The VALID-II study, sponsored by Thai Binh University of Medicine and Pharmacy, addresses a critical public health issue in Vietnam, where GDM is prevalent but often poorly managed due to lack of systematic screening and support. The intervention aims to enhance self-care practices among pregnant women with GDM by leveraging informal support networks, which may improve maternal and neonatal health outcomes. The market potential is significant, given the rising incidence of diabetes in low- and middle-income countries. Successful implementation could position the sponsor as a leader in innovative diabetes management solutions in Southeast Asia, potentially attracting partnerships or funding for broader applications. Competitive implications include the need to monitor similar interventions in the region and the global landscape of diabetes management solutions.
