Abstract 14394: Overweight and Obesity Across the Lifespan Among White and Black Congenital Heart Disease Survivors
Introduction: Rates of obesity among adults with congenital heart disease (CHD) living in the U.S. have risen, contributing to increased morbidity and mortality. In the general population, obesity rates are higher among Black adults than Whites. However, research on health outcomes among ethnic minority survivors of CHD is lacking.
Methods: Medical chart abstraction from a both a pediatric and adult hospital identified 4852 individuals who received a diagnosis of structural CHD spanning childhood (ages 6-12; n = 1504), adolescence (ages 13-18; n = 1085), young adulthood (ages 19-39; n = 1387), and adulthood (ages ≥ 40; n = 876). The sample was 84.7% White, 9.3% Black, and 5.8% “Other” (i.e., Latino, Asian, biracial, and non-U.S. citizens). Disease severity was representative (36% simple; 50% moderate; 14% complex). BMI was calculated from the most recent hospital visit and was categorized as either normal or overweight/obese based on Center for Disease Control definitions. Underweight individuals were excluded from analyses. Observed and expected frequencies of overweight/obese were compared using chi-square tests.
Results: The following proportion of individuals with CHD was overweight/obese: 32.9% of children, 37.6% of adolescents, 59.1% of young adults, and 72.3% of adults. The frequency of overweight/obese among adolescents with CHD was higher than expected based on CDC state data for adolescents (27.4% overweight/obese; χ2 = 56.8 , p < 0.01). Rates of overweight/obese for adults with CHD 19+ years (62.2%) were similar to Ohio adults (65%). In comparing White and Black survivors, Black survivors had significantly higher rates of overweight/obese in adolescence (White = 37.1% vs. Black = 48.3%; χ2 = 63.8 , p < 0.01) and young adulthood (White = 57.7% vs. Black = 70.6%; χ2 = 22.1 , p < 0.01) with a trend in adulthood (White = 72.5% vs. Black = 83%; χ2 = 2.9 , p = 0.09).
Conclusion: Rates of overweight/obese among adolescent CHD survivors is higher than state data, which is alarming considering that precursors for atherosclerosis have been identified in children and adolescents with CHD. Furthermore, rates of obesity in both adolescence and young adulthood are higher among Black CHD survivors which may contribute to outcome disparities.
