Objective To analyze the influencing factors of brachial-and-ankle pulse wave velocity（baPWV）and brachial-ankle indices（BAI）in order to study their correlations with TCM pulse conditions.Methods Totally 244 subjects from physical examination were collected and 12 of them with arterial occlusion of lower limbs were excluded.The subjects were divided into a normal group（87 cases）

a mild sclerosis group（63 cases）

and a sclerosis group（82 cases）according to baPWV.The baPWV and BAI of lower limbs of both sides were determined with an automatic arteriosclerosis surveyor

simultaneously

the general data including age

medical history

blood pressure

blood fat

body weight index

and the pulse conditions were recorded.The linear correlation analysis and the Logistic regression analysis were carried out to determine the influencing factors on arterial elasticity and their correlation with the TCM pulse conditions.Results The systolic pressure

diastolic pressure

average pressure

and arterial differential pressure of the three groups showed a tendency to be increasing along with the increase of baPWV

and the difference among the groups was statistically significant（P<0.01）.There was no difference in blood fat and constitutional index among groups（P>0.05）.There was difference in diabetes history

hypertension history

smoking history

and alcohol drinking history among groups（P<0.01）.Logistic regression analysis showed that the influencing factors of baPWV were age

systolic pressure

and diabetes history

and those of BAI were age and diabetes history（P<0.05）.The pulse conditions that reflecting the degree of arteriosclerosis from weak to strong（weak pulse group

normal pulse group

string-taut pulse group）of baPWV of both sides were gradually advanced with a significant difference among groups（P<0.01）.The pulse conditions that relating to the thickness of artery（thready pulse group

normal pulse group）of BAI of both sides were gradually advanced with a significant difference among groups（P<0.01）.Conclusion Age

systolic pressure

and the diabetes history are the influencing factors in the early atherosclerosis

and baPWV and BAI are closely related to the TCM pulse conditions.
