Research summary
The aim of this research study is to measure dietary sodium intake in adults aged 19-64 years in England. This will be based on 24-hour urinary sodium excretion (in urine).
Assessment of salt intake cannot be reliably or accurately measured by dietary intake data. Analysis of the excretion of sodium in a 24-hour urine sample (consistent with previous studies) is considered appropriate and the most robust method.
Individuals will be recruited from a sample of Health Survey for England (HSE) 2017 respondents who consented to be contacted for future research. A minimum of 600 complete 24-hour urine samples is needed to detect a change in salt intake of 0.5g/day when compared with previous urinary sodium analyses. In order to achieve this 3311 individuals will be approached by letter and FAQ sheet (Document 1 and 2) and then telephone (Document 3). Participants who agree will be visited by a nurse and asked to collect all their urine for a 24-hour period.
The results will be used by Government to monitor progress towards the target to reduce the average population salt intake for adults to less than 6g per day and an anonymised dataset will be available to researchers via the UK data archive.
