Key result
Obesity was associated with increased cardiovascular disease mortality in White individuals (ARR 1.18; 95% CI 1.07-1.29) but not in Black individuals (ARR 0.91; 95% CI 0.77-1.05).
Why the study?
Does obesity differentially affect cardiovascular disease mortality risk in Black versus White individuals?
Meta-Analysis
Yes
Does obesity differentially affect cardiovascular disease mortality risk in Black versus White individuals?
Effect estimate: ARR 1.18 (White) vs 0.91 (Black) (95% CI 1.07-1.29 (White) vs 0.77-1.05 (Black))
Obesity appears to be a stronger independent risk factor for cardiovascular and coronary heart disease mortality in White individuals compared to Black individuals.

Suggests race-specific obesity-CVD mortality risks; leaves open whether this informs targeted prevention or requires prospective confirmation.
Abell et al. (2007) conducted a meta-analysis in Cardiovascular disease mortality. Obesity vs. Non-obese was evaluated on Cardiovascular disease mortality (ARR 1.18 (White) vs 0.91 (Black), 95% CI 1.07-1.29 (White) vs 0.77-1.05 (Black)). Obesity was associated with increased cardiovascular disease mortality in White individuals (ARR 1.18; 95% CI 1.07-1.29) but not in Black individuals (ARR 0.91; 95% CI 0.77-1.05).
