Notably, some patients have good glucose control but still develop vascular complications, whereas some patients have retinopathy with neither nephropathy nor neuropathy. This study will be performed to explore the risk factors for T2DM complications in Chinese patients.Methods and analysis: Patients with T2DM and healthy people will be recruited from Hebei General Hospital from September 2019 to September 2020. The subjects will be grouped into a control group, T2DM without vascular complications group, T2DM with macrovascular complications group, and T2DM with microvascular complications group; they will then be further subgrouped. The following data will be collected after admission: demographic information such as age, sex, and education; relevant medical history such as duration of diabetes, family history of first-degree relatives with diabetes, and age at diagnosis of diabetes; and anthropometric and blood indicators such as weight, waist circumference, fasting blood glucose level, C-peptide level, total cholesterol level, and triglyceride level. The statistical analysis will be performed using SPSS 22.0 (IBM Corp., Armonk, NY, USA). A P value of <0.05 will be considered statistically significant. The χ2 test, one-way analysis of variance and the rank sum test will be used to analyze differences between the groups. Logistic regression will be used to analyze the risk factors for macrovascular and microvascular complications of T2DM.Keywords: diabetes mellitus, type 2, diabetic angiopathies, risk factors
