Abstract MP78: Race/Ethnic Disparities in Children’s Cardiovascular Health: The Role of Social Disadvantage in Early Life

Abstract

Introduction: The loss of cardiovascular health (CVH) begins early in life and disproportionately affects racial/ethnic minorities, particularly children in single parent households, and households with lower education, family income and food insecurity. However, the contribution of these social determinants to CVH disparities in childhood are poorly understood. Hypothesis: We hypothesized that racial/ethnic differences in CVH among US children are explained by social disadvantages. Methods: Data from the 2013-2018 National Health and Nutrition Examination Survey for children aged 2-18 (N=4,792) were used. CVH was measured using the AHA Life’s Essential 8 scores that combine nicotine exposure, diet, physical activity, sleep, body mass index, and blood pressure, lipids, and glucose. Oaxaca-Blinder decomposition methods were used to quantify the contributions of parental education, marital status and household income to poverty ratio, and food security to differences in CVH by race and sex. Results: Mean CVH score was highest among non-Hispanic White (mean [SE] = 73.7 [0.5]) than non-Hispanic Black (71.3 [0.6]) and Hispanic children (71.0 [0.4]). There was no significant difference among Black-White boys (mean differences [MD] = -1.52; 95% CI: -3.25, 0.21). Black girls had significantly lower CVH than White girls (MD= -2.66; 95% CI: -4.40, -0.91). Differences in parental college education accounted for 46% of the differences in CVH scores (MD = -1.21; 95% CI: -1.89, -0.54). Among Hispanic children, both boys (MD = -2.47; 95% CI: -4.22, -0.73) and girls (MD = -3.09; 95% CI: -4.60, -1.58) had significantly lower CVH scores than White boys and girls, respectively. Differences in parental education explained 66% of the difference in CVH among White-Hispanic boys and girls (MD= -0.66; 95%CI-1.11, -0.20; and MD= -0.66; 95%CI-1.20, -0.13). Discussion: Differences in parental college education largely explained lower levels of CVH among US Black and Hispanic children, a predictor of future cardiovascular disease.
