Abstract: Objective To investigate the related factors of serum uric acid level in physical examinees in Chongqing City in 2019, so as to provide reference for preventing the increase in serum uric acid level. 
Methods People who underwent  physical examination in Department of Physical Examination of our hospital from January 2019 to June 2019 were enrolled as research subjects, and questionnaires were conducted to investigate the related influencing factors of the serum uric acid level in the population. 
Results The Chi-square test results showed that there were statistically significant differences in the detection rates of hyperuricemia between different genders and among different age groups. The t test results showed that as compared with the group with normal blood uric acid level, the group with increased blood uric acid had higher blood uric acid level, higher systolic blood pressure, higher diastolic blood pressure, higher BMI, higher triglyceride, lower HDL cholesterol, increased white blood cell(WBC) count, increased red blood cell(RBC) count and increased hemoglobin. The results of binary Logistic regression analysis showed that smoking, consumption of alcohol, tea, coffee and drinking less than 1 500 mL of water each day and preference for meat were risk factors for increased serum uric acid(OR＜1), while milk intake more than or equal to 3 times a week and seafood intake less than 3 times a week were protective factors for increased serum uric acid(OR＞1). 
Conclusion The increaed blood uric acid level is associated with increased blood pressure, increased WBC count, increased RBC count, and increased triglyceride level. The goal of reducing serum uric acid levels can be achieved by quitting smoking, quitting alcohol, no tea consumption, no coffee consumption and consumption of more water, more milk and less seafood.
