Intimate connections among race, place, and poverty are increasingly featured in the health disparities literature. However, few models exist that can guide our understanding of these interconnections. We build on the Chicago School of Sociology's contributions in urban research and one of its contemporary elaborations, often described as the "neighborhood effects approach," to propose a three-axis model of health inequity. ⋯ Compositional axes of race and poverty form the foundation of the model. These compositional axes then intersect with a third axis of place to compose the built and social environment planes. We develop this model to provide conceptual guidance for clinical, policy, and public health researchers who aim to examine how these three features, taken together, have important implications for urban health.

In the USA, undocumented Latino immigrants may have poorer health because of barriers to health care, stressors, and detrimental effects of immigration enforcement. Previous immigrant health research, however, suggests that recently arrived Latino immigrants have better health than US-born Latinos and their health deteriorates over time. Given the current environments that undocumented immigrants face, legal status is a structural factor that likely influences the patterns of immigrant health. ⋯ Undocumented immigrants, regardless of duration, had higher blood pressure than documented immigrants who had been in the USA for less time and the same level of blood pressure as the US born. In contrast, shorter duration documented immigrants had lower blood pressure compared to longer duration documented immigrants and US-born counterparts, and marginally lower blood pressure than shorter duration undocumented immigrants. The findings suggest that the "health advantage" generally presumed to exist among immigrants may not affect undocumented immigrants.

We assessed socio-structural and behavioral correlates of preexposure prophylaxis (PrEP) for HIV infection among a sample of high-risk HIV-negative men who have sex with men (MSM) in Los Angeles, California. Participants from an ongoing 5-year prospective cohort study investigating the direct impacts of substance use on HIV transmission dynamics were enrolled between February 2015 and January 2017. All men completed a computer-assisted self-interview every 6 months that assessed recent (past 6 months) PrEP use and socio-structural and behavioral factors. ⋯ Behavioral factors associated with recent PrEP use include sex with a HIV-positive partner (aPR = 3.63, 95% CI 1.45 to 9.10, p = 0.01), having six or more sex partners (aPR = 2.20, 95% CI 1.26 to 3.82, p = <0.01), and popper use (aPR = 2.76, 95% CI 1.58 to 4.84, p = <0.01). In this sample of predominantly racial/ethnic minority MSM, socio-structural and behavioral factors were important factors associated with recent PrEP use. These findings provide considerations for intervention development to promote PrEP use among key groups of MSM.

Black gay, bisexual, and other men who have sex with men (BMSM) experience a disparate rate of HIV infections among MSM. Previous analyses have determined that STI coinfection and undiagnosed HIV infection partly explain the disparity. However, few studies have analyzed the impact of partner-level variables on HIV incidence among BMSM. ⋯ IPV is an important correlate of both HIV prevalence and incidence in BMSM. Further studies should explore how IPV affects HIV risk trajectories among BMSM. Given that individuals with IPV history may struggle to negotiate safer sex, IPV also warrants consideration as a qualifying criterion among BMSM for pre-exposure prophylaxis (PrEP).
