Abstract
Background and Objectives
There is a lack of information on intervention strategies employed for health promotion and disease prevention for older adults with intellectual and developmental disabilities (IDD), who usually experience poorer health compared to their peers without IDD. We carried out the first systematic review to scrutinize the impact of intrinsic factors (e.g., cognitive, mental, and physical health, etc.), on health status of older adults with IDD.
Research Design and Methods
To assess the efficacy of such interventions, we examined 23 articles including prospective ‘healthy aging’ interventions designed for adults with IDD. Searches were carried out in the databases Web of Science; Scielo; PsycINFO in April 2020. Articles were organized in thematic areas: (1) Physical activity and health nutrition (n=10); (2) Health education and health screening (n=6); (3) Social inclusion and community participation (n=3); and (4) Multi-components (n=4). Except for five RCT studies, the designs were mainly non-randomized, involving small sample sizes (Nrange = 8 to 379 participants), and lacking follow up.
Results
The studies included 2,398 men and women with IDD (ranging in age from 18 to 86 years [mean age: 44.3 yrs.]). Overall, intervention outcomes were mostly positive, however some negative outcomes were reported.
Discussion and Implications
In brief, healthy aging interventions for people with IDD remain scarce, incipient, and sporadic. We recommend that more attention needs to be given to active health promotion with people with IDD as a program practice among organizations and as a focal public policy among governments.
