Bivariate analyses were done in order to determine whether perceived factors by mother such as TV/Radio announcement, distance from home to ANC, ANC friendly services, socio cultural norms, mother being proactive, partner knowledge on PMTCT, willingness of a mother to be escorted to ANC and busy partner are associated with male partner involvement in Prevention of Mother to child transmission of HIV infection. Socio-demographic factors of both mother and partner such as marital status, partner being in same religion, polygamist partner and partner's level of education were also assessed. In the bivariate analysis, mothers who reported that their partners have been exposed to TV/Radio announcement addressing PMTCT had three times higher odds of their partners being involved in PMTCT than those who reported no such exposure (COR 2.9 CI 1.4-6.6). Likewise mothers who reported that their partner had knowledge on PMTCT had 20 times higher odds of their partners being involved in PMTCT than those who reported no such knowledge (COR 20.5 CI 5.8-72.8). Mothers who were asking for escort to ANC from their partners were having 38 times more chances for their partners to be involvement in PMTCT services than those were not asking for escort (COR 37.9 CI 11.0-130.6). In additional mothers who live together with their male partners are three times more likely to have their male partners involved in PMTCT services than those who don't live together (COR 3.2 CI 1.5-7.0) while mothers who are married have two fold more likely to have their partners involved in PMTCT services than those who are not married (COR 2.3 CI 1.2-4.6). Also mothers who reported to be in same religion with their partners had six times increased chances of male partner being involved in PMTCT services than those who were not in the same religion (COR 5.7 CI 1.7-19.0). On contrary, mothers who did not want to be escorted to ANC by their partners had 92% less likely to have their male partners involved in PMTCT services (COR 0.08 CI 0.01-0.6). Additionally mothers who reported their male partners to be busy with other daily activities especially on days of ANC had 62% less likely their male partners to be involved in PMTCT services (COR 0.38 CI 0.2-0.7). Furthermore socio-cultural norms and multiple marriages were limiting factors for male involvement in PMTCT [(COR 0.3 CI 0.1-0.9) and (COR 0.44 CI 0.2-0.9)]. Partners who had secondary education and above were 32% less likely to be involved in PMTCT services than those who had primary education and below however this association was not significant (Table 3). On logistic regression, proactive mothers who always ask for escort from their partners ranked the first as a promoting factor for male involvement in PMTCT services. Data show that mothers who always ask for escort from their partners had 28.6 times increased odds of their male partners being involved in PMTCT (AOR 28.6 CI 7.1-116). The second promoting factor for male involvement in PMTCT was perceived partner's knowledge on PMTCT. Data show that mothers who reported that their male partners being knowledgeable on PMTCT had 24.6 increased odds of their male partners being involvement in PMTCT than those mothers whose partners had no such knowledge (AOR 24.6 CI 5.9-102). Mothers whose partners had exposure to TV/Radio announcement addressing PMTCT had 4.6 times increased odds of their male partners being involved in PMTCT than those with no such exposure (AOR 4.6 CI 1.5-14.2) while married status of mother had 3.7 times more likely to have their male partners involved in PMTC (AOR 3.7 CI 1.5-9.4). On the other hand, Mothers who did not want to be escorted by their male partners were 93% less likely to have their male partners involved in PMTCT services than those who wanted escort (AOR 0.07 CI 0.01-0.7) while perceived busy partners were 54% less likely to be involved in PMTCT (AOR 0.46 CI 0.2-0.9). The rest factors which were significant on Bivariate analysis were not significant on logistic regression model (Table 3).
