本研究的目的是评估在巴塞罗那（西班牙）的一个城市地区的健康社区居住的老年人的骨骼肌减少症的患病率，并将其与其他地理区域发表的文献进行比较，我们前瞻性地评估了一系列的200名健康老年人在社区保留的功能能力和认知功能障碍的情况下。我们进行了全面的老年评估，并确定人体测量数据，肌肉质量（MM）和肌肉质量指数（MMI）。通过生物电阻抗分析（BIA）评估肌肉质量。定义少肌症MMI的截止点确定为小于参考组（包括同一地区的220名健康志愿者（20-42岁））平均值的2 SD。结果与美国、法国和台湾的研究进行了比较，得出的截断点为男性8.31 Kg/m2，女性6.68 Kg/m2，与法国和台湾的观察结果相似，但与美国不同。观察到的肌肉减少症的患病率在老年女性中为33%，在男性中为10%。在比较四个人群中肌肉减少症的患病率时，我们观察到了一些差异，特别是在男性中。我们还观察到，在健康的老年社区，特别是女性，肌肉减少症的患病率显着，显示出一些与其他地理区域的差异。
The purpose of this study was to evaluate the prevalence of sarcopenia in a cohort of healthy community-dwelling elderly in an urban area in Barcelona (Spain) for native benchmarks and compare them with those published in other geographical areas.We prospectively evaluated a series of 200 healthy elderly in the community with preserved functional capacity and absence of cognitive impairment. We performed a comprehensive geriatric assessment and determined anthropometric data, muscle mass (MM) and the muscle mass index (MMI). Assessment of muscle mass was performed by bioelectrical impedance analysis (BIA). The cut-off point for defining sarcopenia MMI was established as less than 2 SD of the mean of a reference group comprising 220 healthy volunteers (20-42 years) in the same area. Results were compared with studies undertaken in the USA, France and Taiwan.The cut-off points obtained were 8.31 Kg/m(2) for men and 6.68 Kg/m(2) for women, being similar to those observed in France and Taiwan but different from the USA. The prevalence of sarcopenia observed was 33% for elderly women and 10% for males. On comparison of the prevalence of sarcopenia in the four populations, we observed some differences, particularly in males.We have defined reference values for sarcopenia, determined by BIA, in our setting. We also observed a remarkable prevalence of sarcopenia in the healthy elderly community, especially in females, showing some differences from those in other geographical regions.
