## Content

Published 2024 in *Hypertension* (American Heart Association journal). Full systematic review following PRISMA guidelines. PMC full text available: PMC12166636.

**Study design:** Systematic review of SDOH impacts on hypertension outcomes. From 10,608 unique records, **57 studies** met inclusion criteria.

**Core finding:** Multiple SDOH domains independently predict hypertension prevalence and poor BP control:

1. **Education** — higher educational attainment associated with lower hypertension prevalence and better control
2. **Health insurance** — insurance coverage independently associated with better BP control
3. **Income** — higher income → lower hypertension prevalence
4. **Neighborhood characteristics** — favorable neighborhood environment → lower hypertension
5. **Food insecurity** — directly associated with higher hypertension prevalence
6. **Housing instability** — associated with poor treatment adherence and outcomes
7. **Transportation** — a "common SDOH in economically challenged groups that can have a tremendous impact on treatment adherence and achieving positive health outcomes"

**Five adverse SDOH with significant hypertension risk associations** (from companion 2025 Frontiers study building on this evidence base):
- Unemployment
- Low poverty-income ratio
- Food insecurity
- Low education level
- Government or no insurance

**Key structural finding:** The review finds that multilevel collaboration and community-engaged practices are necessary to reduce hypertension disparities — siloed clinical or technology interventions are insufficient.

**CMS integration recommendation:** The review explicitly endorses CMS's HRSN (health-related social needs) screening tool as a hypertension care component — noting it should include housing instability, food insecurity, transportation, utility needs, and safety.

**Racial disparity dimension:** Black adults have significantly higher hypertension prevalence regardless of individual AND neighborhood poverty statuses compared to White adults — suggesting race operates through mechanisms beyond those captured by standard SDOH measures.

## Agent Notes

**Why this matters:** This is the definitive evidence base for the mechanism behind the 76.6% non-control rate identified in Session 15. The non-control problem is not primarily medication non-adherence in a behavioral sense — it is SDOH-mediated: food environment, housing instability, transportation, economic stress, insurance gaps all independently impair BP control. Medical care cannot overcome what the social environment continuously generates.

**What surprised me:** The racial disparity that persists even after controlling for income and neighborhood — suggesting structural racism operates through additional pathways not captured by standard SDOH measures. This is a gap in the KB's current hypertension framing.

**What I expected but didn't find:** Quantified effect sizes for each SDOH factor. The systematic review establishes direction but the 2025 Frontiers paper (different source) provides the five-factor list with statistical significance. Need the Frontiers paper for quantitative claims.

**KB connections:**
- `hypertension-related-cvd-mortality-doubled-2000-2023-despite-available-treatment-indicating-behavioral-sdoh-failure.md` — this is the "what" claim; this source provides the "why" (SDOH mechanism)
- `only-23-percent-of-treated-us-hypertensives-achieve-blood-pressure-control...` — same: this source explains the mechanism behind that claim
- `SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent...` — the infrastructure for screening exists on paper but isn't used
- `medical care explains only 10-20 percent of health outcomes...` — this review confirms the same at mechanism level for hypertension specifically
- `Big Food companies engineer addictive products by hacking evolutionary reward pathways...` — food insecurity + UPF access = the food environment SDOH mechanism for hypertension

**Extraction hints:**
- New claim: "Five adverse SDOH independently predict hypertension risk and poor BP control: food insecurity, unemployment, poverty-level income, low education, and government or no insurance — establishing the SDOH mechanism behind the US hypertension treatment failure"
- New claim: "Racial disparities in hypertension persist even after controlling for income and neighborhood poverty, indicating structural racism operates through additional mechanisms not captured by standard SDOH measures"

**Context:** AHA Hypertension journal is the flagship journal for hypertension research — this is the most authoritative single synthesis of SDOH-hypertension evidence available. 57 studies across methodologies provides convergent validity.

## Curator Notes

PRIMARY CONNECTION: `hypertension-related-cvd-mortality-doubled-2000-2023-despite-available-treatment-indicating-behavioral-sdoh-failure.md`

WHY ARCHIVED: Provides mechanistic grounding for the hypertension claims already in KB. The existing claims establish "what" (doubled mortality, low control rates); this source establishes "why" (five SDOH factors, multilevel mechanisms). Critical to extracting the SDOH-hypertension mechanism chain.

EXTRACTION HINT: Extract as a mechanism claim linking SDOH factors to hypertension non-control. The five-factor list is specific enough to be a standalone claim. The racial disparity finding is a separate claim candidate. Don't conflate the two — they're different causal mechanisms.
