SUN-524 M-health Lifestyle Intervention For Latinas With Recent Gdm

Abstract Disclosure: E.W. Seely: None. S. Trabelsi: None. S.E. Levkoff: None. S.V. Romero: None. D. Cortes: None. BackgroundHispanic women have 1.5 times higher risk for gestational diabetes (GDM) versus non-Hispanic women and are less likely to engage in healthy eating and physical activity. Few interventions addressing T2DM risk in Latinas with prior GDM exist. Our initial pilot of 21 women over 6 weeks showed significant improvement in self-efficacy (SE) for healthy eating (p=0.003) and physical activity (p=0.007). Weight did not change significantly (p=0.16) (Seely et al., 2020). Based on the pilot, this 6-month study tests the culturally tailored m-health program (¡Hola Bebé, Adios Diabetes!) to reduce weight and improve SE for healthy eating and physical activity in Latinas with recent GDM. MethodsLatinas with GDM in the prior 5 yrs who owned a smartphone and without T2DM were recruited via Lynn and Brookside Community Health Centers (MA) or via User Interviews online platform. Baseline weights were obtained by a community health worker (CHW) or by subjects sending photos of weights on study provided scales. All materials were in Spanish and English. The Hola Bebé, Adios Diabetes! App included: weight tracking, 12 audio-visual modules on healthy eating and physical activity, customizable motivational messages, community forum and guidance from a health educator. A rewards system with badges for completing modules and action plans was available. Descriptive statistics (mean, sd), paired t-tests for normally and Wilcoxon rank sum for non-normally distributed data were used.​ Weight (primary outcome) from baseline to end of study via follow-up visit with the CHW or by subject sending a photo of weight on a study-provided scale, SE for healthy eating and physical activity (secondary outcomes) were measured using Sallis scales. Post-intervention structured interviews were performed.Results93 subjects had baseline and 65 had followup weights (30% non-completion). There was statistically significant weight loss (194.1 + 48.8 to 186.8 +48 lbs, p<0.001) and increase in healthy eating SE (p = 0.018) with no change in physical activity SE (p=0.34).88% of subjects reported improvement in diet and eating habits. 84% reported an increase in physical activity. 81% said they would recommend the app to others with prior GDM. Recommendations included longer exercise videos, more variety in lessons and more ability to personalize the app. Conclusion Our culturally tailored/bilingual app provided remote access to Latinas disproportionately affected by GDM and improved T2D risk factors by decreasing weight and improving healthy eating SE. Though physical activity SE did not increase, subjects reported improvement in physical activity habits. Future research should incorporate suggested changes, increase program completion rates and evaluate the ¡Hola Bebé, Adios Diabetes! app program in an RCT. Presentation: Sunday, July 13, 2025
