Description
Summary:Abstract only Background: The salt debate continues, also regarding the WHO recommendation to restrict salt intake below 5 g/day. Black populations exhibit a high prevalence of salt-sensitivity, but no large-scale studies in these populations have been performed to show the cardiovascular consequences of dietary salt intake. Aim: To determine whether estimated daily salt intake is associated with BP and renal function cross-sectionally; and prospectively over 5-years. Methods: We included 1589 HIV-uninfected black participants aged > 30 yrs, and followed 1174 over 5 years (of which 151 died). We collected blood and fasting morning spot urine. The Kawasaki-formula was applied to estimate 24-h urinary sodium excretion. Using ANCOVAs we compared the following salt-intake groups:
