While the association between 24-h urinary sodium and potassium excretion with blood
pressure is well established, the relationships of these ions to spot urine measurements are …

Background Higher levels of sodium intake are reported to be associated with higher blood
pressure. Whether this relationship varies according to levels of sodium or potassium intake …

BACKGROUND Sodium intake is correlated with the development of hypertension. Guyton's
principals suggest that the 24-hour urinary sodium excretion reflects sodium ingestion over …

The usefulness of whole-day, daytime (waking to retiring time) and overnight urine samples
for assessing the relationship between blood pressure and sodium intake was examined in …

This study was done to clarify the optimal number and type of casual urine specimens
required to estimate urinary sodium/potassium (Na/K) ratio in individuals with high blood …

The Na/K ratio may be more strongly related to blood pressure and cardiovascular disease
than sodium or potassium. The casual urine Na/K ratio can provide prompt on-site feedback …

In order to estimate the salt and potassium intake in a population and to compare their
annual trends, we developed a simple method to estimate population mean levels of 24-h …

High sodium-to-potassium ratios are associated with elevated blood pressure levels and an
increased risk of cardiovascular diseases. We aimed to determine whether urinary sodium …

The 24‐hour urine collection method is considered the gold standard for the estimation of
ingested potassium and sodium. Because of the impracticalities of collecting all urine over a …

The sodium-to-potassium ratio (Na/K) of a urine sample is a simple index of salt loading. To
practically use Na/K, we aimed to determine whether the Na/K value affects blood pressure …
