    Impact of common mental disorders during childhood and adolescence on secondary school completion
    (2009) Myer, Landon; Stein, Dan J; Jackson, Pamela B; Herman, Allen A; Seedat, Soraya; Williams, David R
    There are few data from South Africa and other low- and middle-income countries on how mental disorders in childhood and adolescence may influence different aspects of socio-economic position, including educational attainment. We examined the association between early-onset disorders and subsequent educational achievement in a nationally representative sample of 4 351 South African adults. After adjusting for participant demographic characteristics and traumatic life events, post-traumatic stress disorder, major depressive disorder and substance-related disorders were each associated with increased odds of failing to complete secondary education (odds ratios and 95% confidence intervals 2.3, 1.0 - 5.1; 1.7, 1.2 - 2.5, and 1.7, 1.2 - 2.5, respectively). These data point to the role that early-life mental disorders may play in educational achievement and subsequent socio-economic position over the life course.

    Life stress and mental disorders in the South African stress and health study
    (2009) Seedat, Soraya; Stein, Dan J; Jackson, Pamela B; Heeringa, Steven G; Williams, David R; Myer, Landon
    Background. Although stressful life events (SLEs) are associated with psychopathology, the contribution from distal and proximal events and the specificity of their association with common mental disorders require further exploration. We examined the association of recent life events and past adversities to mood, anxiety, substance use and impulse control disorders in South Africa. Methods. Data were analysed from the South African Stress and Health study, a population-based study of mental disorders in a nationally representative sample of 4 351 adults. Psychiatric disorders were assessed with the Composite International Diagnostic Interview (CIDI). This included questions covering early and later SLEs (negative life events, relationship stress, partner violence, social strain and adverse events during childhood) and various sociodemographic variables. Logistic regression models were constructed for 3 957 respondents (2 371 female, 1 586 male) with no missing covariate data, to assess life stress and sociodemographic predictors of 12-month and lifetime disorder. Results. Recent negative life events and relationship problems were significant predictors of any 12-month disorder and any lifetime disorder. Physical partner violence predicted any lifetime disorder. There was evidence of specificity for the prediction of mood versus anxiety disorders, with childhood adversity specifically associated with mood disorders but not anxiety disorders. Single marital status was the strongest socio-demographic predictor of any 12-month and any lifetime disorder. Conclusions. Stressful life events, distal and proximal, contribute significantly and independently to the prediction of major psychiatric disorders among South Africans, underscoring the importance of screening adversities in adults with common mental disorders, and of providing appropriate adjunctive interventions.

    Perceived discrimination and mental health disorders: the South African Stress and Health study
    (2009) Moomal, Hashim; Jackson, Pamela B; Stein, Dan J; Herman, Allen; Myer, Landon; Seedat, Soraya; Madela-Mntla, Edith; Williams, D R
    Objectives. To describe the demographic correlates of perceived discrimination and explore the association between perceived discrimination and psychiatric disorders. Design. A national household survey was conducted between 2002 and 2004 using the World Health Organization Composite International Diagnostic Interview (CIDI) to generate diagnoses of psychiatric disorders. Additional instruments provided data on perceived discrimination and related variables. Setting. A nationally representative sample of adults in South Africa. Subjects. 4 351 individuals aged 18 years and older. Outcomes. 12-month and lifetime mood, anxiety and substance use disorders. Results. In the multivariate analyses, acute and chronic racial discrimination were associated with an elevated risk of any 12-month DSM-IV disorder when adjusted for socio-demographic factors, but this association was no longer statistically significant when adjusted for other sources of social stress. In fully adjusted models, acute racial discrimination was associated with an elevated risk of lifetime substance use disorders. Acute and chronic nonracial discrimination were associated with an elevated risk of 12-month and lifetime rates of any disorder, even after adjustment for other stressors and potentially confounding psychological factors. The association of chronic non-racial discrimination and 12-month and lifetime disorder was evident across mood, anxiety, and substance use disorders in the fully adjusted models. Conclusion. The risk of psychiatric disorders is elevated among persons who report experiences of discrimination. These associations are more robust for chronic than for acute discrimination and for non-racial than for racial discrimination. Perceived discrimination constitutes an important stressor that should be taken into account in the aetiology of psychiatric disorders.
