浙江部分地区肌少症发病率、中医证型分布及影响因素调查分析

目的 调查浙江部分地区肌少症的发生率，分析患者中医证型分布情况及影响因素。方法 选取浙江部分地区1420例60岁以上受试者，调查患者一般资料，测量营养状态等相关指标，采集患者中医四诊资料，应用单因素及多因素Logistic回归分析影响肌少症发生的因素。结果 1420例60岁以上受试者，其中278例受试者确诊为肌少症，占19.58%。278例肌少症患者中脾胃湿热证90例（32.37%），脾胃虚弱证92例（33.09%），肝肾不足证96例（34.53%）。单因素分析显示，浙江部分地区肌少症的发生与年龄、臀围、上臂围、小腿围、腰围、体力活动水平、营养状态及握力有关（P<0.05），但与性别、民族、文化程度、运动方式、家庭月收入、身高、体质量、吸烟史及饮酒史等无关（P>0.05）；将单因素分析具有差异的结果纳入行多因素Logistic回归分析，结果显示，年龄、营养状态、小腿围、体力活动均为影响肌少症发生的独立因素（P<0.05）。结论 浙江部分地区肌少症发病率较高，中医证型分布无明显特征，年龄、营养状态、小腿围、体力活动均为影响肌少症发生的独立因素。

Investigation and analysis of the incidence, TCM syndrome distribution and influencing factors of sarcopenia in some areas of Zhejiang

Objective To investigate the incidence of sarcopenia in some areas of Zhejiang, and to analyze the distribution of TCM syndrome types and influencing factors. Methods The convenience sampling method was performed to select 1420 elderly people over 60 years old in some areas of Zhejiang, the general data of the patients were investigated, the nutritional status and other related indicators were measured, the data of the four diagnosis of traditional Chinese medicine were collected, and the factors affecting the occurrence of sarcopenia were analyzed by univariate and multivariate Logistic regression. Results A total of 1420 subjects over the age of 60 were investigated in this study, of which 278 subjects were diagnosed with sarcopenia, accounting for 19.58%. Among the 278 sarcopenia patients, there were 90 cases of spleen and stomach damp-heat syndrome (accounting for 32.37%), 92 cases of spleen and stomach deficiency syndrome (accounted for 33.09%), and 96 cases of liver and kidney deficiency syndrome (accounted for 34.53%). Univariate analysis showed that the incidence of sarcopenia in some areas of Zhejiang was related to age, hip circumference, upper arm circumference, calf circumference, waist circumference, physical activity level, nutritional status and grip strength (P<0.05), but not related to gender, ethnicity, educational level, exercise mode, family monthly income, height, body weight, smoking history and drinking history (P>0.05); The results of univariate analysis with differences were included in multivariate Logistic regression analysis, and the results showed that age, nutritional status, calf circumference, and physical activity level were all independent factors affecting the occurrence of sarcopenia (P<0.05). Conclusion The incidence of sarcopenia is high in some areas of Zhejiang, and the distribution of TCM syndrome types has no obvious characteristics. Age, nutritional status, calf circumference, and physical activity level are all independent factors affecting the occurrence of sarcopenia.
