Systematic review of studies comparing 24-hour and spot urine collections for estimating population salt intake.
OBJECTIVE To examine the usefulness of urine sodium (Na) excretion in spot or timed urine samples to estimate population dietary Na intake relative to the gold standard of 24-hour (h) urinary Na. METHODS An electronic literature search was conducted of MEDLINE (from 1950) and EMBASE (from 1980) as well as the Cochrane Library using the terms "sodium," "salt," and "urine." Full publications of...

متن کاملComparisons of spot vs 24-h urine samples for estimating population salt intake: validation study in two independent samples of adults in Britain and Italy.
OBJECTIVES To assess the reliability and reproducibility of estimations of group mean 24-h urinary sodium (Na) excretion through timed spot urines compared to 24 h urinary Na output in two independent cross-sectional population samples including men and women and different ethnic groups. METHODS AND RESULTS Study 1 was carried out in Britain and included 915 untreated 40-59 yrs male and femal...
متن کاملEstimation of salt intake from spot urine samples in patients with chronic kidney disease
BACKGROUND High salt intake in patients with chronic kidney disease (CKD) may cause high blood pressure and increased albuminuria. Although, the estimation of salt intake is essential, there are no easy methods to estimate real salt intake. METHODS Salt intake was assessed by determining urinary sodium excretion from the collected urine samples. Estimation of salt intake by spot urine was cal...
متن کاملModified Sampling Strategies Using Correlation Coefficient for Estimating Population Mean
This paper proposes two sampling strategies based on the modified ratio estimator using the population mean of auxiliary variable and population correlation coefficient between the study variable and the auxiliary variable by Singh and Tailor (2003) for estimating the population mean (total) of the study variable in a finite population. A comparative study is made with usual sampling strategies...
