BackgroundMen have traditionally not been fully involved in reproductive health care of their partners, and yet, they play a crucial role in family decision-making and therefore crucial key players in preventing poor pregnancy outcomes. This study aimed to assess prevalence and determinants of male participation in maternal health care and explore male partners’ perspective of their involvement in antenatal care at an urban tertiary referral facility.MethodsA mixed-methods study was conducted from October 2018 to January 2019 at Muhimbili National Hospital. A cross-sectional survey of 428 nursing mothers and two focus group discussions of male partners (n = 7 and n = 11) of women attending antenatal clinic and nursing mothers in the post-natal ward were performed. Using SPSS Ver. 23 (IBM, Chicago, IL), frequency distribution tables summarized demographic data and categories of male partners’ involvement in antenatal care. Focus group discussions included male partners of age from 24 to 55 years at their first to fifth experience of pregnancy and childbirth. Interviews were audio-recorded, and then transcribed and coded. Thematic analysis was applied.ResultsThe prevalence of male involvement in antenatal care was 69%. More than two-thirds of nursing mothers received physical, psychological and financial support from partners (76%) and attended four or more antenatal visits (85%). Five themes of male perspective of their involvement in antenatal care were generated, including: a) cultural norms and gender roles, b) ignorance of reproductive health service, c) factors outside their control, d) couple interaction and conflicts, and e) institutional obstacles.ConclusionThe prevalence of male partners’ involvement in antenatal care was relatively high. Men’s involvement in antenatal care depended on access to antenatal care education, standards of structure and process of antenatal service and how well their role was defined in the maternal health care system. Interactions and practice in society, employment sector and government health system should complement strategies to promote men’s involvement in maternal health.
