| Changes of Constitution in Chinese Medicine Questionnaire | The Constitution in Chinese Medicine Questionnaire (CCMQ) consists of 60 items to classify a person into one or more of nine Body constitution(BC) types: gentleness (8 Items), Qi-deficiency (8 Items), Yang-deficiency (7 Items), Yin-deficiency (8 Items), phlegm-wetness (8 Items), wetness-heat (6 Items), blood-stasis (7 Items), Qi-depression (7 Items), and special diathesis (7 Items). Coexistence of multiple imbalanced BC types was possible which is consistent with the TCM theories. The scoring algorithm proposed in the original CCMQ was adopted in this study. A higher score in the CCMQ BC scale indicates a higher likelihood of the specific BC type, and a score of 30 is set as threshold for case definition. The CCMQ will be conducted at baseline, 12 weeks, and follow-up (16 weeks). | week 0, 12, 16 |
