Effect of a Multi-component Education Program on Salt Reduction in Adults
In Brief
A clinical study evaluating Salt reduction program and Healthy lifestyle program for Blood Pressure and Hypertension. Completed, enrolled 311 participants across 2 sites.
Detailed Summary
Excess salt intake is a major contributor to high blood pressure, the leading individual risk factor for cardiovascular events, such as stroke, myocardial infarction and heart failure. According to PHYSA study, salt intake in Portugal remains much higher (10.7 g) than recommended by the international health organisations, indicating the need for effective implementation of salt reduction interventions. In Portugal the main source of daily salt intake is added salt during cooking, and salt content in bread, cheese and processed meat. The objective of this study is to determine the effectiveness of a dietary education program tailored for salt reduction. To assess the effectiveness of the salt reduction program the investigator's will measure changes in salt consumption levels, by evaluating the 24 h urinary sodium excretion. This study is a consortium-initiated, randomised, simple-blinded, controlled trial designed to assess the effectiveness of a salt reduction program versus generic healthy lifestyle program in the Lisbon Metropolitan Area.
