Introduction: The COVID-19 pandemic has raised global income inequality. This study analyzes the association between personal income level and cardiovascular health matrix (CHM) utilizing AHA life’s essential 8 in Koreans. Methods: This study used the 2019-2021 Korean National Health and Nutrition Examination Survey. Those who have missing data for assessing Life’s essential 8 were excluded. A final total of 12,923 participants were enrolled in this study. We used Life's essential 8 CHM Metrix as exposure, defined by the AHA. Diet redefined them appropriately for the Korean population. The unweighted average of each CHM score was calculated, and the cardiovascular health assessment groups were categorized as "high (80-100)," "medium (50-79)," and "low (0-49)" and then subjected to logistic regression analysis. The results were adjusted for sex, age, education, drinking status, perceived stress, and family history of physician chronic disease diagnosis. Results: Score of diet, physical activity, nicotine exposure, sleep health, body mass index, blood glucose, and blood pressure were positively associated with personal income level (Figure 1). Compared to the middle CVH group and lower income level group, higher income levels were associated with being in the high CVH group before (OR 1.6, 95%CI 1.4-1.8) and after adjusted (OR 1.5, 95%CI 1.2-1.7) confounders. Conclusions: This study showed that personal income was positively associated with the total life’s essential 8 CVH score and individual factors of life’s essential 8. Our results imply that socioeconomic factors, specifically personal income levels, exert influence even within what is considered an individual's realm (diet, physical activity, nicotine exposure, sleep health, body mass index, blood glucose, blood pressure) of control.
