title: [The prevalence of Enterobius vermicularis in schoolchildren and affecting factors].
abstract: This study was carried out in order to determine the factors affecting the presence of Enterobius vermicularis in schoolchildren. This investigation was a cross-sectional and analytic study. The dependent variable was the presence of parasites and the independent variables were the characteristics of the children, families, houses, toilets and drinking water. A stool specimen was taken in the morning using the cellophane tape method, and examined the same day by microscopy. Data were evaluated using the Chi square test and logistic regression analysis and p < 0.05 was accepted as being statistically significant. There were 529 students in the kindergarten and 1-5 classes in the Isikkent and Sait Guzelcan primary schools in the region of the Isikkent Health Center in Izmir. However specimens could only be obtained from 477 (90.2%) students. The mean age of children was 8.6+/-2.0 years. The number of residents in their homes averaged 5.4+/-2.0, the average number of children in the homes was 3.2+/-1.9 and 290 (60.8%) houses were single dwellings. The source for piped water in 404 houses (84.7%) was the city network, and there were modern sanitary facilities (toilets) in 377 (70.6%) houses. Enterobius vermicularis was found in 209 (43.8%) children. According to logistic regression analyses, the rate of Enterobius vermicularis was found to be 3.05 times higher in students from the Sait Guzelcan primary school, if there were more than 6 residents in the home 2.05 times even higher and 2.02 times still higher if there were no sanitary facilities at his/her home. When there was a history of parasites in the family, the risk was significantly decreased. The prevalence of Enterobius vermicularis in schoolchildren was higher in slum areas, in crowded homes and in those that lacked modern sanitary facilities.
