[Structure of nutrition of one of Moscow's districts and its relationship to risk factors of chronic noninfectious diseases from the standpoint of medical prevention].

Dietary intake was studied in 295 of Moscow's residents by 24-hour recall method. High level of animal fat, sugar and cholesterol (Ch) were found in diet of man and women. Energy intake of men is higher than that of women at the expense of animal fat and protein.

Nonlinear relationship between erythrocyte sodium-lithium countertransport and blood pressure in man.

A relationship between erythrocyte Na+/Li(+)-countertransport activity and blood pressure was studied in a randomly selected sample (95 subjects) with full range of blood pressure, from a representative group of inhabitants of one of Moscow's districts. The mean rate of erythrocyte Na+/Li(+)- countertransport activity was higher (p < 0.01 or less) in the groups of subjects with both borderline (BH) and moderate essential hypertension (EH) as compared with the group of normotensives (NT).

[Arterial pressure, physical activity and physical work capacity].

A representative population sample was studied to elucidate relationships of arterial pressure (AR) with muscular performance (MP) and arterial hypertension risk factors. Power working capacity (PWCx) was measured by means of exercise tolerance test at rest, under physical loading and after the exercise. The findings were processed using a multivariate step-by-step regression analysis which established independent relations between exercise and postexercise MP and arterial hypertension.

[The relation of physical work capacity to the arterial pressure level and risk factors for arterial hypertension].

A multivariate regression analysis including muscular performance, arterial pressure, age, heart rate, body-weight index permitted identification of independent relations between pressure and muscular performance. The latter accounts for 3% variability in initial systolic pressure in females and for 3% variability in males under physical loading. Initial systolic pressure accounts for 5% variability of muscular performance in females.
