Methods: Data comes from prospective cohort study (n= 1393, mean follow up= 9.46 year). Participants were classified into four groups through a combination of the Chinese Diabetes Society diagnostic criteria for metabolic syndrome with anthropometric measurements. Cox regression models with time-dependent covariates were used to evaluate changes in obesity metabolic phenotypes and risk of T2DM. Results: Participants in MUO state had the highest risk of developing T2DM, the incidence density was 12.10/1000 person-year. The MHO and MUO groups showed an increased risk of incident diabetes based on body mass index (HR, 1.29; 95% CI, 1.03-1.61; P=0.026 and HR, 1.20; 95% CI, 1.02-1.40; P=0.024 respectively.) Besides, the MHO group had an increased risk of incident diabetes based on waist circumference (HR, 1.41; 95% CI, 1.10-1.80; P=0.006). Conclusions: Diabetes is more frequent in the MHO and MUO groups and co-occurrence of obesity and metabolic abnormalities contributes to the development of T2DM.
