This study analyzed whether sarcopenia, a risk factor for disability in the aged, also occurs in healthy community-dwelling elders with normal nutritional state. As indicators, body cell mass (BCM) and lean body mass (LBM) were determined in 110 Germans (ages 60-83) using bioimpedance analysis. Nutritional status, muscle function, anthropometry, and physical activity level were investigated. Sarcopenia was already present in well nourished healthy elders. Its prevalence depended on the measure of muscle mass used (BCM percent, 22 percent males, 20 percent females; LBM percent, 4 percent males, 11 percent females). In conclusion, screening for presence of sarcopenia is needed in healthy, well-nourished elderly populations requiring an international standardization.
本研究分析了肌肉减少症（老年人残疾的一个风险因素）是否也会出现在营养状况正常、居住在社区的健康老年人中。作为指标，使用生物电阻抗分析测定了110名德国人（年龄60 - 83岁）的身体细胞质量（BCM）和去脂体重（LBM）。对营养状况、肌肉功能、人体测量学和身体活动水平进行了调查。肌肉减少症在营养良好的健康老年人中已经存在。其患病率取决于所使用的肌肉量测量方法（BCM百分比，男性为22%，女性为20%；LBM百分比，男性为4%，女性为11%）。总之，在需要国际标准化的健康、营养良好的老年人群中，有必要筛查肌肉减少症的存在情况。
