Soil-Transmitted Helminths in Kindergarten Children: Prevalence, Intensity and Associated Factors in Bule Hora Town

Background: Soil-transmitted helminth (STH) infections are a common problem in Ethiopia. This parasite affects the physical and mental development of children, causing malnutrition and iron deficiency anaemia. However, there are inadequate studies that demonstrate the extent of STHs and associated factors among kindergarten children in South Ethiopia, particularly in the study area. Objective: The aim of this study is to determine the prevalence, intensity, and associated factors of STH infection among kindergarten students in Bule Hora town. Methods: An institution-based cross-sectional study was conducted among randomly selected 235 kindergarten children in Bule Hora town from January to February 2023. A pretested questionnaire was used to collect information on associated factors. EpiData and SPSS were used for data entry and analysis, respectively. Binary logistic regression analyses were performed to identify risk factors. Results: In the present study, the prevalence of STH was 28.5% (95% CI: 22.7%-34.3%). A. lumbricoides 26 (11.1%) was the most common parasite identified. The arithmetic mean (+SD) of the egg counts for each species of STHs was as follows: A. Lumbricoides 1886.9 (+2103.2), T. Trichiura 299.2 (+305.8), and hookworms 756.1 (+739.4). Factors that showed significant association in the current study were hand washing after the toilet (AOR: 2.992, 95% CI: 1.299-6.891,), fingernail trimming (AOR: 3.646, 95% CI: 1.704-7.798,), and shoe wearing habit (AOR: 2.143, 95% CI: 1.170-3.924,). Conclusion: STH infection is a health problem among kindergarten children in Bule Hora town. Comprehensive health education on the value of hygienic habits, improved sanitation, and routine deworming of kindergarten children should be included in prevention and control efforts.
