This literature review explores the role of eHealth and health coaching in assisting prevention of type 2 diabetes in women with history of gestational diabetes mellitus (GDM). The integration of electronic health (eHealth) and mobile health (mHealth) technologies, including telemedicine, smartphone apps, and mixed-method approaches, has emerged as a crucial strategy in healthcare delivery. These technologies address postnatal barriers such as lack of support, time constraints, and childcare issues, enhancing accessibility to diabetes prevention interventions. The review presents evidence from various studies, including randomized controlled trials and ongoing research projects, indicating positive impacts on engagement, adherence, and follow-up rates when utilizing remote interventions through smartphone apps and health coaching. Notably, the use of telemedicine during the COVID-19 pandemic has further underscored the potential benefits of delivering care remotely. The focus on postnatal diabetes prevention in women with a history of GDM is particularly pertinent, given the increased risk of developing type 2 diabetes. The inclusion of partners and families in interventions, highlights a holistic approach to promoting a healthy lifestyle. While the results are promising, the review acknowledges the inconclusive nature of current evidence, emphasizing the need for further research to establish the long-term efficacy and acceptance of these interventions. Continued efforts to refine these strategies and expand research will contribute to a better understanding of their impact, ultimately paving the way for targeted and effective diabetes prevention in this high-risk population of women with a history of GDM.
