Key result
A review of 29 studies on population sodium intake and 13 prospective cohort studies supports the continued use of 24-h urine collections for assessing sodium intake despite logistic challenges.
Why the study?
What are the current approaches and challenges in using urine biomarkers to assess sodium intake?
What are the current approaches and challenges in using urine biomarkers to assess sodium intake?
This review reinforces 24-hour urine collection as the standard for assessing sodium intake in research, while highlighting the need for alternative modeling approaches due to logistical barriers.

Supports 24-h urine as sodium assessment standard; leaves open validation of single- vs multiple-collection protocols in cohorts.
Cogswell et al. (2015) conducted a review in Sodium intake assessment. 24-h urine collections was evaluated. A review of 29 studies on population sodium intake and 13 prospective cohort studies supports the continued use of 24-h urine collections for assessing sodium intake despite logistic challenges.
