Data was obtained from all study subjects and blood and fecal specimen were collected from all subjects who apparently volunteer to take part in the study.
To determine prevalence of hookworm infection and its association with anemia. METHODS.: A cross-sectional study was conducted from February to April 2007 in Diga District, East Wollega Zone. Hematocrit test was done on all blood samples. All stool specimens were processed with a Kato-thick method and examined for parasites and the density of parasites was determined as eggs per gram of stool (epg). Frequencies and proportions were used for the descriptive analysis of the data and Pearson Chi-square test was used to assess the associations between the demographic characteristics of the study subjects and the findings of the test samples.
The overall prevalence of intestinal parasites was 64.9% Hookworm was the predominant (49.7%) intestinal parasite identified among the study participants. The density of hookworm egg ranged from 48 epg to 11,520 epg with mean and median values of 685 and 288 epg respectively. The observed result for hematocrit ranged from 12% to 50% with mean (SD) and median values of 34.6% (4.7) and 36% respectively. The prevalence of anemia is 65.5% among study participants. Among those subjects with hookworm, 83.9% were anemic. On the contrary only 41 (22.5%) study subjects who appeared negative for hookworm on stool examination were anemic.
The prevalence of hookworm is higher and it is associated with anemia in East Wollega zone. Therefore intervention strategies should consider the concomitance of hookworm and anemia in the implementations of appropriate prevention and control strategies.
从所有研究对象处获取数据,并从所有明显自愿参与该研究的对象中采集血液和粪便样本。
确定钩虫感染的患病率及其与贫血的关联。方法:2007年2月至4月在东沃莱加区迪加县进行了一项横断面研究。对所有血液样本进行血细胞比容检测。所有粪便样本采用加藤厚涂片法处理,检查寄生虫,并将寄生虫密度确定为每克粪便中的虫卵数(epg)。频率和比例用于数据的描述性分析,Pearson卡方检验用于评估研究对象的人口统计学特征与检测样本结果之间的关联。
肠道寄生虫的总体患病率为64.9%。钩虫是研究参与者中最主要的(49.7%)肠道寄生虫。钩虫卵密度范围为48 epg至11520 epg,平均值和中位数分别为685 epg和288 epg。血细胞比容的观察结果范围为12%至50%,平均值(标准差)和中位数分别为34.6%(4.7)和36%。研究参与者中贫血的患病率为65.5%。在那些感染钩虫的受试者中,83.9%患有贫血。相反,在粪便检查中钩虫呈阴性的研究对象中,只有41人(22.5%)患有贫血。
东沃莱加区钩虫患病率较高,且与贫血有关。因此,在实施适当的预防和控制策略时,干预措施应考虑钩虫与贫血并存的情况。
