This study aimed to estimate the prevalence and investigate the factors associated with intestinal parasitic diseases in children from an urban slum in Brazil.
A cross-sectional study was conducted in children living in SEWA community, an urban slum located in Araguari, Minas Gerais, Brazil. The prevalence of intestinal parasitosis was determined via stool parasitological examination by spontaneous sedimentation. Socioeconomic, demographic, and behavioral data were collected to identify associated factors. The statistical analysis used the Poisson regression model, with robust variance for identification of associations.
Fifty-two children were interviewed, 41 of whom underwent parasitological examination. The prevalence of intestinal parasitosis was 43.9% (95% confidence interval - 95%CI 34.6-51.4), and 23% of children presented polyparasitism. Endolimax nana, Entamoeba coli, Giardia lamblia and Strongyloides stercoralis were identified in the stool samples. The adjusted analysis indicated negative associations of parasitosis with annual parasitological examination, possession of private health insurance, a mother who was married or in a stable relationship, and access to water treatment. Positive associations were observed with male sex, habit of playing with dirt, water ingestion from the hose, unemployed parents, low parental education, and the presence of a septic tank at home.
The high prevalence of intestinal parasitosis in the SEWA community is a public health problem. The identification of modifiable and preventable factors highlights the need for interventions to improve living conditions not only for children but also for the entire community.
本研究旨在估计巴西一个城市贫民窟儿童肠道寄生虫病的患病率，并调查与之相关的因素。
在巴西米纳斯吉拉斯州阿拉瓜里市一个名为SEWA社区的城市贫民窟居住的儿童中开展了一项横断面研究。通过自然沉淀法进行粪便寄生虫学检查来确定肠道寄生虫病的患病率。收集社会经济、人口统计学和行为学数据以识别相关因素。统计分析采用泊松回归模型，并采用稳健方差来识别关联。
共访谈了52名儿童，其中41名接受了寄生虫学检查。肠道寄生虫病的患病率为43.9%（95%置信区间 - 95%CI 34.6 - 51.4），23%的儿童存在多重寄生虫感染。在粪便样本中鉴定出了微小内蜒阿米巴、结肠内阿米巴、蓝氏贾第鞭毛虫和粪类圆线虫。校正分析表明，寄生虫病与年度寄生虫学检查、拥有私人医疗保险、母亲已婚或处于稳定关系以及获得水处理呈负相关。观察到与男性性别、玩泥土的习惯、从软管中饮水、父母失业、父母教育程度低以及家中有化粪池呈正相关。
SEWA社区肠道寄生虫病的高患病率是一个公共卫生问题。可改变和可预防因素的识别凸显了不仅针对儿童而且针对整个社区改善生活条件的干预措施的必要性。
