Cohort study 

研究目的:

本研究是一项临床观察研究,通过前瞻性队列研究设计,经患者本人知情同意后,根据患者自愿选择是否在餐前饮用牛奶,分为暴露组(饮用餐前牛奶)和非暴露组(不饮用餐前牛奶),观察餐前牛奶对妊娠期高血糖患者的血糖管理的效果,以及减少不良妊娠结局发生的效果。  

Objectives of Study:

This study is a clinical observational study, a prospective cohort study design.After informed consent from the patients, we divided the patients into an exposed group (drinking milk before meals) and a non-exposed group (not drinking milk before meals) based on their voluntary choice. The purpose was to observe the effect of pre-meal milk on glycemic management in patients with hyperglycemia in pregnancy and the effect of reducing the occurrence of adverse pregnancy outcomes.
