The cross-sectional study was Implemented among 1910 adults with over 30 years old at four rural communes of Thai Blnh Province to Identify percentage of hyperuricemia. The results showed that the average serum uric acid concentration was 280.9 umol/L, which was significant higher in men than In women with p value less than 0.001 (316.1 umol/L versus 247.1 umol/L, respectively). The percentage of hyperuricemia was 9.2 percent, which was higher 12 percent in men (at cut-off value of 420 umol/L) than 6.5 percent in women (at cut-off value 360 jJmol/l) with p value less than 0.001. There were increasing of hyperuricemia percentages by age group with p value less than 0.001. The hyperuricemia percentage of overweight and obese group was 23 percent, which was higher than that in the group of normal BMI (9.2 percent) and underweight group (1.7 percent) with p value less than 0.05. The hyperuricemia percentage was higher in the group with hypertention than in the group without hypertention with p value less than 0.001 (12.1 percent and 16,4 percent versus 5.6 percent, respectively). Conclusion: The average serum uric acid was higher in men than in women and increasing by age, gender, BMI and hypertention.
