Hyperuricemia among Mongolian adults and the related factors in Inner Mongolia Autonomous Region from 2018 to 2020

Abstract

To understand the epidemiological characteristics of hyperuricemia(HUA) in Mongolian adults in Inner Mongolia Autonomous Region, and to explore the related factors. Using multi-stage stratified and population proportional cluster random sampling investigated 2301 Mongolian population aged 18 and older living in Inner Mongolia Autonomous Region from August 2018 to August 2020. The participant general demographic data, personal life and behavior history and diet were collected, and participant physical examination and blood biochemical tests were performed. The prevalence of HUA was counted, and the risk factors were analyzed by Logistic regression analysis and decision tree model. The prevalence rate of HUA in Mongolian adult population was 19.74%, and the standardized prevalence rate was 21.07%. Male(26.3%) was higher than female(15.6%), and there were significant differences in the prevalence rate among populations with different height, weight, occupation, education level and regions(P<0.05), Logistic regression analysis showed that the occurrence of HUA and overweight and obesity(OR=2.002, 95%CI 1.519-2.638), and dyslipidemia(OR=1.620, 95%CI 1.271-2.064), abnormal blood glucose(OR=1.563, 95%CI 1.195-2.046), pork(OR=1.231, 95%CI 1.139-1.330), mutton(OR=1.287, 95%CI 1.179-1.404), poultry meat(OR=1.111, 95%CI 1.024-1.206), alcohol drinking alcohol(OR=1.145, 95%CI 1.008-1.302) showed a positive correlation. It was negatively associated with women(OR=0.641, 95%CI 0.498-0.827), manual labor(OR=0.629, 95%CI 0.477-0.829), beans and their products(OR=0.889, 95%CI 0.811-0.976), milk and milk intake(OR=0.854, 95%CI 0.785-0.921). The result of decision tree model showed that pork intake, overweight and obesity, dyslipidemia, mutton intake and gender were the variables affecting HUA. The prevalence of HUA in the Mongolian population was relatively high, and the gender, occupation, body mass index, blood lipid, blood glucose and some dietary factors were all associated with HUA.
