Abstract:
Intestinal parasitic infections are one of the major public health problems in many developing
countries including Ethiopia. Sub-Saharan Africa is the most heavily burdened region by
intestinal parasites. The present study was carried out to determine the prevalence of
intestinal parasitic infections (IPIs) and their associations with anthropometric measurements
of children in selected primary schoolchildren in Kelela town, South Wollo, Ethiopia. The
design of the study was a cross-sectional epidemiological investigation involving a sample
population of 384 school children from grade one to grade eight in two purposively selected
primary schools located in Kelela town conducted from February to March, 2021. Socio demographic data from the study participants were gathered using structured questionnaire.
A total of 384 fresh stool samples of school-children were examined using subjected to direct
wet-mount technique and Formula-Ether concentration method and examined under
microscope. The overall prevalence of intestinal parasitic infections based on the presence of
any intestinal parasite species was 74.4% (76.5% in males and 72.9% in females). Multiple
infections with two and above parasites species based on the presence of any intestinal
parasite species were found 9.4% (36) of the positive stool samples. The prevalence of
intestinal protozoan parasites, Entamoebahistolytica, Giardialamblia was 24.5%, 15.9% and
respectively. Similarly,the prevalence of helminth infections, A.lumbricoides, Hookworm, T.
trichuria, S.mansoni, E.vermicularis, H.nana and Teania saginata. was 5.7%, 3.9%, 3.1%,
3.1%, 1.3%, 1% and 0.8%, respectively was 6.8%, 4.2%, 3.6%, 2.9%, 1%, 0.8% and 0.5%,
respectively. The prevalence of intestinal parasitic infections was significantly associated with
some of risk factors, such as family size, source of water and its handling, and availability of
latrines (p=0.001, p=0.004 and p=0.005, respectively). However, the prevalence of IPIs were
not statistically associated with some socio-demographic factors, such as parents’
educational level, personal hygiene, life skills, awareness to parasitic infections, residence
and wearing shoe or not. A significant association was found between prevalence of IPI
species based on the presence of any intestinal parasite species and underweighted students
(p=0.004) those school-children who were. Underweight had a higher prevalence of
IPIs(48.5%) as compared with other anthropometric indices (wasting and stunting). In
general, intestinal parasitic infections represent majr public health problem of children in the
study schools in kelela town. Local health officer and any other concerned bodies should
collaborate with the primary schools management to design and implement appropriate
prevention control measures to alleviate the negative effect of IPIs on the school children
