[Plasma levels of apoproteins B and A in relation to blood cholesterol and triglycerides. Distribution according to age and sex and influence of various risk factors (author's transl)].

Plasma levels of apoproteins B and A, triglycerides, VLDL + LDL-cholesterol and HDL-cholesterol were simultaneously measured in an ambulatory population of 477 subjects (206 male and 271 female). VLDL + LDL-cholesterol and apo B values were similar in males and females and significantly increased with age. Conversely, HDL-cholesterol and apo A values were higher in females than in males and remained stable with age. HDL-cholesterol and apo A correlated inversely with triglycerides. Overweight, alcohol and smoking introduced significant changes in the parameters studied.
