Effects of a Novel Contextual Just-In-Time Mobile App Intervention (LowSalt4Life) on Sodium Intake in Adults With Hypertension: Pilot Randomized Controlled Trial.

Background: High dietary sodium intake is a significant public health problem in the United States. High sodium consumption is associated with high blood pressure and high risk of cardiovascular disease.

Objective: The aim of this study was to evaluate the effect of a just-in-time adaptive mobile app intervention, namely, LowSalt4Life, on reducing sodium intake in adults with hypertension.

Insufficient Calorie Intake Worsens Post-Discharge Quality of Life and Increases Readmission Burden in Heart Failure.

Objectives: The purpose of this study was to evaluate the relationship between calorie intake and post-discharge outcomes in hospitalized patients with heart failure (HF).

Background: Malnutrition increases adverse outcomes in HF, and dietary sodium restriction may inadvertently worsen nutritional intake.

Methods: In a dietary intervention trial, baseline nutritional intake in HF inpatients was estimated using the Block Food Frequency Questionnaire (FFQ), and the Nutritional Risk Index (NRI) was calculated.
