β: beta; <HS: less than high school, HS: high school, >HS: greater than high school.
Adjusted model: age (4 categories), marital status, smoking status, leisure-time physical activity, alcohol consumption, poor income, region of country, and self-reported general health status; 𝑃 values represent sex-specific slope differences between Blacks and Whites by education level from linear regression models; combined interaction term race, education and survey year.
