Osteoporosis and intellectual disability: is there any relation?

Wilkinson et al. (1998) looked at bone health in adults with intellectual disability who could not walk.

They checked vitamin D blood levels, calcium intake, and bone density. They also counted past broken bones.

Even though the adults drank plenty of milk, their vitamin D was very low.

Their bones were thin and many had already suffered fractures.

Silverman et al. (1994) warned that older adults with ID face the same age-related illnesses as other seniors, including brittle bones. The new data confirm that warning.

Beaulieu et al. (2013) found poor diet quality in overweight adults with ID, yet M et al. show adequate calcium intake. The two studies look at different nutrients—Lauren at overall diet, M at vitamin D—so together they flag a full nutrition check, not just calories.

Bartlo et al. (2011) show exercise strengthens adults with ID. M et al. add a reason to move: weight-bearing activity may protect bones when vitamin D is low.

If you support non-ambulatory adults with ID, do not trust good calcium intake alone. Ask the doctor for a vitamin D screen and a bone-density scan. Simple additions—safe sunlight exposure, fortified drinks, or a vitamin D supplement—can cut fracture risk and pain.
