[Quality of life of obese preschoolers].

The prevalence of obesity in childhood and adolescence tends to increase, and its presence is associated with a change in the quality of life (QOL). Nevertheless, the question of the influence of obesity on the QОL of Russian children in preschool years remains unexplored, while this age refers to the period of obesity manifestation. Purpose of the study - to examine the quality of life of preschool children with obesity and determine the optimal methods of disease preventing.

[Analysis of actual home nutrition of urban children of pre-school and school age].

The actual nutrition of the child population reflects the influence of both the socioeconomic conditions in the country and the local social environment of the child, while forming a reserve of adaptive opportunities and health in general. Aim. Analysis of the actual home nutrition of urban children of preschool and school age.

[The effectiveness of the improvement of health in the schoolchildren staying in a country summer camp].

Unlabelled: Organization of recreational activities in the children's camps is inseparable from the assessment of their effectiveness.

Aim: The objective of the present study was to estimate the influence of the pastime of the children in a summer camp under the habitual climatic conditions and the resulting improvement of their health status including the body component composition and the functional state of the organism.

Material And Methods: The study included 44 schoolchildren at the age from 9 to12 years.

[Forecasting a risk of occupationally related diseases in workers engaged into titanium-magnesium production].

Workers of titanium and magnesium production, under occupational exposure to complex of chemical (chlorine, hydrochloride, sulfur dioxide) and physical factors (industrial noise, work hardiness), have arterial hypertension as occupationally related disease, when length of service over 15 years (EF = 71,5%), and nasopharyngitis for length of service over 10 years (EF = 65%). Arterial hypertension risk is mostly associated with increased industrial noise level (F = 1621; R2 0.95; p < 0,001; noise 70,1 dB).

[New potential of MTHFR gene variations application as an individual sensitivity marker in evaluation of occupational risk of arterial hypertension under exposure to nose].

The article deals with results of assessing risk of occupationally related hypertension among workers of sylvinitedressing works, with individual sensitivity consideration. Epidemiologic study proved correlation between occupational exposure to noise over 83 dB and hypertension and its predictors - increased activity of serum lipoprotein and homocystein. The studies determined an indicator of the workers' increased sensitivity to arterial hypertension development and to changes in parameters of disordered vascular tone regulation (increased activity of serum lipoprotein and homocystein) under exposure to noise - CT genotype of MTHFR gene.
