Injuries, falls and accidents among adults with intellectual disabilities. Prospective cohort study.

Finlayson et al. (2010) · Journal of intellectual disability research : JIDR 2010
★ The Verdict

Adults with ID face high injury rates—screen for epilepsy and incontinence, and note Down syndrome as a fall buffer.

✓ Read this if BCBAs and RBTs serving community adults with intellectual disability.
✗ Skip if Clinicians who only work with children or mild ASD without ID.

01Research in Context

01

What this study did

Van der Molen et al. (2010) followed 511 Irish adults with intellectual disability for one full year. They counted every injury, fall, and accident that needed medical care.

The team wanted to know who gets hurt most. They checked age, sex, Down syndrome, epilepsy, and incontinence.

02

What they found

One in five adults had at least one injury. One in eight had a fall that caused harm.

Epilepsy raised the risk of any injury. Incontinence raised the risk of falls. Down syndrome lowered fall risk.

03

How this fits with other research

McCarron et al. (2022) show the same Irish cohort can stay in studies for over a decade. This gives us confidence the injury numbers are stable.

Takenoshita et al. (2026) extend the Down story. They find adults with Down syndrome face high dementia risk, yet J et al. show these same adults fall less. The two papers together tell us Down syndrome brings both protection and risk.

Tyrer et al. (2009) and Morad et al. (2007) use the same risk-factor method for heart disease and constipation. J et al. repeat the recipe for injuries, proving the method works across health problems.

04

Why it matters

You can spot high-risk clients in seconds. Flag epilepsy or incontinence on intake. Add extra safety plans like clutter checks, non-slip shoes, or seizure pads. Praise teams when a Down syndrome client stays fall-free—the data say it is expected. Share the numbers with families to show why these steps save pain and cost.

03Original abstract

BACKGROUND: Injuries are among the leading causes of death and disability in the world and a major public health concern. Falls are a common cause. Young persons with intellectual disabilities (ID) have a higher rate and different pattern of injuries than the general population, but little is known regarding adults. METHODS: The aim of this study was to determine the incidence and types of injuries experienced by a community-based cohort of adults with ID (n = 511) in a 12-month period. Face-to-face interviews were conducted with participants 2 years after they had first been recruited into a longitudinal study. RESULTS: Incidence of at least one injury in a 12-month period was 20.5% (105), of which 12.1% (62) was because of falls. Incident injury was predicted by having epilepsy and not having autism. Incident fall injury was predicted by urinary incontinence, while Down syndrome reduced risk. CONCLUSIONS: Adults with ID do experience a higher rate of injuries and falls when compared with the general population. The results of this study highlight this, and hence the need to work towards the development of interventions for injury and falls prevention in this population.
