[Clinical characteristics and related factors of somatization symptoms in outpatients with psychiatric disorders of the department of cardiology in general hospitals].

To explore the clinical characteristics and related factors of somatization symptoms in outpatients with psychiatric disorders of the cardiology department in general hospital. Cross-sectional survey method was used in this study. From August 2017 to September 2018, 508 outpatients of our department with suspected mental disorders, who complained of physical discomfort and screened by the "Three Questions" method recommended by the Chinese Expert Consensus on Psychological Prescriptions of Cardiovascular Patients in 2014, were consecutively included. General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9), Patient Health Questionnaire-15 (PHQ-15) and self-made general demographic questionnaire (including age, sex, marital status, educational level, occupation, duration of disease, clinical diagnosis and the process of medical treatment for the main somatic symptoms in recent one year) were used to investigate these patients, under the assistance of unified training psychological consultants. The detection rate of anxiety and depression, the degree and distribution of somatization symptoms in outpatients with mental disorders were analyzed, and the related factors affecting the occurrence of somatization symptoms were screened by multivariate logistic regression. The selected patients were (51.3±10.1) years old, of which 37.8% (192/508) were males and 62.2% (316/508) were females. The total detection rate of anxiety/depression was 86.8% (441/508), and the detection rate of somatization symptoms was 93.1% (473/508). The number of positive symptom items in PHQ-15 was 8.0±2.7, and the detection rate of anxiety/depression was 78.6% (372/473) in patients with somatization symptoms. There were significant differences in the proportion of women, the average number of outpatient visits and hospitalizations in the past one year, GAD-7 score and PHQ-9 score among the patients with mild, moderate and severe somatization symptoms (all <0.05). PHQ-15 score was positively correlated with GAD-7 score (0.524 5, 0.001) and PHQ-9 score (0.574 9, 0.001) in patients with somatization symptoms. Stepwise logistic regression analysis showed that total scores of PHQ-9 (8.020, 95 3.470-18.930, 0.001) and GAD-7 (6.526, 95 2.903-13.045, 0.001) and female (4.440, 95 1.059-9.073, 0.011) were related factors of somatizations. The incidence of somatization symptoms is high in patients with psychological disorders in outpatients of cardiology department in general hospital. Anxiety, depression and gender are the main related risk factors of somatization symptoms in this patient cohort. Degree of anxiety and depression increased in proportion to the severity of somatization symptoms. Anxiety, depression and female is related to somatization symptoms.
