Abstract

Background: Polyparasitic infections remain widespread in endemic regions, yet its contributing factors and health impact are not well understood. This study aims to estimate the prevalence and associated factors and examines the effect of polyparasitic infection on haemoglobin levels among children.

Methods: A cross-sectional study was conducted in Lambaréné, Gabon, among children aged 2-17 years from November 2019 to December 2020. Haemoglobin levels, environmental conditions, and sociodemographic data were collected. Stool, urine, and blood samples were analysed using light microscopy for parasite detection. Factors associated with polyparasitism were explored.

Results: Out of 656 participants, 65.4% had at least one infection, with intestinal protozoa species (21.3%), Trichuris trichiura (33%), Ascaris lumbricoides (22%), Schistosoma haematobium (20%), and Plasmodium falciparum (10%) being the most common. Polyparasitic infection was identified in 26% of children, mostly as bi-infections (69.2%), and was negatively associated with haemoglobin levels (β = -0.06).

Conclusions: These findings emphasise the burden of polyparasitic infections and adverse health effects in Lambaréné, Gabon.

多寄生虫感染：生活在加蓬兰巴尼什和偏远及周边农村地区儿童血红蛋白水平的相关因素和影响——横断面研究

背景：多寄生虫感染在流行地区仍然普遍存在，但其致病因素和对健康的影响尚不清楚。本研究旨在估计儿童多寄生虫感染的患病率和相关因素，并探讨多寄生虫感染对血红蛋白水平的影响。方法：于2019年11月至2020年12月在加蓬lambar - n地区对2-17岁儿童进行横断面研究。收集血红蛋白水平、环境条件和社会人口数据。使用光学显微镜对粪便、尿液和血液样本进行寄生虫检测分析。探讨了与多寄生相关的因素。结果：656名参与者中，65.4%至少有一种感染，其中肠道原生动物（21.3%）、毛滴虫（33%）、蛔虫（22%）、血血吸虫（20%）和恶性疟原虫（10%）最为常见。在26%的儿童中发现了多寄生虫感染，主要是双感染（69.2%），并且与血红蛋白水平呈负相关（β = -0.06）。结论：这些研究结果强调了加蓬lambarsamnise多寄生虫感染的负担和不利的健康影响。
