Epidemiological study of clinical symptoms of sub-health / 中华健康管理学杂志

ABSTRACT

Objective To epidemiologically analyze the common clinical symptoms of sub-health in Beijing area.Methods By analysis of sub-health,epidemiologlcal data and the method of factors analysis, we studied the features and properties of various symptoms and their relationships that represent various kinds of sub-health.We used the structural equation modeling to validate the relationship between the symptom groups and between the symptom groups and their components.Results The amount of the factors whose weight Values were larger than 1.0 was 13,and the cumulative value of all the factors was 55.67%.With the domain knowledge,however,the total factors were merged into 10.We took fatigue as the main hidden variable to build a structural equation model.The function was x2/df=3.65,and GFI,AGFI,CFI,Tucher Lewis indexes were all above 0.9.The direct effects between the hidden variables showed that fatigue is closely related to fatigue of eyes,sleep,and pain with the weighted coefficient ranging from 0.7 to 1.0. Fatigue is somehow related to the symptoms of stool,pee,fauces,mouth,and sweat with the weighted coefficients about 0.5.The indirect effects between fatigue and hidden vailables showed that fatigue has an effect on moods indirectly with standardized indirect effects and standardized total effects was 0.702 and 0.112.respectively.Conclusions The symptoms of sub-health are complex with a dominating symptom and many other secondary symptoms.The common symptom groups are maladjustment of mood,fatigue, abnormity of sleep,maladjustment of stool and pee,double-minded,fatigue of eyes,and pain.The results of structural equation model shows that the causality between symptoms that are in a symptom group is different,so is the causality between the symptom groups,which shows that the symptoms of the sub-health are of diversity.
