The Habits Program, however, is not specifically designed for the management of GDM. Working with the Department of Obstetrics and Gynecology we have developed a workflow to manage patients with GDM by optimizing blood glucose control through lifestyle modification and achieving optimal GWG. We have worked with Jana Care to develop 'Habits-GDM' - an app modified from the Habits Program which is designed specifically to support this workflow, which takes into account the nutritional requirements and limitations on exercise during pregnancy, and the need to prevent excessive weight gain (as opposed to weight loss in the original Habits Program). The program has been customized for use in Singapore including translation (with modification of messaging) and a Singapore food database.
