Psychoanalysis of 300 patients with chronic gastritis

Objective To analyze the difference of psychosocial characteristics in patients with chronic gastritis. Methods From June to December 2018, a total of 300 patients with chronic gastritis visited Xijing Hospital were consecutively enrolled. The patients were divided into chronic non-atrophic gastritis (CNAG) group, chronic atrophic gastritis (CAG) group and CAG with intestinal metaplasia group, with 100 cases in each group. Hamilton anxiety scale (HAMA), Hamilton depression scale (HAMD), living events scale (LES) and Eysenck personality questionnaire (EPQ) were used for evaluation and analysis. Chi square test, analysis of variance, nonparametric rank sum test and Kruskal Wallis H test were used for statistical analysis. Results The incidences of anxiety of the CAG group and the CAG with intestinal metaplasia group were both significantly higher than that of the CNAG group (64.0%, 64/100; 53.0%, 53/100; and 34.0%, 34/100; respectively), and the differences were statistically significant (χ2=0.007 and 0.001, both P 56.7) of etraversion or introversion and concealment in CAG group and the CAG with intestinal metaplasia group were higher than those in the CNAG group (48.0%, 48/100; 23.0%, 23/100; 4.0%, 4/100 and 46.0%, 46/100; 21.0%, 21/100 and 7.0%, 7/100, respectively), and the differences were statistically significant (χ2=0.001, 0.001, 0.001 and 0.004, all P<0.01). Conclusions Anxiety is associated with CAG and intestinal metaplasia, while depression is associated with intestinal metaplasia. In male patients and patients under 50 years old, depression, negative event and high psychiatric stress are more significantly related to intestinal metaplasia. The mental characteristics of extroversion, emotional instability, psychoticism and concealment are closely associated with CAG.
