【摘要】 本文是在同一个县内调查了一个长期喝盐茶的地区和一个不喝盐茶地区农民的血压及24小时尿钠、钾排出量。发现:一、盐茶区农民平均尿钠排出量明显高于非盐茶区,平均高55.5毫克当量/日(p<0.01)。同样,盐茶区农民的收缩压,舒张压,平均压水平亦明显高于非盐茶区,平均分别高7.1、6、6.2毫米汞柱(p<0.01)。二、尿钠排出量与收缩压呈正相关(p<0.01)。更多还原

【Abstract】 In order to study the relationship between salt uptake and hypertension,weinvestigated the blood pressure and the amount of 24-hr urinary sodium excretionin peasants of two nearly villages,the peasants of one village had the habit ofdrinking salt-tea,while those of the other hadn’t.Other conditions were comparable,we found out:(1)The mean of 24-hr urinary sodium excretion of the peasants in the salt-teataking area was 55.5meq,which was significantly higher than that of the non-salt-tea taking area (P<0.01),the mean of systolic pressure,diastolic pressure and average,pressure of the peasants in the former area were also higher than those of the latterby an average of 7.1,6.0,6.2 mmHg respectively (p<0.01).These results tallied with most of epidemiologic investigations on this problemboth abroad and at home,these data supported that the risk of hypertension and/or thelevel of blood pressure in high salt uptake areas were higher than those of low salttaking areas.(2)A positive correlation between the amount of urinary sodium excretionand systolic blood pressure was obtained (P<0.01).(3)Multifactor progressive regression analysis showed that whether in salt-tearegion or in non-salt-tea region,the age and the ratio of sodium/potassium in urineof the peasants could always be selected into the diastolic blood pressure and the meanblood pressure regression equation.更多还原
