What this Trial Is About
Researchers are evaluating a food frequency questionnaire called EvalSel to accurately measure salt intake in hospitalized patients with high blood pressure or chronic kidney disease stages 4-5, as well as patients seen in medical consultations. The goal is to provide a precise dietary diagnosis and quickly identify dietary mistakes related to salt consumption. This tool helps doctors assess patients' salt intake to inform better care and referrals to dietitians if needed. Participants complete the EvalSel questionnaire, which is designed to quantify sodium consumption to the nearest gram. The questionnaire is validated by comparing its results with 24-hour urine sodium measurements and creatinine values over an average follow-up period of 18 months. Patients in the experimental group have already received dietary advice about salt intake during recent consultations. During the study, participants' sodium intake is assessed through the questionnaire and verified with urine tests. The study tracks changes over time to monitor the evolution of salt consumption and improve patient management. The research team measures the correlation between questionnaire results and urine sodium levels to validate the tool's accuracy. The total duration includes follow-up assessments averaging 18 months.
