title: Hyperlipidemia in the Pacific Northwest Bell Telephone Company Health Survey. Part 1. Lipoprotein cholesterol and triglyceride concentrations.
abstract: Lipoprotein triglyceride and cholesterol concentrations and characteristics are described in normolipidemic and in three categories of hyperlipidemic subjects participating in the Pacific Northwest Bell Telephone Company Health Survey. For this study, 350 white participants 20 to 59 years of age with cholesterol or triglyceride values exceeding the age, sex, and hormone-use specific, population-based 90th percentile values were defined as having hypercholesterolemia, hypertriglyceridemia, or combined hyperlipidemia; 722 participants were classified as normolipidemic. In hypercholesterolemia, very low density lipoprotein cholesterol and triglyceride and high density lipoprotein cholesterol concentrations were higher than in normolipidemia. In hypertriglyceridemia, high density lipoprotein cholesterol was significantly lower in men and women not using sex hormones and low density lipoprotein triglyceride was significantly higher in men and women using hormones compared to normolipidemia. In combined hyperlipidemia, high density lipoprotein cholesterol concentrations were lower than in normolipidemia, but higher than in pure hypertriglyceridemia. The presence of beta migrating very low density lipoprotein and chylomicrons was seen primarily in hypertriglyceridemic or combined hyperlipidemic men. Sinking prebeta lipoprotein was equally common (20%) among all normolipidemic and hypercholesterolemic subjects, but was less common (5% to 10%) in hypertriglyceridemic and combined hyperlipidemic men and female hormone users. Quantitative and qualitative lipoprotein abnormalities associated with hyperlipidemia were found to vary by gender and by sex hormone use in women and were often, but not always, more marked in men.
