Correlation between Tibetan and traditional Chinese medicine body constitutions: A cross-sectional study of Tibetan college students in the Tibet Autonomous Region

Abstract

Abstract Objective To evaluate the correlation between the body constitution types of Tibetan medicine and traditional Chinese medicine (TCM). Methods The cluster sampling method was employed to recruit participants from a university in the Tibet Autonomous Region. Tibetan medicine and TCM questionnaires were respectively used to assess the participants' constitution information. Descriptive statistics were applied to analyze the baseline and constitution characteristics of the participants. Two-factor correlation analysis and the paired chi-square test were applied to analyze the correlation between Tibetan and TCM constitution types. Results Data from 466 Tibetan students were analyzed. The mean scores of the rlung, mkhris pa, and bad kan constitution types in Tibetan medicine were 43.2 (11.1), 42.1 (10.1), and 45.0 (8.0), respectively; participants with the three-factor convergence body constitution type accounted for 13.7% of the whole population. Among the TCM constitution types, qi stagnation was the most common (21.5%), followed by the balance type (16.5%); the other constitutions detected were qi deficiency, yin deficiency, and yang deficiency. The rate of consistency for the identification of the three-factor convergence constitution in Tibetan medicine and the balance constitution in TCM was 89.1%, with a Kappa coefficient of 0.57 (P > .05). The rlung constitution in Tibetan medicine was associated with the yin deficiency, yang deficiency, and blood stasis constitutions in TCM. The mkhris pa constitution in Tibetan medicine was associated with the damp heat and yin deficiency constitutions in TCM. The bad kan constitution in Tibetan medicine was associated with the phlegm dampness, qi deficiency, and yin deficiency constitutions in TCM. Conclusion There is a correlation between the body constitution types of Tibetan medicine and TCM. The reliability and validity of the Questionnaire for Tibetan Medicine Constitution requires improvement, and more studies with larger sample sizes and more varied populations are warranted to verify the correlation between Tibetan medicine and TCM constitutions.
