Abstract:

Excessive gestational weight gain（GWG）is closely associated with elevated blood pressure（BP）levels，postpartum weight retention and obesity.Recent studies have shown that the maximum GWG rate occurs between 22+0 to 26+0 weeks of gestation，which is a critical time window associated with diastolic BP rebound.Interventions that target this period may improve maternal and fetal outcomes by optimizing GWG and BP levels.

Key words: gestational weight gain, blood pressure, cardiovascular risk

摘要：

孕期增重过度与血压升高、产后体重滞留和肥胖关系密切。近期研究显示，妊娠中晚期（孕22~26周）的增重率处于整个孕期的峰值，是与舒张压升高有关的体重管理“窗口期”。以此时间窗为切入点的干预措施，有望通过体重管理调节血压增幅，进而改善母胎预后。
