摘　　要：目的应用相似度分析方法,对亚健康状态的人群的临床症状进行特征分析,探讨各个症状间的相似程度。方法使用4种不同计算方法分析亚健康的流行病学调查数据;同时通过相似度分析提炼亚健康状态的重要临床特征。结果采用4种方法对亚健康症状的分析结果符合临床实际,精简了亚健康的症状数量。结论使用夹角余弦、相似度D、谱图相似度3种相似度分析方法比传统的相关分析准确度高,与临床实际基本相符。该方法可简化临床症状指标数量,可形成亚健康状态的某些特征要素,为亚健康状态的评价研究提供方法学参考。Objective To analyze the symptoms of people with sub-health in order to explore the similarity among symptoms with the method for similarity analysis.Methods 4 methods were used to analyze the epidemiological data in sub-healthy people and summarize the clinical characteristics.Results The analisis results with 4 methods were accordant with clinical symptoms,simplified the quantity of sub-health symptoms.Conclusion As compared with the traditional correlation coefficient analysis,method of cosine distance,correlation coefficient,D and special similarity,showed a higher level of accuracy.The results obtained were basically matched with clinical practice.So,the technique could be taken as a method for simplifying clinical parameters and finding the typical characteristic elements.
