Background : Increasing access to family planning and reducing unintended pregnancies amongrnhuman immune deficiency virus (HIV) clients has a number of economic benefits, including lowrncosts for prevention of mother to child transmission (MTCT), lower costs for pediatric treatment andrnreduced costs for mitigating the consequences (such as low birth weights) of unintended births. Forrnwomen with HIV who do not wish to become pregnant, family planning is proven, cost effectivernstrategy for preventing vertical transmission of HIV. Yet there are limited studies conducted in healthrncenters to assess contraceptive use and factors affecting its use among HIV positive women.rnObjective: To determine magnitude of contraceptive utilization and associated factors among HIVrnpositive women that are enrolled for HIV care in government health centers in Addis Ababa.rnMethods: A facility based cross-sectional study was carried out on a sample of 682 HIV positivernwomen in the anti retroviral treatment (ART) follow up units of selected health centers in AddisrnAbaba. A systematic random sampling procedure was applied to select study participants. Data wasrncollected through interview using structured questionnaires. Data was analyzed using SPSS versionrn20.Multiple logistic regression analysis was done to see the association between the outcome andrnpredictor variablesrnResult: The magnitude of contraceptive use among sexually active study participant were 88.27%.rnThe most commonly used method was injectable followed by implant. HIV positive women who hadrna higher chance of contraceptive use were those who have two children (Adjusted odd ratio (AOR):rn2. 8; 95% CI: 1.2-6.3),those who have more than one sexual partner (AOR: 12.0; 95% CI: 3. 3-rn44.4)and those who disclose their status to their partner(AOR: 3. 4 95% CI: 1.52-7.55); Whereasrnwomen who were Protestant (AOR: 0.403; 95% CI: .191-.852),not currently married (separatedrn/divorced/widowed) (AOR: 0.221 95% CI: .097-.501)were less likely to use contraceptive.rnConclusion and Recommendation: The study has shown that about two-thirds of participatingrnHIV positive women use at list one contraceptive method. The most preferable contraceptivernmethods used were Injectables and implants. Among the long-term contraceptive methods, intrarnuterine contraceptive device (IUCD) were used in very low rate. Religion, marital status, number ofrnliving children, number of sexual partner and disclosure of HIV status to sexual partners were foundrnto be related with current contraceptive use among study population. We would like to recommendrnthat the regional health bureau has to work hard to increase coverage of contraceptive utilization byrnHIV positive women in order to prevent mother-to- child-transmission of HIV by strengthen thernexisting family planning services integration with ART clinics and particular emphasis should berngiven on encouraging women to disclose their HIV status to partners.
