Validation of spot urine in predicting 24-h sodium excretion at the individual level
24-hour urine sodium intake spot urine validation formula
2018/11/14
Background: Evidence for the effect of dietary sodium intake on the risk of cardiovascular disease has been controversial. One of the main explanations for the conflicting results lies in the great va...
Reproducibility of urinary biomarkers in multiple 24-h urine samples
biomarker bisphenol A reproducibility sodium 24-h urine sample
2018/11/12
Background: Limited knowledge regarding the reproducibility of biomarkers in 24-h urine samples has hindered the collection and use of the samples in epidemiologic studies.
Objective: We aimed to eva...
The role of obesity in the relation between total water intake and urine osmolality in US adults, 2009–2012
effect modification hydration status NHANES obesity water intake
2018/12/19
Background: Adequate water intake is critical to physiologic and cognitive functioning. Although water requirements increase with body size, it remains unclear whether weight status modifies the relat...
Comparing metabolite profiles of habitual diet in serum and urine
metabolomics metabolite serum urine diet food nutrition assessment biomarker
2018/12/14
Background: Diet plays an important role in chronic disease etiology, but some diet-disease associations remain inconclusive because of methodologic limitations in dietary assessment. Metabolomics is ...
The void in using urine concentration to assess population fluid intake adequacy or hydration status
dehydration fluid needs hydration assessment hypohydration hypovolemia
2018/12/13
Urine concentration can be used to assess fluid intake adequacy or to diagnose dehydration. However, too often urine concentration is used inappropriately to draw dubious conclusions that could have h...
Feasibility of collecting 24-h urine to monitor sodium intake in the National Health and Nutrition Examination Survey
24-hour urine sodium excretion NHANES biomarker hypertension sodium intake
2018/12/13
Background: Twenty-four–hour urine sodium excretion is recommended for monitoring population sodium intake. Because of concerns about participation and completion, sodium excretion has not been collec...
Spot urine sodium measurements do not accurately estimate dietary sodium intake in chronic kidney disease
24-hour urine chronic kidney disease sodium intake spot urine hypertension cardiovascular disease
2018/12/3
Background: Sodium intake influences blood pressure and proteinuria, yet the impact on long-term outcomes is uncertain in chronic kidney disease (CKD). Accurate assessment is essential for clinical an...

Preexercise Urine Specific Gravity and Fluid Intake During One-Hour Running in a Thermoneutral Environment – A Randomized Cross-Over Study
Hydration urine specific gravity exercise gender gastrointestinal discomfort
2015/5/5
Urine specific gravity is often used to assess hydration status. Athletes who are hypohydrated prior to exercise tend to ingest more fluid during the exercise, possibly to compensate for their pre exe...
