Background and Aim: It is important to evaluate the coexistence of psychiatric disorders in substance- dependent people in the treatment process of substance abuse and psychiatric disorders. Studies show that substance use is associated with psychiatric disorders. Probably, when two or more substances are consumed at the same time, the prevalence of psychiatric disorders is higher and the related factors are also higher. This research was done due to the knowledge gap in this field.
Methods: In this descriptive study, 224 men between the ages of 18 and 60 with simultaneous use of more than two substances who were referred to the Iran Psychiatric Hospital for treatment in 1401 and 1402 were investigated. Possible related factors such as age, education level, marital status, and the number of substances consumed were investigated. Finally, the prevalence of psychiatric disorders including generalized anxiety disorder, obsessive- compulsive disorder and major depressive disorder in patients was determined. The results were analyzed with SPSS software using T-test and Chi-Square tests.
Results: The average age of the participants was 37.10 ± 9.62 years. The results showed that cannabis (19.1%), clonazepam (13.4%), methamphetamine (12.9%) and opium (12.2%) were the most used substances in the patients. The prevalence of major depressive disorder, generalized anxiety disorder, and obsessive- compulsive disorder in patients was estimated as 39.7% ± 6.5%, 32.6% ± 6.3% and 33.9% ± 6.3%, respectively in 95% CI, and there was no significant difference in their prevalence (P = 0.402). In general, the prevalence of psychiatric disorders was 74.6 ± 5.8% with 46.9% of patients having one psychiatric disorder and 27.7% of them having two or three psychiatric disorders. Also, the results showed that 26.2% of patients used three substances, 5.7% of patients used four substances, and 1.5% of patients used more than four substances. It was observed that with increasing education levels, the prevalence of psychiatric disorders decreased (P < 0.05). However, there was no significant difference in the criteria of age, marital status, and the number of substances consumed in terms of the presence of psychiatric disorders in this sample.
Conclusion: Generalized anxiety disorder, obsessive- compulsive disorder and major depressive disorder are very common among men aged 18 to 60 who use more than two substances at the same time.
