Osteoporosis and intellectual disability: is there any relation?

One of the causes of osteoporosis is immobility. The present study examined osteoporosis in 23 bedridden adults with intellectual disability. It was found that the bone mineral density of the subjects was low, even though their calcium intake was more than adequate. Vertebral and other fractures were concentrated mainly in the elderly subjects (> 50 years). Very low vitamin D levels were also found in the subjects despite good nutritional levels. It is concluded that people with intellectual disability and mobility disorders are at risk of metabolic bone disease.
