An observational study on 6-minute walk distance and its relationship with TCM Qi and blood status among Chinese older adults.

This study proposes a hypothesis that an association between cardiorespiratory fitness (CRF) and Traditional Chinese Medicine (TCM) Qi and blood status. This is an observational study on 6-minute walk distance (6MWD) and its relationship with TCM Qi and blood status among Chinese older adults.The sharing data included 6MWD, TCM Qi and blood scale scores, and other health information from 277 Chinese older adults. We observed that about 27% of Chinese older adults, including those with underlying diseases, exhibited reduced 6MWD, suggesting decreased CRF. Furthermore, 6MWD was significantly negatively linearly correlated with the TCM Qi and blood questionnaire scores, indicating an association between CRF and Qi and blood status. ROC analysis indicated that the TCM Qi and blood questionnaire score has potential clinical value in predicting abnormal 6MWD.

本研究提出一项假设，即心肺功能（CRF）与中医气血状态的关联。该研究为一项关于中国老年人群6分钟步行距离（6MWD）及其与中医气血状态关系的观察性研究。共享数据包括6MWD、中医气血量表评分及其他来自277名中国老年人的健康信息。观察发现，约27%的中国老年人，包括患有潜在疾病者，表现出6MWD降低，提示心肺功能下降。此外，6MWD与中医气血问卷评分呈显著负线性相关，表明心肺功能与气血状态之间存在关联。ROC分析表明，中医气血问卷评分在预测异常6MWD方面具有潜在的临床价值。
