OBJECTIVE
Analyzed the association of bone mass with the functional capacity of elderly aged 80 or more.
METHODS
The sample consisted of 93 elderly aged 80 and 91 years (83.2±2.5 years) being 61 women (83.3±2.7 years) and 32 men (83.1±2.2 years) living in the city of Presidente Prudente - São Paulo/Brazil. The assessment of bone mass was realized by absorptiometry dual-energy X-ray (DXA), where have been measured values bone mineral content (BMC) and bone mineral density (BMD) of the femur and spine (L1-L4). The functional capacity was evaluated by means of walking speed tests, static equilibrium and strength of lower limbs contained in the questionnaire Wellness Health and Aging (SABE). The variables of bone mass and functional capacity were categorized according to the median values and score tests, respectively. For statistical analysis we carried out the chi-square test, the software used was SPSS (13.0) and the significance level was set at 5%.
RESULTS
Elderly male with higher performance in the functional tests showed higher femur BMC compared to lower performance, result not found when evaluated women.
CONCLUSION
Thus, the bone of the femur for the oldest old male is associated with functional capacity. The constant assessment of the bone mineral mass and practive of physical activity throughout life would be measures to prevent falls in the elderly.
目的
分析80岁及以上老年人骨量与功能能力之间的关联。
方法
样本包括93名年龄在80至91岁之间（83.2±2.5岁）的老年人，其中61名女性（83.3±2.7岁）和32名男性（83.1±2.2岁），他们生活在巴西圣保罗州普鲁登特总统城。通过双能X线吸收法（DXA）进行骨量评估，测量了股骨和脊柱（L1-L4）的骨矿物质含量（BMC）和骨矿物质密度（BMD）值。通过步行速度测试、静态平衡和《健康、衰老与身体活动问卷》（SABE）中包含的下肢力量来评估功能能力。骨量和功能能力变量分别根据中位数和得分测试进行分类。进行统计分析时采用卡方检验，使用的软件为SPSS（13.0），显著性水平设定为5%。
结果
在功能测试中表现较好的老年男性与表现较差的相比，股骨BMC更高；评估女性时未发现此结果。
结论
因此，高龄男性的股骨骨量与功能能力相关。持续评估骨矿物质质量以及终身进行体育锻炼将是预防老年人跌倒的措施。
