Abstract B034: Association of Neighborhood-Level Food Environment with Prostate Cancer-Specific Mortality Among Men in Georgia

Q: What does this research mean for the field?

Men in high food swamp areas have a 14% higher risk of prostate cancer-specific mortality compared to non-Hispanic White men in low food swamp areas (aHR 1.18, p=0.04). Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

Key result

High food swamp exposure linked to ~18% higher prostate cancer mortality in men.

aHR 1.18
p=0.04

Why the study?

Food swamps have emerged as contextual determinants of cancer risk and survival, but their association with prostate cancer-specific mortality and racial disparities in Georgia was unknown.

Does greater food swamp exposure increase prostate cancer-specific mortality in men diagnosed with prostate cancer?

Key Points

To investigate the relationship between neighborhood-level food environment and prostate cancer-specific mortality (PCSM) in Georgia, particularly among different racial groups.
Conducted a retrospective analysis using Georgia Cancer Registry data (2000–2022).
Linked neighborhood food data with cancer registry data using Census tract-level codes.
Categorized food environments into low, moderate, and high exposure based on the Modified Retail Food Environment Index (RFEI).
Utilized Cox proportional hazards models to estimate associations between food exposure and PCSM, controlling for demographic and clinical factors.
70% of men lived in moderate/high food swamp tracts.
Each 1-unit increase in food swamp score was associated with a 1% higher risk of PCSM after age adjustment.
Moderate and high FS tracts showed a 14% and 18% increased risk of PCSM in non-Hispanic Black men, respectively.
No significant difference in risk among non-Hispanic White men in high FS areas.

Structured PICO

Does greater food swamp exposure increase prostate cancer-specific mortality in men diagnosed with prostate cancer?

Population

154,480 men diagnosed with prostate cancer in Georgia (2000–2022)

Intervention

Moderate or high food swamp (FS) exposure (high density of ultra-processed food outlets relative to grocery stores)

Comparator

Low food swamp exposure

Outcome

Prostate cancer-specific mortality (PCSM)hard clinical

Neighborhood food environments, specifically food swamps, may contribute to racial disparities in prostate cancer outcomes, with non-Hispanic Black men in moderate or high food swamp areas facing higher mortality risk.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Food swamp exposure may worsen prostate cancer mortality disparities; leaves open whether neighborhood interventions improve outcomes.
