Major mental disorders in Addis Ababa, Ethiopia. II. Affective disorders

This report examines the prevalence and socio‐demographic correlates of affective disorders based on a survey conducted in Addis Ababa between September and December of 1994. An Amharic version of the CIDI was used to collect data from a random community sample of 1420 individuals aged 15 and above. The lifetime prevalence for specific affective disorders was as follows: bipolar disorders 0.3%, depressive episodes 2.7%), recurrent depressive episodes 0.2% and persistent mood disorders 1.6%. The weighted lifetime prevalence of affective disorders was 5.0%) (women 7.7% and men 3.2%). One‐month prevalence was 3.Wo (women 5.9% and men 2.3%). After adjusting for several potential confounders, the risk of affective disorders was only 29% higher in women compared to men. This difference in risk was not statistically significant. Age was also not associated with risk of affective disorders. On the other hand, education was associated with the risk of disorder, the risk decreasing with increasing educational attainment. This inverse trend was statistically significant ( P for trend=0.02). The risk was also 37%1 lower in the employed than the unemployed: Odds Ratio (OR), 95% confidence interval (95% CI) = 0.63 (0.39, 1.01). There were no statistically significant associations between affective disorders and marital status or ethnicity.
