Objective To research the TCM pattern distribution of high-normal blood pressure population in communities.Methods All employees and retirees from education authorities and 108primary and secondary schools in Pingyuan County

Dezhou City

Shandong Province were investigated.The standard pattern questionnaire was used to collect the gender

age

body mass index（BMI）

waist hip ratio（WHR）

blood pressure

heart rate and combined risk factors.The TCM pattern distribution of the subjects was analyzed.Results There were 1 050cases（27.4%）of high-normal blood pressure were found in totally 3 860subjects and the detection rate of the male was higher than that of the female（P<0.05）.The risk factors of high-normal blood pressure were gender

education level

alcohol consumption

history of dyslipidemia and BMI.The proportion of single pattern in high-normal blood pressure population was high and difference occurred with age growth（P<0.01）.Liver fire exuberance pattern was common in people under 50years old.Yin deficiency yang hyperactivity pattern and yin-yang deficiency pattern was common in people over 60years old.The influencing factors of yin deficiency yang hyperactivity pattern and liver fire exuberance pattern were gender.There were significant differences between the kidney deficiency pattern and non kidney deficiency pattern in people with high-normal blood pressure of all ages（P<0.01）.Non kidney deficiency pattern was common in people under 50years old.Kidney deficiency pattern was common in people over 60years old.The influencing factor of kidney deficiency pattern was age.Conclusion The basic patterns of high-normal blood pressure population in communities are liver fire exuberance pattern and yin deficiency yang hyperactivity pattern.The TCM patterns may change from repletion pattern（liver fire exuberance）to deficiency-repletion complex pattern（yin deficiency yang hyperactivity）and finally develop into deficiency pattern（kidney deficiency pattern or yin-yang deficiency）with age

especially in the male.
