title: Altered plasma lipid and lipoprotein levels associated with oral contraceptive and oestrogen use. Report from the Medications Working Group of the Lipid Research Clinics Program.
abstract: In a study of women attending ten North American Lipid Research Clinics plasma total cholesterol, triglyceride, low density (L.D.L.), very low density (V.L.D.L.), and high density (H.D.L.) lipoprotein levels in those taking oral contraceptives (O.C.) and in those taking oestrogens for menopausal symptoms were compared with those in women not taking gonadal hormones, after adjustment for age, educational attainment, and body-mass index, O.C. and oestrogen users were leaner than non-users. Compared with controls, O.C. users showed increased cholesterol, triglyceride, and L.D.L.-cholesterol and V.L.D.L.-cholesterol levels, but H.D.L.-cholesterol levels were similar. Cholesterol, triglyceride, and H.D.L.-cholesterol and V.L.D.L.-cholesterol levels were positively associated with the quantity of the oestrogen component of the O.C. preparations. Compared with non-users, menopausal oestrogen users had slightly lower cholesterol and triglyceride levels, significant decreases in L.D.L.-cholesterol and V.L.D.L.-cholesterol, and a significant increase in H.D.L.-cholesterol.
