Association between uric acid levels and incidence of type 2 diabetes: Population-based Panasonic cohort study 11.

ABSTRACT

AIMS: This cohort study intended to assess the association between serum uric acid levels and incidence of type 2 diabetes in a Japanese population. METHODS: Individuals who participated a medical health checkup program carried out by Panasonic Corporation from 2008 to 2018 were included in this study. A total of 122,123 participants (92,718 men and 29,405 women) were included. During the research period, 6,386 participants developed type 2 diabetes. RESULTS: Multivariate analysis showed that, in men, serum uric acid levels were not significantly associated with incident type 2 diabetes after adjusting for diabetes risk factors. However, in women, the risk of type 2 diabetes incidence was higher in the group with uric acid levels 5.1-6.0 mg/dL (hazard ratio, 2.01 [95 % confidence interval 1.26-3.42]) or > 6.1 mg/dL (hazard ratio, 1.85 [95 % confidence interval 1.11-3.22]) than in the group with uric acid levels ≤ 3 mg/dL. Furthermore, in women, the area under the receiver operating characteristic curve and optimized cut-off values of uric acid for the incidence of type 2 diabetes at 10 years were 0.720 and 4.8 mg/dL, respectively. CONCLUSIONS: Serum uric acid levels were associated with incident type 2 diabetes in Japanese women but not in Japanese men.
