Increased anxiety symptoms and diabetes are related in older people with ID. This association may be bidirectional. No other associations of depression and anxiety symptoms with cardiovascular risk factors could be proven to be significant. Therefore, more research is needed to unravel the mechanisms of stress, mood disorders and cardiovascular disease in older people with ID. To provide comprehensive care for older people with ID, screening for diabetes and components of the metabolic syndrome in people with anxiety or mood disorders, and screening for symptoms of anxiety or depression in people with diabetes is warranted.
