Abstract: Objective To investigate the prevalence of chronic gastritis among physical examinees in Guangxi region and analyze its influencing factors. Methods A questionnaire survey was used to collect the data of the population who underwent physical examination in the physical examination center of a tertiary A hospital in Guangxi Zhuang Autonomous Region from March 2021 to October 2022. According to the Chronic Gastritis Basic Diagnosis and Treatment Guide, patients with dyspepsia such as upper abdominal pain, early satiation, belching, and other dyspepsia and positive Helicobacter pylori （Hp） were further examined by gastroscopy to complete the diagnosis process of chronic gastritis. Descriptive analysis method was used to analyze the prevalence of chronic gastritis among the physical examinees, and univariate and multivariate analysis methods were used to analyze the influencing factors of chronic gastritis. Results A total of 3 255 physical examinees were included in this study, including 1 717 males and 1 538 females, aged 22-68 years, with an average age of （50.12±13.32） years. Among them, 787 cases were diagnosed with chronic gastritis, with a prevalence of 24.18%. The results of multivariate logistic regression analysis showed that smoking （OR=2.428）, drinking （OR=1.973）, Hp infection （OR=2.150）, excessive salt intake （OR=2.891）, regular diet （OR=0.525）, and overeating （OR=2.331） were the influencing factors of chronic gastritis among the physical examinees. Conclusions The prevalence rate of chronic gastritis is higher among the physical examinees in Guangxi region. The influencing factors of chronic gastritis in this population are similar to other populations in China, and these factors should be paid attention to in practice.
