The critical finding is specificity: SNAP showed zero effect on medication adherence in food-secure populations. This dose-response pattern validates a specific mechanism—food insecurity creates a budget constraint that forces households to choose between food and medication purchases. SNAP relieves this trade-off by providing food purchasing power, freeing household income for medications. This is distinct from the dietary pathway studied in Food is Medicine interventions. The effect operates at scale through existing SNAP infrastructure (serving 42 million Americans) without requiring new clinical programs. While this study measures adherence rather than blood pressure directly, medication nonadherence is the primary driver of treatment-resistant hypertension, making the clinical pathway to BP control well-established even though not directly measured here. + +--- + +Relevant Notes: +- [[five-adverse-sdoh-independently-predict-hypertension-risk-food-insecurity-unemployment-poverty-low-education-inadequate-insurance]] +- [[food-insecurity-independently-predicts-41-percent-higher-cvd-incidence-establishing-temporality-for-sdoh-cardiovascular-pathway]] +- [[SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent and no operational infrastructure connects screening to action]] + +Topics: +- [[_map]] diff --git a/inbox/queue/.prior-art/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.txt b/inbox/queue/.prior-art/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.txt new file mode 100644 index 000000000..e335dca8f --- /dev/null +++ b/inbox/queue/.prior-art/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.txt @@ -0,0 +1,4 @@ +## Prior Art (automated pre-screening) + +- [food-insecurity-independently-predicts-41-percent-higher-cvd-incidence-establishing-temporality-for-sdoh-cardiovascular-pathway](domains/health/food-insecurity-independently-predicts-41-percent-higher-cvd-incidence-establishing-temporality-for-sdoh-cardiovascular-pathway.md) — similarity: 0.57 — matched query: "food insecurity hypertension" +- [five-adverse-sdoh-independently-predict-hypertension-risk-food-insecurity-unemployment-poverty-low-education-inadequate-insurance](domains/health/five-adverse-sdoh-independently-predict-hypertension-risk-food-insecurity-unemployment-poverty-low-education-inadequate-insurance.md) — similarity: 0.56 — matched query: "food insecurity hypertension" diff --git a/inbox/queue/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.md b/inbox/queue/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.md index e6764ed92..cc8255edf 100644 --- a/inbox/queue/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.md +++ b/inbox/queue/2024-02-23-jama-network-open-snap-antihypertensive-adherence-food-insecure.md @@ -7,9 +7,15 @@ date: 2024-02-23 domain: health secondary_domains: [] format: journal article -status: unprocessed +status: processed priority: high tags: [SNAP, hypertension, medication-adherence, food-insecurity, SDOH, antihypertensive] +processed_by: vida +processed_date: 2026-04-01 +claims_extracted: ["snap-reduces-antihypertensive-nonadherence-13-6-pp-in-food-insecure-patients-through-food-medication-trade-off-relief.md"] +enrichments_applied: ["five-adverse-sdoh-independently-predict-hypertension-risk-food-insecurity-unemployment-poverty-low-education-inadequate-insurance.md", "food-as-medicine-interventions-produce-clinically-significant-improvements-during-active-delivery-but-benefits-fully-revert-when-structural-food-environment-support-is-removed.md"] +extraction_model: "anthropic/claude-sonnet-4.5" +extraction_notes: "pre-screen: 2 prior art claims from 5 themes" --- ## Content @@ -53,3 +59,11 @@ PRIMARY CONNECTION: [[SDOH interventions show strong ROI but adoption stalls bec WHY ARCHIVED: Provides specific mechanism evidence for SNAP improving hypertension outcomes — via medication adherence pathway, not dietary change.
