HIV and AIDS continue to be a major public health problem where almost 70 million people have been infected with the Human Immune deficiency Virus and about 35 million people have died of AIDS since the beginning of the epidemic [1]. Globally, there are 3.3 million children under fifteen years living with HIV infection whose 95% of them acquired the infection through Mother to Child Transmission (MTCT) [2]. Without intervention the rate of MTCT cumulatively from pregnancy to cessation of breastfeeding ranges from 25 to 48% [2-4]. Prevention of Mother To Child Transmission (PMTCT) program focuses on HIV pre and post test counseling, feeding option and use of Highly Active antiretroviral Therapy (HAART) during pregnancy, intrapartum and postpartum. Studies has shown that use of Anti Retro Viral drugs (ARV) can significantly reduce MTCT of HIV to less than 2% [5]. The 2012 WHO guideline recommends that countries with limited laboratory and infrastructure capacity to provide universal access to CD4 cell count testing, all confirmed HIV-infected pregnant and breastfeeding women must be offered life¬long triple ART as soon as diagnosed regardless of their CD4 count or clinical stage as part of the new Option B+ [6]. Success in preventing MTCT will not only depend on use of antiretroviral prophylaxis, but also on continuing support to the nursing mothers from their male partners. It has been shown that male partner involvement reduces the risk of vertical transmission and infant mortality by 40% compared to non-involvement [7]. Mechanism by which male involvement contributes to the effectiveness of PMTCT include male socio cultural superiority and influence in many of the Africa settings [8]. Women learn and retain more information when educated together with their partners [9] and some pregnant mothers don't accept HIV testing till they have their partners consent or assent [10]. Indeed utilization of PMTCT services by pregnant women is affected by several factors such as fear of disclosure of HIV results, lack of male partner support, fear of violence, abandonment and stigmatization which all involve a male partner. Male involvement facilitates both ART initiation and adherence [11,12], it increases the probability of mothers delivering at health facility [13] and it enables for a good choice of breastfeeding plan [14-16]. This study aimed in determining magnitude, predictors as perceived by pregnant mothers and effects of male partner involvement in PMTCT services.

 

 

This was hospital based cross sectional study involving HIV positive pregnant women in Mwanza urban conducted from October 2013 through January 2014. Mwanza urban has a population of 706,453 people where 237,478 are women in reproductive age group of 15 to 49 years [17,18]. PMTCT services in the region started in 2004 at Nyamagana hospital and currently there are 45 health facilities which provide PMTCT services in the region. Ten out of 45 Health facilities in Mwanza urban were selected by simple random sampling using lottery method. Proportional to size sampling technique was used to obtain the number of study participants from each participating health facility (The size of each facility was the number of PMTCT attendees as per quarter of July-September 2013). We calculated the sample size based on the estimation of male involvement (defined as men who tested for HIV with their spouse at ANC) in the population of 21% [19], an absolute precision of 6%, design effect of 1.5 [17] and a 5% level of significance. We adjusted the sample size by considering 10% of anticipated non response. Therefore the total sample size was estimated at 300 HIV positive pregnant women. All pregnant mothers with at least 18 years who tested for HIV and agreed to be enrolled into PMTCT program were included. A pregnant mother in first or second trimester or if her partner is not alive was excluded from the study. Eligible clients from each Health facility who attended on days of interview were enrolled sequentially into the study. A face to face interview was conducted using a pre tested, semi structured questionnaire to collect information on socio demographic information both for participants and their male partners, partner testing and providing support to the mother and Factors affecting male participation in various PMTCT services as perceived by the mothers. Information on mother disclosure of HIV test result to her partner and any negative consequences after disclosure was also obtained.

