Background: Disclosure of HIV status may lead to increased opportunities for socialrnsupport, to discuss and implement HIV risk reduction with partners and improved access torntreatment. Thus, status disclosure is major public health goal for HIV prevention &rntreatmentrnObjective: Determine the magnitude and determinants of HIV sero-status disclosure tornsexual partners among women people living with HIV/AIDS at Hawassa Referral Hospital,rnSNNPR.rnMethod: A Cross sectional survey was conducted among 384 HIV positive women whornhad sexual partner and age 18 years attending ART clinic from March to April 2008.rnUsing a structured and pre-tested questionnaire, data were collected through patientrninterview consecutively until the required number reached over one month period. Ethicalrnclearance from concerned bodies and informed consent from participants was obtained.rnX2 tests, odds ratios and logistic regression were done to explore associations betweenrndifferent variables and status disclosure.rnResult: Overall 85.7% the women had disclosed their HIV positive status to their sexualrnpartners. The common barriers reported for non disclosure of HIV status were fear ofrnabandonment; fear of break-up in relationship and fear of stigma. The negative partnerrnreaction reported by those women who disclosed to sexual partner in this study was foundrnto be high (59.3%). Majority (77.9%) had sexual intercourse in the past 6 month. 9.1% ofrnthe women were pregnant since they tested for HIV and condom was inconsistently usedrnby most of the women. Being married, taking ARV treatment for more than one year andrnknowing the HIV status of the sexual partner were predictors of HIV positive statusrndisclosure.rnConclusion: Even though, the magnitude of HIV positive status disclosure to sexualrnpartner in this study is encouraging, negative partner reactions following disclosure werernreported by large proportion of women. Follow up counselling, couple counselling andrntesting, integrating ART service to reproductive health service particularly F/P should bernemphasized in order to facilitate safe status disclosure and to address the sexual andrnreproductive health needs of PLWHAâ€™s.
