Abstract

OBJECTIVE

To determine the prevalence of sarcopenia in community-dwelling elderly populations in Chengdu and its associated risk factors.

METHODS

A total of 947 community dwelling residents aged ≥60 yr. in Chengdu participated in this study. Their appendicular skeletal muscle mass was measured through bioelectrical impedance analyses. Sarcopenia was defined using the diagnostic algorithm recommended by the Asia Working Group (AWGS) for Sarcopenia. Data in relation to the demographic characteristics, chronic diseases and life style of the participants were obtained through a questionnaire survey, which included the 15-item geriatric depression scale (GDS-15) and the mini nutritional assessment (MNA).

RESULTS

Overall, 10.5% of the elderly participants were identified with sarcopenia: 8.4% in men and 12.5% in women. The prevalence of sarcopenia increased with age: 2.3% in the 60-64 yr., 5.6% in the 65-74 yr., 19.7% in the ≥75 yr.. Age [odds ratio ()=1.109, 95% confldence interval ():1.054-1.168], smoking (=3.482, 95%:1.356-8.938) and Malnorishment (=5.598, 95%:2.677-11.709) are significant predictors of sarcopenia after adjustment for potential confounders.

CONCLUSION

Approximately 10% community-dwelling elderly in Chengdu have sarcopenis. Age, smoking, malnutrition are risk factors of sarcopenia.

摘要

目的

确定成都社区居住老年人群中肌肉减少症的患病率及其相关危险因素。

方法

共有947名年龄≥60岁的成都社区居民参与了本研究。通过生物电阻抗分析测量他们的四肢骨骼肌质量。采用亚洲肌肉减少症工作组（AWGS）推荐的诊断算法定义肌肉减少症。通过问卷调查获取参与者的人口统计学特征、慢性病和生活方式等数据，问卷包括15项老年抑郁量表（GDS - 15）和微型营养评定量表（MNA）。

结果

总体而言，10.5%的老年参与者被诊断为肌肉减少症：男性为8.4%，女性为12.5%。肌肉减少症的患病率随年龄增长而增加：60 - 64岁年龄段为2.3%，65 - 74岁年龄段为5.6%，≥75岁年龄段为19.7%。在对潜在混杂因素进行调整后，年龄[比值比（OR）=1.109，95%置信区间（CI）：1.054 - 1.168]、吸烟（OR = 3.482，95%CI：1.356 - 8.938）和营养不良（OR = 5.598，95%CI：2.677 - 11.709）是肌肉减少症的显著预测因素。
