[The development of cholesterolemia in the Czech population 1985-1988].

The authors followed up the development of serum cholesterol levels in the population aged 25-64 years in six districts of the CR. These districts collaborate since 1984 in the international WHO programme, MONICA. The mean total cholesterol levels increased during 1985-1988 in men from 6.21 mmol/l to 6.28 mmol/l (ns), in women from 6.18 mmol/l to 6.22 mmol/l (ns). During the same period in the population of the six districts the number of subjects with total cholesterol values of 5.2 mmol/l or less declined from 21.9% to 16.8% (p less than 0.001) in men and from 24.0% to 19.4% in women (p less than 0.01). It is important that the greatest change was recorded in the age group of 25-34 years--in men from 38.7% to 27.7% (p less than 0.01) and in women from 46.6% to 36.7% (p less than 0.05). In the investigated population in 1988 cholesterol levels of 6.5 mmol/l and more were recorded in 39.4% of the men and 36.9% of the women, values of 7.8 mmol/l and more in 10% of the men and 9.6% of the women. If in our population, within the framework of prevention of IHD, recommendations of the European Society for Atherosclerosis will be applied, preventive provisions will be necessary in more than 80% of the adult population.
