Key finding
The glycemic qualification rate of the intervention group was higher than that of the control group at nearly all time points.
This study evaluated the effectiveness of WeChat group chat-based management for women with gestational diabetes compared to standard clinical prenatal care. The intervention group showed a higher glycemic qualification rate.

Study focus
This study evaluated the effectiveness of WeChat group chat-based management for women with gestational diabetes compared to standard clinical prenatal care. The intervention group showed a higher glycemic qualification rate.
Improving glycemic control in pregnant women with diabetes is crucial for reducing risks to both mothers and infants. This study suggests that digital health interventions like WeChat can enhance management strategies, potentially leading to better health outcomes without compromising traditional care methods.
The study did not assess long-term outcomes beyond the immediate postpartum period. The sample size may limit the generalizability of the findings. Effectiveness of the intervention was unclear for several outcomes.

The glycemic qualification rate was higher in the intervention group at nearly all time points.
No significant differences were found in delivery mode between the groups.
No significant differences were found in premature rupture of membranes between the groups.
No significant differences were found in preterm birth rates between the groups.
