目的：为了验证学龄前儿童肠道寄生虫感染的患病率，并确定相关的危险因素。方法：本研究是一项横断面研究嵌套在一个队列的儿童出生和居住在迪亚曼蒂纳，米纳斯吉拉斯，巴西。在研究时，所有儿童的年龄均为60个月+/-5个月。在获得父母或监护人的书面知情同意书后招募他们。该研究于2009年7月至2010年7月期间进行。共有214名儿童提供粪便样本进行肠道寄生虫感染检查。通过问卷调查，从儿童的父母和监护人处获得有关寄生虫病潜在危险因素的信息。结果：肠道寄生虫感染率为27.5%（n=59）。男生感染率（26.1%，n=36）略低于女生（30.3%，n=23），但差异无统计学意义（p=0.51）。14名儿童（23.7%）感染两种或两种以上寄生虫，45名（76.3%）感染单一寄生虫。家庭人均收入低与感染风险增加密切相关（OR=2.89; P=0.003）。结论：肠道寄生虫感染是迪亚曼蒂纳学龄前儿童的一个健康问题。贫穷被认为是感染的一个重要风险因素，而母亲全职在家则是一个保护因素。
Objective: To verify the prevalence of intestinal parasitic infections among preschoolers and to identify the associated risk factors.Methods: The study is a cross-sectional study nested in a cohort of children who were born and resident in Diamantina, Minas Gerais, Brazil. At the time of the study, all children were aged 60 months +/- five months. They were recruited after written informed consent was obtained from parents or guardians. The study was carried out between July 2009 and July 2010. In total 214 children provided a stool sample for examination on intestinal parasitic infections. Information on potential risk factors for parasitosis was obtained from parents and guardians of the children by a questionnaire. Logistic regression was used for analysis.Results: Intestinal parasitic infections were found in 27.5% (n=59) of children. The boys' infection prevalence (26.1%, n=36) was slightly lower than the infection prevalence of the girls (30.3%, n=23), but not statistically different (p=0.51). Fourteen children, (23.7%) were infected with two or more parasite species and forty-five (76.3%) with single parasites. A low per capita income of family was strongly associated with an increased risk for an infection (OR=2.89; P=0.003). Preschoolers whose mothers did not work outside home had a significantly lower risk for infection (OR=0.41; p=0.01).Conclusion: Intestinal parasite infection is a health problem among Diamantina preschoolers. Poverty was implicated as an important risk factor for infection, while the presence of the mother at home full-time was a protective factor.
