The prevalence and general health status of people with intellectual disabilities and autism co-occurring together: a total population study.

This is the first study to report the population prevalence of coexisting intellectual disabilities and autism, and the substantial influence this double disadvantage has on general health status, apparent across the entire life course. This highlights a group in need of wider recognition for whom resources should be focused on and planned for, informed by evidence. Staff in services for people with either of these conditions need to be trained, equipped, resourced and prepared to address the challenge of working for people with this duality. This is essential, to address these substantial health inequalities.
