Aims: To report the results of a case-finding study conducted during a feasibility trial of a supported self-management intervention for adults with mild to moderate intellectual disability and Type 2 diabetes mellitus, and to characterize the study sample in terms of diabetes control, health, and access to diabetes management services and support.
Methods: We conducted a cross-sectional case-finding study in the UK (March 2013 to June 2015), which recruited participants mainly through primary care settings. Data were obtained from medical records and during home visits.
Results: Of the 325 referrals, 147 eligible individuals participated. The participants' mean (sd) HbA1c concentration was 55 (15) mmol/mol [7.1 (1.4)%] and the mean (sd) BMI was 32.9 (7.9) kg/m2 , with 20% of participants having a BMI >40 kg/m2 . Self-reported frequency of physical activity was low and 79% of participants reported comorbidity, for example, cardiovascular disease, in addition to Type 2 diabetes. The majority of participants (88%) had a formal or informal supporter involved in their diabetes care, but level and consistency of support varied greatly. Post hoc exploratory analyses showed a significant association between BMI and self-reported mood, satisfaction with diet and weight.
Conclusions: We found high obesity and low physical activity levels in people with intellectual disability and Type 2 diabetes. Glycaemic control was no worse than in the general Type 2 diabetes population. Increased risk of morbidity in this population is less likely to be attributable to poor glycaemic control and is probably related, at least in part, to greater prevalence of obesity and inactivity. More research, focused on weight management and increasing activity in this population, is warranted.
