Сравнительная оценка уровня стигматизации сельских и городских обучащихся как критерий неблагоприятного воздействия техногенного загрязнения

Abstract

The article deals with the data of a comparative evaluation of the level of stigmatization of learners who were born and raised in urban and rural areas. Statistically significant differences were identified both in the frequency of occurrence of small anomalies of development as well as in the level of stigmatization of the examined students. In particular, in the group of urban students the frequency of occurrence of small anomalies of development made up 67.27%, whereas rural students – 52%. The average level of stigmatization in the first group made up 3.71 ± 0.43, in the second – 2.10 ± 0.24 (p < 0.05). The examined students had differences in the number of demonstrated dysgenesis. Therefore, in the group of urban students there were 34 types of small anomalies of development, and in the rural group there were 28 species respectively. The most widespread dysgenesis of urban students there were anomalies of the limbs, back, ears and teeth. The varieties of small anomalies of development of rural students were somewhat different, since in this group the most peculiar there were anomalies of limbs and teeth. Statistically significant differences of indexes of frequency of occurrence of small development anomalies of urban and rural students led to the conclusion that the urban environment, which is characterized by a higher level of anthropogenic pollution, has an unfavorable influence on the perinatal stage of the organism development. The received data indicate that the period of formation of the structures of the musculoskeletal system is a very vulnerable period of perinatal ontogenesis to the negative influence of exogenous factors.
