Food Frequency Questionnaire to Assess Sodium Intake

Conditions studied

Hypertension, Renal Insufficiency

About this study

EvalSel can precisely assess the salt intake of hospitalized patients in nephrology and cardiology or in medical consultation. It can determine salt consumption to the nearest gram. The objectives of this food frequency questionnaire are to arrive at a precise dietary diagnosis and to quickly identify the dietary errors made by the patients. EvalSel is useful for doctors to quickly obtain an assessment of the salt consumption of their patients, so they can refer them to dietitians if necessary. It can be used on the day of admission to hospital or during medical follow-ups to know the evolution of their consumption over the long term and improve their care.

Interventions

• Other: Questionnaire — These patients complete the food frequency questionnaire in order to validate it for lower sodium consumptions. The experimental group has already received dietary advices regarding salt consumption during during their recent consultations.

Primary outcomes

• Intra-class correlation coefficient between the quantitative measurement of sodium consumption and the 24-hour natriuresis measurement and verification of the 24-hour creatininuria values (through study completion an average of 18 months)
