Study on the prevalence of hyperuricemia and its relationship with chronic kidney disease in the urban residents of Yunnan plateau area / 中华肾脏病杂志

ABSTRACT

Objective To investigate the prevalence of hyperuricemia (HUA) and its relationship with chronic kidney disease (CKD) among the population of Yunnan Plateau area.Methods Residents aged over 18 years old (n=4581) in the city of Yuxi,a community where original inhabitants were relatively concentrated,were randomly chosen for screening cross-sectional.Fasting blood and urine samples were collected to detect blood and urine parameters.Results The prevalence of HUA in the community residents was 25.91％,of which the prevalence of HUA was 34.15％ in male and 15.55％ in female.The prevalence of HUA in men was higher than that in women,and the difference was statistically significant (P ＜ 0.01).In the age of 30-49 years old,the prevalence of HUA was higher than that in other age groups (P ＜ 0.01).Multivariate logistic regression analysis showed that HUA,age,gender,hyperglycemia,low HDL levels were independently associated with CKD (P ＜ 0.05).In addition,high blood uric acid (≥404 μmol/L) group has a higher risk of CKD than low blood uric acid (≤282 μmol/L) group,when divided into four groups according to the blood uric acid level (OR=3.447,95％ CI 2.218-5.375,P＜0.01).Conclusions HUA is independently associated with CKD.The prevalence of HUA in community residents of Yunnan Plateau (Yuxi) is different from their counterparts in eastern coastal area and the data of developed regions reported by studies in past 10 years.
