The relationships between blood pressure and 24-h urinary sodium, potassium, calcium and magnesium were investigated in adult men and women constituting a random sample of urban Bantu of Zaire. Blood pressure and the 24-h urinary sodium, potassium, calcium and magnesium averaged 124 +/- 20/72 +/- 14 mmHg, 87 +/- 51 mmol, 33 +/- 19 mmol, 828 +/- 91 mumol and 1.9 +/- 1.6 mmol, respectively. After adjusting for sex, age, body weight and pulse rate, systolic pressure was significantly and positively correlated with urinary sodium in all subjects and in women taken separately; it was also negatively correlated with urinary potassium, while diastolic pressure was weakly associated with urinary calcium. When instead of the 24-h urinary sodium and potassium the sodium: potassium ratio was considered as an independent variable in multiple regression analysis, it was correlated with both systolic and diastolic pressure. Our results indicate that age, body weight, pulse rate, sex and the sodium: potassium ratio contribute to the prediction of systolic and diastolic blood pressure, while urinary calcium was only associated with diastolic pressure.
在构成扎伊尔城市班图人随机样本的成年男性和女性中，研究了血压与24小时尿钠、钾、钙和镁之间的关系。血压以及24小时尿钠、钾、钙和镁的平均值分别为124±20/72±14 mmHg、87±51 mmol、33±19 mmol、828±91 μmol和1.9±1.6 mmol。在对性别、年龄、体重和脉搏率进行校正后，收缩压在所有受试者以及单独的女性中均与尿钠显著正相关；它也与尿钾呈负相关，而舒张压与尿钙呈弱相关。当在多元回归分析中，将钠钾比而非24小时尿钠和钾视为自变量时，它与收缩压和舒张压均相关。我们的结果表明，年龄、体重、脉搏率、性别和钠钾比有助于预测收缩压和舒张压，而尿钙仅与舒张压相关。
