Objective To ascertain the current and lifetime prevalence of depression among adults with sickle cell disease and identify relevant socio-demographic and clinical correlates. Method A cross-sectional study of 205 stable adult out-patient attendees at a treatment center in southern Nigeria between April and September, 2014. A socio-demographic questionnaire, the depression module of Mini International Neuropsychiatric Interview, and the eight-item Morisky Medication Adherence Scale were administered. Categorical and continuous variables associated with a diagnosis of depression were tested using chi-squared and t-tests respectively. Level of significance was set a priori at P < 0.05. Results Prevalence of current depression was 16.6%, while lifetime prevalence was 29.8%. Current depression was significantly associated with frequent analgesic use ( P < 0.03), unemployment ( P = 0.04), low income ( P < .04), low educational status ( P < 0.01), and subjective pain ( P < 0.001). Subjective pain was nearly twice as likely to predict a current depressive episode (AOR: 1.81, 95%CI: 1.42-2.02, P < 0.03). Conclusions Depression is common among adults with sickle cell disease and is significantly associated with severity of subjective pain.
