NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Background:

Technology and in particular, access to the Internet, from a mobile device, has forever changed the way we relate and execute our own behavior. In recent years, studies have been carried out to analyze the effectiveness of different actions via smarthpone in the field of health, telephone calls, SMS, telemedicine and, more recently, the use of PUSH notifications. We continue to explore ways to increase user interaction with mobile applications, one of the pending subjects in the field of mHealth. By analyzing the data that subjects produce during a clinical trial, we can extract patterns of behavior and design effective protocols in weight loss programs.

Objective:

For all of the above, a clinical trial is proposed to evaluate (1) the efficacy of PUSH notifications in an intervention aimed at improving the body composition of adult women who are overweight or obese, through a dietary intervention, (2) analyze the evolution of body composition based on PUSH notifications and prescribed physical activity.

Methods:

A randomized clinical trial of 3 groups was conducted. All received the same attention in face-to-face consultation, with a frequency of 30 minutes per week, for 6 months. All patients are fitted with an APP designed for this study and a pedometer. The control group does not have access to functionalities related to self-control of weight at home or gamification or prescription of physical activity. The intervention groups are assigned objectives to achieve in the degree of compliance with diet and physical activity, through exclusive access to specific functionalities of the APP. For the analysis of three or more means the ANOVA of repeated means was used to evaluate the effects of the intervention at baseline, at 3 and at 6 months.

Results:

Receiving notifications during the intervention increase the weight that is lost (ßestand. = -0.208) and helps maintain or gain muscle mass (ßestand. = 0.266). However, the most important impact is observed on body fat, increasing its loss to a large degree (ßestand. = -0.397).

Conclusions:

Based on these results, it is possible to conclude the positive effects of PUSH technology on mHealth interventions. Future interventions should extend the period of time of the tests and research the impact that different contents of the messages, times and frequencies of sending them have.

ClinicalTrial:

ClinicalTrials.gov registration identifier NCT03911583
