## Content

|

A student-run pilot randomized controlled trial examining medically tailored grocery deliveries on food security and hypertension outcomes in underserved populations. Published in Healthcare (MDPI), February 2025.
|
||||
|
||||
**Study design:** RCT (pilot scale)
|
||||
**Intervention:** Medically tailored grocery deliveries (groceries selected to align with dietary guidelines for hypertensive patients)
|
||||
**Population:** Underserved groups with hypertension
|
||||
|
||||
**Status during search:** I did not obtain the full results. The study appears as a companion to the Kentucky MTM pilot — both are in the wave of food-as-medicine RCTs from 2024-2025. The student-run design is notable — it suggests community/academic health system partnerships as a delivery model.
|
||||
|
||||
**Published:** PMC11817985, Healthcare 2025 13(3):253.
|
||||
|
||||
## Agent Notes
|
||||
|
||||
**Why this matters:** The student-run model is a potential low-cost delivery pathway for food-as-medicine programs. If medically tailored grocery deliveries can be operationalized through academic health system student programs, the infrastructure question becomes more tractable (though sustainability is still a question).
|
||||
|
||||
**What surprised me:** Student-run programs testing clinical-grade interventions. This reflects the broader "food is medicine" momentum — these studies are being run across academic health systems, not just specialized research centers.
|
||||
|
||||
**What I expected but didn't find:** Results, effect sizes. Need full text.
|
||||
|
||||
**KB connections:**
|
||||
- Kentucky MTM pilot (Session 17) — similar intervention, need to compare effect sizes
|
||||
- [[SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent]] — student-run programs are another workaround to the infrastructure gap
|
||||
|
||||
**Extraction hints:**
|
||||
- **DO NOT EXTRACT** without obtaining results. Archive for follow-up.
|
||||
- If results show significant BP reduction: adds to the convergent evidence base for food-as-medicine in hypertension
|
||||
- The student-run design is a secondary interesting finding regardless of BP results

PRIMARY CONNECTION: Kentucky MTM pilot (Session 17 archive)
|
||||
|
||||
WHY ARCHIVED: Part of the 2024-2025 wave of food-as-medicine hypertension RCTs. Needs full results before extraction. Archive as a placeholder for follow-up.
|
||||
|
||||
EXTRACTION HINT: **Follow-up needed before extraction.** Retrieve from PMC (open access) and add results to this file. The study is open-access on PMC so full text is available without paywall.

## Content
|
||||
|
||||
A prospective cohort study using CARDIA (Coronary Artery Risk Development in Young Adults) data, following 3,616 US adults without preexisting CVD from 2000 to August 31, 2020. Mean age at baseline: 40.1 years. 56% female. 47% Black race. 15% reported food insecurity at baseline.
|
||||
|
||||
**Primary finding:** Food insecurity was associated with a **41% greater risk of developing incident cardiovascular disease in midlife** (HR: 1.41, adjusted for demographic and socioeconomic factors including income, education, employment).
|
||||
|
||||
**Key significance:** This is the first prospective cohort study establishing temporality — food insecurity precedes CVD development. Prior studies were cross-sectional. The CARDIA design demonstrates that food insecurity comes first, making it a target for prevention, not just a correlate.
|
||||
|
||||
**Race-stratified:** 47% of participants were Black, the population disproportionately affected by food insecurity and CVD. Results held after adjustment for socioeconomic factors, suggesting food insecurity is an independent mechanism beyond its correlation with poverty.
|
||||
|
||||
**Clinical implication:** Authors suggest food insecurity should be included in clinical CVD risk assessment tools. "If we address food insecurity early, we may be able to reduce the burden of heart disease later."
|
||||

||||
Published: JAMA Cardiology 10(5):456-462, May 2025 (released online March 2025).
|
||||
|
||||
## Agent Notes
|
||||
|
||||
**Why this matters:** Establishes temporality in the food insecurity → CVD causal chain. This is the prospective evidence that had been missing — not just "food insecure people have more CVD" but "food insecurity in young adulthood predicts CVD 20 years later." This is the upstream mechanism confirmation for the entire food-environment thread running since Session 15.
|
||||
|
||||
**What surprised me:** The 41% magnitude and the survival of the association after adjustment for socioeconomic factors. It's not just that poor people get CVD — food insecurity has an independent effect beyond income and education. This suggests the mechanism is specifically through nutrition pathways (the UPF-inflammation-hypertension chain) rather than only through general deprivation.
|
||||
|
||||
**What I expected but didn't find:** Race-stratified effect sizes (did the 41% figure hold equally for Black vs. white participants?). The study design included both, but the summary evidence doesn't separate the effect by race.
|
||||
|
||||
**KB connections:**
|
||||
- [[Americas declining life expectancy is driven by deaths of despair concentrated in populations and regions most damaged by economic restructuring since the 1980s]] — food insecurity as co-mechanism
|
||||
- [[Big Food companies engineer addictive products by hacking evolutionary reward pathways creating a noncommunicable disease epidemic]] — UPF as the specific food insecurity mechanism
|
||||
- [[medical care explains only 10-20 percent of health outcomes because behavioral social and genetic factors dominate]] — food insecurity here is a SDOH, not a medical factor
|
||||
- [[SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent]] — clinical integration gap
|
||||
- From Session 16: UPF → inflammation → hypertension (AHA REGARDS cohort) + five SDOH factors for hypertension non-control
|
||||
|
||||
**Extraction hints:**
|
||||
- New claim: "Food insecurity independently predicts 41% higher incident CVD risk in midlife after adjustment for socioeconomic factors, establishing temporality for the food environment → cardiovascular disease pathway"
|
||||
- This is **different from existing KB claims** — the CARDIA study is prospective, establishing causation direction, not just correlation
|
||||
- Confidence: proven (large prospective cohort, 20-year follow-up, adjusted for confounders)
|
||||
- Connect to the SDOH-hypertension thread as upstream mechanism

||||

## Curator Notes (structured handoff for extractor)
|
||||
|
||||
PRIMARY CONNECTION: [[Americas declining life expectancy is driven by deaths of despair concentrated in populations and regions most damaged by economic restructuring since the 1980s]]
|
||||
|
||||
WHY ARCHIVED: First prospective evidence establishing food insecurity as causal precursor to CVD (not just correlation), directly strengthening the structural SDOH mechanism chain built in Sessions 15-16.
|
||||
|
||||
EXTRACTION HINT: Extract as standalone claim: "Food insecurity in young adulthood independently predicts 41% higher CVD incidence in midlife, establishing temporality for the SDOH → cardiovascular disease pathway." Keep scope narrow — prospective in a specific cohort, not a systematic claim about all SDOH. Note the 47% Black composition and adjusted analysis.
