Objective To understand the occurrence of somatization disorder and its correlation with anxiety and depression in patients with self-poisoning by pesticides and drugs, and to improve their survival and quality of life.

Methods A total of 220 patients with acute self-poisoning by pesticides and drugs in a comprehensive hospital from February 2019 to June 2020 were studied.The Self-Rating Somatic Symptom (SSS) was used to assess the somatization disorder, and the Generalized Anxiety Disorder Scale (GAD-7) and the Patient Health Questionnaire (PHQ-9) were used to analyze the anxiety and depression.The correlation between them was analyzed.

Results Among the 220 patients, 198(90.0%) had somatization disorder.There were 28 patients (14.1%) with only one somatic symptom, while 35(17.7%), 56(28.3%), and 79(39.9%) patients had two, three, or more than three symptoms, respectively.Among 198 patients with somatization disorder, 120 cases (60.6%) had anxiety symptoms and 108 cases (54.54%) had depression symptoms; 48 patients had both anxiety and depression symptoms, and the overall positive detection rate (the proportion of people diagnosed with either anxiety or depression) was 90.9%.The overall positive rate of either anxiety or depression among females was higher than that of males and the lowest in the married group.The higher the education level, the lower the detection rate (P < 0.05).The Kruskal-Wallis test showed that as the degree of somatization disorder increased, the frequency of moderate anxiety, severe anxiety, depression, or anxiety combined with depression increased accordingly (P < 0.05).

Conclusions Patients with somatization disorder were more likely to have emotional disorders.The awareness of somatic symptoms and psychological disorders in patients with self-poisoning by pesticides and drugs should be strengthened, and timely psychological interventions should be given to reduce the risk of suicide.
