简要总结
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.
详细描述
The specific aims of this research project are to:
- Develop a targeted delivery system for mobile health messages which focused on improving physical activity and diet, and setting healthy resolutions each week.
- Deliver the M-TRIMM intervention, which encourages healthy behavior and the weekly renewal of health resolutions.
- Evaluate the effectiveness of this intervention on individuals' weight loss, self-efficacy, and motivation to sustain changes in lifestyle behaviors.
- Assess the benefit of receiving the message content only (in a paper document), versus a scheduled weekly delivery via mobile messaging.

盲法说明
Participants were randomized after they completed the study's baseline assessment. The randomization sequence was designed to balance treatment groups by gender of the participants. Allocation was concealed from the data collectors, and was determined using a randomization module in REDCap, a survey website. The data collectors were not blinded to the randomization results after the completion of the baseline survey.

研究组 & 干预措施
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.

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.