 

Data were entered, cleaned, analyzed using Epi info version 3.5.4. Male partner involvement was a composite measure that included partner testing for HIV, partner support and partner aware of Mother's PMTCT status. Partner aware of mother's HIV status (disclosure) was further evaluated for existence of any form of Gender Based Violence. All independent variables including partner's knowledge were factors perceived by the mother as the respondent. Marital status such cohabiting and married were codes as living together while single and divorce were coded as not living together. Further coding for marital status was married for married couple while cohabiting, divorce and single were coded as not married. Univariate and Bivariate were done. Odds Ratio (OR) was used to quantify the likelihood of Male partner involvement into PMTCT and statistical significance was assessed using P- value and 95% confidence intervals for the odds ratios (OR). All independent variables with P-value <0.2 in the Bivariate analysis were considered for multivariate analysis through logistic regression to assess the effect of each covariate in the final model. Step down procedure for logistic regression was used to identify variables associated with male partner involvement in the final model. Ethical clearance was obtained from the Research Ethics Committee of Muhimbili University of Health and Allied Sciences. At the local level permission was also sought from Mwanza region authority and the respective health facilities authority. A written consent was obtained from each participant before interview.

 

 

Socio demographic information

 

A total of 300 HIV positive pregnant mothers were interviewed in this study. The mean age of the respondents was 27.5 years with standard deviation of 5.57 years. Majority, 211 (70.3%) of these mothers were married. Median gravidity was three with Inter-quartile range (IQR) of two and four while the median number of living children was two with IQR of one and three. The illiterate rate among study participants was more than 10% (Table 1).

 

Level of male partner involvement into PMTCT services

 

The level of male partner involvement in PMTCT was assesed using a series of questions as indicated in Table 2. Out of 300 participants, only 112 (37%) mothers had shared their HIV status with their partners. Partner`s HIV testing level was 114 (38%) of mothers reported their partners to have tested. A total of 96 (32%) mothers reported to have ever received support from their partners during the index pregnancy. The overall male partner involvement in PMTCT services (include men who scored yes in all the three questions) was 24.7% (74).

 

Magnitude of gender based violence

 

Of the 112(37%) mothers who reported to have shared their HIV serostatus with their male partners 18 (16.1%) reported different types of gender abuse. A substantial proportion (39%) of women who experienced gender based violence reported that their partners decided to stay away from them (separation) and 11% stated that they were beaten before their partners went to live away. Beating alone was the second most common form of abuse (Figure 1).

 

Predictors of male involvement in PMTCT services

 

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).

 

Effect of male partner involvement on domestic partner violence

 

In this study we aimed also at determining the effect of male partner involvement on reported gender based violence. There is a great association of reported gender based violence and male partner involvement as data show that those mothers whose partners are involved into PMTCT are 98% less likely to be involved in violence than those whose partners are not involved into PMTCT (Crude OR 0.02 P < 0.001) (Table 4).

 

 

This study was able to determine magnitude of male partner involvement into PMTCT services as well as identifying factors affecting male partner involvement into PMTCT services as perceived by mothers. Furthermore it has demonstrated that male partner involvement has a significant influence on preventing Gender based violence. The magnitude of male partner involvement shown in this study was 24.7%. This findings correlates with that reported by Byamugisha et all in Uganda where 26% of men whose wives were attending ANC at Mbale Regional Referral hospital reported to have full male involvement [20]. Likewise, the magnitude of male involvement in this study is more or less the same as that reported in the bottleneck analysis report of Tanzania e-MTCT of 2012 which showed only 21% male partner involvement [21], this slight difference might be attributed to under reporting of the routine data used to compile the bottleneck report. However due to differences in definition of male involvement and setting of the study, the magnitude in this study is much higher from 12.5% which was reported by Msuya SE et al in Moshi urban [22]. Studies done in Cameroon, South Africa and Malawi have reported male involvement of less than 20% [23-25]. In the same way as found by Kilewo C. et al in 2001 among women participating in a perinatal trial in Dar es salaam, less than 20% of them had shared their HIV results with their partners eighteen months after diagnosis [26]. This correlates with the findings of this study where the proportion of HIV positive pregnant mothers who have shared their serostatus to their partners was 37%. This could be contributed by low (38%) HIV testing level of male partners as noted also by Falnes EF et al 2010 in northern Tanzania [27]. Tadesse E et al 2004 in Blantyre Malawi found also that women have great trust to their male partners if and only if they are tested for HIV because majority of them choose their partner as their primary confidants after they tested for HIV [28].

