In order to study the factors related to Enterobius infection among per-schoolchildren, a structural questionnaire with multi-stages and a random sampling was designed to interview parents of 702 pre-schoolchildren. The questionnaire included personal information of the children: their educational background and parents' occupation; the status of their housing; their handwashing habits, and their frequency and habits of bathing, etc. In addition, the children's pinworm infections were examined using two-consecutive-day adhesive cellophance paper perianal swabs. Variables causing the pinworm infection among infected and noninfected children were analyzed by x2-test and multi-variable tests including discriminant analysis and stepwise multiple regression.
