Location Initiated Individualized Texts for African American Adolescent Health

简要概况

The goal of this project is to test whether the mobile application helps Black adolescents make healthy food choices at the point of purchase.

详细说明

The epidemic of excess weight in childhood is impacted by exposure to, and consumption of, fast food and calorie dense foods prepared outside of the home. Black youth are more likely than their peers to live in communities with a high density of fast food restaurants. There is a need for interventions to help adolescents make healthy choices in these obesogenic environments. Previous research revealed that adolescents welcomed health-related text messages (based on Self Determination Theory and Motivational Interviewing) if they viewed them as personally relevant and if they were received at times when they faced dietary choices. Based on these findings, the following is hypothesized: that delivering messages (tailored to users' preferences and values) at a time and place when they are making a dietary choice (e.g., in a restaurant) will positively influence their choices. Thus, the Location Initiated Individualized Texts for African American Adolescent Health (LIITA3H) mobile application was developed. This app identifies when users were in a restaurant, automatically sends culturally relevant messages (based on focus group input from the target population) tailored to user preferences and the menu options at their location with the aim of prompting users to make a healthy choice, and allows users to submit an annotated photo response about their food choice. For this R21 project the following will be achieved: 1) the LIITA3H app will be enhanced by incorporating user input regarding its design and by allowing greater automation in the identification of eating venues, and 2) the impact of the app on the number of visits by users to restaurants, and on the number of calories users consume from these venues will be tested. This will provide data regarding effect size and will form the foundation for a large randomized trial in a larger population and including a greater range of eating venues. A better understanding of how 'just in time" personalized cues to action, made possible by new location-based technology, might alter behavior among a high risk population, will help future efforts to address obesity and other illnesses impacted by lifestyle choices.

Other: LIITA3H App with ELI, SNAP, and POP
This is the full version of the LIITA3H mobile app that will use the Enhanced Location Identification (ELI) technology to identify when a user is in an eating venue and then deliver culturally and individually tailored point of purchase prompts (POP) to encourage healthy choices and will allow participants to take pictures of the food they purchase using the Self-report of Nutrients with Annotated Photos (SNAP) function.
Other: LIITA3H App with ELI and SNAP
This is a version of the LIITA3H mobile app that will track participants' location and allow them to submit photos of their food.
Other: LIITA3H App with ELI only
This is a version of the LIITA3H mobile app that will only track participants' location.

研究工具

Experimental: Intervention Group 1 ELI, SNAP, and POP
Participants with have the app on their phone and it will track their visits to fast food restaurants, they will receive tailored text messages to prompt healthy choices when they are in a fast food restaurant and they will be asked to submit pictures of their food. This will be accomplished using the LIITA3H App with ELI, SNAP and POP
Active Comparator: Control Group 2 ELI and SNAP
Participants with have the app on their phone and it will track their visits to fast food restaurants and they will submit pictures of their food. However, they will not receive tailored text messages. This will be accomplished using the LIITA3H App with ELI and SNAP.
Other: Control Group 3 ELI only
Participants with have the app on their phone and it will track their visits to fast food restaurants but they will not receive tailored messages or submit pictures of their food. This will be accomplished with the LIITA3H App with ELI only.
