Determinant factors of pregnant mothers’ knowledge on mother to child transmission of HIV and its prevention in Gondar town, North West Ethiopia

BACKGROUND: Mother-to-child transmission of HIV is a very important mode of HIV transmission for children. Well-functioning and accessible health facility and knowledge on mother to child transmission of HIV are a prerequisite for a successful mother to child transmission prevention of HIV. However, the determinant factors of pregnant mothers’ knowledge towards mother to child transmission of HIV and its prevention is not well studied in Ethiopia and particularly in the present study area. METHODS: Cross-sectional health institution based study was conducted in Gondar town from July 22-August 18, 2011. A total of 400 pregnant women attending antenatal care (ANC) were involved in the study using stratified sampling technique. Data were collected by using structured questionnaire and multiple logistic regression analysis was used. RESULTS: A total of 400 pregnant women actively participated in this study and 354 (88.5%) of them knew mother to child transmission of HIV and 334(83.5%) of them knew mother to child transmission of HIV is preventable. Having knowledge on mother to child transmission of HIV was positively associated with attending antenatal care visits in hospitals [Adj. OR (95%CI) = 4.49 (1.003, 20.06)], residing in urban areas [Adj. OR (95%CI) = 2.46 (1.19, 5.09)] and having education level of secondary and above [Adj. OR (95%CI) = 6.85 (1.96, 24.01)], but negatively associated with increased maternal age. Knowledge on prevention of mother to child transmission of HIV was positively associated with accessibility of health facility [Adj. OR (95%CI) = 2.16 (1.03, 4.57)], having perceived risk of HIV [Adj. OR (95%CI) = 2.61 (1.32, 5.17)], having comprehensive knowledge on HIV [Adj. OR (95%CI) = 2.86 (1.41, 5.82)], having education level of secondary and above [Adj. OR (95%CI) = 6.15 (1.75, 21.66)] and residing in urban areas [Adj. OR (95%CI) = 3.62 (1.73, 7.59)] but negatively associated with increased maternal age. CONCLUSION: Most of the study participants in this study knew that HIV could be transmitted from an infected mother to her baby. There should be well functioning and accessible health facilities with Prevention of mother to child transmission service in the country especially in the rural areas.
