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

ABSTRACT:

Background

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.

Methods

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).

Results

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.

Conclusions

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.

Impact

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:ImportanceNumerous efforts have been made to include diverse populations in genetic studies, but American Indian populations are still severely underrepresented. Polygenic scores derived from genetic data have been proposed in clinical care, but how polygenic scores perform in American Indian individuals and whether they can predict disease risk in this population remains unknown.ObjectiveTo study the performance of polygenic scores for cardiometabolic risk factors of lipid traits and C-reactive protein in American Indian adults and to determine whether such scores are helpful in clinical prediction for cardiometabolic diseases.Design, setting, and participantsThe Strong Heart Study (SHS) is a large American Indian cohort recruited from 1989 to 1991, with ongoing follow-up (phase VII). In this genetic association study, data from SHS American Indian participants were used in addition to data from 2 large-scale, external, ancestry-mismatched genome-wide association studies (GWASs; 450 865 individuals from a European GWAS and 33 096 individuals from a multi-ancestry GWAS) and 1 small-scale internal ancestry-matched American Indian GWAS (2000 individuals). Analyses were conducted from February 2023 to August 2024.ExposureGenetic risk score for cardiometabolic disease risk factors from 6 traits including 5 lipids (apolipoprotein A, apolipoprotein B, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides), and an inflammatory biomarker (C-reactive protein [CRP]).Main outcomes and measuresData from SHS participants and the 2 GWASs were used to construct 8 polygenic scores. The association of polygenic scores with cardiometabolic disease was assessed using 2-sided z tests and 1-sided likelihood ratio tests.ResultsIn the 3157 SHS participants (mean [SD] age, 56.44 [8.12] years; 1845 female [58.4%]), a large European-based polygenic score had the most robust performance (mean [SD] R2 = 5.0% [1.7%]), but adding a small-scale ancestry-matched GWAS using American Indian data helped improve polygenic score prediction for 5 of 6 traits (all but CRP; mean [SD] R2, 7.6% [3.2%]). Lipid polygenic scores developed in American Indian individuals improved prediction of diabetes compared with baseline clinical risk factors (area under the curve for absolute improvement, 0.86%; 95% CI, 0.78%-0.93%; likelihood ratio test P = 3.8 × 10-3).Conclusions and relevanceIn this genetic association study of lipids and CRP among American Indian individuals, polygenic scores of lipid traits were found to improve prediction of diabetes when added to clinical risk factors, although the magnitude of improvement was small. The transferability of polygenic scores derived from other populations is still a concern, with implications for the advancement of precision medicine and the potential of perpetuating health disparities, particularly in this underrepresented population.
