An epidemiological survey was conducted among men aged 40 to 59 to study interrelationships of the nutritional patterns in 2 ethnic groups of population and the prevalence of CHD and risk factors of its development. The nutritional habits of the indigenous Kirghiz population in the city of Frunze differed significantly from those of the alien population (Russians, Ukrainians, etc.) and were characterized by a higher consumption of proteins and complex carbohydrates. Nutrition of the alien population included mostly simple carbohydrates: sugar, fat and monounsaturated fatty acids. Coronary heart disease, arterial hypertension, smoking, excess body mass, low physical activity were equally common among the Kirghiz and Europeans. Hypercholesterinemia was noted more frequently in Europeans whereas hypertriglyceridemia was more common among the Kirghiz.
