Gender variations in the prevalence of parasitic infections and the level of awareness in adolescents in rural Nepal.

ABSTRACT

The study was conducted in rural school adolescent children to investigate the awareness and its association in parasitic infections in boys and girls. Of the 182 children examined 119 (65.3%) were male and 63 (34.6%) were female, age ranged 12-20 years with median age 15 years. Out of 182 stool samples examined 73 (40%) were found to be positive for parasites in which two or more parasites were found in 10 stool samples. Giardia lamblia 33 (18.1%) was the predominant parasite followed by hook worm 27 (14.8%) Entamoeba histolytica 13 (7.1%), Ascaris lumbricoides 05 (2.7%), Hyminolepis nana 02 (2.2%) and Trichuris trichiuria 01 (0.5%). Thirty-one (49.2%) in 63 females and 40 (33.6%) of the 119 males were positive for parasitic infections. The prevalence of worm infection was significantly higher in female children than male (p < or = 0.05). In contrast to the high parasitic prevalence rate in females they possessed significantly higher levels of awareness about parasitic infections. Out of 119 males 99 (83.2%) and 61 (96.8%) of the 63 females (p < or = 0.05) knew that worms suck food from host body. Similarly, 62.2% of males and 96.85 of females (p < or = 0.05) knew that parasites suck blood from human body. More study should be carried out to find out the gender difference in parasitic infection and level of exposure to risk factors.
