Objectives: Pesticide poisoning is a common method of suicide in Taiwan. In this study, we intended to study patients’ underlying psychiatric diagnoses and gender differences. Methods: We conducted a retrospective observational study on inpatients who had suicide attempts with pesticide-poisoning from 2000 to 2011. The patients were referred to the psychiatric consultation staff, and their diagnoses were made according to DSM-IV. Patients’ demographic and clinical variables, psychiatric diagnoses, and concurrent life stress were obtained and analyzed. Results: Among 177 patients, the majority (77%) of the patients with attempted suicide used organophosphate poisoning. The most frequent diagnoses were depressive disorders (58%), substance use disorders (35%), and adjustment disorder (28%). The male-to-female gender ratio was 2. The male patients had significantly more substance use disorder, particularly alcohol use disorder, than female counterparts (p < 0.01). Patients’ major life stressors were illness, couple conflicts, layoff from jobs, parent-child conflict, and economic stress. Among concurrent life stressors, male patients had significantly more layoff reasons than female patients (p < 0.05). Female patients had significantly more often couple conflicts than male patients (p < 0.05). Conclusion: Patients’ gender differences existed in attempted suicide with pesticide poisoning, in demographic profiles and psychiatric diagnoses. Suicide risk assessment and prevention should therefore be considered the patients’ factor of gender.
