Background The American Heart Association's Life's Essential 8 (LE8) are 8 risk factors for cardiovascular disease, with poor attainment across all racial, ethnic, and socioeconomic groups. Attainment is lowest among Americans of low socioeconomic status (SES). Evidence suggests the association of SES with LE8 may vary by race and ethnicity. Methods and Results The association of 4 SES categories (education, income‐to‐poverty line ratio, employment, insurance) with LE8 was computed in age‐adjusted linear regression models, with an interaction term for race and ethnicity, using National Health and Nutrition Examination Survey data, years 2011 to 2018. The sample (n=13 529) had a median age of 48 years (51% female) with weighting to be representative of the US population. The magnitude of positive association of college education (relative to ≤high school) with LE8 was greater among non‐Hispanic White Americans (NHWA) compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA had a greater magnitude of positive association of income‐to‐poverty line ratio with LE8, compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA with Medicaid compared with private insurance had a greater magnitude of negative association with LE8 compared with non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.01). NHWA unemployed due to disability or health condition (compared with employed) had a greater magnitude of negative association with LE8 than non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.05). Conclusions The magnitude of association of SES with LE8 is greatest among NHWA. More research is needed on SES's role in LE8 attainment in minority group populations.
