Background: Falls are common among people with intellectual disabilities. Many falls happen within the home. Our scoping review aimed to identify evidence for falls-risk factors and falls-prevention interventions for this population. Method: We conducted a multi-database search to identify any type of published study that explored falls-risk factors or falls-prevention interventions for people with intellectual disabilities. Following a process of (i) title & abstract and (ii) full-text screening, data was extracted from the included studies and described narratively. Results: Forty-one studies were included. Risks are multifactorial. There was limited evidence of medical, behavioural/psychological, or environmental interventions to address modifiable risk factors, and no evidence of the interventions' cost-effectiveness. Conclusions: Clinically and cost effective, acceptable and accessible falls-prevention pathways should be available for people with intellectual disabilities who are at risk of falls from an earlier age than the general population.
