Association between serum uric acid and major chronic diseases among centenarians in China: based on the CHCCS study

Abstract

Abstract Background This study aims to analyze the distribution of serum uric acid (SUA) level based on more than 1000 centenarians and to explore the association with three common diseases including hypertension, diabetes and dyslipidemia. Methods All the 1002 centenarians from the CHCCS were included. Household survey was conducted. Results The mean SUA level of centenarians was 329.04 ± 97.75 μmol/L and the prevalence of hyperuricemia in centenarians was 26.5%. There was no statistical difference in the distribution of SUA levels among centenarians with or without hypertension/diabetes. For dyslipidemia, there was an independent positive association. The risk of dyslipidemia among those with hyperuricemia was 1.646 (95%CI: 1.078–2.298) compared with those who didn’t have hyperuricemia. By comparing different subtypes of dyslipidemia, hyperuricemia was positively associated with hypertriglyceridemia and low-density lipoprotein cholesterolemia, with the corresponding ORs of 2.553 (95%CI: 1.282–5.083) and 1.927 (95%CI: 1.273–2.917) respectively, while there was no statistically significant association with hypercholesterolemia 0.998 (95%CI: 0.574–1.732). Conclusions There was no relation between SUA with hypertension or diabetes, while there was independently and positively association with hypertriglyceridemia and low-density lipoprotein cholesterolemia. The health benefits of controlling SUA in centenarians still require evidence based on prospective studies.
