Abstract

BackgroundIntestinal parasitic infections (IPIs) are still among the major public health issues in developing countries. Assessing the prevalence of IPIs and potential risk factors in different localities is essential to enhance control strategies. To date, no prevalence assessment study was conducted in Debre Berhan town. Therefore, the aim of this study was to assess the prevalence of IPIs and associated habit and culture-related risk factors among primary schoolchildren in Debre Berhan town, Northeast Ethiopia.MethodSchool based cross-sectional study was conducted from April to June 2017. A total of 645 children aged 6–15 years were selected from six primary schools in Debre Berhan town via a multistage random sampling technique. A structured questionnaire was used to collect data about sociodemographic and potential risk factor variables. Fresh stool samples were collected from each child and examined using direct smear and formal-ether concentration technique.ResultAmong the 645 children participated in the study, 341 (52.9%) were infected by one or more intestinal parasites. Helminths (33.8%) were more prevalent than protozoa (20%). Double parasitic infection rate was 0.9%. The predominant parasites were Ascaris lumbricoides (22.6%), Entamoeba histolytica/dispar/moshkovskii (18.1%) and Hymenolepis nana (5.7%). Multivariable logistic regression analysis showed that age of child (6–9 years), family size (above 5), mother’s illiteracy and primary education, father’s illiteracy, urban-farmer father, manual-worker father, not washing hands before eating, unclean fingers, open defecation site (ODS) near residence, latrine type, cultural response to dropped food (cleaning and eating; ‘kiss and replace’), habit of playing with waste water, habit of playing with soil, habit of sucking fingers and habit of eating when playing were significantly associated with IPIs (p< 0.05). Likewise, age (6–9 years), mother’s illiteracy, urban-farmer father, not washing hands before eating, ODS near residence, tradition of cleaning and eating dropped food, habit of playing with soil, sucking fingers and eating when playing were identified as significant risk factors of A. lumbricoides infection.ConclusionHigh prevalence of IPIs among the study participants demands improvement of environmental sanitation, personal hygiene, and health education regarding the potential habit and culture-related risk factors.

Highlights

  • Intestinal parasitic infections (IPIs) are still among the major public health issues in developing countries

  • Study design and study area School based cross-sectional study was conducted from April to June 2017 among primary schoolchildren in Debre Berhan town, Northeast Ethiopia

  • Father’s illiteracy, mother’s illiteracy and primary education were significantly associated with presence of IPIs in children, which was consistent with the results previously reported elsewhere [13, 24, 35]

Summary

Introduction

Intestinal parasitic infections (IPIs) are still among the major public health issues in developing countries. No prevalence assessment study was conducted in Debre Berhan town. The aim of this study was to assess the prevalence of IPIs and associated habit and culture-related risk factors among primary schoolchildren in Debre Berhan town, Northeast Ethiopia. The soil transmitted helminths (STHs) alone affect above 2.5 billion people worldwide [4]. Intestinal parasites are mainly transmitted via the fecal-oral route. The majority of these parasites are orally acquired, while some species such as hookworm and Strongyloides stercoralis infect by skin penetration [2, 6]
