Abstract BACKGROUND: Large-scale community studies of the prevalence of mental disorders using standardised assessment tools are rare in sub-Saharan Africa. AIMS: To conduct such a study. METHOD: Multistage stratified clustered sampling of households in the Yoruba-speaking parts of Nigeria. Face-to-face interviews used the World Mental Health version of the Composite International Diagnostic Interview (WMH-CIDI). RESULTS: Of the 4984 people interviewed (response rate 79.9\%), 12.1\% had a lifetime rate of at least one DSM-IV disorder and 5.8\% had 12-month disorders. Anxiety disorders were the most common (5.7\% lifetime, 4.1\% 12-month rates) but virtually no generalised anxiety or post-traumatic stress disorder were identified. Of the 23\% who had seriously disabling disorders, only about 8\% had received treatment in the preceding 12 months. Treatment was mostly provided by general medical practitioners; only a few were treated by alternative practitioners such as traditional healers. CONCLUSIONS: The observed low rates seem to reflect demographic and ascertainment factors. There was a large burden of unmet need for care among people with serious disorders.
