Prevalence of low bone density in women with developmental disabilities.
This study was designed to assess the prevalence and severity of low bone mineral density in an institutionalized population of postmenopausal women (n = 79) with developmental disabilities, using quantitative ultrasound of the calcaneus. The results demonstrate that this population has a significantly lower quantitative ultrasound index (QUI) of the calcaneus compared with a referent population of age-matched control subjects without mental disabilities. We used the QUI T-score threshold of <-2.0 standard deviations (SDs) to define individuals at high risk for osteoporosis, and 82% of the study participants met this criterion. Furthermore, approx 43% of the population had a heel QUI that was more than 2 SDs below that of age-matched control subjects, consistent with a severe degree of demineralization.
