Background: Intestinal parasitic infections an important public health problem in developingrncountries. Low socioeconomic conditions, lack of access to potable drinking water, poorrnpersonal hygiene and environmental sanitation are the factors associated with intestinal parasiticrninfection.rnObjective: to determine the prevalence of intestinal parasitic infections and associated riskrnfactors in selected sub cities of Addis Ababa, Ethiopia.rnMethods: Community-based cross-sectional study was performed in Yeka and Arada sub citesrnof Addis Ababa from January to June 2019. A total of 382 study participants were selected byrnusing multistage sampling technique. From each participant, socio-demographic data wasrncollected by using standardized questionnaire and risk factors analyzed by using SPSS versionrn20 for analysis value less than 0.05 considered as statistical significant. In addition, stool samplesrnwere collected and analyzed by direct wet mount, formal ether concentration techniques and katorntechniques. Moreover, parasite load was estimated by using WHO criteria for degree ofrnparasitemia..rnResults: Out of the total 382 participants prevalence of intestinal parasites was 10.5%. Amongrnthese, Entamoeba histolytica/dispare(6.01%) was the most common, followed by Giardiarnlamblia (1.8%), Ascaris lubricoide (1%) ,Hookworm (0.8%) and Strongloid stercolaris (0.3 %).rnIn addition, 0.5% of positive cases were double infection, Entamoeba histolytica/dispare andrnGiardia lamblia. Intestinal parasitosis was seen more in female (5.75 %) than malern(4.18).According to WHO criteria the intensity of helminthic infection was light. Intestinalrnparasitic associated risk factors such failure to wash hands with soup before meal, a habit ofrneating undercooked vegetables had Statistical significant p value less than 0. 05.rn.Conclusion: The intensity of helminthic infection was light; this might be related to lowrnprevalence of intestinal parasitic infection. In addition, intestinal parasitic infection wasrnassociated with proposed risk factors. This indicates the need for additional preventive andrncontrol mechanism. Furthermore, large scale studies including assessment of environmentalrnsanitation, and healthy education need to undertake the problem.
