Diet quality is inversely related to cardiovascular risk factors in adults.
The goal of the study was to determine if there was an association between diet quality and cardiovascular risk factors (CVRF) in adults. NHANES 2001-2008 data were used to compare diet quality, as determined by using 2005 Healthy Eating Index (HEI-2005) scores, and CVRF in adults aged ≥19 y (n = 18,988; 51% men, 50% white, 21% African American, 25% Hispanic American, 4% other). HEI-2005 scores were calculated by using one 24-h dietary recall collected from the participants. Weight and adiposity, blood pressure, and CVRF were measured. Regression analyses were conducted to assess the linear relationship of CVRF and HEI-2005 scores by using appropriate covariates accounting for sample weights and the complex sample design of NHANES. OR were calculated for HEI quartiles and CVRF. BMI (P < 0.0001), waist circumference (WC) (P < 0.0001), diastolic blood pressure (P = 0.0002), C-reactive protein (P = 0.0016), total cholesterol (P = 0.0006), LDL cholesterol (P = 0.0039), and metabolic syndrome (P = 0.0035) were inversely associated with HEI-2005. HDL cholesterol significantly (P = 0.0048) increased across HEI-2005 quartiles. Compared with the lowest HEI-2005 quartile, individuals with the highest diet quality (HEI-2005 quartile 4) were less likely to be overweight or obese (34%) or have elevated WC (35%), elevated blood pressure (26%), metabolic syndrome (35%), and decreased HDL-cholesterol concentrations (21%). Data suggest that diet quality is inversely associated with several CVRF.
