Objective: To assess the relationship between dietary sodium intake, as measured by urinary electrolyte excretion, and blood pressure within a population of older Australian adults.
Design, Setting And Participants: A cross-sectional study of adults enrolled in the Melbourne Collaborative Cohort Study, stratified by sex, country of birth (Italy, Greece, Australia/New Zealand) and age (50-59 and 60-75 years). Blood pressure measurements were taken in 2003-2007 and 24-hour urine collections in 2007-2008. Read More

Background: Data regarding the association between 24h urinary sodium and potassium excretion with kidney outcomes in patients with diabetes mellitus is currently scarce.
Methods: We conducted a single-center, retrospective cohort study in which 1230 patients with diabetes who had undergone a 24h urinary sodium and potassium excretion test were analyzed. Patients with incomplete urine collection were excluded based on 24h urinary creatinine excretion. Read More

Background: Although groups of African descent are particularly sensitive to blood pressure (BP) effects of salt intake, the role of obesity and insulin resistance in mediating this effect is uncertain. We determined whether obesity or insulin resistance is independently associated with urinary Na(+)/K(+)-BP relationships in a community sample of African ancestry.
Methods: We measured 24-hour urinary Na(+)/K(+), homeostasis model assessment of insulin resistance (HOMA-IR), and nurse-derived conventional and 24-hour ambulatory BP in 331 participants from a South African community sample of black African descent not receiving treatment for hypertension.

The 24-hour urinary excretion of sodium, potassium, calcium, and magnesium and their relationship to arterial blood pressure were investigated from December 1983 to May 1984 in a 10% random sample (n = 666) of urban Bantu of Kinshasa, Zaïre. In youths aged 10-19 years, blood pressure averaged 109/60 mmHg, and the 24-hour urinary excretion of sodium, potassium, calcium, and magnesium averaged 84 mmol, 30 mmol, 483 mumol, and 2 mmol, respectively. After adjustment for age and body weight, a weak positive association became apparent between diastolic pressure and the urinary sodium to potassium ratio in girls and all youths. Read More
