研究目的:

主要目标: 1、建立孕期不同阶段(早、中、晚期)血糖波动指标(如TIR、MAGE、CV%)与母婴不良结局(如LGA、新生儿低血糖)的量化关联模型。 2、提出基于CGM的血糖波动阈值(如TIR<65%、MAGE>3.0 mmol/L),用于临床预警和干预指导。 次要目标: 1、解析血糖曲线时间特征峰(如黎明现象、餐后峰值)与母婴结局的关系。 2、比较GDM与非GDM人群的血糖波动模式差异。 3、探讨血糖波动指标与产后糖尿病风险的长期关联(产后42天OGTT)。  

Objectives of Study:

Main Objectives: 1. To establish a quantitative association model between glycaemic fluctuation indicators (e.g. TIR, MAGE, CV%) and adverse maternal and infant outcomes (e.g. LGA, neonatal hypoglycaemia) at different stages of pregnancy (early, middle and late). 2.To propose CGM-based thresholds for blood glucose fluctuation (e.g. TIR<65%, MAGE>3.0 mmol/L) for clinical early warning and intervention guidance. Sub-objectives: 1, To resolve the relationship between the temporal characteristic peaks of the blood glucose curve (e.g. dawn phenomenon, postprandial peak) and maternal and infant outcomes. 2、Compare the differences in blood glucose fluctuation patterns between GDM and non-GDM populations. 3, Explore the long-term association between blood glucose fluctuation indicators and the risk of postpartum diabetes mellitus (42-day postpartum OGTT).
