An In-Depth Investigation into the Co-Occurrence of Substance Use in Individuals with Alcohol Use Disorder and its Association with Sociodemographic Factors

Background: Alcohol Use Disorder (AUD) presents a significant global public health challenge, often accompanied by comorbid substance use, complicating treatment. Understanding the prevalence, patterns, and sociodemographic correlates of dual substance use is crucial for effective intervention. Method: This cross-sectional study examined substance use co-occurrence among individuals diagnosed with AUD. Recruitment occurred through addiction treatment centers and psychiatry outpatient departments. Structured interviews, DSM-5 assessments, and sociodemographic questionnaires were conducted. Statistical analyses explored associations between substance use and sociodemographic factors. Result: Tobacco and cannabis showed significant associations with AUD, while opioids, cocaine, and benzodiazepine use exhibited elevated but non-significant associations. Notably, tobacco and benzodiazepine use correlated positively with AUD, indicating potential co-occurrence. Similarly, cannabis and opioids displayed a positive correlation. Conclusion: The study underscores the importance of addressing comorbid substance use in AUD treatment. Findings suggest robust associations between tobacco, cannabis, and AUD, indicating potential co-use patterns. Sociodemographic factors like age, gender, and marital status also influence substance use behaviors, emphasizing the need for tailored interventions.
