The Factors Associated with Chill Syndrome Using Terasawa's ki, ketsu and sui (qi, blood and fluid) Diagnostic Score / 日本東洋医学雑誌

To determine the physical symptoms and ki, ketsu and sui (qi, blood and fluid) factors associated with the presence of hie-sho (chill syndrome). Total 118 healthy university students (66 males and 52 females, median age 22 years, range 21­-29) were enrolled. A cross-­sectional study about the presence of chill syndrome in par­ticipants was performed. Terasawa's ki, ketsu and sui diagnostic score was used to identify the presence of physical symptoms. Number rating scale (NRS) was used to classify the chill and NRS more than 5 was de­fined as chill syndrome based on Furuya's report. Eighteen students (4 males and 14 females) were docu­mented as chill syndrome. The multivariate analysis of physical symptoms identified female (OR 4.65, p = 0.0427), heavy sensation of head (OR 2.98, p = 0.0190) and chill of extremities (OR 1.94, p = 0.0480) as sig­nificantly associated factors with chill syndrome. The score of ki-kyo (qi deficiency), ketsu-kyo (blood defi­ciency) and suitai (fluid retention) showed higher score in students with chill syndrome compared to students without chill syndrome in univariate analysis. Being female and two indicators of qi abnormalities including heavy sensation of head and chill of extremities were associated with the presence of chill syndrome in univer­sity students.
