Abstract
Background: This study aimed to determine the association of 24-hour urinary sodium excretion levels with insulin resistance and metabolic syndrome among Korean adults.
Methods: In this study, nondiabetic subjects who participated in the 2010 Korean National Health and Nutrition Examination Survey were enrolled. The 394 subjects had 24-hour urinary sodium excretion levels of ≤2,300 mg/day; they were divided into 5 groups for analysis of their association with insulin resistance and metabolic syndrome.
Results: No significant differences were found between 24-hour urinary sodium excretion levels and insulin resistance and metabolic syndrome.
Conclusion: Urinary sodium excretion levels showed no significant associations with insulin resistance and metabolic syndrome among the Korean adults with urinary sodium excretion levels of ≤2,300 mg/day.
