Intestinal parasitic infections are major health problems in many developing countries, particularly
among pre-school and school-aged children. The current study aimed to determine the prevalence
and associated risk factors of intestinal parasitic infections among primary and junior school
students in Atsedemariyam town. A cross-sectional school-based study was conducted from
February to june, 2022. A total of 403 school students were involved in the study, and study subjects
were selected by stratified random sampling techniques with lottery method. A structured
questionnaire and direct observation were used to obtain relevant information on risk factors
associated with intestinal parasitic infections, and stool specimens were collected and examined
using wet mount and sedimentation techniques. Chi-square and logistic regression analysis were
used to assess the possible association between dependent and independent variables. The overall
prevalence of intestinal parasites in the current study was 35.7%, and eight species of intestinal
parasites were identified. Entamoeba histolytica/dispar was the predominant species at 10.4%
(42/403), followed by Ascaris lumbricoides 8.4% (34/403), hookworm 7.2% (29/403), Giardia
lamblia 6.2% (25/403), Taenia spp 2.7% (11/403), Trichuris trichiuria 2.7%(11/403), where as
Schistosoma mansoni 1.24% (5/403), and Enterobius vermicularis 0.5% (2/403) were rare or minor
case. In this study, The result of multivariate analysis revealed that the odds of being infected with
intestinal parasites were high among student whose age categories were 7-10 years (AOR=26.8,
95%CI=1.8-408.8,P=0.018) compared to whose age greater than 16 years. Students who did not
cleaning and cutting your finger nails (AOR =8.6 , 95% CI =1.8-41.4 ,P=0.007) compared to good
finger nail hygiene were strong predictors of intestinal parasitic infections among primary and
junior school students. Therefore, all concerned bodies should design practical action plans for
effective prevention and control of IPIs in the study area. In general creating awareness on IPIs
among school children and their parents in particular should be needed |
