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.

4. Assess the benefit of receiving the message content only (in a paper document), versus a scheduled weekly delivery via mobile messaging.

Study Groups

Intervention Group - Receiving Text Messages

The 16-weeks text-messaging intervention centered around 8 goal topics: eating only when hungry, increasing PA, eating a lower fat diet, eating less sugar and reducing calories from beverages, exercising more, eating a balance diet, portion control, and making healthier food choices in social situations.

Messaging

Sun evening: asked to pick 1 of 3 goal topics

Mon morning: received a goal to focus on for the week

Mon evening: asked whether plans were made to reach the goal

Wed morning: received a tip to help reach goal

Wed evening: reminded that if having cravings, text "tip" to automatically receive a tip

Fri morning: received end of the week congratulations, encouragement to keep goals in mind over the weekend

Fri evening: asked for weight, congratulated if lost weight, or encouraged if no weight lost

Educational Materials

Intervention Type: BEHAVIORAL

After the baseline assessment and the 1st follow-up (\~8 weeks post randomization), participants received educational materials regarding physical activity and healthier diets. The study staff reviewed these materials with the participants

Control Group - Written Messages

Participants in the control group, received a printed copy of the same messages that the intervention group received. However, the first eight-weeks' worth of messages and craving tips were given after the baseline assessment, and the rest were given after the first follow-up assessment (~ 8 weeks post randomization).

The messages for each week were clearly laid out and labeled. Participants were given spaces to record their answers (i.e. to which goal they were selecting for each week). The study staff reviewed the first week's messages together with the study participants to get the participants comfortable with the format that the printed messages were presented in.
