We examined the reliability of dietary salt-sensitivity testing by repeatedly studying the effects of a high (220 mmol/day) and low (20 mmol/day) salt diet in 15 normotensive subjects. Reliability of classification of salt-sensitivity as described by the kappa statistic was 0.87 implying an almost perfect strength of agreement between the two parts of the study. Whereas only 20% of the subjects with negative familial histories of hypertension were salt-sensitive, this was the case with 68% of the subjects with positive familial histories. Our results show that salt-sensitivity can be reliably tested in normotensive subjects and that it is related to a familial history of hypertension.
我们通过反复研究高盐饮食（220毫摩尔/天）和低盐饮食（20毫摩尔/天）对15名血压正常受试者的影响，检验了膳食盐敏感性测试的可靠性。用kappa统计量描述的盐敏感性分类可靠性为0.87，这意味着该研究的两部分之间存在几乎完美的一致性。虽然高血压家族史阴性的受试者中只有20%对盐敏感，但高血压家族史阳性的受试者中这一比例为68%。我们的结果表明，盐敏感性在血压正常的受试者中可以得到可靠的检测，并且它与高血压家族史有关。
