    Prevalence of intestinal parasitic infections, related risk factors and possible impact on nutritional status among private school children in Kathmandu
    (Department of Microbiology, 2016) Maharjan, Suman
    The present study was conducted among the primary level school children of four private schools of Kathmandu, Nepal to determine the prevalence of intestinal parasitic infections, possible pre-disposing factors as well as its impact on the nutritional status of the school children. This cross sectional study was conducted from July to November, 2014. A total of 329 stool and blood samples were collected and brought to the laboratory of Shi-Gan International College of Science and Technology (SICOST). Anthropometric data were collected and questionnaire related to their personal hygiene, socioeconomic condition were done. Stool samples were processed for microscopy by using formal-ether concentration technique. Hemoglobin was estimated by cyanmethemoglobin method. Statistical analysis was done by using SPSS 16.0. The overall prevalence of intestinal parasitic infection was 17.9% (59/329). Protozoan parasites were dominant (47.5%) over helminthes (22.0%). Altogether eight species of parasites were detected in the study. Giardia intestinalis (29.9%) was the most common protozoan parasite detected whereas Trichuris trichiura (24.7%) topped among the list of helminthes. The prevalence of intestinal parasitic infection was slightly higher among boys (18.6%) than girls (17.1%) (p=0.732). Similarly, the prevalence was significantly higher among the children belonging to age group 6-10 years (p=0.000). No statistically significant association was observed with respect to parents’ literacy, nail trimming, hand washing with soap before eating and after toilet, use of antihelminthic drug, source of drinking water and treatment of drinking water. A total of 41.0%, 29.0% and 11.0% children were found to be stunted, underweight and wasted respectively. Similarly, about 20.5% of the children were anemic without significant association between the parasitic infections. The results indicate the need of periodic deworming programmes, health education and improvement of sanitation and hygienic practices in private schools.
