The impact of sport on health status, psychological well-being and physical performance of adults with haemophilia.

BACKGROUND: There is increasing recognition that sport is important for individuals with haemophilia; however, there remains a paucity of data of the importance of this in adults, many of whom already have joint pathology related to childhood bleeds and treatment access. This multicentre, cross-sectional study presents the impact of sport on health-related quality of life (HRQoL), physical performance and clinical outcomes in adults with haemophilia. RESULTS: Fifty adults aged 35.12±14.7 with mild (n = 12), moderate (n = 10), or severe (n = 28) haemophilia A (70%) or B (30%) from four haemophilia centres across the United Kingdom participated in the study. A total of 64% were overweight/obese according to their BMI; median orthopaedic joint scores using the WFH Orthopaedic Joint Score (OJS) were 6 (range 0-48). On a VAS pain scale (range of 0-10), patients reported mean score of 5.66 ± 2.4. 36% of participants reported not doing any sport, mainly due to their physical condition. However, 64% of participants reported undertaking sporting activity including contact sports, mostly twice per week in average 4 h week(-1) . Participating in sport did not have a statistically significant impact on HRQoL; except in the domain 'sport and leisure' of the Haem-A-QoL. Patients doing more sport reported significantly better HRQoL than those doing less sport (P < 0.005). Those doing sport for more than 4 h week(-1) had a significantly better physical performance than patients doing less sport (assessed with Hep-Test-Q). Encouraging physical activity and sport in older patients with haemophilia may have a direct impact on their HRQoL; thus, education about sport activity should be incorporated into routine haemophilia care.

The impact of sport on children with haemophilia.

Sport is nowadays perceived as beneficial for children with haemophilia, as good muscle strength supports joints and may reduce bleed frequency; by contrast psychological benefits are less known. This study introduces the impact of sport on health-related quality of life (HRQoL) and physical performance in children with haemophilia. A cross-sectional, multi-site, study of boys aged 6-17 years with haemophilia A or B of any severity, current or past inhibitor, which assessed physical performance, sporting activity and HRQoL using age appropriate questionnaires including KINDL, Haemo-QoL and HEP-Test-Q. Eighty-four haemophilic boys (23 mild, 19 moderate, 42 severe) with a mean age of 11.52 years (SD = 3.4) were enrolled from two haemophilia centres in the United Kingdom. 28.4% were overweight/obese according to their BMI/age and had a good orthopaedic status (M = 1.55, SD = 3.3). Boys watching < 1-2 h of TV/PC/day had fewer days lost (M = 3, SD = 3.2) than those with a more sedentary lifestyle (M = 9.40, SD = 7.1) (P < 0.032). 90.5% participated in regular sporting activity; 79.9% at least twice a week. HRQoL in children was generally good, with highest impairments in boys aged 8-12 years. Boys aged 8-16 years reported good physical performance (M = 80.0, SD = 16.0) with highest impairments in the dimensions 'endurance' and 'mobility'. Boys doing sport had a significant better physical performance and HRQoL than boys not doing sport. Sedentary life styles had a negative impact on the subjective physical performance and number of days lost of children. Encouraging haemophilic boys to participate in sport will have a direct impact on their overall HRQoL.
