Background The prevalence of Gestational Diabetes Mellitus (GDM) in Arabic-speaking countries varies from 1.2 % (Jordan) to almost 40 % (Saudi Arabia). Untreated GDM increases the risk of poor maternal and neonatal health outcomes. Objective This systematic scoping review aims to examine the current literature to determine the effectiveness of interventions designed to manage and prevent GDM across Arabic-speaking countries. Design Systematic scoping review. Methods Employing the PRISMA-ScR and the AND-EAL for study quality and bias assessment, a comprehensive review of the literature was conducted using 12 databases and search terms relevant to GDM interventions conducted across the League of Arab states. The search period includes intervention studies published up to and including August 31st, 2024. Findings Eight studies met the inclusion criteria. Interventions conducted included those modeled on the Health Behavior Change model, Theory of Reasoned Action and the PRECEDE model, constructs of Social Cognitive Theory including self-efficacy, GDM self-management, lifestyle management and BASNEF model-based empowerment. The intervention studies had positive effect on GDM knowledge, self-efficacy, A1C levels, quality of life, maternal and neonatal outcomes. Conclusion Prevention and management of GDM is important in addressing maternal and neonatal health outcomes. Interventions designed with a theoretical framework and those that are culturally tailored are more likely to elicit behavior change.
