There is little literature that explains the relationship between intellectual disability (ID) and physical and sensory disabilities. A review conducted in 1987 indicated increased prevalence of physical health problems amongst people with ID (McLaren & Bryson, 1987). The current classification system used by the International Federation for Para Athletes with Intellectual Disability (INAS) does not take into account any relationship between ID and physical or sensory disabilities . The present study aimed to provide evidence to enable INAS to address the potential inequalities in the classification system and to add to understanding of the relationship between ID and physical and sensory disability. Participants (N=111) were recruited from regional and international sporting events for people with ID. IQ measurements were gained either from records or by administration of an assessment. All participants, with a trusted adult, were administered a semi-structured health interview. Findings indicated a weak negative correlation between IQ and additional physical disability. The data also suggested that level of additional physical disability negatively predicts athletic performance and there is some limited support for the suggestion that IQ positively predicts performance. The findings have implications for INAS and health/social care services.
