FOUR URINARY CATIONS AND BLOOD PRESSURE: A POPULATION STUDY IN TWO BELGIAN TOWNS

The relationship between blood pressure and the 24-hour urinary excretion of four cations (Ca, Mg, K, Na) was investigated in a random sample of 688 inhabitants of two Belgian towns. In 160 youths aged 10–19 years, systolic/ diastolic blood pressure averaged 118 ± 12.6/65 ± 8.6 mmHg (mean ± standard deviation) and the urinary excretion of the four urinary cations was broadly similar in both sexes. Adjusting for body weight removed the strong relationship between blood pressure and age, but a positive relationship between systolic pressure and pulse rate emerged. The only association between bl... Mehr ...
