Bone quality in young adults with intellectual disability involved in adapted competitive football.

The objective of this study was to analyse bone quality parameters of football players with intellectual disability (ID) participating in adapted competitive football. Sixty-seven male football players with ID were studied: 22 with Down syndrome (DS) and 45 without DS. The average age was 26 years (range: 16 ̶ 50 years). A group of 25 age-matched sedentary individuals with ID (11 DS and 14 non-DS) and another group of 20 healthy participants of the same age group not involved in competitive football were comparatively analysed. There were no differences in the bone quality parameters when the healthy sedentary individuals were compared with both the sedentary and the football players with ID. However, the speed of sound (SOS), -score, and estimated bone mineral density (BMD) were of higher values in the football players with ID than in the sedentary ID group ( < 0.05). On comparing the football players with non-DS ID with the sedentary non-DS individuals, significant differences were noted in SOS ( < 0.01), -scores ( < 0.01), and estimated BMD ( < 0.01). Four of the 45 non-DS (8.9%) and none of the football players with DS had -scores less than -1.5. Two of the 14 sedentary non-DS participants (14.3%) had -scores indicating osteoporosis. In summary, the ID population actively involved in football showed higher values of bone mass parameters than their sedentary ID and healthy peers. The participants with non-DS ID showed a higher prevalence of osteoporosis than the football players with DS. Participation in sports seems to prevent bone loss in individuals with ID.
