We then established a retrospective cohort of 4835 nondiabetic subjects at baseline with complete annual health evaluation records through 2019. The median follow-up time was 4.8 (3.0– 7.3) years.Results: The overall prevalence of GADA was 0.53% and was higher in diabetic subjects (1.25%) than in nondiabetic subjects (0.47%). We found a decrease in baseline body mass index (BMI) from the GADA- to GADAhigh subgroups among baseline diabetic and prediabetic patients and also those who developed diabetes later in the cohort study. A total of 136 subjects (2.8%) developed diabetes after a median follow-up of 3.5 years. For GADA+ participants, BMI was not associated with the risk for diabetes. In the Cox regression model, the GADAlow and GADAhigh exhibited 2.63-fold and 4.16-fold increased risk for diabetes, respectively. This increased risk for diabetes by GADA-positivity is only found in male adults (HR 4.55, 95% CI 2.25– 9.23).Conclusion: GADA has a low prevalence in China but is associated with a 2.63– 4.16-fold increased risk for diabetes.Keywords: autoimmune diabetes, glutamic acid decarboxylase antibody, latent autoimmune diabetes in adults, obesity, prevention
