Sodium excretion and health-related quality of life: the results from the Korea National Health and Nutrition Examination Survey 2010-2011.

Low estimated 24-h urine sodium rather than high estimated 24-h urine sodium was associated with low HR-QOL in representative Korean adults. Further studies are warranted to verify the effect of sodium intake on HR-QOL and the adequate-level sodium restriction in terms of HR-QOL.
