Brief Summary

This study, involves the implementation and evaluation of a Monday-focused, individually tailored mobile health application to assist overweight or obese adults who would like to achieve a healthful weight. The goal was to evaluate the application of a Monday-focused delivery system for the M-TRIMM2 intervention on participants who worked or lived in areas in or adjacent to Johns Hopkins East Baltimore medical campus.Targeting mobile messaging occurred at strategic intervals throughout each week, with the intent of prompting participants to renew their health resolutions each Monday combined with lifestyle behavioral education.

Detailed Description

The specific aims of this research project are to:

1. Develop a targeted delivery system for mobile health messages which focused on improving physical activity and diet, and setting healthy resolutions each week.

2. Deliver the M-TRIMM intervention, which encourages healthy behavior and the weekly renewal of health resolutions.

3. Evaluate the effectiveness of this intervention on individuals' weight loss, self-efficacy, and motivation to sustain changes in lifestyle behaviors.
