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.
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.
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.
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.
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.
与年龄匹配的无桡骨远端骨折的社区居住的日本女性相比,50 岁及以上因跌倒导致低能量桡骨远端骨折的日本女性的单足站立时间更短,骨密度更低。
本研究的目的是比较年龄匹配的桡骨远端骨折女性与无桡骨远端骨折女性的单足站立时间和骨密度(BMD)。
骨折组为 54 例因跌倒导致低能量桡骨远端骨折的日本女性。非骨折组为 52 例无骨折的社区居住的日本女性。测量单足站立时间和 BMD。
两组在年龄和体重指数方面无显著差异。骨折组单足站立时间<15 s 的女性比例为 44.4%,无骨折组为 13.5%,而>120 s 的女性比例分别为 20.4%和 50.0%。BMD 的 T 评分在骨折组明显低于非骨折组。逻辑回归分析确定单足站立时间<15 s 和 T 评分<70%是与桡骨远端骨折相关的显著因素。值得注意的是,T 评分<70%在<65 岁的患者中是显著的,而单足站立时间<15 s 在>or=65 岁的患者中是显著的。
