From the shadows: A qualitative study of fathers' perspectives and experiences of their partner's gestational diabetes mellitus and its implications

Gestational diabetes mellitus (GDM) affects an increasing number of women each year. Research involving partners of women with GDM, such as fathers is limited, however, understanding their perspectives and involvement in GDM management could enhance health outcomes for both women and their families. This study aims to explore the impact and experiences of GDM on fathers in the perinatal period. Qualitative, individual, semi-structured interviews were conducted with individuals whose partners either currently had GDM or had been diagnosed with GDM within the past 3 years. All participants identified as biological fathers. Data were transcribed and analysed using reflexive thematic analysis. Nine fathers participated in the study. Analysis resulted in four themes that explored fathers' experiences of GDM during the perinatal period: 'navigating a GDM diagnosis', 'partnering in management and health', 'finding a place within the GDM journey' and 'the lasting impact of GDM'. Fathers encountered wide-ranging impacts of their partners' GDM. Fathers provided both practical and emotional support to their partners. Engaging fathers in discussions at diagnosis and in management could facilitate the maintenance of positive health behaviour changes postpartum, potentially reducing the risk of type 2 diabetes for both parents.
