BackgroundDiabetes in pregnancy is associated with short and long-term adverse health outcomes for mothers and babies. The condition disproportionately impacts Pacific, Maaori, and Indian pregnancies. Those with diabetes are offered intensive support during pregnancy, but in many centres, no additional support following birth beyond routine care. The aim of this study was to determine the postpartum needs for mothers and whaanau (family) impacted by diabetes in pregnancy, to inform co-design of a new service to improve metabolic and developmental outcomes for infants.MethodsPregnancies complicated by diabetes were identified using a local diabetes registry. Mothers with a diagnosis of GDM or T2DM and gave birth between January 2022 -June 2022 were eligible for the study. A total of 19 parents (18 mothers, 1 father) were interviewed. Participants primarily identified as Maaori (6), Pacific (6), Indian (3), Asian (2), and New Zealand European (2). Interviews took place between December 2022 and February 2023, between 5-13 months post-pregnancy. Interviews facilitated by an externally contracted local Pacific mother, with a professional background in social work were conducted using Koorero and Talanoa, Maaori and Pacific methods of qualitative data collection, to capture the lived experiences of participants. A multidisciplinary group reviewed and coded interview transcripts. Themes were presented back to participants and stakeholders for feedback and refinement. Four over-arching themes were illustrated with exemplar quotes.ResultsFour themes described the importance of 1) Finding a balance between what is “best practice” and what is best for me, my baby and my whaanau, 2) The need for individualised and culturally appropriate care, 3) Centrality of whaanau and family to the pregnancy and postpartum journey, 4) The pervasive negative impact of diabetes on taha hinegaro (well-being) beyond childbirth.ConclusionPeople who are affected by diabetes in pregnancy have ongoing physical, psychological, and social needs. A holistic, whaanau-centred approach is required to ensure optimal health and well-being outcomes of mothers, infants and whaanau. The findings of this study will inform a new targeted model of care for infants and whaanau affected by diabetes in pregnancy.
