1. GDM gestational diabetes; kg = kilograms; sd = standard deviation; PP = postpartum
2. 1Values are based on the 16 participants with complete weight data at 6 weeks and 30 weeks postpartum
3. 2mean change represents the mean difference in weight retention at 6 weeks and 30 weeks postpartum
4. 3postpartum weight goal was a return to the weight at the earliest first trimester visit or a 5 % weight loss, whichever was greater
5. represents percentage change in the proportion of participants meeting or exceeding their weight loss goal
