A high level of non-HDL-C was defined as serum non-HDL-C concentration ≥145 mg/dL.
Number of subjects with a high level of non-HDL-C.
Normal weight defined as age- and sex-specific BMI of <85th percentile of CDC BMI-for-age growth charts (http://www.cdc.gov/growthcharts), overweight as age- and sex-specific BMI of 85th to <95th percentile of CDC BMI-for-age growth charts, and obesity as age- and sex-specific BMI of ≥95th percentile of the CDC BMI-for-age growth charts.
Poverty index is the ratio of a family’s income to the poverty threshold defined by the US Census Bureau (www.census.gov/hhes/www/poverty/data/threshld/index.html), appropriate to the family’s composition.
