## Content

Published in *Journal of Medical Internet Research* (JMIR), 2025, e69466. Also published in *Diabetes, Obesity and Metabolism* (Wiley, doi: 10.1111/dom.70244) as "Digital engagement enhances dual GIP/GLP-1 receptor agonist and GLP-1 receptor agonist efficacy."

PMC archive: PMC11997532.

**Study design:** Retrospective cohort service evaluation of a digital weight management platform integrated with GLP-1 therapy (both semaglutide and tirzepatide). Compares engaged vs. non-engaged participants.

**Key findings:**
- At month 5: **Engaged participants: 11.53% mean weight loss** vs. **non-engaged: 8%** — a 3.5 percentage point advantage from digital engagement
- Digital platform: live group video coaching, text-based in-app support, dynamic educational content, real-time weight monitoring, medication adherence tracking
- Real-world data: "roughly half of users stopping within a year" but persistence improves to 63% when supply and coverage issues addressed

**Related finding (Danish study, previously documented):**
- Online weight-loss program + semaglutide at half typical dose → 16.7% weight loss over 64 weeks
- Equivalent outcomes at half the drug dose with behavioral support

**2026 context:**
- Oral semaglutide FDA-approved for weight management (2026) — may improve adherence via non-injection route
- "2026 is the year GLP-1s grow up" (MM+M) — shift from prescription volume to outcomes metrics and adherence management

## Agent Notes

**Why this matters:** This is US real-world data (not Danish controlled study) confirming the digital engagement effect on GLP-1 outcomes. The 11.53% vs. 8% difference (3.5pp advantage) is clinically meaningful — equivalent to one additional dose level in many GLP-1 titration protocols. Under capitated payment models (VBC), this difference could determine whether GLP-1s are cost-saving or cost-additive for a population.

**What surprised me:** The study covers BOTH semaglutide and tirzepatide, showing the digital engagement effect generalizes across the GLP-1/GIP class. This isn't just a semaglutide story; behavioral support amplifies both molecules.

**What I expected but didn't find:** Evidence that specific behavioral support components (coaching vs. monitoring vs. education) drive the effect differentially. The study doesn't disambiguate which platform element drives the 3.5pp advantage. The Danish study's insight (half-dose = equivalent outcomes) was more mechanistically useful.

**KB connections:**
- Extends and confirms the Danish study finding (previously documented in Session 4) with US real-world data
- Strengthens Belief 4 (atoms-to-bits) — behavioral/digital support ("bits") amplifies GLP-1 efficacy ("atoms"), confirming the defensible value layer thesis
- Connects to the GLP-1 adherence paradox (Session 3): MA plans restrict access despite downstream savings; this data shows the magnitude of lost savings from non-engagement
- The 63% persistence when supply/coverage issues resolved → the access barrier (OBBBA Medicaid cuts) is a direct threat to realizing these outcomes at population scale
- Oral semaglutide FDA approval for weight management (2026) = potential adherence improvement; this is a new data point not in prior sessions

**Extraction hints:**
- This is a confirmation of the Session 4/5 Danish study finding — update existing claim with US real-world corroboration
- New claim candidate: "Oral semaglutide's 2026 FDA approval for weight management may reduce the adherence gap that makes GLP-1 economics fragile under capitation, by eliminating injection barriers for self-pay and telehealth populations"
- The atoms-to-bits framing: "Digital engagement produces 3.5pp additional weight loss vs. GLP-1 alone in real-world US populations — the 'bits' layer amplifies the 'atoms' layer, making behavioral platform integration the value driver in a commoditizing drug market"

**Context:** JMIR is a high-volume digital health journal; the Diabetes, Obesity and Metabolism (Wiley) publication gives it endocrinology/obesity journal credibility. Retrospective cohort design (not RCT) — selection bias possible (engaged users may be more motivated), but real-world operational data.

## Curator Notes
PRIMARY CONNECTION: Belief 4 atoms-to-bits + Session 4/5 GLP-1 adherence thread
WHY ARCHIVED: US real-world confirmation of Danish study finding; adds data point for oral semaglutide FDA approval as a potential adherence game-changer
EXTRACTION HINT: Update existing GLP-1 adherence claim with US real-world data; create new claim for oral semaglutide adherence pathway if not already in KB
