The aim of this study was to analyze the prevalence of Toxocara spp. antibodies in children from two different socioeconomic classes in the Presidente Prudente municipality, São Paulo State, Brazil, and the protective and risk factors associated with toxocariasis. One hundred and twenty-six middle-class (MC) and 126 disadvantaged children (DC) were included in this study. Anti-Toxocara ELISA test was performed in order to evaluate seroprevalence. A survey was applied to the children's guardians/parents in order to analyze the protective and risk factors. The overall prevalence was 11.1%, and of 9.5% (12/126) and 12.7% (16/126) for MC and DC subgroups, respectively. Toxocara seropositivity was inversely proportional to the family income. A high household income was considered a protective factor for toxocariasis in the total population and in both MC and DC subgroups. Being a girl was considered a protective factor for the total population and for both subgroups. Whilst being an owner of cat was a risk factor for children belonging to the total and for both MC and DC subgroups, having dog was considered as a risk factor for only the MC. Epidemiologic protective/factor risks can be distinct depending on the strata of the same population. Thus, it is relevant to evaluate these factors independently for different socioeconomic classes in order to design future investigations and programs for preventing the infection of human beings by Toxocara spp. and other geohelminths.
本研究旨在分析巴西圣保罗州普鲁登特总统市两个不同社会经济阶层儿童体内弓首蛔虫属抗体的流行情况，以及与弓首蛔虫病相关的保护因素和风险因素。本研究纳入了126名中产阶级（MC）儿童和126名弱势儿童（DC）。进行了抗弓首蛔虫ELISA检测以评估血清阳性率。对儿童的监护人/父母进行了一项调查，以分析保护因素和风险因素。总体流行率为11.1%，MC亚组和DC亚组分别为9.5%（12/126）和12.7%（16/126）。弓首蛔虫血清阳性率与家庭收入成反比。高家庭收入被认为是总体人群以及MC和DC亚组中弓首蛔虫病的保护因素。女性被认为是总体人群以及两个亚组的保护因素。养猫是总体人群以及MC和DC亚组儿童的风险因素，而养狗仅被认为是MC亚组的风险因素。同一人群不同阶层的流行病学保护/风险因素可能不同。因此，为了设计未来预防人类感染弓首蛔虫属和其他土源性蠕虫的调查和项目，针对不同社会经济阶层独立评估这些因素具有重要意义。
