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 Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).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.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Effects of an Integrated Mobile Application with Telemedicine on Weight Management and Health Behaviors in Obese Adults: A Pilot Study
ABSTRACT
Background:
Obesity is associated with numerous health issues, and early identification and intervention in high-risk individuals can improve prognosis.
Objective:
This study evaluated the impact and effectiveness of an integrated health management program on the weight of individuals with obesity.
Methods:
We retrospectively collected case management data from 97 individuals with obesity (≥20 years) who received weight management care between September 1, 2023, and April 30, 2024. Exclusions included weight-loss medications, surgery, and other weight-loss programs. Data comprised patient demographics, medical history, health behaviors, and physical examination results. Follow-up data were obtained from a health management platform and hospital database. Statistical analyses used paired t-tests, Wilcoxon signed-rank tests, and generalized estimating equations (GEE).
Results:
The 2-month completers achieved a greater weight loss (−0.87 ± 1.35 kg) than 1-month completers (−0.03 ± 0.75 kg; p < 0.001). Health behavior scores improved at both time points (all p < 0.001), and step counts increased 8.9-fold overall and 10.5-fold among 2-month completers (p < 0.001). Among 2-month completers, those engaging in ≥3 program components had a lower adjusted weight (86.0 ± 1.6 kg) than those engaging in <3 program components (89.3 ± 1.7 kg; F = 6.09, p = 0.017). GEE models showed that ≥3-component engagement increased odds of weight loss by 16.6-fold at 1 month and 23.2-fold at 2 months.
Conclusions:
Weight loss improved in a dose-dependent manner, with ≥3-component engagement showing the strongest effects. Long-term studies with booster contacts are needed to validate the sustained benefits of our integrated health management program. Clinical Trial: none
