A 35-year follow-up study based on a nation-wide population study of the life expectancy of people with intellectual disability (ID) was undertaken. The study population consisted of a total of 60,969 person-years. A prospective cohort study with mortality follow-up for 35 years was used and the life expectancy of people with ID was calculated for different levels of intelligence. Proportional hazard models were used to assess the influence of level of intelligence and associated disorders on…

Cause-specific mortality of people with intellectual disability in a population-based, 35-year follow-up study.

Cause-specific mortality in people with intellectual disability differed significantly from the general population, with reduced mortality from neoplasms and external causes, but ageing individuals with mild ID had similar mortality patterns to the generalpopulation.

The influence of intellectual disability on life expectancy.

A study of trends in the survival profiles of people with intellectual disability in Western Australia indicates a major and expanding increase in the service requirements of this aging, intellectually disabled population during the past two generations.

The Life Expectancy of People with Intellectual Disabilities in Germany.

Comparing the results with other international studies, the trend of increasing life expectancies of people with intellectual disabilities is confirmed and people with Intellectual disabilities still have a lower average life expectancy than the general population.

Mortality and Life Expectancy in Dutch Residential Centres for Individuals with Intellectual Disability, 1991–1995

Due to prolonged longevity, the client population in residential centres will continue to age and thus the numbers of older individuals will increase and this ageing process has implications for the care for elderly individuals, because they need other care than before due to physical, psychological and social changes and spiritual challenges.

The incidence of cancer in people with intellectual disabilities

The age-standardised incidence of all cancers in people with ID was not significantly different from the general population, however, males with ID were observed to have a significantly increased risk of leukaemia, brain and stomach cancers, and a reduced risk of prostate cancer, while leucaemia, corpus uteri and colorectal cancers were significantly higher in females.

The elderly with intellectual disability and mental disorder: a challenge for old age psychiatry

Women who have mild intellectual disability not due to Down's syndrome, who are ambulant and self caring, have the longest life expectancies, whilst men and those with greater levels of disability have lower life Expectancies.

With the exception of people with severe and multiple disabilities or Down syndrome, the life expectancy of this group now closely approximates with that of the general population.

Withholding treatment and intellectual disability: Second survey on end-of-life decisions in Switzerland

The results have implications on surrogate decision-making for people with ID living in residential homes in Switzerland as the study partly confirms the results of previous studies, and further studies will be necessary.

Trends in age-standardised mortality rates and life expectancy of people with learning disabilities in Sheffield over a 33-year period

There was a sustained reduction in age-standardised mortality rates and a sustained increase in life expectancy for people with intellectual disabilities over the 33-year period, similar to those observed in the general population of England and Wales.

The prevalence of intellectual disability among 1-year cohorts of Finnish elderly as determined with the multiple register method

The new estimate for the prevalence of ID among the elderly in Finland is higher than those previously published, but congruent with the increasing life expectancy of elderly persons with ID.

The life expectancy of profoundly handicapped people with mental retardation.

Severe mental retardation is associated with a decrease in life expectancy, particularly for those who were immobile, and mobile subjects were found to have a much shorter life expectancy than those who could move about.

Life expectancy of mentally retarded persons in Canadian institutions.

Data obtained from Statistics Canada were presented on the mortality level and expectancy of life for profoundly retarded and severely and moderately retarded persons in Canadian institutions for the

Mortality, life expectancy and causes of death of mildly mentally retarded in Denmark.

For males of the age 15-64 an excess mortality of malignant neoplasms, of diseases of the respiratory system, of congenital malformations, and of accidents were found, and for females the pattern was less significant.

Life expectancy in Down syndrome.

This study studied 1341 patients with Down syndrome identified by the British Columbia Health Surveillance Registry from more than one million consecutive live births from 1952-1981 inclusive to indicate that life expectancy is much better than generally believed.

Mortality in the mentally handicapped: a 50 year survey at the Stoke Park group of hospitals (1930-1980).

There has been a marked change in the causes of death during this period, with increased longevity in the mentally handicapped, in particular in those with Down's syndrome whose longevity has increased by 40 years, and over 30 years in others.

Long-term prognosis of seizures with onset in childhood.

Although the majority of patients with epilepsy in childhood are free of seizures by the time they become adults, they are at increased risk for social and educational problems and patients whose epilepsy does not remit also have an increased risk of death.

Age-specific standardized mortality rates in people with learning disability.

It was found that SMRs tended to be raised for both males and females in each population, but SMRs do not always significantly differ from unity.

External causes of death among persons with developmental disability: the effect of residential placement.

Comparisons between different residential settings found persons in semi-independent living had significantly higher risk than did those in their family home or group homes, with homicides rates being three times higher and pedestrian accidents rates being doubled, while persons in institutions had much lower risks with respect to most causes.

Demographic and epidemiological determinants of healthcare costs in Netherlands: cost of illness study

The main determinants of healthcare use in the Netherlands are old age and disabling conditions, particularly mental disability, and this cost will inevitably increase further in an ageing population.


Survival rates for persons with cerebral palsy were calculated using information front a population‐based registry which has been collecting data since 1952. The 30‐year survival rate approximates 87
