Diet quality scores associated with improved cardiometabolic measures among African American adolescents.

ABSTRACT: The Reversing the Negative cardiovascular Effects on Weight (ReNEW) Clinic is a prospective cohort study in children and adolescents (≤21 years) at the Johns Hopkins Children's Center. Cross-sectional analysis between diet quality using the Alternative Healthy Eating Index (AHEI-2010), pro-inflammatory potential using the Children's Dietary Inflammatory Index (C-DII), and cardiometabolic outcomes. AHEI-2010 and C-DII scores were assessed by median intake determined from the sample distribution and associated with cardiometabolic measures using linear regression models. Changes in measures were evaluated in a sub-sample of participants invited to attend follow-up visits due to the presence of hypertensive blood pressure (n = 33). Participants (n = 90) reported an average energy intake of 1790 kcal/day (SD ± 734), AHEI-2010 score of 55.04 (SD ± 9.86) (range: 0 to 110) and C-DII score of -0.12 (±0.86) (range -5 to 5). Participants with higher quality/anti-inflammatory diets trended towards more favorable cardiometabolic measures at baseline. Among the sub-sample (n = 33), there was a significant reduction in total energy (m = -302 kcal/day; p-value= 0.03) but no change in AHEI-2010 (p-value = 0.73) or C-DII score (p-value = 0.85) over follow-up. Despite stable diet quality scores, outpatient dietary and behavioral counseling may be an effective tool to reduce energy intake in youth with overweight/obesity and elevated blood pressure. Diet quality scores among obese, hypertensive, African American adolescents were low and reflect a pro-inflammatory diet. Reported intake was negligible for fruits, whole grains, nuts, and legumes, and well above the daily limit for sodium and saturated fat. Participants with high quality/anti-inflammatory diet quality scores trended toward improved cardiometabolic measures. Outpatient dietary counseling resulted in reduced total energy intake.

Project description:BackgroundDevelopment 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.ObjectivesThe 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.MethodsThis 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].ResultsThe 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.ConclusionsDiet 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.

Project description:BackgroundCardiovascular disease (CVD) is the leading cause of mortality among US adults. African Americans have higher burden of CVD morbidity and mortality compared to any other racial group. Identifying biomarkers for clinical risk prediction of CVD offers an opportunity for precision prevention and earlier intervention.ResultsUsing linear mixed models, we investigated the cross-sectional association between four measures of epigenetic age acceleration (intrinsic (IEAA), extrinsic (EEAA), PhenoAge (PhenoAA), and GrimAge (GrimAA)) and ten cardiometabolic markers of hypertension, insulin resistance, and dyslipidemia in 1,100 primarily hypertensive African Americans from sibships in the Genetic Epidemiology Network of Arteriopathy (GENOA). We then assessed the association between epigenetic age acceleration and time to self-reported incident CVD using frailty hazard models and investigated CVD risk prediction improvement compared to models with clinical risk scores (Framingham risk score (FRS) and the atherosclerotic cardiovascular disease (ASCVD) risk equation). After adjusting for sex and chronological age, increased epigenetic age acceleration was associated with higher systolic blood pressure (IEAA), higher pulse pressure (EEAA and GrimAA), higher fasting glucose (PhenoAA and GrimAA), higher fasting insulin (EEAA), lower low density cholesterol (GrimAA), and higher triglycerides (GrimAA). A five-year increase in GrimAA was associated with CVD incidence with a hazard ratio of 1.54 (95% CI 1.22-2.01) and remained significant after adjusting for CVD risk factors. The addition of GrimAA to risk score models improved model fit using likelihood ratio tests (P = 0.013 for FRS and P = 0.008 for ASCVD), but did not improve C statistics (P > 0.05). Net reclassification index (NRI) showed small but significant improvement in reassignment of risk categories with the addition of GrimAA to FRS (NRI: 0.055, 95% CI 0.040-0.071) and the ASCVD equation (NRI: 0.029, 95% CI 0.006-0.064).ConclusionsEpigenetic age acceleration measures are associated with traditional CVD risk factors in an African-American cohort with a high prevalence of hypertension. GrimAA was associated with CVD incidence and slightly improved prediction of CVD events over clinical risk scores.
