Introduction. According to statistics, the health of modern Russian schoolchildren has a stable negative trend associated with an increase of the prevalence of chronic diseases, and with decrease of the proportion of healthy children in all age groups. It is also known, that environment and social factors, either alone or in combination, despite the differences in their nature, can be complex and ambiguous effects on physical development (FD) of the body, including and deferred. According to some data the study of the features of risk factors of children and adolescents indicate intensification of social stratification and requires further monitoring of public health. Objectives. The aim of this study is a comparative analysis of FD of children and adolescents living in rural regions with varying degrees of pollution and with different levels of socio-economic well-being. Material and methods. For obtain of anthropometric data was used method of cross-sectional of population. 2,457 children of three age groups were explored: younger (6–9 years), medium (10-14 years), and senior (15–18 years). Measurements of total body size (height, weight, chest circumference) were produced by conventional methods. FD level was assessed by body mass index, Quetelet (BMI). Type of FD harmony was determined by centile scale. The exploring was conducted in 6 rural areas of one region which differed by quality of habitat (QH) and by level of socio-economic development (SED). The results showed that the risk factors of senior children and adolescents are associated mainly with QH, while FD of most young children with the level of SED. When comparing the performance of conjugation FD with QH and SED depending on the sex of the child, it should be recognized that the boys is more sensitive to environmental factors, and girls - to the influence of social factors. Conclusion. It was found that the influence of environmental factors appears in change the FD of senior children and the influence of social factors in change the FD of young children. Comparative analyses of the factors which may influence on the overall body size indicate that male children are more sensitive to the effects of environmental factors, female children, on the contrary, to the effects of social factors. Thus, environmental and social factors can cause multidirectional and (or) combination effects of influence on the anthropological parameters of children of different age and sex.
