目的
2
探究甘油三酯-葡萄糖体质指数(triglyceride-glucose body mass index,TyG-BMI)、动脉粥样硬化指数(atherogenic index of plasma,AIP)联合餐后血糖波动(postprandial glucose excursions,PPGE)对2型糖尿病(type 2 diabetes mellitus,T2DM)患者肌少症的预测价值。
方法
2
本研究为观察性横断面研究,选取2023年1月至2024年12月在重庆医科大学附属第一医院内分泌科住院治疗的T2DM患者590例,其中男性322例,女性268例。收集其一般人口学资料及关键代谢指标[空腹血糖(fasting plasma glucose, FPG)、餐后2 h血糖(postprandial 2-hour plasma glucose, PPG)、甘油三酯(triglyceride, TG)等],计算TyG-BMI、AIP和PPGE。按照亚洲肌少症工作组(Asian Working Group for Sarcopenia, AWGS)2019年标准诊断肌少症,并据此将患者分为肌少症组(
n
=140)与非肌少症组(
n
=450)。对2组患者进行1∶1倾向性评分匹配(propensity score matching, PSM),匹配后纳入肌少症组与非肌少症组各102例。比较2组FPG、PPG、TyG-BMI、AIP和PPGE等代谢指标的差异,进行Spearman相关分析,并采用条件Logistic回归模型分析T2DM患者肌少症的影响因素,并绘制受试者工作特征(receptor operating characteristic, ROC)曲线评估预测效能。收集20
23年1月至2024年12月在陆军军医大学第一附属医院江北院区内分泌科的192例外部数据进行模型验证。
结果
2
PSM后,2组的基线资料均衡。肌少症组的PPG、AIP和PPGE水平均值较非肌少症组更高, TyG-BMI指数则更低(
P=
0.001)。Spearman相关分析显示,TyG-BMI指数与T2DM患者肌少症呈显著负相关(
r
=-0.404,
P=
0.001),AIP和PPGE与T2DM患者肌少症均呈显著正相关(
r
=0.280,
P=
0.001;
r
=0.372,
P=
0.001)。条件Logistic回归分析显示,AIP(
OR
=14.367)和PPGE(
OR
=1.245)为T2DM患者肌少症的独立危险因素,TyG-BMI指数(
OR
=0.966)为T2DM患者肌少症的独立保护因素。ROC曲线显示,联合应用TyG-BMI指数、AIP和PPGE的预测模型曲线下面积(area under the curve, AUC)为0.918,外部验证中AUC为0.954,敏感度和特异性均优。
结论
2
TyG-BMI指数、AIP及PPGE是T2DM患者肌少症的重要代谢预测指标,三者联合应用具有良好的2型糖尿病患者肌少症筛查价值与外部适用性。
Objective To evaluate the predictive value of triglyceride-glucose body mass index (TyG-BMI)
atherogenic index of plasma (AIP)
and postprandial glucose excursion (PPGE) for sarcopenia in patients with type 2 diabetes mellitus (T2DM). Methods An observational cohort trial was conducted on 590 hospitalized T2DM patients (322 males and 268 females) admitted to Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University between January 2023 and December 2024. General demographic data and key metabolic indicators
including fasting plasma glucose (FPG)
postprandial 2-hour plasma glucose (PPG)
triglyceride (TG) were collected
and then TyG-BMI
AIP
and PPGE were calculated. Based on the Asian Working Group for Sarcopenia (AWGS) 2019 criteria
they were divided into a sarcopenia group (
n
=140) and a non-sarcopenia group (
n
=450). After 1∶1 propensity score matching (PSM)
102 patients with sarcopenia were matched with 102 without. Differences in metabolic indicators FPG
PPG
TyG-BMI
AIP and PPGE were compared between the 2 groups. Spearman correlation analysis was conducted to assess correlations of these indicators with sarcopenia.
Conditional logistic regression analysis was performed to identify independent risk factors
and receiver operating characteristic (ROC) curves were plotted to assess predictive performance. An external validation cohort consisting of 192 T2DM patients from Department of Endocrinology of Jiangbei Branch of First Affiliated Hospital of Army Medical University between January 2023 and December 2024 was included to validate the prediction model. Results After PSM
the baseline data of the 2 groups was balanced (
P
>
0.05). The sarcopenia group showed higher levels of PPG
AIP
and PPGE
but lower TyG-BMI value than the non-sarcopenia group (all
P
=0.001). Spearman correlation analysis revealed that the TyG-BMI was negatively correlated (r=-0.404
P
=0.001)
whereas AIP and PPGE were positively correlated with concomitant sarcopenia (r=0.280
P
=0.001;
r
=0.372
P
=0.001) in the T2DM patients. Conditional logistic regression analysis identified AIP (
OR
=14.367) and PPGE (
OR
=1.245) as independent risk factors
while TyG-BMI (
OR
=0.966) as independent protective factors. ROC curve analysis revealed that the area under the curve (AUC) of the combined model of TyG-BMI
AIP and PPGE in predicting sarcopenia was 0.918
and the AUC value was 0.954 in external validation
with good sensitivity and specificity. Conclusion TyG-BMI
AIP
and PPGE are important metabolic predictors in T2DM patients with sarcopenia. Their combination has good screening value for sarcopenia
and can be applied in external prediction for T2DM patients.
