BackgroundThe risk of developing type 2 diabetes mellitus (T2DM) is up to 50% among women with gestational diabetes mellitus (GDM). GDM also increases risks for pre-term birth, macrosomia, fetal hypoglycemia, and C-section delivery. Education for expectant mothers with GDM about nutrition, exercise, and the risks of developing T2DM after delivery enhances the probability of postpartum diabetes screening. However, the availability of diabetes education is limited. To bridge this gap, our team developed four training modules on GDM tailored for nurses and community health workers. This pilot study assesses changes in knowledge, self-efficacy for providing diabetes education, attitudes, and intentions to recommend diabetes prevention before and after training completion.MethodsThese interactive online modules, each lasting 45–60 minutes and featuring engaging case studies and integrated knowledge assessment questions, were disseminated through various professional organizations to clinical staff providing care for women with GDM. Optional pre- and post-training surveys were conducted to gauge the effectiveness of the modules. Collected data did not follow a normal distribution pattern. We provided an overview of the baseline characteristics of the population, self-efficacy, attitudes, intentions, and GDM knowledge by calculating the median scores and interquartile ranges. We assessed the changes in scores on self-efficacy, attitudes, intentions, and GDM knowledge before and after training using non-parametric Wilcoxon matched-pair signed rank tests.ResultsEighty-two individuals completed baseline evaluation and 20 individuals accessed all modules and completed post-training assessments. Among those completing the training, improvement was noted in GDM knowledge [56.5% (16.0) v. 78.3% (22.0), p < 0.001], Self-efficacy for providing diabetes education [6.60 (2.73) v. 9.33 (0.87), p < 0.001], attitudes toward the value of tight control [4.07 (0.79) v. 4.43 (0.86), p = 0.003], and intentions to recommend diabetes prevention measures [4.81 (0.63) v. 5.00 (0.00), p = 0.009)].ConclusionsCompletion of our interactive online modules improved knowledge, intention to recommend diabetes prevention methods, self-efficacy to provide diabetes education, and attitudes toward the value of tight control among individuals caring for women with GDM. Enhanced accessibility to such curricula is crucial to improve access to diabetes education.Trial registrationThis study was registered atclinicaltrials.gov, identifier:NCT04474795.
