Standard clinical advice for the prevention and treatment of hypertension includes limitation of salt intake. Previous studies of the association between perception of salt taste and hypertension prevalence have not reported consistent results and have usually been conducted in small study populations. The aim of this study is to determine the cross-sectional relationship among the intensity of salt taste, discretionary salt use, and hypertension. Subjects (n = 2,371, mean age = 48.8 years) were participants in the Beaver Dam Offspring Study, an investigation of sensory loss and aging conducted in 2005–2008. Salt taste intensity was measured using a filter paper disk impregnated with 1.0 M sodium chloride and a general Labeled Magnitude Scale. Hypertension was defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg or use of high blood pressure medication. Nearly 32% of the participants rated the salt disk as weak or having no taste, while approximately 10% considered it to be very strong or stronger. The intensity was reported to be less strong by men (P < 0.001) and college graduates (P = 0.02), and was inversely associated with frequency of adding salt to foods (P = 0.02). There was no significant association between hypertension and the intensity of salt taste, before and after adjustment for covariates. Exclusion of subjects with a history of physician diagnosed hypertension did not appreciably alter these findings. The perception of salt taste was related to the frequency of discretionary salt use but not to hypertension status or mean blood pressure.

在海狸坝后代研究中，盐味的强度与高血压的患病率无关。

预防和治疗高血压的标准临床建议包括限制盐的摄入量。以前关于盐味感知和高血压患病率之间关联的研究没有报告一致的结果，通常是在小型研究人群中进行的。本研究的目的是确定盐味强度、随意使用盐分和高血压之间的横断面关系。科目 ( n = 2,371，平均年龄 = 48.8 岁）是 Beaver Dam Offspring Study 的参与者，这是一项在 2005-2008 年进行的关于感觉丧失和衰老的调查。盐味强度使用浸渍有 1.0 M 氯化钠的滤纸盘和通用标记量级来测量。高血压定义为收缩压≥140 mmHg 或舒张压≥90 mmHg 或使用高血压药物。近 32% 的参与者认为盐盘很弱或没有味道，而大约 10% 的人认为它很浓或很浓。据报道，男性（P  < 0.001）和大学毕业生（P  = 0.02）的强度不那么强，并且与向食物中加盐的频率呈负相关（P = 0.02）。在调整协变量之前和之后，高血压与盐味强度之间没有显着关联。排除有医生诊断为高血压病史的受试者并没有明显改变这些发现。对盐味的感知与随意使用盐的频率有关，但与高血压状态或平均血压无关。
