Prevalence of major depressive disorder in Nigerian college students with alcohol-related problems

ObjectivesThe study aimed to estimate the prevalence of major depressive disorder (MDD) among Nigerian college students with alcohol-related problems (ARP) and compare the estimated prevalence with their counterparts without ARP.MethodA cross-sectional survey of a representative sample of students (n=2658) in six colleges in Osun state, Western Nigeria. The students were independently assessed for ARP and MDD with the Mini International Neuropsychiatric Interview (MINI).ResultsThe current (2 weeks) prevalence of MDD in college students with alcohol dependence is 23.8%; alcohol abuse 17.2% and hazardous use 12.4%. Compared with total abstainers, major depressive disorder is significantly more likely to be associated with diagnosis of alcohol dependence (OR 3.14, 95% CI 1.42–6.96), alcohol abuse (OR 2.27, 95% CI 1.38–3.72) and hazardous use (OR 1.64, 95% CI 1.12–2.38), but less associated with alcohol users without ARP (OR 0.93, 95% CI 0.69–1.25).ConclusionNigerian college students with ARP are significantly more at risk of depressive disorders than those without ARP. Early recognition and treatment of depression are important considerations when planning preventive strategies for alcohol-related problems in college students.
