Analysis of the intervention effect of Traditional Chinese Medicine diet on constitution and meridian energy
传统中医药膳对体质及经络能量的干预效果分析

摘要

目的 探讨特定干预措施对人群中医体质（阴、阳指数）及经络能量的调节作用，验证其在体质调理与经络疏通方面的疗效。中医药膳作为“治未病”核心手段，既往研究多聚焦单一体质，缺乏对阴阳指数与经络能量协同变化的系统评价。方法 将受试者分为对照组（20例）与干预组（164例）。对两组干预前（基线）及干预后（干预后）的阴指数、阳指数及经络能量进行测定。采用重复测量方差分析比较各项指标随时间的变化趋势及组别差异；采用卡方检验比较两组在阴阳和指数、经络能量及整体效果上的改善率。结果 重复测量方差分析显示，干预组在干预前后的阴指数（58.1±22.7增加至68.6±18.3）和阳指数（61.3±20.8增加至72.3±14.9）分别平均提升10.5和11.0分，阴阳皆得到滋补；经络能量（39.0±26.6降至27.4±20.6）下降11.6分，脏腑经络趋于平衡平和。三项指标的组别主效应均无显著性差异，但组别×时间交互效应均具有统计学意义（P<0.05或P<0.01），表明干预组随时间的变化趋势与对照组存在显著差异。卡方检验显示，干预组的阴阳和指数改善率（66.5% vs 20.0%）、经络能量改善率（73.8% vs 30.0%）及整体效果改善率（68.3% vs 25.0%）均显著高于对照组，差异均有统计学意义（P<0.05或P<0.01）。结论 中医药膳具有确切的中医体质调理与经络疏通作用。其机制可能在于通过调节机体阴阳平衡的整体机制，促使机体从偏弱或偏盛状态趋于平衡，但尚需进一步机制实验验证；且阴、阳指数与经络能量的改善具有协同效应，充分体现了中医体质餐“阴阳同补”、“五脏同调”的特色与优势。

Abstract

Objective To explore the regulatory effects of a specific intervention on Traditional Chinese Medicine (TCM) constitution (Yin and Yang indices) and meridian energy in a population, and to verify its efficacy in constitution regulation and meridian dredging. As a core means of treating potential disease, TCM dietary therapy has been the focus of previous research largely on single body constitutions, lacking a systematic evaluation of the synergistic changes between the Yin-Yang index and meridian energy.
Methods The subjects were divided into a control group (n=20) and an intervention group (n=164). The Yin index, Yang index, and meridian energy of both groups were measured before (baseline) and after the intervention. Repeated measures analysis of variance (ANOVA) was used to compare the trends of changes over time and the differences between groups. The Chi-square test was used to compare the improvement rates of the Yin-Yang sum index, meridian energy, and overall efficacy between the two groups.
Results Repeated-measures ANOVA showed that in the intervention group, the Yin index increased from 58.1±22.7 to 68.6±18.3, the Yang index increased from 61.3±20.8 to 72.3±14.9, representing average increases of 10.5 and 11.0 points, respectively. The meridian energy decreased from 39.0±26.6 to 27.4±20.6, a reduction of 11.6 points. No significant main effect of group was observed for any of the three indicators; however, the group × time interaction effects were all statistically significant (P<0.05 or P<0.01), indicating that the temporal trends of the intervention group differed significantly from those of the control group. The Chi-square test revealed that the improvement rates of the Yin-Yang sum index (66.5% vs. 20.0%), meridian energy (73.8% vs. 30.0%), and overall efficacy (68.3% vs. 25.0%) in the intervention group were significantly higher than those in the control group, with all differences being statistically significant (P<0.05 or P<0.01).
Conclusion   The TCM diet has a definitive effect on regulating TCM constitution and dredging meridians. Its mechanism may lie in regulating the holistic mechanism of the body’s Yin-Yang balance, thereby prompting the body to shift from a deficient or excessive state to a balanced one, but further mechanism experiments are still needed for verification. Furthermore, the improvements in the Yin and Yang indices and meridian energy demonstrate a synergistic effect, fully reflecting the characteristics and advantages of the TCM constitution diet in “holistic constitution regulation”.
