The contribution of medical mistrust to healthcare utilization delays has gained increased public health attention. However, few studies examine these associations among African-American men, who delay preventive healthcare more often and report higher levels of medical mistrust than non-Hispanic White men. Additionally, studies rarely account for other factors reportedly working in tandem with medical mistrust to increase African-American men’s preventive health screening delays (i.e., everyday racism and perceived racism in healthcare). We examined associations between medical mistrust, perceived racism in healthcare, everyday racism, and preventive health screening delays. Analyses were conducted using cross-sectional data from 610 African-American men aged 20 years and older recruited primarily from barbershops in four US regions (2003–2009). Independent variables were medical mistrust (MM), everyday racism (ER), and perceived racism in healthcare (PRH). Dependent variables were self-reported routine checkup, blood pressure screening, and cholesterol screening delays. Using multiple logistic regression and tests for mediation, we calculated odds ratios and 95% confidence intervals to assess associations between the independent and dependent variables. After final adjustment, African-American men with higher MM were significantly more likely to delay blood pressure screenings. Men with more frequent ER exposure were significantly more likely to delay routine checkups and blood pressure screenings. Higher levels of PRH were associated with a significant increased likelihood of delaying cholesterol screening. MM did not mediate associations between ER and screening delays. Increasing preventive health screening among African-American men requires addressing medical mistrust and racism in and outside healthcare institutions.

Hospitals throughout the United States are implementing new forms of care delivery meant to address social needs for structurally vulnerable patients as a strategy to prevent emergency department visits and hospitalizations and to thereby reduce costs. This article examines how the deployment of social assistance within a neoliberal institutional logic involves the negotiation and alignment of economistic values with ethics of care. We focus on care practices meant to stabilize the socioeconomic conditions of the most expensive patients in the health care system-the "super-utilizers"-through the provisioning of basic resources such as housing, food, transportation, and social support. These patients typically suffer from multiple chronic illnesses accompanied by conditions of poverty, housing and food insecurity, exposure to violence and trauma, and associated substance use and mental health problems. We offer an account of how practices of social assistance are being forged within contexts defined by neoliberal governance.

Our paper explores how legal status stratification shapes the health and health care of low-income patients with chronic illnesses in the U.S. healthcare safety net. Drawing on data from over two years of ethnographic fieldwork at urban safety-net clinics, we examine efforts by Complex Care Management (CCM) teams to stabilize patients with uncontrolled chronic illnesses through primary care-integrated support. We show that stratified citizenship and geographic variability correspond to different possibilities for health care. We suggest an approach to immigration as a structural determinant of health that accounts for the complex, stratified, and changing nature of citizenship status. We also highlight how geographical differences and interactions among local, state, and federal policies support the notion that citizenship is stratified across multiple tiers with distinctive possibilities and constraints for health. While county-based health plans at each of the study sites include residents with varying legal status, lack of formal legal status remains a substantial obstacle to care. Many immigrants are unable to take full advantage of primary and specialty care, resulting in unnecessary morbidity and mortality. In some cases, patients have returned to their country of origin to die. While CCM teams provide an impressive level of support to assist immigrant patients in navigating healthcare and immigration bureaucracies, legal and geographic stratification limit their ability to address broader aspects of these patients’ social context.

In this article, we share our mixed-methods community-engaged approach to study the association between public housing renovation funded through the Rental Assistance Demonstration (RAD) program and the health status and outcomes of the residents living in RAD developments. RAD addresses the nationwide backlog of deferred maintenance at public housing properties. Using address-based queries of electronic health records from 2006–2019, this study will measure the healthcare utilization and clinical health status of residents living in RAD sites pre and post renovation and compare them with nonpublic housing residents living in proximity to RAD developments over the same time period. Applying the principles of community-engaged research, we use in-depth interviews to explore the lived experience of renovation and its impacts on residents’ health and how policymakers and housing developers factor considerations of resident health into their decisions around renovation and redevelopment. Using a prospective, mixed-methods approach that captures both clinical and experiential data will bring into clearer focus the actual health burdens that public housing residents bear, and the health benefits that investment in public housing renovation may bring.

