Background: There is little research comparatively assessing prevalence of pain between older people either with or without intellectual disability. This paper explores health and social factors associated with chronic pain in these two groups. Method: A cross-sectional survey was undertaken in New South Wales and Queensland, Australia. Inclusion criteria were adults either with or without intellectual disability, aged 60 years and older, and currently living in community-settings. Univariate and multivariable analyses were undertaken on a sample of 391 adults with intellectual disability and 920 adults without intellectual disability. Results: Key findings included higher prevalence of pain in the intellectual disability group, along with higher rates of osteoarthritis, falls, oral health problems, and mood disorders. Conclusions: Mitigating risk factors for conditions that cause chronic pain in older adults is crucial. As longevity increases, the healthcare sector needs to prioritise chronic pain management for people with intellectual disabilities through appropriate treatment strategies.
