Conclusions
PIH, GDM
GDM
This study significantly reduced the incidence of GDM and PIH through health education, nutritional intervention and weight management for pregnant women at high risk of GDM, and provided a reliable basis for promoting lifestyle interventions in high-risk groups of GDM in the future. The long-term effects of GDM on patients and their offspring cannot be ignored, but due to the limitation of study time, the follow-up time of this study is not long enough to see the longer-term effect of lifestyle interventions, and the follow-up time needs to be extended to further observe the long-term effects of lifestyle interventions on mothers and offspring.
