方法：研究对象年龄在69岁以上，能够独立行走，并参加了五个老年门诊。采用生物阻抗分析（BIA）评估身体成分，采用JAMAR测力计评估握力，并通过4 m步态速度评估身体表现。采用EGWSOP标准（步态速度< 0.8 m/s;男性握力< 30 kg或女性握力< 20 kg;男性肌肉质量指数（MMI）< 8.31 kg/m2或女性< 6.68 kg/m2）诊断肌少症。19.1%的患者存在肌肉减少症（男性12.7%，女性22.9%）; 20.1%的患者存在肌肉量不足; 68.8%的患者存在步态速度不足和81.2%的患者存在握力不足。低握力组和低步速组中分别有21.9%和19.5%的人出现肌肉减少症。肌肉质量和肌肉力量或步态speeds.Conclusions之间没有相关性：肌肉减少症是存在于五分之一的老年门诊。
Methods: subjects over 69 years old, able to walk without help and who attended five geriatric outpatient clinics were recruited. Body composition was assessed using bioimpedance analysis (BIA), grip strength using a JAMAR dynamometer and physical performance by the 4 m gait speed. Sarcopenia was diagnosed using the EGWSOP criteria (gait speed < 0.8 m/s; grip strength < 30 kg in men or < 20 kg in women, and muscle mass index (MMI) < 8.31 kg/m(2) in men or < 6.68 kg/m(2) in women).Results: two hundred and ninety-eight subjects were included (median age 83.2 years, 63.1% women). 19.1% had sarcopenia (12.7% men, 22.9% women); 20.1% had low muscle mass; 68.8% had low gait speed and 81.2% low grip strength. Only 21.9% of the subjects with low grip strength and 19.5% of those with low gait speed had sarcopenia. No correlations between muscle mass and either muscle strength or gait speed were detected.Conclusions: sarcopenia is present in one out of five subjects attending geriatric outpatient clinics.
