HDL2 Associated With Better Heart Health

Byron's Comments:

Boosting HDL2 levels is a goal for cardiovascular health.

Study Title:

High-Density Lipoprotein (HDL), HDL2, and HDL3 Cholesterol Concentrations Determined in Serum of Newborns, Infants, Children, Adolescents, and Adults by Use of a Micromethod forCombined Precipitation Ultracentrifugation.

Study Abstract:

Cholesterol (C) concentrations in the two major subtractions of high-density lipoproteins (HDL2-C and HDL3-C) in sera from both sexes, ages ranging from newborns to adults, were measured by use of a micromethod for combined precipitation-ultracentrifugation. Sera were obtained from 91 boys, 68 girls, 15 healthy men, and 14 women. The HDL2-C concentration was higher in women than in men; the HDL3-C concentration was similar in these two groups. This sexrelated
difference, generally seen in adults, was found to begin at ages 11-15 y. The value of HDL2-C in females increased with age in a stepwise manner, whereas that in
males increased up to ages 6-10 y but tended to decline thereafter. The HDL3-C concentration was higher in the adults than in the children. This micromethod for separating operationally defined HDL subtractions is of value for lipoprotein research in children.
