Factors influencing the higher incidence of tuberculosis among migrants and ethnic minorities in the UK.

Migrants and ethnic minorities in the UK have higher rates of tuberculosis (TB) compared with the general population. Historically, much of the disparity in incidence between UK-born and migrant populations has been attributed to differential pathogen exposure, due to migration from high-incidence regions and the transnational connections maintained with TB endemic countries of birth or ethnic origin. However, focusing solely on exposure fails to address the relatively high rates of progression to active disease observed in some populations of latently infected individuals. A range of factors that disproportionately affect migrants and ethnic minorities, including genetic susceptibility, vitamin D deficiency and co-morbidities such as diabetes mellitus and HIV, also increase vulnerability to infection with Mycobacterium tuberculosis (M.tb) or reactivation of latent infection. Furthermore, ethnic socio-economic disparities and the experience of migration itself may contribute to differences in TB incidence, as well as cultural and structural barriers to accessing healthcare. In this review, we discuss both biological and anthropological influences relating to risk of pathogen exposure, vulnerability to infection or development of active disease, and access to treatment for migrant and ethnic minorities in the UK

Consumer ethnicity three decades after: a TCR agenda

Research into consumer ethnicity is a vital discipline that has substantially evolved in the past three decades. This conceptual article critically reviews its immense literature and examines the extent to which it has provided extensive contributions not only for the understanding of ethnicity in the marketplace but also for personal/collective well-being. We identify two gaps accounting for scant transformative contributions. First, today social transformations and conceptual sophistications require a revised vocabulary to provide adequate interpretive lenses. Second, extant work has mostly addressed the subjective level of ethnic identity projects but left untended the meso/macro forces affecting ethnicity (de)construction and personal/collective well-being. Our contribution stems from filling both gaps and providing a theory of ethnicity (de)construction that includes migrants as well as non-migrants
