Abstract

Aims: It is unknown whether low serum uric acid (hypouricemia) is associated with diabetes diagnosis. This study aimed to investigate this association in Chinese adults.

Methods: This cross-sectional study included 22,546 Chinese adults. The reference interval for serum uric acid was determined in a sub-group of healthy individuals. The association between hypouricemia and diabetes was analyzed using binary logistic regression.

Results: The serum uric acid reference intervals were 3.78–8.31 mg/dL for males and 2.76–6.24 mg/dL for females. Hypouricemia was defined as serum uric acid concentration <3.78 mg/dL for males and <2.76 mg/dL for females. Hypouricemia was associated with an increased likelihood of diabetes diagnosis in both unadjusted (odds ratio [OR], 2.23; 95% confidence interval [CI], 1.78–2.79) and risk factor adjusted (OR, 2.67; 95% CI, 2.08–3.43) analyses. In a sub-group analysis, hypouricemia was significantly independently associated with an increased likelihood of diabetes diagnosis in males but not females.

Conclusion: This study suggests that hypouricemia is independently associated with an increased risk of diabetes diagnosis. The findings should be validated in prospective cohort studies.
