Technology
Project Overview +
High
dietary sodium intake is linked to incident hypertension, stroke, heart failure
and kidney disease. U.S. federal guidelines advocate daily sodium intake of
less than 2,300 milligrams (mg) with further reduction to 1,500 mg in persons
who are 51 and older and those of any age who are African American and/or have
hypertension, diabetes, or chronic kidney disease. The estimated average sodium
intake for Americans is 3,400 mg per day.
In recent years,
consumption of pre-processed and restaurant foods has substantially increased,
and more than 75% of sodium in the average U.S. diet now comes from these
sources. The important gap is that most patients prescribed a low sodium
diet either do not understand or have information about the sodium content of
the foods they eat, and current IT approaches to reduce sodium intake focus
solely on counting the amount of dietary sodium eaten. Therefore, there is a critical
need to develop technologies that provide just-in-time information about
low sodium choices in both grocery stores and restaurants with an overall goal
to improve the ability to reduce dietary sodium intake.
LowSalt4Life is an app designed to provide education, assistance, and support to
people who are trying to reduce their sodium intake. It includes actionable
push messages to promote adherence to a low sodium diet, and was developed
using information derived from focus groups. The goal is to demonstrate the
effectiveness of the mobile application in reducing sodium intake in
participants with hypertension.
Aims +
The
long-term goal is to develop successful strategies that are driven by
adaptive technologies to support self-management in cardiovascular conditions. As
part of the long-term goal, a mobile application will be developed that incorporates
geofencing technology and provides just-in-time mobile push messages at the 2
main locations hypertensive individuals interact with processed and prepared
foods, at a grocery store or eating at a restaurant. Geofencing technology
allows the mobile application to be aware of the user’s location and provide
location-specific messages, vital for the just-in-time nature of the
intervention.
The
central hypothesis is that a mobile application with geofencing based
just-in-time push messages will help hypertensive patients reduce dietary
sodium intake and feel more confident in following a low sodium diet. The
rationale for this project, supported by the preliminary data, is that patients
need immediate information about low sodium dietary options in the places they
make most food choices - grocery stores or restaurants.
Aim 1: Establish a geofencing based adaptive notification message
system for the mobile application using participant feedback to facilitate
reducing dietary sodium intake.
Aim 2: Determine the effectiveness of the newly developed mobile
application on dietary sodium intake and on confidence in following a low
sodium diet.
Participants +
Participants will be
greater than 18 years of age and have a diagnosis of hypertension. They must be
on antihypertensive therapy for at
least 3 months, with stable antihypertensive therapy (medication type and dose)
for at least 2 weeks. They must own and use an Apple iPhone and have a daily sodium intake of >2,300 mg, as
estimated by a Food Frequency Questionnaire.
Intervention +
The intervention with
the mobile application includes three parts: 1) just-in-time contextual push
notifications that promote behavior change when a participant enters a grocery
store and restaurant; 2) the ability to easily scan the foods at grocery stores
to find options containing lower sodium content; 3) providing low sodium
alternatives to the participant’s top 5 high sodium foods.
