笔者把60～85岁舒张压为11.3～13.3kPa(85～100mmHg)的老人56例进行了随机、有对照设计的临床研究。实验目的是观察由降低体重、限制钠盐摄入和增加身体活动组成的一种非药物性治疗方法的效果。本治疗高血压的非药物性治疗方法分为两个单独的阶段,即强化治疗阶段8周,然后维持治疗4个月;对照组在研究中不接受任何治疗。血压由获得证书的技术员(采用盲法进行组间分配)随机用校正过的血压计测得。结果在56名随机参试者中47名完成整个6个月的试验,其中21人在治疗组,26人在对照组。在6个月的实验时间内治疗组比对照组的体重减低得多,分别为-2.1kg,+0.3kg。治疗组及对照
The author of 60 to 85-year-old diastolic blood pressure of 11.3 ~ 13.3kPa (85 ~ 100mmHg) elderly 56 patients were randomized, controlled design of clinical studies. The purpose of the experiment was to observe the effect of a non-drug treatment consisting of weight reduction, sodium intake restriction and increased physical activity. The treatment of hypertension non-drug treatment is divided into two separate phases, the intensive treatment phase of 8 weeks, and then maintained for 4 months; control group in the study did not receive any treatment. Blood pressure was measured with a certified sphygmomanometer (randomized blinded distribution) using a calibrated sphygmomanometer at random. Results Of the 56 randomized participants, 47 completed the entire 6-month trial, 21 of whom were in the treatment group and 26 in the control group. The body weight of the treated group was significantly reduced by -2.1 kg and +0.3 kg, respectively, over the 6-month experimental period. Treatment group and control group
