食土癖作为一种传播土源性蠕虫的方法可能是有害的。在这项研究中，我们提出了两个问题，在一个有代表性的样本970名孕妇从奔巴岛，桑给巴尔，坦桑尼亚。被消耗的泥土能成为土源性蠕虫感染的媒介吗？食土者有不同的寄生虫感染吗？分析了59个非食品物质样品的寄生虫含量。通过当地研究人员进行的访谈收集了关于异食癖行为的横截面数据，并通过加藤-卡茨涂片确定了蛔虫、鞭虫和钩虫状况。基线时食土癖的患病率为5.6%，蛔虫、鞭虫和钩虫的总患病率分别为5.6%、33.2%和32.9%。消费的土壤样本中没有含有传染性寄生虫阶段，只有一种消费的异食癖物质（木炭）含有对人类健康有潜在风险的寄生虫。在双变量分析中，蛔虫、鞭虫或钩虫的感染率和感染强度均无显著性差异。此外，在多变量模型中，食土癖并不是蠕虫感染状态的重要预测因素。我们的结论是，食土癖不是奔巴孕妇鞭虫钩虫感染的来源（没有足够的能力来评估蛔虫的影响），这与蠕虫感染和食土癖的现有研究结果相反。
Geophagia may be harmful as a method for the transmission of geohelminths. In this study, we pose two questions in a representative sample of 970 pregnant women from Pemba Island, Zanzibar, Tanzania. Can consumed earth be a vector for geohelminth infection? And do geophagists have differential parasitic infection? The parasitological content of 59 non-food substance samples was analysed. Cross-sectional data regarding pica behaviour were collected through interviews conducted by local researchers.Ascaris,Trichurisand hookworm status was ascertained through Kato—Katz smears. The prevalence of geophagia at baseline was 5.6% and the overall prevalence ofAscaris,Trichurisand hookworm infection was 5.6%, 33.2% and 32.9%, respectively. No consumed soil samples contained infectious parasitic stages, and only one of the consumed pica substances (charcoal) contained parasites of potential risk to human health. In bivariate analyses, neither the prevalence nor the intensity of infection withAscaris,Trichurisor hookworm differed significantly by geophagia status. Furthermore, in multivariate models, geophagia was not a significant predictor of helminth infection status. We conclude that geophagia is not a source ofTrichurisor hookworm infection among pregnant women in Pemba (insufficient power to evaluate the effect ofAscaris), which is in contrast to existing findings of helminth infection and geophagia.
