1 Background Individuals with intellectual disability experience significant health inequities across the life course. Compared with the general population, they have substantially higher rates of physical and mental health conditions, greater multimorbidity and markedly reduced life expectancy (van Schrojenstein Lantman-De Valk et al. 2000; Kinnear et al. 2018; Trollor et al. 2017). In Australia, approximately 2% of the population live with an intellectual disability (Bourke et al. 2024).
