Injury risk in young people with intellectual disability

Epidemiological studies have established injury as a major public health problem for young people in the general population, but minimal population-based injury information exists on those with intellectual disability (ID). The present study investigated risk factors for injury to subjects in the Australian Child and Adolescent Development (ACAD) programme, which is examining emotional and behavioural problems in young people with ID. Extensive biopsychosocial data for the ACAD programme were collected at two time intervals (i.e. 1990-1991 and 1995-1996). Carer report of medically attended injury over one year was collected for the first time period (1995-1996) on a sample of 465 ACAD subjects (aged 5-29 years) representative of young people with ID (IQ < 70) to determine risk factors for injury using the ACAD biopsychosocial data. Psychopathology [odds ratio (OR)=3.4] epilepsy (OR = 2.4) and an overly sociable temperament (OR=2.2) are associated with injury in young people with ID. Social and family factors had minimal influence on injury risk in this population. Those who are highly disruptive, self-absorbed, anxious, have problems relating socially, have communication disturbance or have attention deficit hyperactivity symptoms are particularly at increased risk for injury. The present study demonstrates a largely under-recognized public health problem of a high unintentional injury risk for young people with ID, and identifies substantial and important risk factors for injury. Injury prevention programmes, with a particular focus on those with highly disturbed behaviours or epilepsy, are warranted in this population.