Gentrification may play an important role in influencing health outcomes, but few studies have examined these associations. One major barrier to producing empirical evidence to establish this link is that there is little consensus on how to measure gentrification. To address this barrier, we compared three gentrification classification methodologies in relation to their ability to identify neighborhood gentrification in nine San Francisco Bay Area counties: the Freeman method, the Landis method, and the Urban Displacement Project (UDP) Regional Early Warning System. In the 1580 census tracts, 43% of the population had a bachelor’s degree or higher. The average median household income was $79,671 in 2013. A comparison of gentrification methodologies revealed that the Landis and Freeman methodologies characterized the vast majority of census tracts as stable, and only 5.2% and 6.1% of tracts as gentrifying. UDP characterized 46.7% of tracts at risk, undergoing, or experiencing advanced stages of gentrification and displacement. There was substantial variation in the geographic location of tracts identified as gentrifying across methods. Given the variation in characterizations of gentrification across measures, studies evaluating associations between gentrification and health should consider using multiple measures of gentrification to examine the robustness of the study findings across measures.

Purpose: Evidence suggests education is an important life course determinant of health, but few studies examine differential returns to education by sociodemographic subgroup.

Methods: Using National Longitudinal Survey of Youth 1979 (n = 6158) cohort data, we evaluate education attained by age 25 years and physical health (PCS) and mental health component summary scores (MCS) at age 50 years. Race / ethnicity, sex, geography, immigration status, and childhood socioeconomic status (cSES) were evaluated as effect modifiers in birth year adjusted linear regression models.

Results: The association between education and PCS was large among high cSES respondents (β = 0.81 per year of education, 95% CI: 0.67, 0.94), and larger among low cSES respondents (interaction β = 0.39, 95% CI: 0.06, 0.72). The association between education and MCS was imprecisely estimated among White men (β = 0.44; 95% CI: −0.03, 0.90), while, Black women benefited more from each year of education (interaction β = 0.91; 95% CI: 0.19, 1.64). Similarly, compared to socially advantaged groups, low cSES Blacks, and low and high cSES women benefited more from each year of education, while immigrants benefited less from each year of education.

Conclusions: If causal, increases in educational attainment may reduce some social inequities in health.

Purpose: To examine whether food insecurity longitudinally affects smoking status. Design: Population-based prospective study Setting: Data from the 2003 and 2015 Panel Study of Income Dynamics (PSID). Participants: Four thousand five hundred sixty-three adults who were smokers and nonsmokers, participating in the 2003 (current study baseline) and 2015 (current study follow-up) waves of PSID. Measures: Based on self-reported smoking status at baseline and follow-up, respondents were categorized as continued smoking, stopped smoking, started smoking, and continued nonsmoking. Similarly, respondents were categorized as stayed food secure, stayed food insecure, became food insecure, and became food secure based on responses to the Food Security Survey at baseline and follow-up. Analysis: Two logistic regression analyses to examine (1) among smokers at baseline the odds of stopping versus continuing smoking by follow-up and (2) among nonsmokers at baseline the odds of starting versus continuing nonsmoking by follow-up. In both models, change in food insecurity status was the primary independent variable, controlling for demographics including poverty. Results: Among smokers at baseline, becoming food insecure (vs staying food secure) was independently associated with lower likelihood of stopping smoking by follow-up (odds ratio [OR] ¼ 0.66). Among nonsmokers at baseline, becoming food insecure (vs staying food secure) was independently associated with higher likelihood of starting smoking by follow-up (OR ¼ 3.77). Conclusions: Food insecurity is a risk factor for smoking, which has significant implications for developing interventions to reduce smoking prevalence, especially among low-income groups.

Objectives: The objective was to determine whether children surviving to hospital discharge after firearm assault (FA) and nonfirearm assault (NFA) are at increased risk of mortality relative to survivors of unintentional trauma (UT). Secondarily, the objective was to elucidate the factors associated with long-term mortality after pediatric trauma. Methods: This was a multicenter, retrospective cohort study of pediatric patients aged 0 to 16 years who presented to the three trauma centers in San Francisco and Alameda counties, California, between January 2000 and December 2009 after 1) FA, 2) NFA, and 3) UT. The Social Security Death Master File and the California Department of Public Health Vital Statistics (2000–2014) were queried through December 31, 2014, to identify those who died after surviving their initial hospitalization and to delineate cause of death. Multivariate Cox proportional hazards regression was performed to determine associations between exposure to assault and long-term mortality.

Background: Neighborhood context plays a role in binge drinking, a behavior with major health and economic costs. Gentrification, the influx of capital and residents of higher socioeconomic status into historically-disinvested neighborhoods, is a growing trend with the potential to place urban communities under social and financial pressure. Hypothesizing that these pressures and other community changes resulting from gentrification could be tied to excessive alcohol consumption, we examined the relationship between gentrification and binge drinking in California neighborhoods.
