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.本研究提出一项假说：心肺适能（cardiorespiratory fitness, CRF）与中医（Traditional Chinese Medicine, TCM）气血状态存在关联。本研究为针对中国老年人群的观察性研究，旨在探讨6分钟步行距离（6-minute walk distance, 6MWD）与中医气血状态之间的关联。本次共享数据集包含277名中国老年人的6MWD、中医气血量表评分及其他健康相关信息。研究观察到，约27%的中国老年人（合并基础疾病者亦在此列）出现6MWD降低的情况，提示其心肺适能水平下降。此外，6MWD与中医气血问卷评分呈显著负线性相关，表明心肺适能与中医气血状态之间存在关联。受试者工作特征（Receiver Operating Characteristic, ROC）曲线分析结果显示，中医气血问卷评分在预测6MWD异常方面具备潜在临床应用价值。
