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 objective of this study was to determine the optimal number and type of casual (spot)
urine specimens required to estimate an individual's urinary sodium/potassium (Na/K) ratio …

The commonly used methods of estimating the 24-h urinary sodium (UNa) and urinary
potassium (UK) from spot urine (SU) are the Kawasaki method (K-method), INTERSALT …

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 …

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 …

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 …

Objectives: We undertook descriptive epidemiology of spot urine sodium-to-potassium ratio
(Na/K) in a population sample to clarify the close relationship between Na/K and blood …

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 …

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 …

Previous studies have reported a positive association between the urinary sodium-to-
potassium (Na/K) ratio and hypertension, and multiple measurements of the casual urinary …
