The predictive value of physical fitness for falls in older adults with intellectual disabilities.
In adults with ID aged 50+, past falls and Down syndrome status predict future falls; fitness tests add no extra value.
01Research in Context
What this study did
Oppewal et al. (2014) tracked 724 adults with intellectual disability who were 50 or older. Staff gave each person eight quick fitness tests like walking speed and grip strength. The team then waited to see who fell over the next few years.
They wanted to know if poor fitness scores could flag future falls.
What they found
Before adjusting for other factors, slow walkers did fall more. After adding age, sex, prior falls, and Down syndrome status, only two things mattered: a history of falls and not having Down syndrome. Fitness numbers added no extra warning power.
In short, ask about past falls and Down syndrome first; skip the stopwatch.
How this fits with other research
Oppewal et al. (2014) and Oppewal et al. (2015) used the same Dutch cohort and show fitness predicts later loss of daily-living skills. The current paper narrows the lens to falls and finds fitness fades once you know fall history.
Enkelaar et al. (2013) seems to clash: in mild ID, higher activity and better visuo-motor skills raised fall risk. The difference is ID level. Lotte studied mild-moderate clients who move more; Alyt studied the whole range and adjusted for Down syndrome, washing out the fitness signal.
Spriggs et al. (2015) later showed a frailty index predicts medication use but not falls, backing the idea that simple history questions beat complex scores in this group.
Why it matters
You can trim your fall-risk screen to two quick items: "Any falls in the past year?" and "Does the client have Down syndrome?" If both answers are no and yes, stay alert but do not bank on gait speed or grip gadgets. Spend the saved minutes on balance training or home safety instead.

03Original abstract
A high incidence of falls is seen in people with intellectual disabilities (ID), along with poor balance, strength, muscular endurance, and slow gait speed, which are well-established risk factors for falls in the general population. The aim of this study was to assess the predictive value of these physical fitness components for falls in 724 older adults with borderline to profound ID (≥ 50 years). Physical fitness was assessed at baseline and data on falls was collected at baseline and after three years. Gait speed was lowest in participants who fell three times or more at follow-up. Gait speed was the only physical fitness component that significantly predicted falls, but did not remain significant after correcting for confounders. Falls at baseline and not having Down syndrome were significant predictors for falls. Extremely low physical fitness levels of older adults with ID, possible strategies to compensate for these low levels, and the finding that falls did not increase with age may explain the limited predictive value of physical fitness found in this study.
