Prevalence and Influencing Factors of Hyperuricemia among Residents in Korla Region of Xinjiang

Objective To investigate the blood uric acid(BUA) level and prevalence of hyperuricemia among residents over 18 years old of four ethnic groups(Han,Uygur,Kazak,Mongolian) in Korla region of Xinjiang.Methods Stratified cluster random sampling method was used to select 2 046 residents over 18 years old from Korla region.They were surveyed with questionnaire and tested for general physical indicators and BUA.BUA level and hyperuricemia prevalence of residents of different ethnic groups were analyzed.Results The BUA levels of the Han,Uygur,Kazak,Mongolian residents in Korla region of Xinjiang were(279.31±79.49) μmol/L,(244.55±76.59) μmol/L,(264.49±77.44) μmol/L,(267.78±80.70)μmol/L,respectively.The BUA levels(F=16.42,P0.001)and hyperuricemia prevalence(P0.05) were significantly different among the four ethnic groups.Hyperuricemia prevalence was higher in men than in women in all four ethnic groups(P0.01).Hyperuricemia prevalence differed among different age groups in both men and women of Han group,women of Kazak group,and men of Mongolian group(P0.05).No difference of hyperuricemia prevalence was observed among different age groups of Uygur men and women(P0.05).Female,not drinking alcohol,drinking milk tea,triglycerides,creatinine,blood glucose,body mass index significantly affected the occurrence of hyperuricemia(P0.01).Conclusion The residents in Korla region of Xinjiang,especially those of the Han group,have high BUA level.They also have high prevalence of hyperuricemia,especially in men.Female and not drinking alcohol are protective factors,while drinking milk tea,triglycerides,creatinine,blood glucose,and body mass index are risk factors of hyperuricemia.Residents of Han group,men are highlights in the prevention and treatment of hyperuricemia in Korla region of Xinjiang.
