The objectives of this study are to evaluate the effectiveness of Chinese food therapy in correcting the Yin-deficiency and to examine its impact on the patients' quality of life and hypertension control.
Epidemiological studies have shown 14-50% of people with hypertension have Yin-deficiency. Whether restoring the Yin-Yang balance by means of Chinese food therapy can help to better manage patients with hypertension has yet to be examined.
Two groups randomised controlled trial.
Eighty-five hypertensive patients recruited from two community health service centre were divided into two groups. The intervention group (n = 48) received specific dietary instructions and corresponding management of their antihypertensive medication if indicated and brief health education, whilst the control group (n = 37) received routine support involving only brief health education. Data were collected at baseline, after intervention at four, eight, 12 and 16 weeks follow-up. Comparisons were made to examine the effects of Chinese food therapy on Yin-deficiency symptoms, blood pressure and quality of life of hypertensive patients.
The intervention group had reduction in the numbers of antihypertensive medication taken as well as improvement in most of the Yin-deficiency symptoms after 12 weeks of Chinese food therapy and mean scores of several SF-36 dimensions were higher than that of in the control group after 12 and 16 weeks follow-up. Significant difference was found in systolic blood pressure in the intervention group when it was compared from baseline to after four and eight weeks respectively.
Chinese Food Therapy can restore body constitution with Yin-Yang imbalance and may potentially improve hypertensive patients' quality of life. It is also beneficial in controlling blood pressure in hypertensive patients.
Chinese food therapy may become a complementary therapy in health care and it should be a component of nursing education and health education.
本研究旨在评估中医食疗纠正阴虚的效果，并探讨其对患者生活质量和高血压控制的影响。
流行病学研究表明，14-50%的高血压患者存在阴虚。通过中医食疗恢复阴阳平衡是否有助于更好地管理高血压患者，尚未得到验证。
两组随机对照试验。
从两个社区卫生服务中心招募了 85 名高血压患者，将他们分为两组。干预组（n=48）接受特定的饮食指导和相应的降压药物管理（如有需要）以及简短的健康教育，而对照组（n=37）仅接受常规支持，包括简短的健康教育。在基线、干预后 4、8、12 和 16 周随访时收集数据。比较两组中医食疗对高血压患者阴虚症状、血压和生活质量的影响。
经过 12 周的中医食疗，干预组服用的降压药物数量减少，大多数阴虚症状得到改善，并且在 12 和 16 周随访时，SF-36 几个维度的平均得分均高于对照组。与基线相比，干预组的收缩压在干预后 4 周和 8 周分别有显著降低。
中医食疗可以纠正阴阳失衡的体质，可能潜在改善高血压患者的生活质量，并且有益于控制高血压患者的血压。
中医食疗可能成为医疗保健的一种补充疗法，应成为护理教育和健康教育的组成部分。
