Background: Although sports participation in Dutch people with haemophilia (PWH) is similar to the general population (GP), sports injury data have not been compared to the GP.

Aims: To assess sports injuries in PWH according to severity and compare them to the general population.

Methods: Sports injury data and bleeds following sports injuries were prospectively collected for 12 months in PWH aged 6-49 without inhibitors who played sports at least once weekly. National GP data was collected retrospectively with a 3 month recall period. Data on 12-months’ Sports injuries in PWH were compared according to severity and 3-months’ data were compared to the GP. Groups were compared using non-parametric methods.

Results: Data from 125 participants aged 6-49 (41 children, 90% haemophilia A; 54% severe, 91% severe on prophylaxis) were included. Eighty-seven sports injuries were reported by 51 participants. Participants with severe haemophilia reported more sports injuries than those with non-severe haemophilia (69% vs. 31%; p< 0.01), but a shorter time loss after injury (median 7 (IQR: 3-19) vs. 14 (7-25) days; p=0.05). Injuries reported by PWH were evenly distributed across the annual seasons (summer, autumn, winter, spring; p=0.25). PWH reported a similar number of sports injuries as the GP (18% (CI: 12-25%) vs. 16% (14-18%)) over 3-month’ periods, but a higher injury rate (6.0 vs. 3.4 injuries/1000 hrs exposure). Both PWH and GP mostly reported lower extremity injuries (PWH: 66%; GP: 62%).

Conclusion(s): These results showed different sports injury patterns in severe and non-severe haemophilia. This could indicate a tendency of participants with severe haemophilia to be more prone to report their sports injuries (reporting bias), or increased risk-taking by participants with non-severe haemophilia. Furthermore, injury risk was similar in PWH and GP, suggesting that sustaining injuries occurred independent of haemophilia.
