description | High blood pressure (HBP) is the main modifiable cardiovascular risk factor. HBP can be related to high salt intake. To measure intake, not all feeding surveys are comparable and valid. The reference procedure for assessing salt intake consists of measuring the urinary excretion of sodium in urine collected during 24 hours, although alternative methods have been proposed, such as the collection of punctual and timed urine samples. In this review, we analyze which instruments allow the assessment of salt intake and which of them have provided greater validity and reliability through studies of concordance with the elimination of sodium in urine. Current food consumption surveys are inadequate because of their wide variability and relatively low correlation with the elimination of sodium in 24-hour urine. Its main limitation is the need for validation in different population groups. In primary care, salt intake should be assessed by using frequency-of-consumption questionnaires that collect foods with a high salt content, the consumption of preprepared dishes and questions that quantify the addition of salt in the preparation of food or at the table. For the validation of these questionnaires, the standard gold elimination of 24-hour urine sodium adjusted according to creatinine clearance should be used. |
