BMJ子刊:很大体重指数MBBO能有效预测糖尿病并发症

2022-01-02 MedSci原创 MedSci原创

在诊断糖尿病时,MBBO能够预测糖尿病并发症的进展。

2型糖尿病是世界范围内发病率高的常见疾病,其并发症会降低患者的生活质量和日常生活能力。糖尿病视网膜病变 (DR) 发生在相对较早的阶段,未经治疗的DR会导致视力下降并最终失明。糖尿病肾病(DN)是最常见的需要血液透析的疾病。除非得到适当治疗,否则这两种并发症都会严重降低患者的生活质量和日常生活活动。

诊断糖尿病时,很少有因素能预测未来的糖尿病并发症。曾经有研究表示2型糖尿病发病前的最大体重指数(MBBO)可用于评估患者的胰岛素分泌能力。本研究旨在阐明MBBO在预测晚期糖尿病微血管并发症发展方面的临床价值。

这是一项横断面观察性研究。在1304名入院的2型糖尿病患者中,研究者招募了435名确诊为2型糖尿病的患者。采用单因素和多因素logistic回归分析来检查入院时MBBO或BMI是否与晚期糖尿病视网膜病变或肾病相关。为了评估这些指标的预测性能,在MBBO或BMI的各种模型中进行了交叉验证,并评估了这些分析产生的曲线下面积(AUCs)。

单变量分析表明MBBO与晚期视网膜病变和肾病相关,而入院时的BMI仅与晚期肾病相关。在多变量分析中,MBBO与晚期并发症显着相关,而入院时的 BMI 则不然。对于晚期糖尿病视网膜病变,AUC为 0.70–0.72,对于晚期肾病,AUC为0.81–0.83。在比较模型之间的AUC时,具有MBBO的模型对糖尿病并发症的预测性能很高。

总的研究显示,MBBO与晚期糖尿病并发症独立相关,而入院时的BMI则不是。高MBBO患者的糖尿病微血管并发症进展更快。在诊断糖尿病时,MBBO能够预测糖尿病并发症的进展。
