Role of salt sensitivity, blood pressure, and hyperinsulinemia in determining high upper normal levels of urinary albumin excretion in a healthy adult population.

Background: The objective of this study was to investigate the role of blood pressure (BP), salt sensitivity (SS), and the cardiovascular metabolic syndrome in determining the urinary albumin excretion (UAE) in glucose-tolerant, normoalbuminuric (<20 mg/day) healthy adults.

Methods And Results: We evaluated 177 healthy subjects (age, 38.3 +/- 0.
