Prevalence of alcohol and other psychoactive substance abuse and association with depression among medical students in Niger Delta University, Bayelsa State.

Introduction: alcohol and other psychoactive substances have adverse health effects, particularly on young people. This study determined the prevalence of alcohol and other psychoactive substance abuse and its association with depression among Niger Delta University, Bayelsa State, Nigeria, medical students.
Methods: a cross-sectional study involving 243 medical students who completed a patient-rated version of the Mini International Neuropsychiatric Interview (MINI-PR). For analyzing the data, descriptive and inferential statistics were employed.
Results: most respondents were 18 to 24 years old (67.1%), and 52.7% were male; the prevalence of major depressive episodes (current) and lifetime alcohol and other psychoactive use was 30.5%, 25.5%, and 21%, respectively. Also, the prevalence of current alcohol abuse and dependence was 5.8% and 4.9%, respectively. Alcohol use (χ ² : 12.57, p = 0.001) and abuse (χ ² : 22.33, p = 0.001) were significantly associated with depression. Psychoactive substance use was significantly associated with depression (χ ² : 12.91, p = 0.001). The odds of having depression increased with the use of alcohol (OR: 3.54; 95% CI: 1.71-7.33) and psychoactive substances (OR: 4.52; 95% CI: 1.88-10.88).
Conclusion: alcohol and psychoactive substance use were significantly associated with depression. Organizing interventions to reduce such unhealthy social practices among medical students is necessary.
