摘要

这项研究旨在测量玻利维亚高原(高原)和低地(亚热带)农村地区学龄儿童中蠕虫和原生动物感染的发生频率,以及营养不良和贫血的风险因素,这些地区是胃肠道寄生虫感染的高发区。我们收集了 790 名 5-13 岁儿童的横断面数据。使用里奇技术对粪便进行了显微镜检查,使用 HemoCue 分析仪对血红蛋白进行了检测,并进行了人体测量。超过 60% 和 20% 的儿童分别感染了原生动物和蠕虫寄生虫。由致病性海门螺杆菌(15.7%-5.2%)、蛔虫(41.9%-28.5%)、贾第鞭毛虫(30.1%-11.2%)、组织溶解恩塔米巴虫(5.7%-0.7%)和非致病性大肠杆菌(48.与低地相比,高地的寄生虫感染率更高。单种寄生虫感染在低地更为普遍,而轻度或重度的多寄生虫感染在高地则占主导地位。在高原地区,儿童贫血的风险大大增加,而消瘦的发病率较低。年龄较大的儿童发育迟缓的风险较高,而肠道蠕虫的低负担可防止高地儿童消瘦。年龄较大的儿童感染疟原虫和羊角疯病原体并不是导致发育迟缓的重要协变量。环境、营养和寄生虫因素可能导致高地儿童贫血。营养干预和寄生虫控制工作将大大改善高原地区儿童的健康状况。

Frequency of Gastrointestinal Parasites, Anemia, and Nutritional Status among Children from Different Geographical Regions of Bolivia
The study aimed to measure the frequency of occurrence of infections with helminths, protozoa, and risk factors of undernutrition and anemia among schoolchildren from the Bolivian highland (altiplano) and lowland (subtropical) rural regions, with a high frequency of gastrointestinal parasite infections. Cross-sectional data were collected from 790 children, 5–13 years old. Microscopic examination of stool using the Ritchie technique, hemoglobin testing using the HemoCue analyzer, and anthropometric measurements were performed. Over 60% and 20% of children were infected with protozoa and helminth parasites, respectively. Infections caused by pathogenic Hymenolepis nana (15.7–5.2%), Ascaris lumbricoides (41.9–28.5%), Giardia lamblia (30.1–11.2%), Entamoeba histolytica (5.7–0.7%), and nonpathogenic Entamoeba coli (48.9–16%), Blastocystis hominis (40.2–28.5%), Iodamoeba butschli (16.1–2.5%), Chilomastix mesnili (19.2–7.3%), and Entamoeba histolytica/dispar (7.4–5.5%) parasites, were more prevalent in the highlands than the lowlands. Single parasitic infections were more prevalent in the lowlands; polyparasitism of light or heavy intensity predominated in the highlands. A strongly increased risk of anemia and a low prevalence of wasting were determined in children in the highlands. A higher risk for stunting was associated with children of older age, and a low burden of intestinal helminths would prevent wasting in children of highlands. Infections with A. lumbricoides and G. lamblia pathogens in older children were not significant covariates for stunting. Environmental, nutritional, and parasitic factors may predispose to anemia in the highlands. A nutritional intervention and parasite control effort will substantially improve children´s health in the highlands.

期刊介绍: Journal of Tropical Medicine is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies on all aspects of tropical diseases. Articles on the pathology, diagnosis, and treatment of tropical diseases, parasites and their hosts, epidemiology, and public health issues will be considered. Journal of Tropical Medicine aims to facilitate the communication of advances addressing global health and mortality relating to tropical diseases.
