Overweight and obesity amongst Down's syndrome adults.

Prasher (1995) · Journal of intellectual disability research : JIDR 1995
★ The Verdict

Nearly every adult with Down syndrome is overweight or obese, with housing setting influencing the numbers, yet standard metabolic risks do not always follow.

✓ Read this if BCBAs serving adults with Down syndrome in residential or day programs.
✗ Skip if Clinicians who work only with young children or ASD without Down syndrome.

01Research in Context

01

What this study did

The team weighed 201 adults with Down syndrome. They noted who lived in family homes and who lived in staffed houses.

The goal was to see how many people were overweight or obese and if housing mattered.

02

What they found

Almost half of the men and women were obese. Another quarter were simply overweight.

People in family homes carried more extra pounds than people in supervised settings.

03

How this fits with other research

Rasing et al. (1992) saw the same high numbers three years earlier, so the problem is not new.

Kovačič et al. (2020) later showed that Down syndrome carries the highest obesity rate of all developmental disabilities, making our group the top priority.

McQuaid et al. (2024) adds a twist: in Down syndrome, extra weight does not raise blood sugar or cholesterol the way it does in other adults. The scale still matters, but metabolic labs may fool you.

Kittler et al. (2004) tracked the same adults as they aged and found weight drops when Alzheimer’s begins, so lifelong monitoring is key.

04

Why it matters

You now know that obesity is the norm, not the exception, for adults with Down syndrome. Check BMI at every visit and note the living arrangement. If the client lives with family, add nutrition coaching for caregivers. If weight falls later in life, screen for dementia. These simple steps keep you ahead of predictable changes.

03Original abstract

Two hundred and one individuals with Down's syndrome were assessed for evidence of overweight and obesity. Thirty-one per cent of males and 22% of females were overweight, while 48% males and 47% females were obese. Overweight and obesity was significantly associated with living in the family home compared to supervised community units or in hospital. No association with the degree of learning disability was found.
