Comparison of microecological intestinal indices in children with different value of body mass index

Abstract

The body mass index (BMI) is one of the key and at the same time simple and significant indicators of the state of the human body. Both large and small quantities of BMI is associated with high morbidity. The aim of the study was to analyze microecological disorders of intestinal biocenosis in children of different ages using the value of BMI as the criterion of comparison. We researched scatological material from 158 children and adolescents aged from 5 to 17 years (77 boys and 81 girls). The material was divided into three comparison groups depending on the BMI value: group 1 - body mass deficit (n = 34); group 2 - patients having body mass excess (n = 37); group 3 - with normal body mass (n = 87). It has been shown that more than 80 % of children with different BMI value were recorded to have dysbiotic disturbances of the intestinal microbiota of degrees 1 and 2. However, in the group of children with normal body mass, frequency of detection of intestinal dysbiosis was significantly lower; in the group of children with underweight dysbiotic disorders were found significantly more often than in overweight and obese children (p < 0.05). In children with body mass deficit we observed not only increasing concentration of opportunistic pathogenic bacteria, but also an increased occurrence of representative of Enterobacteriаceaе. family. 58.8 % of cases had two- and three-component associations of opportunistic pathogenic bacteria, which is an indication the expressed violations of the intestine microbiocenosis formation. The data obtained show that,you can use BMI, an important criterion reflecting the severity of the disease, in the assessment of intestinal microflora in combination with other studies.
