Validez y limitaciones de los métodos para medir la ingesta y la eliminación de sal

摘要: 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 intake consists of measuring urinary excretion sodium in urine collected during 24hours, although alternative methods have been proposed, such as collection punctual timed samples. In this review, we analyze which instruments allow assessment them provided greater validity reliability through studies concordance with elimination urine. Current food consumption inadequate because their wide variability relatively low correlation 24-hour Its limitation need validation different population groups. primary care, should assessed by using frequency-of-consumption questionnaires that collect foods a content, preprepared dishes questions quantify addition preparation or at table. For these questionnaires, standard gold adjusted according creatinine clearance used.
