Key finding
Change difference −0.95 kg, 95% CI −1.87 to −0.04; p=0.04. Intervention −0.23 kg vs usual care +0.72 kg
This study tested a lifestyle programme for new mothers who had gestational diabetes, to help prevent later type 2 diabetes. Women in the programme maintained their weight while those receiving usual care gained weight over 12 months. However, most women did not fully participate in the programme, and there were no clear improvements in waist size or blood sugar.

Study focus
This study tested a lifestyle programme for new mothers who had gestational diabetes, to help prevent later type 2 diabetes. Women in the programme maintained their weight while those receiving usual care gained weight over 12 months. However, most women did not fully participate in the programme, and there were no clear improvements in waist size or blood sugar.
Women who have had gestational diabetes are about seven times more likely to develop type 2 diabetes later in life. Finding ways to reach this younger population early is critical. This study shows a lifestyle programme can help prevent postnatal weight gain, which is a key risk factor. But the low engagement highlights that programmes need to be designed around the realities of new motherhood and competing family demands.
Low programme engagement: only 10% completed all sessions High attrition: 27% loss to follow-up in intervention group Baseline glucose profiles were near normal, limiting ability to detect changes Primary outcome (weight) significant but other primary outcomes (waist, glucose) non-significant
↓ Weight gain prevented: intervention group stable vs usual care +0.72 kg (difference −0.95 kg, p=0.04)
↔ Waist circumference: no significant difference between groups
↔ Fasting blood glucose: no significant difference between groups
