Bone quality in older adults with intellectual disabilities.

Bastiaanse et al. (2014) · Research in developmental disabilities 2014
★ The Verdict

Nearly half of adults with ID over 50 have low bone quality—screen them early and address modifiable risk factors like BMI and anticonvulsant use.

01Research in Context

01

What this study did

Sawyer et al. (2014) checked bone quality in 768 Dutch adults with intellectual disability. Every person was 50 or older.

The team used a cross-sectional survey. They asked who had low bone quality and what factors came with it.

02

What they found

Almost half, 43.9%, had low bone quality.

Risk flags were female sex, older age, severe ID, trouble walking, anticonvulsant use, and low body weight.

03

How this fits with other research

Day et al. (2021) in Ireland later saw 69% of older adults with ID tipping the scales as overweight or obese. Their data extend the Dutch picture: extra weight links to other chronic woes, yet the Dutch work shows low weight hurts bones.

Lin et al. (2010) found an opposite BMI twist in teens. Heavier adolescents with ID had fewer spinal problems. This looks like a clash, but age explains it. Extra weight stresses young growing bones in good ways; after 50, thin frames simply lack the padding that keeps bones strong.

Kuhn et al. (2022) pooled 16 studies and confirmed poor motor skills hurt bone health. That review backs the Dutch finding that adults who can’t move well end up with weaker bones.

Why it matters

You now know half of your older ID clients may have fragile bones. Add bone-health questions to intake. Watch weight, anticonvulsant scripts, and mobility. A quick referral for a scan or a diet tweak today can prevent a fracture tomorrow.

03Original abstract

Although osteoporosis is a progressive bone disease leading to increased risk of fracture, it has rarely been investigated on a large scale in older people with intellectual disabilities (ID). In this study, 768 persons with ID (aged ≥ 50 years) were measured with quantitative ultrasound to determine the prevalence of low bone quality. The association of low bone quality with patient characteristics, mobility, physical activity, body mass index (BMI), prior fractures, anticonvulsant drug use, intake of calcium, and vitamin D3 levels was also investigated. The prevalence of low bone quality was 43.9%. Low bone quality was positively associated with female gender, age, more severe level of ID, mobility impairment, and anticonvulsant drug use, and negatively with BMI. In clinical practice, people with ID who are at risk for low bone quality should periodically be screened for osteoporosis and be given advice about nutritional supplements and appropriate lifestyle.
