Key result
High neighborhood social vulnerability is linked to ~5-point lower midlife cardiovascular health scores.
Why the study?
The association of neighborhood social vulnerability with Life's Essential 8, and whether changes in vulnerability track with cardiovascular health changes during midlife, remained unclear.
Does higher neighborhood social vulnerability reduce Life's Essential 8 cardiovascular health scores in midlife adults?
Cohort (n=3,168)
Yes
Does higher neighborhood social vulnerability reduce Life's Essential 8 cardiovascular health scores in midlife adults?
Mean Difference: -5.34 (95% CI -6.9–-3.78)
Higher neighborhood social vulnerability is independently associated with lower cardiovascular health at midlife, driven primarily by lower scores in physical activity and nicotine exposure.
Neighborhood social vulnerability was associated with lower midlife LE8 scores; leaves open whether targeting social determinants improves cardiovascular health.
Background: Neighborhood social vulnerability may shape cardiovascular health (CVH), but its association with Life's Essential 8 (LE8), and whether changes in vulnerability track with changes in CVH during midlife, are unclear. We examined cross-sectional and longitudinal associations of the Social Vulnerability Index (SVI) with LE8 and assessed differences by SVI domain, LE8 component, race, and sex. Methods: We analyzed CARDIA participants at Year 15 (Y15; 2000-2001; n = 3,168; mean age 40 years) and Year 30 (Y30; 2015-2016; n = 2,267; mean age 55 years). Residential addresses were geocoded and linked to 2000 and 2016 SVI. Participants were stratified by SVI quartiles. CVH scores were calculated from LE8 metrics (range 0-100; higher is better CVH), excluding sleep. Using multivariable linear regression adjusted for age, sex, race, and educational attainment, we estimated LE8 differences across SVI quartiles and associations of 15-year SVI change/residential mobility with change in LE8. Cox models estimated incident CVD associations. Results: Higher SVI was associated with lower LE8 at both exams. Adjusted Q4 vs Q1 differences in overall LE8 were -5.34 points (95% CI, -6.90 to -3.78) at Y15 and -4.60 points (95% CI, -6.51 to -2.69) at Y30. Among the four SVI domains, SES and household characteristics drove most of the disparity in LE8 scores (Y30 Q4 vs. Q1: SES Δ = -6.98; household Δ = -6.56 points). Component-level differences across quartiles of SVI were largest for nicotine exposure at Y15 (-13.09 points) and physical activity at Y30 (-13.09 points). Changes in SVI and residential mobility were not significantly associated with change in LE8. Conclusion: Higher social vulnerability was associated with significantly lower CVH. Socioeconomic and household factors, along with behavioral gaps in nicotine exposure and physical activity, may be key targets for community-level interventions to improve cardiovascular health equity.

Walker et al. (2026) conducted a cohort in General population without prior cardiovascular disease (n=3,168). Higher neighborhood social vulnerability (Social Vulnerability Index Q4) vs. Lowest quartile of neighborhood social vulnerability (SVI Q1) was evaluated on Difference in overall Life's Essential 8 (LE8) score (Mean difference -5.34 points, 95% CI -6.90 to -3.78). Higher neighborhood social vulnerability was associated with significantly lower Life's Essential 8 cardiovascular health scores at midlife (mean difference -5.34 points for the highest versus lowest quartile).
