Comparison of bioimpedance body composition in young adults in the Russian Children's Study.

Background & Aims: Body mass index is a simple anthropometric measure (kg/m) used as an indirect estimate of body fat in individuals, and in assessments of population health and comparisons between populations. Bioelectrical impedance analysis (BIA) is often used to provide additional information on body fat and fat-free mass, and has been used to generate body composition reference data in national health surveys. However, BIA measurements are known to be device-specific and there are few published studies comparing results from different BIA instruments.

[Issues of healthy life style in the professional preparation of the physician].

The main value orientations of medical students are directly or indirectly associated with various components of health. On the other hand, the knowledge of the predominating effect of life style on health, hazards of nicotine and alcohol did not become a persuasion in the majority of students, and high value of health did not transform into motivation forits preservation. That is why special attention in the training of physicians should be paid to the formation of practical habits of fundamentals of healthy life style.

[Pregnancy outcomes in women with a pathological weight gain, vascular dysfunction, transitory edemas and transient proteinuria].

A total of 750 pregnant women were examined by the blind screening method at terms of 7-16, 18-24, 28-36, 38-41 weeks and on day 2 after delivery. A high and medium-high reliable correlation between the laboratory instrumental parameters characterizing vascular disorders and pathological weight gain, symptoms of vascular dysfunction, transitory edema and proteinuria has been revealed. These symptoms were shown to occur not only in gestoses, but in cases with small-for-date fetuses, early detachment of normally positioned placenta, miscarriages, and prolonged gestation.

[Cardiac diastolic function in children and adolescents during prompt and long-term adaptation to physical exercise].

To study the natural changes in cardiac diastolic function in ontogenesis at various stages of exercise adaptation, 65 males aged 10-17 years who go in for various kinds of sports developing primarily physical fitness have been examined. Long-term adaptation to cyclic muscular activity has been shown to result in a reduction in cardiovascular lability, an optimization of inclusion of myocardial functional reserves, and an increase in efficiency of using cardiac cycle time in response to myocardial restorative processes. High stages of exercise adaptation formed an additional mechanism responsible for diastolic filling at the expense of an atrial systole (an atrial mechanism of diastolic regulation).
