AIM:To evaluate the relationships between the personal,sociocultural,and environmental characteristics,and thepresence or absence of symptoms with the detection ofEnterobius vermicularis(E.vermicularis)in a populationsample in our region(General Mansilla,Province of BuenosAires,Argentina),by individual and familiar analyses.METHODS:E.verrnicularis was diagnosed in 309 peoplefrom 70 family units residing in the urban area and therural area of the city of General Mansilla.Each of themwas surveyed so as to register personal,environmentaland sociocultural data.Questions about the presence orabsence of anal itch,abdominal pain and sleeping disorderwere also asked.Significant associations were determinedby square chi tests.Logistic regression models wereadjusted by using a backward conditional stepwise methodto determine the presence of this parasite in the individualsand 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 significantassociation were affiliation,where the risk category was“being the son/daughter of”,and the symptoms wereabdominal pain,sleeping disorder,and anal itch.Familieswith a member infected with parasite were consideredPositive Families(PF)and they were 40/70(57.14%),only5%(2/40)of the PF had 100% of their members infectedwith the parasite.The logistic regression models applied showedthat the risk categories were mainly affiliation(son/daughter)and housing(satisfactory)among others.CONCLUSION:The presence of E.vermiculariswas provedin one third of the studied population.The frequency offamilies with all their members infected with the parasitewas very low.Most of the studied personal,sociocultural,and environmental variables did not turn out to be significantlyassociated with the presence of the parasite.An association with the category of“son/daughter”and housing classifiedas“satisfactory”was determined.The latter may be due tothe fact that the people living in that category of housinghave hygienic practices at home that favour the distributionof the eggs in the environment.The presence of the analysedsymptoms was associated with the presence of the parasite,thus strengthening the need of periodical control of thepopulation showing at least one of these symptoms.

METHODS: E.verrnicularis was diagnosed in 309 peoplefrom 70 family units residing in the urban area and therural area of ​​the city of General Mansilla .ach of themwas surveyed so as to register personal, environmentaland sociocultural data.Questions about the the presence orabsence of anal itch, abdominal pain and sleeping disorderwere also asked.Signific regression models wereadjusted by using a backward conditional stepwise methodto determine the presence of this parasite in the individualsand in the families .RESULTS: The parasites were found in 29.12% (90/309) of the individuals, with a frequency of 14.28% (20/140) am ong the heads of the families and of 41.42% (70/169) among the children. The only variables showing a significantassociation were affiliation, where the risk category was “being the son / daughter of”, and the symptoms wereabdominal pain, sleeping disorder , and anal itch. Familieswith a member infected with parasite were consideredPositive Families (PF) and they were 40/70 (57.14%), only5% (2/40) of the PF had 100% of their members infectedwith the parasite.The logistic regression models applied showedthat the risk categories were mainly affiliation (son / daughter) and housing (satisfactory) among others.CONCLUSION: The presence of E.vermicularis was provedin one third of the studied population. the frequency offamilies with all their members infected with the parasitewas very low. Most of the studied personal, sociocultural, and environmental variables did not turn out to be significantlyassociated with the presence of the parasite. An association with the category of “son / daughter” and housing classifiedas “Satisfactory ”was determined. the latter may be due tothe fact that the people living in that category of housinghave hygienic practices at home that favor the distributionof the eggs in the environment. The presence of the analysedsymptoms was associated with the presence of the parasite, thus strengthening the need of periodical control of thepopulation showing at least one of these symptoms.
