American Heart Association Life's Essential 8 and Heart Failure in Black Individuals: An Analysis of the National Health and Nutrition Examination Survey.

Black individuals were diagnosed with heart failure at a younger age than White individuals.

• Mean age at HF diagnosis was 54 years in Black individuals vs 65 years in White individuals (P<0.001).
• Analysis used NHANES data from 1999 to 2020, with 107,622 individuals categorized by self-reported race.
• HF diagnosis was based on self-report.

Higher body mass index was associated with increased odds of HF among Black individuals.

• OR 1.041 (95% CI, 1.027-1.055), P=0.02.
• Estimated using multivariable logistic regression models in Black individuals.

Hypertension was strongly associated with increased odds of HF among Black individuals.

• OR 3.175 (95% CI, 2.14-4.69), P<0.0001.
• Hypertension was based on self-reported diagnosis.

Hyperlipidemia was associated with increased odds of HF among Black individuals.

• OR 1.36 (95% CI, 1.04-1.76), P=0.02.
• Hyperlipidemia was based on self-reported diagnosis.

Diabetes was associated with increased odds of HF among Black individuals.

• OR 2.07 (95% CI, 1.60-2.67), P≤0.0001.
• Diabetes was based on self-reported diagnosis.

Physical activity was associated with lower odds of HF among Black individuals.

• OR 0.564 (95% CI, 0.38-0.836), P=0.004.
• Physical activity was self-reported and used as one of the Life's Essential 8 components.

The study evaluated a subset of Life's Essential 8 components using self-reported NHANES variables in a cross-sectional design.

• Life's Essential 8 was represented by self-reported sleep duration, physical activity, smoking status, and dietary habits.
• Self-reported diagnoses of diabetes, hyperlipidemia, hypertension, and HF were also included.
• Cross-sectional design with multivariable logistic regression estimating ORs and 95% CIs.
