FACTORS ASSOCIATED WITH THE PREVALENCE OF ASCARIS LUMBRICOIDES INFECTION AMONG PRESCHOOL CHILDREN IN A PLANTATIONzzm321990COMMUNITY, KANDY DISTRICT, SRI LANKA.

Plantation living conditions in Sri Lanka are often poor. Ascaris lumbricoides infections are common among those living in plantations. We conducted a cross sectional study of children aged 1 - 6 years living on a plantation to determine the prevalence of ascariasis and factors associated with it in order to educate on prevention and to implement treatment programs. A total of 258 preschool children selected using a simple random sampling was included in the study conducted during January - April, 2013. Data regarding socio-demographic and hygienic habits were collected from heads of households via an interviewer administered structured questionnaire. Wet mount preparation, formaldehyde-ether sedimentation and Kato-Katz techniques were used to evaluate stool samples for Ascaris eggs. The overall prevalence of Ascaris infection among study subjects was 37.8%. On multivariate logistic regression analysis, factors significantly associated with Ascaris infections were: living in attached houses (p=0.035), shared toilet facilities (p=0.001), de-worming period more than three months (p<0.001), maternal education level (p<0.001) and living in the “Top” government administrative division (p=0.028) in the study area. Poor sanitation facilities and poor health education were important factors associated with Ascaris infections. A health education program promoting improved sanitary facilities and good hygiene is needed to reduce the prevalence of Ascaris infection in the study population.
