Background: Chronic atrophic gastritis, incomplete intestinal metaplasia, mucosal dysplasia and Helicobacter pylori infection are mucosal lesions that lead to precancerous gastric lesions. Previous studies showed that poor lifestyles could also lead to precancerous gastric lesions, such as poor diet, drugs misuse, smoking and alcohol drinking. Gastric cancer is one of the top ten cancer lead to death, particularly ranking top three in the world. Due to the high mortality rate of gastric cancer, the governments are incorporation with institutions of medical, health and community to promote stomach cancer prevention. Early prevention is better than disease treatments and should focus on decreasing risk factors of gastric cancer. Objective: The aims of the present study were to examine the relationships between lifestyle and gastritis in middle-old and old age people. Methods: A cross-sectional and secondary data analyses were conducted in this study. Data source was collected from annual health screening questionnaire in a County. The population covered 3,302 people aged 50-70 years with Helicobacter pylori-positive by stool antigen test in the year of 2013-2014. Finally, exclude 895 people without making gastroscopy to follow up; the final sample of the study was 2,460 participants. Result: People's BMI score has a correlation with gastritis prevalence. Variables of gender, age, education level, township of the participants were no significant differences. Alcohol drinking 5 or more units have a higher risk to get gastritis (OR=2.97). Conclusions: Although the present study does not find significant risks in lifestyle toward gastritis, however, the health check-up still identifies high prevalent gastritis in the population and it is an effective policy to prevent further negative consequences.
