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)。 This article is in the same county to investigate the long-term drinking salt tea in the area and a non-drinking salt farmers peasants blood pressure and 24-hour urine sodium and potassium excretion. The results showed that: (1) The average urinary sodium excretion of farmers in salt-tea area was significantly higher than that of non-salt tea area (average 55.5 mg / d) (p <0.01). Similarly, systolic blood pressure, diastolic blood pressure and mean pressure were significantly higher in salt-tea farmers than in non-salt-tea farms, with an average of 7.1, 6 and 6.2 mm Hg respectively (p <0.01). Second, urinary sodium excretion was positively correlated with systolic blood pressure (p <0.01).
