Correlates of bone mineral density in elderly women living in nursing homes for the disabled in Japan

Characteristics of bone aging in the institutionalized elderly are not well known. The aim of this study was to determine the factors correlated with the forearm bone mineral density (BMD) in elderly women with disability. Of 175 female residents living in nursing homes for the disabled in Niigata,...

Description
Summary:Characteristics of bone aging in the institutionalized elderly are not well known. The aim of this study was to determine the factors correlated with the forearm bone mineral density (BMD) in elderly women with disability. Of 175 female residents living in nursing homes for the disabled in Niigata, Japan, 119 agreed to participate and underwent medical examinations in 1999; 107 (age range, 66-100) met our inclusion criteria. We measured forearm BMD by dual-energy X-ray absorptiometry (DXA), and the serum concentrations of 25-hydroxyvitamin D3, 1,25-dihydroxyvitamin D3, intact parathyroid hormone, albumin, total protein, and creatinine. Body weight, score of activities of daily living, and history of femoral neck fractures were also recorded. Forearm BMD decreased with age, and the regression equation was BMD=0.9035exp (-0.0179Age) (R2=0.170, p