 

In this study, it has been shown that women have a great role to play in making their male partners involved into PMTCT. Data show that proactive mothers who always ask their partners for escort to ANC are mostly associated with positive impact on male partner involvement. The studies done by Fisaha H et al 2012 in Makelle, Nothern Ethiopia on male partner involvement in PMTCT also found that maternal willingness to inform their husband about availability of testing services at ANC was an independent predictor for male partner involvement [29]. As expected, male partners who are knowledgeable on PMTCT are more likely to adopt PMTCT services. Data in this study reveals that male partners who are knowledgeable on PMTCT are 24 fold more likely to be involved into PMTCT than those who have no knowledge about PMTCT. Many studies have found that lacking PMTCT knowledge among male partners is a major hindrance to their male involvement [29,30]. Furthermore, this study shows that TV/Radio broadcasts play a major role in encouraging men for PMTCT involvement. This is likely the main source of educating and promoting knowledge of PMTCT in the society. On the other hand factors such as socio cultural norms, polygamist partner, and perceived ANC distance which have been shown by other studies as determinants of male involvement in PMTCT [23, 31,32] were not found to be significant in this study. This is likely to be due to changes in taboos favored by technological advancement in information sharing. Many people in urban area own TV, Radio and phones which have access to various communication media such as facebook, whats up, twitter to mention a few. People can acquire knew knowledge easily and fast, and this facilitates changes in taboos. Factors like friendly ANC services and partner fearing of HIV test result were inconclusively significant because of having empty numbers in some of the shells. This could require more exploration with large sample size. Male partner involvement into PMTCT services in its real definition as defined by a researcher has a negative impact on Gender Based Violence. In this study, male involvement was associated with reduced odds of GBV by 98%. Likewise, a study done by Semrau K et al in 2005 reported that couple counselling makes a man more responsible for the health of the partner and the family resulting to less blame and discrimination [33]. This indicates that counselling and HIV status disclosure resulting from male involvement reduce the probability for a male to engage in violence.

 

Despite that to a large extent this study has been able to answer intended research questions also it has some limitations. First in this study male information was extracted using female partner. A use of this approach in one way or another might affect the result in this study because female partner is more likely to have recall bias however the findings of this study correlate with other studies which interviewed men [20,30]. Second the possibility of desirability bias is also expected because mothers attending PMTCT services are trained on PMTCT hence they tend to answer what they think is expected from them. Thirdly, the cross section nature of this study will not prove if the associated factors of male involvement are actually causal. However, most factors identified are also supported by robust studies done elsewhere. Fourth, we anticipated that the use of pre-prepare structure questionnaire may results into information bias, to minimizes this all interviewers were oriented to the meaning and intention of every question before beginning the study. Finally this study was done into a single selected region in Tanzania this might limit generalizability of its findings.

 

 

This study was set out to demonstrate the magnitude of male partner involvement and measure the strength of association with the determinants. Male partner involvement into PMTCT services in Mwanza urban is low. Proactive mothers on asking escort from their partners is the mostly associated promoting factor of male involvement followed by partners' knowledge on PMTCT then hearing TV/Radio announcements addressing PMTCT. Unwillingness of a mother to be escorted by partner is the major hindrance of male involvement into PMTCT services. Male partner involvement is likely to reduce events of gender based violence. TV/Radio announcements addressing PMTCT need to be advocated so as to increase exposure to every man. Likewise women have a role to play in making their men participate in PMTCT activities.
