Brief Summary:
This a single-center prospective randomized controlled trial. Subjects will be assigned to the standard of care dietary recommendations for a low sodium diet (LSD) vs. the standard of care dietary recommendations for a low sodium diet plus a mobile application that analyzes sodium content of shopping lists that are created prior to shopping trips to the grocery store over an 8-week study period. An initial pilot phase will be done to ensure adequate percentage of subjects are completing the study in the intervention group and that adequate data is being collected.
Detailed Description:
The study will be designed as a single-center prospective randomized controlled trial. Subjects will be assigned to the standard of care dietary recommendations handout vs a mobile application that analyzes sodium content of shopping lists that are created prior to shopping trips to the grocery store. The intervention will be administered for 8 weeks. The trial will be split into two phases, 1) Pilot phase, and 2) Trial phase. Once we have enrolled 20 subjects in the intervention arm, we will analyze whether an appropriate percentage of subjects have completed the study and adequate data is being collected. At the end of the trial, outcomes will be measured as follows:
1. Mean change in score on a Knowledge of Low Sodium Diet validated questionnaire completed at baseline and at the end of the study (primary outcome)
\-- The minimum and maximum scores are 0 and 26, respectively. A higher score indicates a better knowledge of LSD and we hypothesize that use of the software application will result in a higher score on the questionnaire.
2. Mean change in urinary sodium measured on two baseline 24hr collections and two end of study 24hr collections (primary outcome)
\-- We hypothesize that an always-available application that helps guide subjects in grocery choices will decrease the 24hr sodium level compared to the control group
3. Within-group assessment of how often the Healthcart application is used to create shopping carts and recording of changes in shopping cart sodium score over the study period (secondary outcome)
\-- Healthcare interventions delivered via mobile applications are quite novel at this time and the data regarding uptake and usage is limited. These outcome measures will add to this body of data.
4. Clinical data (exploratory outcomes)
