Body surface area: a new anthropometric measurement for diabetic retinopathy in Chinese adults with type 2 diabetes: a hospital registry case-control study

摘要

To the Editor: Diabetic retinopathy (DR) is a condition characterized by retinal microvascular damages of diabetes mellitus. As the primary cause of blindness in adults, DR has already become a public health problem worldwide and threatens the outcomes of diabetic patients and even healthy population. The correlation between DR and common anthropometric measurements represented by body mass index (BMI) was still controversial.[1] Another basic anthropometric index also calculated by height and weight, body surface area (BSA) could more accurately reflect the size of body, and distinguish adipose or muscle tissues.[2] In addition, previous research considered that adipokines secreted from adipose tissue might play an important role in the mechanism of obesity and type 2 diabetes. The level of adiponectin decreased in obese people and lower adiponectin might cause insulin resistance and diabetes.[3] We firstly investigated the relationship between BSA and DR in Chinese type 2 diabetic patients, and compared it with BMI. The study was approved by the Institutional Review Board of the First Affiliated Hospital of China Medical University (AF-SOP-07-1.1-01/2019-13). Written informed consent was obtained for the entire study population included in this study.
