Abstract
ntestinal helminthic infections are still the neglected public health problems
worldwide. It represents a major cause of morbidity and mortality in high risk ethnic
groups of rural communities. The present study was conducted in Nisdi Rural
Municipality, Palpa Nepal. The cross sectional study was conducted and purposive
sampling method was applied to choose the study subjects. Two hundred and eighty
fresh stool samples of Magars including all age groups were collected and preserved
in 2.5 % potassium dichromate solution. Structured questionnaire method was
conducted for the identification of risk factors. The samples were examined
microscopically using direct wet mount and concentration methods to determine the
prevalence of intestinal helminthic parasites . The present study showed high rate of
intestinal helminth infection i.e 31.07% along with taeniasis 2.5% in Magar
Community of Nisdi Rural Municipality, Palpa. The most common intestinal helminth
parasites were hookworm (12.5%) followed by Ascaris lumbricoides (11.8%), Taenia
spp. (2.5%), Hymenolepis nana (1.7%), Trichuris trichiura (1.4%), Strongyloides
stercoralis (1.1%) and Enterobius vermicularis (1.1%).
Univariate logistic regression revealed that people practicing the walking and working
barefoot and occationally using the slippers or sandals (OR = 6.339, CI = 3.46311.591),

people having muddy
house (OR= 2.282 95% CI = 1.258 -4.136) and source of drinking water as reservoir
system (OR=1.716, 95% CI = 1.026-2.868) were the important risk factors for
intestinal helminth infections . Similarly, the two important risk factors associated with
taeniasis found in this community were not using latrine who preferred open defecation
(OR =5.285, CI =1.149-24,306) and consumption of uncooked pork meat (OR=12.828,
95% CI= 1.521-108.6). Females (OR=2.2, 95% CI=3.809 -1.276) are at high risk of
intestinal helminthic infections wheras males (OR =3.879, 95% CI=0.739-20.352) are
at high risk of infection for taeniasis. Occupationwise, farmers are at greater risk of
infection for both Intestinal helminth infection and taeniasis.
