- To determine their health status, we studied 2,282 Israeli adults with intellectual disability who were at least 40 years of age and lived in residential care. Results showed that age is a significant factor in health status. The frequency of different disease categories (e.g., cardiovascular disease, cancer, and sensory impairments) increased significantly with age for both genders. Cardiovascular disease in this population was less prevalent when compared to the general population, suggesting that underdiagnosis of some diseases or conditions may be prevalent in this population. The patterns of organ-system morbidity with increasing age were similar to those in other studies conducted in several countries, suggesting that health status and outcomes could be independent of cultural factors.
