Abstract
UNLABELLED: Unipedal standing time was shorter and bone mineral density was lower in Japanese women aged 50 years and over with low-energy distal radius fractures resulting from falls than those in age-matched community-dwelling Japanese women without distal radius fractures. INTRODUCTION: The aim of this study was to compare unipedal standing time and bone mineral density (BMD) of women >or=50 years of age with distal radius fractures with those of age-matched women without fractures. METHODS: Fracture group was 54 Japanese women with low-energy distal radius fractures resulting from fall. Non-fracture group was 52 community-dwelling Japanese women without fractures. Unipedal standing time and BMD were measured. RESULTS: There were no significant differences in age and body mass index between the two groups. The percentage of women with unipedal standing time <15 s was 44.4% in the fracture group and 13.5% in the non-fracture group, while the respective frequencies for >120 s were 20.4% and 50.0%. The T-score of BMD was significantly lower in the fracture than non-fracture group. Logistic regression analysis identified unipedal standing time <15 s and T-score <70% as significant factors associated with distal radius fractures. Notably, T-score <70% was significant in subjects <65 years, and unipedal standing time <15 s was significant in those >or=65 years. CONCLUSION: Unipedal standing time was shorter and BMD was lower in women >or=50 years of age with distal radius fractures than those in age-matched women without fractures.
