Diabetic control assessed by MFBG or HbA1c was the significant risk factor correlated with the incidence and progression of retinopathy.

In the prevention of macrovascular diseases, effective intervention of the nondiabetic cardiovascular risk factors may be as important as or even more important than the good control of diabetes.

Background and Objectives: The aim of this study was to investigate the relationships between obesity-related factors including body mass index (BMI), diabetes or prediabetes, hyperlipidemia, fasting plasma glucose, fasting plasma insulin, homeostasis model assessment-estimated insulin resistance (HOMA-IR), highly sensitive C-reactive protein (hs-CRP) and Graves’ orbitopathy (GO). Materials and Methods: Eighty-four patients with Graves’ disease (GD) (42 without GO and 42 with GO) were enrolled in this cross-sectional cohort study. Gender, age, GD treatment history, height, body weight, waist circumference, smoking status, co-morbidities, levels of free thyroxin, thyroid-stimulating hormone, thyroid-stimulating hormone receptor (TSHR) antibodies, fasting plasma glucose and insulin, and hs-CRP were recorded. The eye condition was evaluated using the consensus statement of the European Group of Graves’ Orbitopathy (EUGOGO) and the NOSPECS classification. Results: In this study, multivariate regression analysis showed that BMI, fasting plasma insulin, and HOMA-IR were associated with the presence of GO after adjusting the age, gender, smoking, TSHR antibodies, and steroid usage (adjusted odd’s ratio (aOR) 1.182, 95% confidence interval (95% CI), 1.003–1.393, p = 0.046; aOR 1.165, 95% CI, 1.001–1.355, p = 0.048; and aOR 1.985, 95% CI, 1.046–3.764, p = 0.036, respectively). In addition, BMI, fasting plasma glucose, fasting plasma insulin, HOMA-IR, and hs-CRP levels were positively correlated with the severity of GO. Conclusions: The findings of this study suggest that obesity-related factors, especially fasting plasma insulin and HOMA-IR, are related to GO. Our study highlighted the importance of obesity-related factors in GO. Obesity-related factors may cause the development of GO or occur simultaneously with GO.
