To assess the effect of sanitary provision and hygiene practices on intestinal helminth burden of primary school children.
The cross sectional descriptive study was undertaken in Egor Area of Benin City, Edo State, Nigeria. Using a calculated sample size of 384, participants were selected from primary schools in the study area, using a multi stage sampling method. Although, 384 pupils were expected to participate in the study only 365 provided faecal samples for examination giving a response rate of 95%.
In most of the schools surveyed, open refuse dumping, (score 1) was the prevalent practice. Portable water supply was present only in private schools within the compound, (score 4). Toilet facilities were grossly inadequate in number and without consideration for sex. Pit latrine, (score 2) was the common toilet provided in surveyed schools. Seventy seven, (21.1%) of the pupils were infected with one or more helminth ova. Pupils in public schools were more infected 72 (30.8%) than those in private schools 5 (3.8%). Helminth ova seen in examined faecal samples were A lumbricoides 61, (16.7%); followed by hookworm, 27 (7.4%); T. trichuria, 5(1.4%); S. stercoralis, 1(0.4%). Regular hand washing with soap reduced the prevalence of helminthiasis.
The level of sanitation observed in the schools studied was low. Consequently, more toilets, preferably the VIP type should be built to overcome the hazard of the pit latrine. Provision of portable water supply should be mandatory for all schools to ensure healthy learning environment.
评估卫生设施和卫生习惯对小学生肠道蠕虫感染负担的影响。
在尼日利亚江户州贝宁城埃戈尔地区开展了横断面描述性研究。采用多阶段抽样方法,从研究区域的小学中选取参与者,计算得出的样本量为384。尽管预计有384名学生参与研究,但只有365名提供了粪便样本用于检测,应答率为95%。
在大多数接受调查的学校中,露天倾倒垃圾(评分为1)是普遍的做法。只有校园内的私立学校有便携式供水(评分为4)。厕所设施数量严重不足,且未考虑性别因素。坑式厕所(评分为2)是被调查学校中常见的厕所类型。77名(21.1%)学生感染了一种或多种蠕虫虫卵。公立学校的学生感染率更高,为72名(30.8%),而私立学校为5名(3.8%)。在检测的粪便样本中发现的蠕虫虫卵有:蛔虫61例(16.7%);其次是钩虫27例(7.4%);鞭虫5例(1.4%);粪类圆线虫1例(0.4%)。经常用肥皂洗手可降低蠕虫病的患病率。
所研究学校的卫生水平较低。因此,应建造更多厕所,最好是VIP类型的,以克服坑式厕所的危害。应为所有学校强制提供便携式供水,以确保健康的学习环境。
