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.

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.
