Abstract
Hypertension is a major public health problem in the U.S. Salt sensitivity is an important factor associated with hypertension and its complications, yet it has not been addressed in the nursing literature. Salt sensitivity is a directionally appropriate rise or fall in blood pressure when salt is added or removed, respectively. The change in blood pressure in salt-sensitive subjects occurs to a degree exceeding random blood pressure fluctuations. Salt sensitivity is present in 30% of normotensive and over 50% of hypertensive persons. It is more prevalent among African Americans, older persons, and individuals with renal insufficiency or diabetes. This paper provides nurses with an overview of salt sensitivity and its significance in hypertension. It presents conceptual and operational definitions of salt sensitivity, identifies factors contributing to its development, and describes implications for nursing practice.
