title: The influence of the dietary habit on lipoprotein density in blood serum of men from Podlasie region.
abstract: In the years 1987-1998 we conducted examined a group of 556 men three times. The nutritional status was evaluated as well as total cholesterol, HDL- and LDL-cholesterol and triglycerides concentration in blood serum and it allowed to evaluate the influence of nutrition on lipid status. The relationships between diet composition and lipid levels in the whole period of 9 years were evaluated using multidimensional linear regression analysis. Among examined men, depending on the period of the study, values of serum total cholesterol (C <200 mg/dk) favourable from the standpoint of arteriosclerosis prevention were noted in only 36-39%, with LDL-cholesterol below 130 mg/dl in 35-48%, HDL-cholesterol over 35 mg/dl in 87-94% and triglyceride levels below 200 mg/dl in 81-83% of the studied men. Among 6 basic nutrients of the diet, only plant fat was significantly influencing the concentration of triglycerides in blood serum--an increase of its consumption caused the decrease of triglyceride level. It has been proven that increasing amount of alcohol in the diet led to the increase of HDL-cholesterol in blood serum. Blood serum lipids were significantly influenced by BMI. Increased body mass index significantly influenced the concentration of total cholesterol, LDL-cholesterol and triglycerides in blood serum. In examined men with the increase of body mass index the HDL-cholesterol concentration was decreasing. Summing it up-it has been shown that the diet of examined men directly and significantly influenced lipid concentration in blood serum, and it also had an indirect influence on lipid concentration, through body mass regulation, which significantly influenced its concentration.
