The prevalence of intestinal parasites was studied as a function of socioeconomic conditions within La Plata, Argentina. Age, sex, and environmental factors were considered. Thus, from each of three areas within the city - the first a 'marginal' zone, the second a lower-income suburb, the third a middle-income urban district - 100,101, and 91 children up to 14 years old, respectively, were examined for intestinal parasites. Giardia lamblia was the most frequent species found. The respective prevalences of intestinal parasites overall (73, 54.4, and 35.1%), of polyparasitism (61.6, 27.2, and 12.5%), and of helminthic infection (32, 10.9, and 0.0%) were the highest within the population group having significantly inferior sanitary and environmental conditions. A positive statistical association between the prevalence of intestinal parasitosis and age was observed in all three of the neighborhoods. We also noted a correspondence between the frequency of such infections and school attendance in the two suburban districts. Management practices in accordance with the specific characteristics of an urban environmental and sociocultural ecosystem are thus important for the control of intestinal-parasite infection within municipal populations.
在阿根廷拉普拉塔市，研究了肠道寄生虫的流行情况与社会经济状况之间的关系。研究考虑了年龄、性别和环境因素。因此，从该市的三个区域——第一个是“边缘”区，第二个是低收入郊区，第三个是中等收入市区——分别对100名、101名和91名14岁以下儿童进行了肠道寄生虫检查。蓝氏贾第鞭毛虫是最常见的发现物种。在卫生和环境条件明显较差的人群组中，肠道寄生虫总体患病率（分别为73%、54.4%和35.1%）、多重寄生虫感染率（分别为61.6%、27.2%和12.5%）以及蠕虫感染率（分别为32%、10.9%和0.0%）最高。在所有三个社区中，均观察到肠道寄生虫病患病率与年龄之间存在正相关统计关联。我们还注意到，在两个郊区，此类感染的频率与上学情况之间存在对应关系。因此，根据城市环境和社会文化生态系统的具体特点采取管理措施，对于控制城市人口中的肠道寄生虫感染非常重要。
