Prevalence of lifetime DSM-IV affective disorders among older African Americans, Black Caribbeans, Latinos, Asians and non-Hispanic White people.

Abstract

The purpose of this study is to estimate lifetime prevalence of seven psychiatric affective disorders for older non-Hispanic White people, African Americans, Caribbean Black people, Latinos, and Asian Americans and examine demographic, socioeconomic, and immigration correlates of those disorders.
Data are taken from the older sub-sample of the Collaborative Psychiatric Epidemiology Surveys. Selected measures of lifetime DSM-IV psychiatric disorders were examined (i.e., panic disorder, agoraphobia, social phobia, generalized anxiety disorder, post-traumatic stress disorder, major depressive disorder, and dysthymia).
Community epidemiologic survey.
Nationally representative sample of adults 55 years and older (n = 3046).
Disorders were assessed using the DSM-IV World Mental Health Composite International Diagnostic Interview.
Major depressive disorder and social phobia were the two most prevalent disorders among the seven psychiatric conditions. Overall, non-Hispanic White people and Latinos consistently had higher prevalence rates of disorders, African Americans had lower prevalence of major depression and dysthymia, and Asian Americans were typically less likely to report affective disorders than those of their counterparts. There is variation across groups in the association of demographic, socioeconomic, and immigration variables with disorders.
This study furthers our understanding of the racial and ethnic differences in the prevalence of DSM-IV disorders among older adults and the correlates of those disorders. It highlights the importance of examining both between-group and within-group differences in disorders and the complexity of the mechanisms associated with differences across groups. Findings from this study underscore the need for future research that more clearly delineates subgroup differences and similarities.
