Harnessing Human Potential and Improving Health Span in Women and Their Children

Women with Gestational Diabetes Mellitus (GDM) are 12-times more likely to develop Type 2 Diabetes (T2D) 4-6 years after delivery than women without GDM. There has been evidence that lifestyle modifications such as physical activity (PA), dietary intake, sleep, and stress management can prevent or delay type 2 diabetes (T2D). The purpose of this study is to assess the efficacy of a holistic lifestyle digital health intervention with post-GDM women in large community settings in Singapore. The study consists of a 1-year randomized controlled trial (RCT) with 3 years follow-up. Women who are eligible for the study will be randomized to either Group 1 (Intervention) or Group 2 (Control) at baseline. Both groups will be followed in years 2-4. Women from both groups will be provided with an Oura ring for tracking physical activity, sleep, and heart rate variability (a proxy for stress), and the "HAPPY app," which will provide health promotion information about physical activity, diet, sleep, and mental wellbeing, as well as display the information collected (such as body mass index, blood pressure, and OGTT results). The active group will receive the "LVL UP app" a smartphone-based chatbot-delivered intervention, designed to provide personalized recommendations through multiple digital coaching sessions aimed at improving health literacy and practicing healthy lifestyles to prevent Type 2 diabetes and common mental disorders (i.e., anxiety, depression).
