Objectives
The aim of this study was to investigate the change in Sasang constitution prediction value in 2 years and find the factors
associated with it.
Methods
Cohort data from Korean medicine data center was used. Using Korean Sasang Constitutional Diagnostic Questionnaire
(KS-15) which consist of questions related to body shape, temperament, and symptoms, participants were categorized
into Tae-Yang (TY), Tae-Eum (TE), So-Yang (SY), and So-Eum (SE). Sasang constitution was assessed on the baseline and
after two years.
Result
Total 5,784 participants were analyzed. (TE 3, 341; SE 911; SY 1,532). Among them, 1,402 participants (24.2%) showed
different prediction value in KS-15 after two years. The proportion of participants showing different prediction value in two
years was the highest in SY, and the lowest in TE group. The factors associated with the change in Sasang constitution prediction
value were different by constitution type. The change in feeling after sweating was significantly associated with the change
in prediction value in TE and SY groups, not in SE group. Although temperament was not significantly associated with the
change in prediction value from TE to SE, it was significantly associated with that in the change from TE to SY. The change
in BMI and appetite were associated with the change in constitution prediction value in all three constitution types.
Conclusion
Although the factors associated with the change in prediction value of Sasang constitution were different by each
constitution type, BMI and appetite were significant in all three types. These factors could be useful for developing Sasang
constitution questionnaire and deciding re-prediction needs of Sasang constitution. Further research about the factors
related to Sasang constitution diagnosis need to be conducted. |
