The purpose was to investigate the prevalence of gastritis and its risk factors in local population. The subjects were selected randomly. Thequestionnaires were filled by them. The questions included the demographical information and contributing factors of gastritis. The result showed that the prevalence of gastritis was 73.5%. Among 294 patients, the prevalence of gastritis in females (65.98%) was higher than in males (34.01%). The mean age of the population was 38.8years ±0.65, the mean height was 160.9cm ±0.74 for females and 163.47 ±0.83 for males, the mean weight was 67.39Kg± 1.0 for females and 69.04 ±1.03 for males and the mean BMI was 25.98Kg/m2 ±0.35 and 25.87Kg/m2 ±0.37 for females and males respectively.
