The gender ratio of male and female was 82: 100. The average age of the patients was (50.6 +/- 17.7) years old. The number of patients over 45 years old was more obvious than groups of other ages (P<0.05). Age differences can be found in those 6 regions (P<0.05). Clinical symptoms varied according to different ages of the patients. Different characteristics of age distribution of acupuncture indications were held to exist (P=0.000).
