- Abstract
Background: Higher scores for the American Heart Association Life's Essential 8 (LE8) metrics, blood pressure, cholesterol, glucose, body mass index, physical activity, smoking, sleep, and diet, are associated with lower risk of chronic disease. Socioeconomic status (SES; employment, insurance, education, and income) is associated with LE8 scores, but there is limited understanding of potential differences by sex. This analysis quantifies the association of SES with LE8 for each sex, within Hispanic Americans, non-Hispanic Asian Americans, non-Hispanic Black Americans, and non-Hispanic White Americans., Methods and Results: Using cross-sectional data from the National Health and Nutrition Examination Survey, years 2011 to 2018, LE8 scores were calculated (range, 0-100). Age-adjusted linear regression quantified the association of SES with LE8 score. The interaction of sex with SES in the association with LE8 score was assessed in each racial and ethnic group. The US population representatively weighted sample (13 529 observations) was aged ≥20 years (median, 48 years). The association of education and income with LE8 scores was higher in women compared with men for non-Hispanic Black Americans and non-Hispanic White Americans ( P for all interactions <0.05). Among non-Hispanic Asian Americans and Hispanic Americans, the association of SES with LE8 was not different between men and women, and women had greater LE8 scores than men at all SES levels (eg, high school or less, some college, and college degree or more)., Conclusions: The factors that explain the sex differences among non-Hispanic Black Americans and non-Hispanic White Americans, but not non-Hispanic Asian Americans and Hispanic Americans, are critical areas for further research to advance cardiovascular health equity.
