Objective:To explore the correlation between different smoking status and serum uric acid(SUA)in a middle-aged male in health check-up population.Methods:In this cross-sectional study, a total of 26701 middle-aged men who underwent health check-up in Taihu Sanatorium of Jiangsu Province from January 2014 to June 2015 were studied.The correlation between smoking status and SUA was analyzed by questionnaires, physical examination and serum biochemical assay.Smoking state was divided into no smoking, a occasional smoking and smoking groups.Results:With the increase of age, there was a downward trend of SUA( F=7.38, P=0.000). Among the three smoking groups, the group with occasional smoking had the highest level of SUA.The smoking group had lower level of SUA than the non-smoking group and occasional smoking group( P=0.000 and 0.005). In the non-smoking group, the fourth quartile of SUA(41.5%)had a higher percentage than that in first quartile of SUA(38.4%)( χ2=12.266, P=0.000). In the smoking group, the fourth quartile of SUA(54.9%)had lower percentage than that in the first quartile of SUA(58.4%)( χ2=7.049, P=0.008). Compared with the non-smoking group, the prevalence of hyperuricemia(HUA)in smoking group was lower( OR=0.872, 95% CI: 0.821~0.927, P=0.000), the prevalence of HUA in occasional smoking group was higher( OR=1.194, 95% CI: 1.013~1.408, P=0.035). Conclusions:As compared with the non-smoking group, the prevalence of HUA is lower in smoking group and is higher in occasional smoking group.
