Summary for postnatal weight retention or return to pre‐pregnancy weight for women with GDM

Ineffective or possibly harmful interventions: indicating that the review found moderate to high‐quality evidence of lack of effectiveness for an intervention Moderate‐quality evidence showed no clear difference for return to pre‐pregnancy BMI (at follow‐up, timing not defined) for women with GDM who were treated with exercise versus control. No conclusions possible: low‐ to very low‐quality evidence, or insufficient evidence to comment on the effectiveness, more evidence needed Low‐quality evidence suggested benefit by an increased number of women meeting postpartum weight goals, that is returning to their pre‐pregnancy weight at twelve months postpartum for women with GDM who were treated with lifestyle intervention compared to usual care or diet alone. Low‐quality evidence showed no clear difference for postnatal weight retention or return to pre‐pregnancy weight at six weeks postpartum for women with GDM who were treated with lifestyle intervention versus usual care or diet alone or insulin versus oral therapy up to one‐year follow‐up. Very low‐quality evidence showed no clear difference for postnatal weight retention or return to pre‐pregnancy weight at three months postpartum for women with GDM who were treated with low‐GI diet versus high‐fibre moderate‐GI diet; or lifestyle intervention versus usual care or diet alone at eight months postpartum
