Distribution of waist-to-hip ratio, other indices of body fat distribution and obesity and associations with HDL cholesterol in children and young adults aged 4-19 years: The Third National Health and Nutrition Examination Survey.
BACKGROUND
Little data has been published on the association of indices of body fat distribution and HDL cholesterol (HDL), a risk factor for cardiovascular morbidity, in representative samples of total populations of children and adolescents including blacks and Hispanics.


OBJECTIVE
To describe the distribution of waist-to-hip ratio (WHR) in US children and adolescents and to assess the association with HDL.


METHODS
Cross-sectional survey of a large national sample, the Third National Health and Nutrition Examination Survey.


METHODS
People aged 4-19 y.


METHODS
Body circumferences, skinfold thickness, body mass index (BMI), and serum total and HDL cholesterol concentrations.


RESULTS
Mean WHR varied consistently with age, gender, and ethnic group. Levels were highest in Mexican Americans. WHR showed significant negative associations with HDL cholesterol concentration and positive associations with the ratio of total serum cholesterol to HDL in pre- and postpubertal girls independent of age and BMI. However, associations were often not as strong as those with BMI. Other indices of body fat distribution were not superior to WHR.


CONCLUSIONS
Further research is needed on the association of WHR, other indices of body fat distribution and HDL measured in childhood with subsequent risk of atherosclerosis.
