Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? High sodium and low potassium in 24 h urinary excretion were associated with elevated blood pressure. WHAT IS ADDED BY THIS REPORT? With increasing body mass index levels, decreasing unit urinary sodium excretion was more effective in reducing systolic and diastolic blood pressure, and increasing unit urinary potassium excretion was more effective in reducing diastolic blood pressure. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Reducing sodium and increasing potassium intake was more effective in reducing blood pressure in overweight and obese non-hypertensive adults compared to underweight and normal weight adults.
