The putpose of this study was to investigate holY adult workers perceive their risk of HIVrninfection in relation to their sexual behavior in a setting of high HIV prevalence. To this end, arndescriptive survey method was employed. The study employed both primmy and secondaryrndata sources. The primmy sources of data were adult workers employed in Nazareth TractorrnAssembling Factory. Three principal data collecting tools were employed, namely,rnquestionnaire ,semi- structured interview and focus group discussion to access first hand data.rnThe secondmy source of data were generated from pertinent government policy and strategicrndocuments and also from literatures developed both nationally and internationally byrnprominent figures and institutions. A total of 170 adult workers in Nazareth TractorrnAssembling FactolY, were used as respondents. Purposive sampling technique was used tornselect the interviewees and random sampling technique was used to select FGD respondents ..rnData analysis was conducted using both descriptive and inferential statistics. In addition, bivariaternanalysis with Chi-square test was employed to see the relationship of the independentrnvariables with the dependent variable. As a result the following major findings were obtained:rn59.8% of the respondents knew that HIV is a virus, 21.3% have undergone VCT to know theirrnstatus, 17.3% have ever used condom, more than 70% have involved in multiple sexualrnpractices, and about 53.3% leveled themselves as higher risk perceivers due to variousfactorsrnassociated to their sexual behaviors. In addition, the bi-variate analysis has shown thernexistence of strong relationship between some of the independent variables (sex, VCT, alcoholrnconsumption and multiple sexual partners) and dependent variable (risk perception ofrnHIV/AIDS among adult populations). Based on major findings, conclusions were drawn andrnrecommendations were forwarded somc of these include;: Sound and viable information,rneducation and communication (lEC) and/or behavioral change communication (BCC)rninterventions should be initiated and jilrther strengthened by Nazareth Tractor AssemblingrnFactOlY Management; VCT for H IV should be encouraged by productive sectors andrnsupported by workplace specific jimctional HIV policy and the intervention in the world ofrnwork should necessarily consider adult education to impart an integrated and holisticrnknowledge; Concerted efforts of all the factOlY community are critically important to mitigaternthe spread and devastating impact of HIV/AIDS.
