AbstractBackgroundGestational diabetes mellitus (GDM) is experienced at a higher rate in women from culturally and linguistically diverse (CALD) backgrounds. The aim of this systematic review is to describe the experiences of women with GDM from CALD backgrounds and compare their experiences to women with GDM from non‐CALD backgrounds.Materials and MethodsMEDLINE, EMBASE, PsycINFO, Scopus, WOS and CINAHL databases were searched for qualitative and quantitative studies which included data on the experiences of CALD background women with GDM during all stages of pregnancy. Quality appraisal utilized checklists for analytical cross‐sectional studies and qualitative research. Thematic analysis was performed using nVivo software.ResultsOf the 3054 studies identified, 24 studies met the inclusion criteria. Data synthesis produced five key themes: (1) Response to diagnosis, (2) Experiences with self‐management, (3) Interactions with the healthcare system, (4) Mental health challenges and (5) Facilitators and barriers to support. Women with GDM from CALD and non‐CALD backgrounds similarly expressed mental health challenges, feeling burdened by recommendations, and challenges interacting with healthcare professionals (HCP). The major difference in experience was the cultural relevance of recommendations, especially related to diet recommendations.ConclusionGestational diabetes mellitus is a burdensome diagnosis for CALD and non‐CALD women, with CALD women uniquely experiencing a lack of culturally relevant recommendations for self‐management. The similarities and differences in experience call for optimisation of GDM management and support for women with GDM.
