飲用洛神茶對長期尿管留置老人尿液pH值及血壓等影響的調查

Investigation of the Effect of Drinking Roselle Tea on the Urine pH and Blood Pressure of Long Term Foley-Installed Elderly

本研究以洛神茶為飲料，調查其對長期尿管留置老人尿道感染及健康的影響。調查對象為長期尿管留置的老人含醫院、安養中心、對照等三組共30人，每人每日飲用300ml洛神茶，為期八個月，並分別由其尿液、血液、血壓三方面的變化加以探討。結果顯示，在尿液方面，醫院及安養中心的老人到第四個月時，尿液的pH值及細菌數明顯下降，如醫院組尿液平均由pH 7.9下降為pH 5.6，細菌數由log值5.3下降至log值1，而對照組則否，推測當尿液偏弱酸性時有助於抑制細菌的滋長。血液生理值方面，醫院組的三酸甘油酯在供應前後由147 mg／dl降為98 mg／dl。此外，膽固醇平均由245 mg／dl降為148 mg／dl，安養中心組及對照組則僅些微下降。就血糖及血壓而言，醫院及安養中心組下降明顯，對照組則無明顯的變化。故飲用洛神茶八個月，可明顯降低長期尿留置老人之泌尿道感染，以及血液中三酸甘油酯與膽固醇的含量，並有助於收縮壓的下降。 This study was aimed at investigating the effect of drinking Roselle tea on the urinary infection and general health of long term foley-installed elderly . Study objects included 30 elderly citizens which were categorized into 3 groups: hospital, retirement home, and control, respectively. Daily intake of roselle tea was 300 ml, and the period lasted for 8 months. Biological testing data were regularly acquired, and were divided into urine, blood, and blood pressure, respectively. Results showed that, for the groups of hospital and retirement home, the pH values and bacterial numbers in urine significantly reduced, compared to relatively unchanged figures for control group. For example, pH value decreased from 7.9 to 5.6, while the bacterial number declined from 105.3 to 101 for hospital group after 4 months. It suggested that roselle tea facilitated the acidification of urine, which in term inhibited the growth of bacterial and the urinary infection. Blood physiological data also revealed the significant decreases in triglyceride, cholesterol level, and blood sugar. Triglyceride and cholesterol of hospital groups fell from 147mg/dl to 98 mg/dl, and 245mg/dl to 148 mg/dl respectively, but changed only a little for control group. Reduction in blood sugar and blood pressure were significant for groups of hospital and retirement home, while practically unchanged for control group. It was concluded that daily intake of roselle tea for the period of 8 months helped to reduce the urinary infection, triglyceride, cholesterol level, blood sugar, and blood pressure, for the long term foley-installed elderly.
