Diabetes is one of many chronic diseases that people with intellectual disability share with others in the general community (Goldacre, Wotton, Seagroatt, Yeates, & Reading, 2005). People with intellectual disability also often have specific disorders associated with the syndrome and they experience barriers to accessing healthcare services including communication difficulties and devaluing. Consequently, they have poorer health (Beange, McElduff, & Baker, 1995).
