OBJECTIVE: To investigate the distribution of constitution types of Chinese medicine (CM) in the elderly living at home in Beijing downtown, and to explore its relationship with life habits. METHODS: A total of 3894 senile more than 60 years old were enrolled in this study. Their constitution types of CM were typed using CM constitution questionnaire. Meanwhile, their demographic features, disease condition, diet habits, exercise habits, sleep habits, and so on were investigated. Multivariate Logistic regression analysis was used to evaluate the relationship between life habits and constitution types of CM. RESULTS: The number of mild type constitution senile was 1111 (28.53%) and the number of biased constitutions 2783 (71.47%). Biased constitutions of the top three were qi deficiency constitution (662, 17.00%), yang deficiency constitution (445, 11.43%), and blood stasis constitution (363, 9.32%). Univariate analysis showed that different habits of diet, exercise, and sleep exist among the senile of different constitutions (P < 0.05). By taking mild type constitution, multivariate Logistic regression analysis (except demographic indices and chronic history) showed that significantly positive correlation existed between qi deficiency constitution and favor for hot food (OR = 1.349, P = 0.015), yang deficiency constitution and favor for hot food (OR = 2.448, P < 0.01), phlegm-wetness constitution and favor for barbecue food (OR = 2.144, P = 0.003), wet-heat constitution and favor for sweet food (OR = 1.355, P = 0.032), wet-heat constitution and favor for tea (OR = 1.359, P = 0.047), blood stasis constitution and favor for hot food (OR = 1.422, P = 0.017), and qi depression constitution and favor for hot food (OR = 1.446, P = 0.031). Regular exercise had negative correlation with qi deficiency constitution (OR = 0.397, P < 0.01), yang deficiency constitution (OR = 0.522, P < 0.01) , phlegm-wetness constitution (OR = 0.475, P < 0.01), wet-heat constitution (OR = 0.647, P = 0.015), blood stasis constitution (OR = 0.608, P = 0.001), qi depression constitution (OR = 0.541, P = 0.001), and special diathesis constitution (OR = 0.466, P < 0.01). Early sleep and rise habit had negative with phlegm-wetness constitution (OR = 0.414, P < 0.01), wet-heat constitution (OR = 0.536, P = 0.015), blood stasis constitution (OR = 0.515, P = 0.004), and special diathesis constitution (OR = 0.526, P = 0.039). CONCLUSIONS: Different constitution types of CM might be highly related to specific life habits. Cultivating better life habits can improve biased constitutions of CM.
