A practical new method of measuring population salt intake

High blood pressure is a leading contributor to the global burden of disease, and salt reduction has been identified as one of the most cost-effective strategies for reducing blood pressure and vascular disease.
The World Health Organization (WHO) has set a target for all 194 Member States to reduce population salt intake by 30% by 2025.
In order to measure and track the changes in worldwide salt consumption, reliable and easily administered methods are required. The gold standard method for determining population salt intake is collection of 24-hour urine samples, which requires individuals to collect all of their urine for a 24-hour period.
However, this method is burdensome for subjects, can limit participation and affect the representativeness of participants in population surveys.
For these reasons identification of other robust methods of estimating population salt intake is a priority for WHO.
A promising alternative to 24-hour urine collection is using a single urine collection to estimate population salt intake. During this project, Dr Kristina Petersen will conduct an individual participant data meta-analysis, which will combine all of the already available data worldwide to provide robust evidence about the reliability of using a single urine collection to predict salt intake.
This project will generate high-level evidence that will be used by the WHO to inform their population surveillance of salt intake in all Member States
