To investigate the epidemiology of Schistosoma mansoni infection among pregnant women in a secondary-care hospital in Geizera state, Sudan.
Between August and September 2010, a cross-sectional study was conducted and questionnaires were administered to obtain basic sociodemographic and obstetric characteristics of pregnant women attending prenatal care at Araba Waeshreen Hospital. Stool samples were investigated for helminth infection via formol-ether concentration and Kato-Katz techniques.
Of 292 pregnant women, 38 (13.0%) had S. mansoni infections. Hymenolepis nana and hookworm infections were present in 5 (1.7%) and 1 (0.3%) women, respectively. The intensity of the S. mansoni infection was light, moderate, and high in 13 (34.2%), 21 (55.3%), and 4 (10.5%) women, respectively. In multivariate analyses, parity, gestational age, and occupation were not associated with S. mansoni infection, unlike maternal age less than 20 years (odds ratio [OR] 9.8; 95% confidence interval [CI], 1.5-16.3; P=0.01) and no education (OR 6.2; 95% CI, 2.8-12.9; P<0.001).
There was a high level of S. mansoni infection among pregnant women in the present setting, especially among younger women and those with no education. Control and preventive measures should be used in the area.
调查苏丹盖宰拉州二级保健医院孕妇曼氏血吸虫感染的流行病学情况。
2010 年 8 月至 9 月，采用横断面研究方法，对在阿拉巴瓦希林医院接受产前护理的孕妇进行问卷调查，获取其基本社会人口学和产科特征。采用福尔马林-乙醚沉淀法和加藤厚涂片法检查粪便样本中的寄生虫感染情况。
在 292 名孕妇中，有 38 名（13.0%）患有曼氏血吸虫感染。5 名（1.7%）和 1 名（0.3%）孕妇分别患有囊尾蚴和钩虫感染。13 名（34.2%）、21 名（55.3%）和 4 名（10.5%）孕妇的曼氏血吸虫感染强度分别为轻度、中度和重度。在多变量分析中，与产次、妊娠年龄和职业不同，母亲年龄小于 20 岁（比值比 [OR] 9.8；95%置信区间 [CI]，1.5-16.3；P=0.01）和未接受教育（OR 6.2；95% CI，2.8-12.9；P<0.001）与曼氏血吸虫感染无关。
在当前环境下，孕妇中存在较高水平的曼氏血吸虫感染，尤其是年轻女性和未受教育的女性。应在该地区采取控制和预防措施。
