The deprived area of the Metzinger Valley in the city of Mahajanga has many healthcare concerns due to repeated flooding during the rainy season. Improving this health situation requires a better knowledge of the pathogens present in this area and of the risk factors favoring their propagation. The aim of this study was to analyze the relationship between the household socioeconomic status and the presence of parasites in the faeces of children between 1 and 10 years of age in order to determine the risk factors for intestinal parasitosis. The study included 746 children, of whom 30% were infected with parasites. , a good indicator of environmental fecal contamination, was the most prevalent parasite with an observation frequency of 16.7% followed by with a prevalence of 10%. For helminths, and were the most prevalent respectively 5.4% and 1.8%. A large heterogeneity in the prevalence of parasites was observed from one neighborhood to another. However, multivariate analysis showed that these differences were not related to environmental factors or household structure, but rather to the economic level of the family, the education level of the mother as well as the age of the child. For example, the prevalence of decreased from 23.5% to 8% for children of mothers with little education to those with higher education, respectively. For , the prevalence is higher among poor households and school-aged children. In the frame of IRCOD project, mothers are being sensitized to hygiene and risk factors for transmission by intestinal parasites and the present study proposes a multidimensional approach as an assessment tool.
马哈赞加市梅青格山谷的贫困地区因雨季反复遭受洪水侵袭而存在诸多医疗保健问题。要改善这一健康状况，需要更好地了解该地区存在的病原体以及有利于其传播的风险因素。本研究的目的是分析家庭社会经济状况与1至10岁儿童粪便中寄生虫存在情况之间的关系，以确定肠道寄生虫病的风险因素。该研究纳入了746名儿童，其中30%感染了寄生虫。作为环境粪便污染的一个良好指标， 是最常见的寄生虫，观察频率为16.7%，其次是 ，患病率为10%。对于蠕虫， 和 分别是最常见的，患病率分别为5.4%和1.8%。从一个街区到另一个街区，寄生虫患病率存在很大差异。然而，多变量分析表明，这些差异与环境因素或家庭结构无关，而与家庭经济水平、母亲的教育水平以及孩子的年龄有关。例如，母亲受教育程度低的孩子中 的患病率从23.5%降至母亲受教育程度高的孩子中的8%。对于 ，贫困家庭和学龄儿童中的患病率较高。在IRCOD项目框架内，母亲们正在提高对卫生以及肠道寄生虫传播风险因素的认识，本研究提出了一种多维度方法作为评估工具。
