METHODS:E.verrnicularis was diagnosed in 309 people from 70 family units residing in the urban area and the rural area of the city of General Mansilla.Each of them was surveyed so as to register personal,environmental and sociocultural data.Questions about the presence or absence of anal itch,abdominal pain and sleeping disorder were also asked.Significant associations were determined by square chi tests.Logistic regression models were adjusted by using a backward conditional stepwise method to determine the presence of this parasite in the individuals and in the families. RESULTS:The parasites were found in 29.12%(90/309) of the individuals,with a frequency of 14.28%(20/140) among the heads of the families and of 41.42%(70/169) among the children.The only variables showing a significant association were affiliation,where the risk category was “being the son/daughter of”,and the symptoms were abdominal pain,sleeping disorder,and anal itch.Families with a member infected with parasite were considered Positive Families(PF)and they were 40/70(57.14%),only 5%(2/40)of the PF had 100% of their members infected with the parasite.The logistic regression models applied showed that the risk categories were mainly affiliation(son/daughter) and housing(satisfactory)among others. CONCLUSION:The presence of E.vermiculariswas proved in one third of the studied population.The frequency of families with all their members infected with the parasite was very low.Most of the studied personal,sociocultural, and environmental variables did not turn out to be significantly associated with the presence of the parasite.An association with the category of“son/daughter”and housing classified as“satisfactory”was determined.The latter may be due to the fact that the people living in that category of housing have hygienic practices at home that favour the distribution of the eggs in the environment.The presence of the analysed symptoms was associated with the presence of the parasite, thus strengthening the need of periodical control of the population showing at least one of these symptoms.展开更多
