Objective To explore Chinese medicine constitution status and related factors of elderly hypertension community-based patients.Methods Adopt multistage stratified sampling method.Select 3 communities in Shanghai.Then randomly extract 2 residents groups in each community respectively to collect general demographic data and related data of Chinese medicine constitution characteristics and behavior life style of research objects.Analyze the relationship between Chinese medicine constitution characteristics and related factors.Results Abnormal constitution of 808 investigated elderly hypertension community-based patients was mainly Qi deficiency constitution（28.59%）

Yang deficiency constitution（22.03%）

Yin deficiency constitution（17.70%）and phlegm-dampness constitution（16.21%）.The difference of different gender patients of normal constitution

Qi deficiency constitution

blood stasis constitution

Qi stagnation constitution and specific diathesis constitution was significant（P < 0.05）.The proportion of normal constitution was larger in male

while the proportion of Qi deficiency constitution

blood stasis constitution

Qi stagnation constitution and specific diathesis constitution was larger in female.The proportion of normal constitution was larger in non-smokers

while the proportion of Qi deficiency constitution

Yin deficiency constitution and Qi stagnation constitution was larger in smokers（P < 0.05）.There was a positive correlation between weight and phlegm-dampness constitution in male subjects.There was a negative correlation between female weight and Yang deficiency constitution in female subjects（P < 0.05）.There was a positive correlation between waist circumference and Qi deficiency constitution

phlegm-dampness constitution

dampness-heat constitution and Qi stagnation constitution in male（P < 0.05）.While there was a negative correlation between body mass index（BMI）and Yang deficiency constitution

a positive correlation between BMI and phlegm-dampness constitution and dampnessheat constitution（P < 0.05）.Drug compliance of hypertension patients was related to constitution（P < 0.001）.With the better drug compliance

there is higher scores of normal constitution

and lower scores of other abnormal constitution.Conclusion Abnormal constitution of elderly hypertension community-based patients was mainly Qi deficiency constitution

Yang deficiency constitution

Yin deficiency constitution and phlegm-dampness constitution.Gender

smoking and drug compliance were main factors to influence constitution status.
