to determine the amount and intensity of habitual PA among haemophilia A and healthy adolescents, and in haemophilia A patients with and without bleeding episodes in the previous year, and (ii) to identify the type and determine the time spent in sedentary activities in which both groups participate to obtain a broadened view of their daily activities. A total of 41 adolescent haemophiliacs and 25 healthy adolescents, between the ages of 8 and 18 years, participated in this cross-sectional study. A triaxial accelerometer was used to measure PA and the Adolescent Sedentary Activity Questionnaire to assess sedentary behaviours among members of both groups. Adolescent haemophilia A patients showed a higher daily mean time engaged in light, moderate and moderate-to-vigorous PAs relative to their healthy counterparts (P < 0.001). Patients who had experienced bleeding episodes during the previous year also spent more time participating in vigorous PAs than healthy adolescents (P = 0.002). With regard to sedentary behaviours, healthy adolescents spent more time listening to music than haemophilia A adolescents (P = 0.003), whereas haemophilia A adolescents spent more time watching TV (P < 0.001) and playing videogames (P = 0.003) than healthy counterparts. Findings suggest that increased participation in moderate intensity PAs and reduced sedentary behaviours should be recommended among adolescents with haemophilia A.
