[The frequency of intestinal parasites in primary school children in urban and rural regions].

The aim of this study was to determine the prevalence of intestinal parasites in primary school children in Sivas and to consider the changes in frequency and variety of intestinal parasites in the light of previous studies carried out since 1985. Specimens were examined by direct microscopy and staining. In addition, the relationship of intestinal parasites with physical development, success and socio-economic situation was investigated using surveys. Intestinal parasites were found in 191 (26.2%) of 730 stool specimens, 88 (12.9%) of cellophane tape specimens and parasites were found in both types of specimens obtained from 251 (37.1%) out of 677 students. The most common five parasite species were Giardia intestinalis (13.7%), Enterobius vermicularis (12.8%), Entamoeba coli (7.4%), Blastocystis hominis (2.2%) and Hymenolepis nana (1.2%). Intestinal parasites were most frequently detected in the Celtek Village Primary School (50.0%). This school was followed by Imranli YIBO School (45.7%), 60.Yil Primary School (36.3%) and Koyulhisar YIBO (21.3%) School. We found that there was no statistically important relationship between the occurrence of parasites with weight, length and success. It was related to the socioeconomic situation. Furthermore, in this region when the previous studies in similar age groups are considered, a decrease in intestinal parasites frequency and variety was revealed.
