| Abstract: | We studied factors influencing concentrations of triglycerides in the blood of a presumably healthy population of about 9000 persons. Using multi-dimensional analysis, we show, in addition to various related to sex and age, the relation between triglycerides and uric acid, overweight, arterial blood pressure, use of oral contraceptives (in women), consumption of alcohol and tobacco, and lack of physical exercise. These factors were classified as a function of their discriminative power by the statistical method of segmentation. We thus chose the following factors as criteria for exclusion from a reference population for the values of triglycerides in blood: in men 20 to 39 years old, overweight more than 90%; in men 40 to 59 years old, overweight of more than 115%, consumption of more than half a liter of wine per day or of more than 11 cigarettes, use of medicines, and a blood uric acid exceeding 420 mumol/L; in women 20 to 39 years old, contraceptives and overweight; in women 40 to 59 years old, overweight or more than 130% and the intake of medicines. At the 97.5th percentile of the reference population as compared with a non-selected population, the values were 80% less for men 20 to 39 years old, 95% less for men 40 to 59 years old, and only 26 to 30% less for women 20 to 59 years old. |
