Psychiatric morbidity in two urban communities in Nigeria

Abstract

Background: There is a welter of evidence for an inverse relationship between socio-economic status (SES) and mental health. The relationship is grossly under researched in the developing countries. Objective: To ascertain rates of gross psychiatric morbidity and some demographic correlations in two communities with different socio-economic standards. Design: A cross-sectional community based study. Subjects: Random samples of two socio-economically dissimilar communities (N1 = 189, N2 = 148) were assessed for psychiatric morbidity. Results: Rates of psychiatric morbidity obtained for the lower status community (Ajegunle) and the higher status community (Victoria Island/Ikoyi) on the GHQ-12 were 26.5 and 14.2 respectively and the corresponding figures on the SRQ (non-psychosis) were 41.8 and 18.2 and on the SRQ (psychosis) 61.5 and 31.7. A large number of positive socio-demographic correlations between cases and non-cases were obtained on SRQ and GHQ-12 in both communities. Family history of psychiatric illness significantly differentiates cases from non-cases on all measures of morbidity. Conclusion: The socio-economic inequality demonstrated should be minimised by evolving a social welfare policy in Nigeria and other developing countries that is responsive to the survival needs of the populace and ensures equitable distribution of resources across socio-economic strata. There is dire need for further research into the complex bearings of the link between social status and psychological wellness in the developing world.
