Healthy Eating Index and Metabolically Healthy Obesity in U.S. Adolescents and Adults.
Sommaire de l'article
To determine whether dietary quality differs between metabolically-healthy-obesity (MHO) and metabolically-abnormal-obesity (MAO) in a nationally representative sample.
National Health and Nutrition Examination Survey (NHANES) data (2007-2008; 2009-2010) were used to identify obese adolescents (≥95th body mass index (BMI) %tile) and adults (≥30kg/m²). MHO was defined as <2 abnormal cardiometabolic risk factors (elevated blood pressure, triglycerides, glucose, low high density lipoprotein cholesterol (HDL-C); or on medications). Healthy Eating Index 2005 (HEI-2005) scores were calculated from 24-hour recall data. General linear regression models determined whether HEI-2005 scores differed between MHO and MAO after controlling for age, race, gender, NHANES wave, BMI, physical activity and health status by age group (12-18; 19-44; 45-85years).
Compared with MAO, MHO adolescents (n=133) had higher total HEI-2005 score, higher milk scores, and higher scores from calories from solid fats, alcohol beverages and added sugars. MHO women 19-44 years (n=240) had higher total HEI-2005, higher whole fruit, higher whole grain and higher meat and bean scores compared with MAO. No significant differences were observed between MHO and MAO for HEI-2005 total scores in men 19-44 years, or adults 45-85 years.
MHO adolescents and women 19-44 years have better dietary compliance to the U.S. guidelines when compared with MAO, suggesting potential intervention targets to improve cardiometabolic risk within obesity.
