RESUMEN

BACKGROUND: Although stressful life events (SLEs) and depression are associated, we do not know if the intersection of race and gender modifies the magnitude of this link. Using a nationally representative sample of adults in the USA, we tested if the association between SLE and major depressive episode (MDE) depends on the intersection of race and gender. METHODS: Data came from the National Survey of American Life (NSAL), 2003, a cross-sectional survey that enrolled 5899 adults including 5008 Blacks (African-Americans or Caribbean Blacks), and 891 Non-Hispanic Whites. Logistic regression was used for data analysis. Stressful life events (past 30 days) was the independent variable, 12-month MDE was the dependent variable, and age, educational level, marital status, employment, and region of country were controls. RESULTS: In the pooled sample, SLE was associated with MDE above and beyond all covariates, without the SLE × race interaction term being significant. Among men, the SLE × race interaction was significant, suggesting a stronger association between SLE and MDE among White men compared to Black men. Such interaction between SLE × race could not be found among women. CONCLUSIONS: The association between SLE and depression may be stronger for White men than Black men; however, this link does not differ between White and Black women. More research is needed to better understand the mechanism behind race by gender variation in the stress-depression link.

RESUMEN

BACKGROUND: Hopelessness is a core component of depression. Our information is, however, very limited on ethnic variations in the magnitude of the link between depression and hopelessness. Using a national sample of older adults in United States, we compared Blacks and Whites for the magnitude of the association between depressive symptoms and hopelessness. METHODS: With a cross-sectional design, we used baseline data of the Religion, Aging, and Health Survey, 2001. Linear regression models were used for data analysis. Depressive symptoms (CES-D) and hopelessness were conceptualized as independent and dependent variables in different models, respectively. Demographic factors (age and gender), socioeconomic status (education and marital status), and health (self-rated health) were covariates. Ethnicity was the moderator. RESULTS: In the pooled sample, higher depressive symptoms were predictive of hopelessness, above and beyond all covariates. We also found significant interactions suggesting that the association between depressive symptoms and hopelessness is weaker among Blacks compared to Whites. In ethnic-specific models, there were significant associations between depressive symptoms and hopelessness among Whites but not Blacks. CONCLUSION: Depressive symptoms accompany more hopelessness among Whites than Blacks. This finding may explain why Blacks with depression have a lower tendency to commit suicide. Future research should test whether or not Whites with depression better respond to psychotherapies and cognitive behavioral therapies that focus on hope enhancement. This finding may explain differential correlates of depression based on race and ethnicity.

RESUMEN

The burden of HIV infection among the nomadic Fulani of northern Nigeria is unknown. Migration - a way of life for this population - is known to increase the rate of HIV transmission and may limit individuals' access to treatment and care. Many of Africa's other traditional, pastoral societies are similarly affected. This paper explores cultural practices and factors among the Fulani that may influence HIV transmission, vulnerability to infection, sustainability and challenges to treatment access, and avenues and models for outreach services; lastly, we proffer some solutions and recommendations. An extensive literature search with cross-referencing was done, and relevant publications on similar themes were reviewed. Three cases of Fulani nomads with HIV are presented to illustrate the challenge of providing a care continuum as well as to demonstrate successes when appropriate HIV interventions are employed. Patient interviews provide valuable insight and information on living and coping with HIV. Community mobility limits opportunities for counselling, testing and diagnosis, as well as HIV-related care access and maintenance. Consanguinity and certain cultural practices among the Fulani have clear amplification potential for HIV transmission. Treatment support through the use of coaches and life partners improves adherence to antiretroviral therapy (ART). Existing programmes for nomads afford opportunities for absorption and integration of HIV services. Nomadic communities should be provided with basic HIV-related services, including risk-reduction education and methods, counselling and testing, ART, medication adherence counselling, access to laboratory tests and health monitoring. These services should be taken to nomadic communities using novel approaches such as mobile units, extension services, case management, directly observed care, and treatment supporters linked to neighbouring health facilities in a hub-and-spoke model. Stronger collaborations are recommended between programmes for nomads and HIV services, and also between veterinary and public health services. Community participation and leadership should be encouraged to ensure the sustainability of HIV-related care delivery. More research is needed on the epidemiology and sociology of HIV infection and the best ways to provide services to hard-to-reach nomadic populations.
