利用第一次国民健康与营养调查(NHANES I)数据，我们研究了膳食钠、钾和酒精与血压的关系以及膳食钙摄入量的关系。在低钙摄入量(男性为400 mg/d，女性为800 mg/d)下，在控制了年龄、体重指数(BMI)、种族和性别后，Na/K比率(Na：K)与血压(P<；0.01)显著相关。在钙摄入量较高的情况下，Na：K或任何其他营养物质(酒精除外)与收缩压或舒张压无关。Na：K与血压的关系比单独的营养素更强，低钙摄入量是Na：K-血压关系明显的必要条件。这三种饮食因素与血压的相互作用在所有种族和性别群体中都很明显。年龄、体重指数、性别和酒精与血压的关系不受钙水平的影响。
Using First National Health and Nutrition Examination Survey (NHANES I) data, we studied the relationships of dietary sodium, potassium, and alcohol to blood pressure in relation to levels of dietary calcium intake. At low Ca intakes (< 400 mg/d for men and < 800 mg/d for women) the ratio of Na to K (Na:K) was significantly related to blood pressure (p < 0.01) after controlling for age, body mass index (BMI), race, and gender. At higher Ca intakes neither Na:K nor any other nutrient (with the exception of alcohol) was related to either systolic or diastolic blood pressures. Na:K was more strongly related to blood pressure than either nutrient alone and low Ca intakes were necessary for the Na:K-blood pressure relationship to be evident. Interaction of these three dietary factors in relation to blood pressure was evident in all race and gender groups. Associations of age, BMI, gender, and alcohol with blood pressure were not affected by Ca levels.
