title: Effects of age and cigarette smoking on serum concentrations of lipids and apolipoproteins in a male military population.
abstract: The effects of age and cigarette smoking on lipids and apolipoproteins were studied in men, 20-65 years old, randomly selected from a military population in the Madrid area, Spain. Subjects were classified as non-smokers, medium smokers (10-20 cigarettes/day) and heavy smokers (more than 20 cigarettes/day). Smoking prevalence was 58%. Serum apolipoprotein A-I and HDL-cholesterol (HDL-C) were not age-dependent, while total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C) and the TC/HDL-C ratio increased with age. None of the variables studied was age-dependent over 30 years. The effects of smoking on TC, TG, LDL-C, HDL-C, TC/HDL-C ratio, apolipoprotein A-I, apolipoprotein B, and apo A-I/apo B ratio in the 20-29-year-old group appeared to be prominent in heavy smokers (P values less than 0.001, less than 0.05, less than 0.01, less than 0.05, less than 0.001, less than 0.05, less than 0.01 and less than 0.05, respectively) but not in medium smokers, in which only TG increased significantly (P less than 0.001). Few differences were noted between non-smokers and smokers over 30 although the TC/HDL-C ratio did increase in heavy smokers (P less than 0.05).
