Introduction: Cervical cancer is the fourth most common women cancer and thernfourth most common cause of cancer death worldwide. The high rate of cervicalrncancer among women have been reported from several African countries includingrnEthiopia. HIV positive women have a higher prevalence and incidence of cervicalrnprecancerous lesions than HIV negative women. In Ethiopia a little is known aboutrnHIV positive women knowledge, attitude and their screening practice about cervicalrncancer screening.rnObjective: To assess knowledge, attitude, practice about cervical cancer screeningrnand associated factors among HIV positive women attending public health institutionsrnin Bahirdar, Northwest EthiopiarnMethods: Facility based cross sectional study was conducted among a total of 477rnHIV positive women who attended public health institutions using a pre testedrnstructured questionnaire. The study participants were selected using SystematicrnRandom Sampling Technique. Descriptive statistics were used to summarize sociodemographicrncharacteristics of study participants. Logistic regression analysis wasrnfitted and odds ratios with 95% CI and P value were computed to identify effects ofrncovariates with participantsâ€™ knowledge, attitude and cervical cancer screeningrnpractice.rnResult: About 162(35.4%) of HIV positive women have had a good knowledgernabout cervical cancer and screening practice. More than half of the respondents had arnpositive attitude 298(65.1%) but only 14.2% [95% CI (0.11,0.17)] of the respondentsrnwere screened once in a lifetime. Educational status was the only variable to showrnsignificant association with knowledge. Marital status, education, and women withrnone sexual partner showed significant association with attitude. Knowledge andrnoccupation were significantly associated with the practice of cervical cancerrnscreening. Women with good knowledge of cervical cancer screening were 15 timesrnmore likely to seek cervical cancer screening [AOR=15.28; 95% CI (7.338,rn31.819)].rnConclusion: This study revealed that most of HIV positive women have poorrnknowledge about cervical cancer screening and very few were ever screened forrncervical cancer. Thus warrant to the concerned bodies for the creation of cervicalrncancer awareness campaigns and screening programs at all levels of the health sectorrnand encourage HIV positive women for cervical cancer screening.
