    (Addis Ababa Universty, 2011-05) Worku, Abebe; Negi, Rakshit (PhD)
    The primary purpose of this research study was to assess marketing system for the fi sh originated from Lake Tana. Additionall y, efforts have been made to describe the root causes of the problems facing va rious actors (Fishermen, distributors/retailers and consumers) in the fi sh marketing system, from production to marketing stage. In order to accomplish research objectives, two areas i.e. Lake Tana and Addis Ababa were considered, from production and marketing/selling perspectives, and looking after the operations performed by the three (above mentioned) actors of the fi sh marketing system. Therefore, data were collected from the fi shermen in Lake Tana, retailers (bringing the fi sh from the production area to the market), and consumers in the terminal market (Addis Ababa) specifically, Piazza, Bole and Merkato, being considered for the purpose of the study, in order to assess the performance of the system and by describing the practices and problems across the fi sh marketing system from the point of production ti ll consumption. A total of 225 respondents, constituting producers (31), retailers (56) and consumers (13 8) were se lected, by using cluster and convenient sampling techniques, to take part in the study. For the purpose of primary data collection, two self administered questionnaires were designed and distributed to the respondent retailers and consumers; however, the researcher administered another category of questionnaire developed for fi sh producers from the Lake Tana, by himself, as many of the participants were illiterate. The reported instruments were prepared both in English and the local language (Amharic), to be fill ed by the respondents in the language preferable to them. Once the data collection stage was over, collected responses were organized in the form of tables and graphs, by using percentage, average scores, standard deviations, and Chi-square analysis. Though, the interview data were interpreted into meaningful facts, highlighting the problems associated with poor performance of exchange and phys ical functions by the producers and retailers, lack of cooperation among fi shermen, and no access to timely information about the demand and price of fish in the market, on the paJ1 of fi shermen from Lake Tana. Altogether, these factors appeared to be making the fish originated from Lake Tana inferior in quality, expensive in comparison to the fi sh from other lakes, and unfair prices obtained by the producers.

    Prevalence of Helicobacter pylori and Intestinal Parasite and their Associated Risk Factors Among School Children at Selam Fire Elementary School in Akaki Kality, Addis Ababa, Ethiopia
    (Addis Ababa University, 2017-06) Worku, Abebe; Desta, Kassu (Assistant Professor)
    Background: The prevalence of H. pylori infection mainly acquired during childhood and may be persisting throughout life and it has been found high in developing countries; this prevalence is related to low socioeconomic status, and Intestinal parasitic infections are among the major public health problems in Sub-Saharan Africa. Their distribution is mainly associated with poor personal hygiene, environmental sanitation and limited access to clean water. There is limited information on the burden of the H. pylori and intestinal parasites in Ethiopia and this research will address such gap. Objectives: To assess the prevalence of Helicobacter pylori and intestinal parasite and their associated risk among Elementary School Children. Methods: A cross sectional study was conducted to determine the burden and risk factors associated of H. pylori and intestinal parasite among in 422 school children. The study was conducted between March to June 2017. Multiple sampling methods were used, to collect the data. The stool samples were tested for intestinal parasite using direct wet mount and concentration techniques and stool antigen test for H. pylori. Information from the laboratory analysis and questionnaires were entered into SPSS version.20 for analysis. Results: A total of (n=422) students have been participated in this study 55.2 %( n=233/422) 44.8% (n=189/418) were female and male respectively. Age of range (4-18) years, with mean age of 11.16±SD years [95% CI 10.82-11.5], the mean weight of 30.99 ± SD Kg [95 % CI 29.9 -32.08], the mean height 1.36 ± SD m [95% CI 1.34-1.38], Helicobacter pylori antigens were detected in 14.6% (n=61/422) ,and 6%(n=25/189) 8.6%(n=36/233) male and female respectively. Intestinal parasite were detected in 23.7 %( n=100/422), 10.4 %( n=44/189) 13.3 %( n=56/422) male and female respectively. The co-infection for HP and IPI was present in 4.5 %( n=19/422). The age of study subject, educational status/ monthly income status of their family/guardians, overcrowding and some sanitary practice were a risk factor for the development of intestinal parasite and H. pylori infection. Conclusions: The prevalence of H. pylori infection is 14.6 %, and IPI is 23.7 %, this burden of IPI among school children call mass de-worming which is going on in some schools. Moreover further studies are required to understand the role of HP and IPI on the overall growth of children and school performance.
