Prevalence and correlates of major depression among Nigerian adults with sickle cell disease

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.
