Correspondence analysis of chinese medical constitution features in different ages population / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the distribution features of Chinese medical constitutions in different ages population, thus providing scientific evidence of constitution process theory.</p><p><b>METHODS</b>Recruited were 21 948 cases from a survey of Chinese medical constitutions and health conditions in 9 provinces or municipalities across China (including Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan) from Dec 2005 to Jan 2007. The body constitution type of individual was diagnosed using discriminant analysis on the basis of Chinese medical constitution questionnaire. By using correspondence analysis, the correlation between the general population, genders, ages, and Chinese medical constitution types was studied.</p><p><b>RESULTS</b>Constitutions of yin-deficiency type, wetness-heat type, qi-depression type, and special diathesis type often occurred in the population ranging 15 -24 years old. Gentleness type mostly occurred in the population ranging 25 -44 years old. During this time period, phlegm-wetness type and wetness-heat type were liable to occur in males, while blood-stasis type was liable to occur in females. Qi-deficiency type and yang-deficiency type were most often seen in those older than 45 years. Phlegm-wetness type and blood-stasis type body constitution were also liable to occur in those older than 45 years.</p><p><b>CONCLUSIONS</b>The distribution features were different in different Chinese medical constitutions. Different constitution types exist in different genders. Different constitution types exist different ages population.</p>
