[摘 要] 目的:探讨孕中、晚期妊娠期糖尿病(gestational diabetes mellitus,GDM)母体糖脂代谢指标和甘油三酯葡萄糖乘积
(triglyceride⁃glucose,TyG)指数与GDM巨大儿的相关性。方法:基于GDM队列,根据严格入组和排除标准选择2022年1—8月
于南京市妇幼保健院剖宫产分娩的产妇,按照有无 GDM 和新生儿出生体重分为正常对照组(NC,n=23)、GDM 非巨大儿组
(GDM⁃N,n=23)和GDM巨大儿组(GDM⁃M,n=23)。收集3组一般资料和孕中、晚期糖脂代谢指标,计算TyG指数和胰岛素抵抗
指数(HOMA⁃IR),采用Spearman相关检验和线性回归模型分析母体孕中、晚期各指标与GDM巨大儿的相关性。结果:孕中期
GDM⁃M 组母体空腹血糖(fasting plasma glucose,FPG)、糖化血红蛋白(glycated hemoglobin,HbA1c)和TyG水平升高,直接胆红
素(direct bilirubin,DBIL)和肌酐(creatinine,Cr)水平降低,餐后1 h、2 h血糖水平高于NC组,但低于GDM⁃N组(P < 0.05),孕晚
期C肽(C⁃peptide,CP)、甘油三酯(triglycerides,TG)、HbA1c和TyG升高,丙氨酸氨基转移酶(alanine aminotransferase,ALT)高于
NC 组,低于 GDM⁃N 组(P < 0.05)。Spearman 相关检验提示,新生儿出生体重与母体孕中期 FPG、HbA1c 以及孕晚期 CP、
HbA1c、TG、TyG呈正相关(P < 0.05),与孕中期DBIL、Cr呈负相关(P < 0.05)。多因素线性回归模型分析结果显示,孕中期母体
FPG、HbA1c 和 DBIL,孕晚期 HbA1c、TG 和 TyG 指数为巨大儿的影响因素(P < 0.05)。结论:孕中、晚期母体糖脂代谢指标及
TyG指数与GDM巨大儿的发生密切相关,HbA1c、FPG、TG和TyG可作为GDM巨大儿发生的重要监测评估指标。

[Abstract] Objective:To investigate the correlation between maternal glucose and lipid metabolism indicators,triglyceride⁃glucose
(TyG)index,and macrosomia in gestational diabetes mellitus(GDM)during the second and third trimesters of pregnancy. Methods:
Based on a GDM cohort,pregnant women who underwent cesarean section delivery at the Nanjing Maternity and Child Health Hospital
from January to August 2022 were selected according to strict inclusion and exclusion criteria. Participants were divided into three
groups based on GDM status and newborn birth weight:normal control group(NC,n=23),GDM non⁃macrosomia group(GDM⁃N,n=
23),and GDM macrosomia group(GDM⁃M,n=23). General information and glucose and lipid metabolism indicators from the second
and third trimesters were collected for all three groups. The TyG index and the homeostasis model assessment of insulin resistance
(HOMA⁃IR)were calculated. Spearman correlation analysis and linear regression models were used to analyze the correlation between
maternal indicators in the second and third trimesters and GDM macrosomia. Results:In the second trimester,the GDM⁃M group
showed elevated levels of fasting plasma glucose(FPG),glycated hemoglobin(HbA1c),and TyG index,while direct bilirubin(DBIL)
