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 Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).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Warning: This is an author submission that is not peer-reviewed or edited.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.
Effectiveness of digital health interventions on community health care among middle-aged and elderly population in Taiwan: 6-month cluster randomized trial
ABSTRACT
Background:
The aging population and increasing burden of chronic diseases underscore the need for effective community-based health management strategies. This study aimed to evaluate the clinical effectiveness of digital health interventions on health outcomes among community-dwelling middle-aged and elderly adults in Taiwan.
Objective:
This study aimed to evaluate the effectiveness of a digital health intervention using smart devices and physician feedback on health outcomes among community-dwelling middle-aged and elderly adults in Taiwan.
Methods:
Four communities in Taoyuan City, Taiwan, were voluntarily recruited. Eligible participants were adults aged ≥50 years who had resided in the community for at least six months. Of the 308 individuals assessed for eligibility, 199 provided informed consent and completed baseline evaluations. During the 6-month intervention period, participants used smart devices to collect monthly physiological data, which were automatically synchronized with a centralized health management platform. Physicians reviewed the data monthly and provided personalized consultations and health education. Primary outcomes—assessed at baseline, 3 months, and 6 months—included anthropometric measures, biochemical indices, electrocardiograms, and health-related questionnaires.
Results:
After 6 months, significant improvements were observed in the proportion of participants with abnormal indicators: blood pressure (53.67% to 34.46%; P<.001), blood glucose (55.93% to 37.85%), uric acid (22.60% to 7.34%; P<.001), total cholesterol (1.69% to 0.00%), BMI (44.07% to 40.11%; P<.001), body fat percentage (62.15% to 55.37%; P<.001), visceral fat rating (42.94% to 39.55%; P<.001), skeletal muscle mass index (4.52% to 2.82%; P<.001), poor self-rated health (11.30% to 5.65%; P<.001), and poor sleep quality (50.28% to 40.11%; P<.001).
Conclusions:
The use of cloud-integrated smart devices for community health promotion significantly improved both physical and mental health outcomes in middle-aged and elderly residents.
