Effect of intestinal helminth infection on some nutritional parameters among rural villagers in Nepal

We report the prevalence of intestinal helminthiasis and its impact on health of Nepalese in two different rural Village Development Committees (VDC) in Nepal. A total of 261 school children from Okharpauwa VDC in Nuwakot district (Central Region) and 242 inhabitants of Boya VDC in Bhojpur district (Eastern Region) in Nepal were included in this study. The overall prevalence in these two different districts were 57.5% and 55.4%, respectively. Altogether four types of helminths were detected. In both districts, Ascaris lumbricoides was the commonest helminth. Mixed helminth infection in both study areas accounted for less than 5.0%. All helminth infected subjects were treated with a single dose of albendazole. Heavy Trichuris trichiura infection needed a second dose. Blood hemoglobin and serum total protein level in school children in Okharpauwa VDC increased significantly after chemotherapy (P < 0.05). Eosinophil count (10.1%; SD 5.0325) returned to normal (4.8%; SD 4.6997). Helminth infection in Boya VDC was more common in children than in adults. Serum total protein, albumin, total cholesterol and triglycerides levels were not influenced by the presence or absence of helminths among the inhabitants of Boya VDC. In both districts, more than 80.0% of the household had no latrine. In Boya VDC, 94.0% of inhabitants interviewed were not aware of other intestinal parasite other than A. lumbricoides.
