[BDSP. Notice produite par INIST R0xDqEQ3. Diffusion soumise à autorisation]. Several empirical studies have documented the effects of residential segregation on health inequalities between the US African-American and white populations. However, the majority of such studies have not explained the pathways that link residential segregation and specific health outcomes. This paper presents a conceptual framework of the role that residential segregation may play in the epidemiology of tuberculosis (TB) and other infectious diseases. This is an important issue given the concentration of TB cases among US racial/ethnic minorities and the increasing gap in the incidence of infectious diseases between minorities and the white majority. Segregation may have an indirect effect on the transmission of TB because of its negative impact on the quality of neighborhood environment in segregated communities. Segregation concentrates poverty, overcrowded and dilapidated housing and social disintegration in minority areas, and results in limited access to health care. Furthermore, two dimensions of residential segregation (isolation and concentration) may have direct effects on TB transmission. The isolation of minorities confines TB to segregated areas and prevents transmission to the rest of the population. High-density levels in minority areas increase the probability of transmission within the segregated group. (...)
