Relationship between hyperuricemia and cardiovascular risk factors among outdoor male traffic policemen / 中国职业医学

ABSTRACT

OBJECTIVE: To comprehend the prevalence status of elevated serum uric acid(SUA) and investigate the relationship between elevated SUA and cardiovascular risk factors and the clustering of the cardiovascular risk factors among outdoor male traffic policemen. METHODS: Selected by convenience sampling,1 039 outdoor traffic policemen in Guangzhou were asked to complete a questionnaire survey,physical and laboratory examination. According to the level of SUA > 420. 00 μmol/L or not,they were divided into elevated SUA group and control group. RESULTS: The median SUA level of outdoor male traffic policemen was 431. 00 μmol/L,and the elevated SUA prevalence was 56. 3%. The length of working years,systolic blood pressure,diastolic blood pressure,and levels of serum triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),and serum creatinine(Scr) in the elevated SUA group were statistically higher than the control group(P < 0. 01). The high density lipoprotein cholesterol level was lower in the control group than that in the elevated SUA group(P < 0. 01). After adjusting for age and alcohol consumption,the results of multivariate logistic regression analyses showed that outdoor traffic policemen who suffer from overweight or obesity,elevated TG and elevated TC have more risk in suffering from elevated SUA(P < 0. 05). The odds ratios(ORs) and 95%confidence intervals(CIs) were 2. 347(1. 772-3. 109),2. 040(1. 517-2. 743) and 1. 431(1. 080-1. 896) respectively.The risk factors of suffering from elevated SUA increased along with the increase of outdoor working years or Scr level(P <0. 05). The ORs and 95% CIs were 1. 028(1. 004-1. 054) and 1. 048(1. 033-1. 062) respectively. The proportion of people with elevated SUA among outdoor traffic policemen increased with the increase of cardiovascular risk factors(P <0. 01). The risk of elevated SUA among outdoor male traffic policemen who have 1,2,3,4 and ≥5 cardiovascular risk factors were 1. 583,2. 351,4. 657,2. 865 and 13. 576 times higher than those without cardiovascular risk factor respectively(P < 0. 05). CONCLUSION: Among outdoor male traffic policemen,elevated SUA are closely associated with the cardiovascular risk factors. The risk factors of suffering from elevated SUA increased with clustering of cardiovascular risk factors.
