| Summary: | This study examines the relationship between diet quality and total body and regional
body fat. Adolescent obesity is becoming a major public challenge in the United States. Obesity
is a multifactorial disease that, if developed in early years of life, can track into later years.
Persistent obesity is associated with an increased risk of developing type-2 diabetes, heart
disease and some cancers. Diet quality and patterns seen in adolescence are important to
understand since they can promote fat gain and development of obesity. Anthropometric
measures were obtained using standard protocols and body composition measures were obtained
using dual energy x-ray absorptiometry (DXA). The validated Youth Healthy Eating Index
(YHEI) was used to assess diet quality via 14 different components. Multiple linear regressions
suggested that the components of the YHEI of fried foods, margarine and butter use, snack foods
and dairy were all significantly and directly related to the body composition measures of total
percent body fat, android percent fat and BMI. Total YHEI score was significantly and inversely
related to the body composition measures. In conclusion, this study suggests that diet quality is a
good predictor of body composition, including regional and total adiposity. |
