title: Lipids and lipoproteins in 13--18-year-old Venezuelan and American school children. Within- and cross-cultural comparisons.
abstract: Plasma lipids, lipoproteins, and anthropometric measurements were assessed in 996 Venezuelan school children (ages 13--18 years) (441 in private, 555 in public schools, Merida, Venezuela) with cross-cultural comparisons to 419 13--18-year-old American school children from suburban Cincinnati, Ohio. Although there were no systematic differences in plasma cholesterol and triglyceride between public and private Venezuelan school children, low density lipoprotein cholesterol (LDL-C) levels were higher and high density lipoprotein cholesterol (HDL-C) levels lower in public than private school children. Within Venezuelan schools, and between sex, female children had consistently higher total plasma cholesterol, marginally higher HDL-C, and appreciably higher LDL-C than males. There were no consistent cross-sectional changes in lipids and lipoproteins in Venezuelan school children with age. Within sex, cross-cultural comparisons with Cincinnati school children revealed 2 major, consistent differences; Venezuelan children had higher fasting plasma triglyceride and lower HDL-C levels, not attributable to systematic differences in Quetelet index, laboratory methodology, subject selection, or sampling technique. Total plasma cholesterol and HDL-C were similar for Venezuelan and Cincinnati school children. Maintenance of comparable LDL-C but lower HDL-C levels by Venezuelan children into adulthood might, speculatively, be associated with augmented risk for coronary heart disease.
