Intestinal infestations are of considerable public health importance in Zambia and elsewhere in Africa. Children aged less than 5 years are at the highest risk of infection. Interventions for prevention and control of these infestations require identification of their determinants. This study investigates the determinants of intestinal infestations in children below 5 years of age admitted to a children's hospital and assesses the most prevalent of the helminthes.
This was a hospital based cross-sectional study conducted at Arthur Davison Children's Hospital, Ndola, Zambia. Socio-demographic data of study participants and possible determinants for occurrence of intestinal infestations were collected using structured questionnaires. Stool samples were collected and examined for presence of parasites using direct techniques. The Pearson's Chi-square and Fisher's exact tests were used to establish associations.
Present study had 148 participants out of the expected 165, making a respondent rate of 89.7%. Over half of the participants were male (50.6%), and 68.9% were above the age of 2 years. Prevalence of intestinal infestations was 19.6%, and the most prevalent parasite was Ascaris lumbricoides. Factors independently associated with worm infestation were father's employment (AOR = 0.41; 95 % CI [0.19, 0.90]) and history of prior worm infestation (AOR = 6.54; 95 % CI [3.28, 13.03]).
Intestinal infestations particularly Ascaris lumbricoides were more prevalent in this study. There should be policy towards countrywide deworming programs and enhanced hygiene.
肠道寄生虫感染在赞比亚及非洲其他地区具有相当重要的公共卫生意义。5岁以下儿童感染风险最高。预防和控制这些感染的干预措施需要确定其决定因素。本研究调查了入住儿童医院的5岁以下儿童肠道寄生虫感染的决定因素,并评估了最常见的蠕虫。
这是一项在赞比亚恩多拉市亚瑟·戴维森儿童医院进行的基于医院的横断面研究。使用结构化问卷收集研究参与者的社会人口统计学数据以及肠道寄生虫感染发生的可能决定因素。收集粪便样本并使用直接技术检查是否存在寄生虫。采用Pearson卡方检验和Fisher精确检验来确定关联。
本研究预期有165名参与者,实际有148名,应答率为89.7%。超过一半的参与者为男性(50.6%),68.9%的参与者年龄在2岁以上。肠道寄生虫感染患病率为19.6%,最常见的寄生虫是蛔虫。与蠕虫感染独立相关的因素是父亲的就业情况(比值比=0.41;95%可信区间[0.19, 0.90])和既往蠕虫感染史(比值比=6.54;95%可信区间[3.28, 13.03])。
在本研究中,肠道寄生虫感染尤其是蛔虫感染更为普遍。应制定全国范围的驱虫计划政策并加强卫生措施。
