Abstract

Background: Development of clinical risk factors linked to metabolic syndrome (MetS) in adolescence is associated with higher incidence of atherosclerotic cardiovascular events in adulthood. Given the increasing burden of obesity and MetS in African-American (AA) youth, there is a need to establish the relation of MetS with modifiable risk factors such as diet quality, because these data may enhance preventative and treatment approaches. Objectives: The purpose of this study was to assess diet quality, measured by the Alternative Healthy Eating Index 2010 (AHEI-2010) and the Dietary Approaches to Stop Hypertension (DASH) pattern score, in AA adolescents and youth (aged 12-21 y) from the NHANES, and to investigate the association of diet quality with MetS and its components. Methods: This study is a cross-sectional analysis of NHANES data from the 2005-2016 cycles (n = 2459). Survey-weighted logistic regression models were used to assess the association of diet quality with the prevalence of MetS and individual cardiometabolic components [overweight/obesity, hypertensive blood pressure (BP), impaired fasting glucose, low HDL cholesterol, hypertriglyceridemia]. Results: The mean ± SD AHEI-2010 score was 38.9 ± 9.7 and DASH pattern score was 21.8 ± 4.4, which is equivalent to 35% adherence to recommendations to achieve an optimal diet quality and 45% adherence to the DASH-style dietary pattern, respectively. Compared with those within the lowest quartile of DASH pattern score, individuals in the fourth quartile group had 0.63 (95% CI: 0.41, 0.97) times the odds of having hypertensive BP. Among individuals with complete clinical measures (n = 1007), individuals within the highest-quartile AHEI-2010 group had 0.25 (95% CI: 0.06, 0.99) times the odds of having MetS compared with those within the lowest quartile. Conclusions: Diet quality in US AA youth is low. Higher DASH pattern scores were associated with lower odds of hypertensive BP and higher AHEI-2010 scores were associated with lower odds of MetS.
