Abstract
OBJECTIVE: The aim of this study is to examine the distribution and features of gastroscopy in northern Xinjiang, a province in China. METHODS: We included a group of 895 patients diagnosed with digestive diseases at Urumqi Friendship Hospital and analyzed their gastroscopic results and baseline data. RESULTS: Among patients aged 12 to 86 years in the specified region, females exhibited a heightened susceptibility to esophageal-gastrointestinal and intestinal disorders compared to males. The mean age for chronic gastritis onset was determined to be 54.79 years. In the context of esophageal-gastric-intestinal disorders, the distribution across various ethnic groups manifested as follows: the Han, Uygur, Hui, and Kazakh populations comprised 53.97%, 23.91%, 7.15%, and 3.46%, respectively. Through principal component-based dimension reduction analysis, we identified chronic non-atrophic gastritis with erosive gastritis, duodenal bulb inflammation, and chronic non-atrophic gastritis (predominantly in the gastric antrum) as pivotal factors contributing to differences in hiatal hernia. Multiple linear regression models were established for different ethnic groups, duodenal bulb inflammation, and hiatal hernia by age. The results revealed a heightened risk of duodenal bulb inflammation (P < 0.01) in Han, Kazakh, Hui, Mongolian, and Uygur women, while the risk of hiatal hernia exhibited a positive correlation with age (P = 0.001). CONCLUSION: Among patients undergoing gastrointestinal examinations in northern Xinjiang, the most prevalent pathological condition was identified as chronic gastritis. Notably, within this subgroup, the prevalence of duodenal bulb inflammation was found to be greater in women than in men. The ethnic composition within this context encompassed patients from the Han, Kazakh, Hui, and Mongolian ethnic groups. Furthermore, a positive correlation was identified between the incidence of esophageal hiatal hernia and age.
