Diversity Supplement: A Just-In-Time Adaptive Mobile Application Intervention To Reduce Sodium Intake And Blood Pressure In Hypertensive Patients

点击翻译按钮获取中文摘要

PROJECT SUMMARY High sodium intake is a significant public health problem associated with hypertension, which is associated with a greater risk of stroke, cardiovascular risk and death. Despite guidelines recommending less than 2,300 mg of sodium per day, the average sodium intake for the US population is approximately 3,400 mg per day. Interventions that lower sodium intake can decrease blood pressure and improve cardiovascular outcomes. The LowSalt4Life mobile health (mHealth) application provides a just-in-time adaptive intervention (JITAI) to lower sodium intake. This diversity supplement will support the research Aims and long-term career goals of an outstanding, early career scientist at the University of Michigan (Cornelius A. James, MD). Dr. James’ contributions to this study will make the findings more meaningful because they will provide insight into how to implement and operationalize an intervention with demonstrated efficacy. Specifically, Dr. James will conduct the following study entitled, “Clinician and Patient Attitudes toward a Prescribed Dietary Sodium Just-In-Time Adaptive Intervention: A Mixed Methods Study.” This supplement will seek to understand the attitudes of clinicians, and patients related to use of a low sodium dietary JITAI. This understanding may not only inform approaches to the improvement, development and implementation of the low sodium diet dietary JITAI, and other mHealth applications, but it will also support a promising early career scientist’s development.
