Non-medical prescription opioid use and opioid use disorder in the military population in Nigeria

Objective: Aim of the study was to determine 12-month prevalence of non-medically prescribed opioid use (NMPOU) and NMPOU disorder among a military population in Nigeria. Method: In this descriptive cross sectional study, 224 military officers were interviewed by multistage stratified systematic sampling method. The Composite International Diagnostic Interview (CIDI) version 7.0 was used to generate data on 12-month prevalence of NMPOU and NMPOU disorder. Associated factors and predictors were determined using SPSS Version 17.0, IBM, Chicago, Illinois. Results: Prevalence of NMPOU was 6.7% and NMPOU disorder, 3.6%. Predictors of NMPOU were: 12-month tobacco use, OR = 2.01, 95% CI (1.12-6.42) and 12-month cannabis use disorder OR = 2.96, 95% CI (1.35-7.38), Predictors of 12-month NMPOU disorder were: 12-month alcohol use disorder OR = 1.59, 95% CI (1.13-3.29), 12-month tobacco use disorder OR = 3.94, 95% CI (1.95-5.04) and 12-month cannabis use disorder OR = 3.0, 95% CI (2.06-8.87) Conclusion: NMPOU and NMPOU disorder is a major health issue in the military. This population requires substance use prevention and intervention programs.
