The vast majority of studies investigating participation in, persistence through, and consequences of postsecondary education focus on educational attainment status among the so-called traditional population of collegegoers between the ages of 18 and 24. This narrow focus leaves largely invisible the role that an expanding set of educational trajectories throughout adulthood plays in shaping social stratifcation. Using 35-plus and 20 years of follow-up data from the US National Longitudinal Survey of Youth (NLSY)’s 1979 and 1997 cohorts, we fnd that a substantial share within each cohort is attaining education well into adulthood, and that these trajectories are patterned according to key social and demographic characteristics. In both cohorts, racial/ethnic diferences in educational attainment grew over time and, for those attaining the same degree, members of historically disadvantaged groups did so at an older age. Cohort diferences in trajectories emerged, however, when considering the intersection of race/ethnicity and socialized gender. Through careful descriptive analysis of two generational cohorts, our study makes clear the role of educational trajectories in the process of cumulative (dis)advantage across the life course, as well as across generations.

As medicine integrates social and structural determinants into health care, some health workers redefine housing as medical treatment. This article discusses how health workers in two U.S. urban safety-net hospitals worked with patients without stable housing. We observed ethnographically how health workers helped patients seek housing in a sharply stratified housing economy. Analyzing in-depth interviews and observations, we show how health workers: (1) understood housing as health care and navigated limits of individual care in a structurally produced housing crisis; and (2) developed and enacted practices of biomedical and sociopolitical stabilization, including eligibilizing and data-tracking work. We discuss how health workers bridged individually focused techniques of clinical care with structural critiques of stratified housing economies despite contradictions in this approach. Finally, we analyze the implications of providers’ extension of medical stabilization into social, economic, and political realms, even as they remained caught in the structural dynamics they sought to address.

Health care systems in the United States are experimenting with a form of surveillance and intervention known as “hot spotting,” which targets high-cost patients—the so-called “super-utilizers” of emergency departments—with intensive health and social services. Through a calculative deployment of resources to the costliest patients, health care hot spotting promises to simultaneously improve population health and decrease financial expenditures on health care for impoverished people. Through an ethnographic investigation of hot spotting’s modes of distribution and its workings in the lives of patients and providers, we find that it targets the same individuals and neighborhoods as the police, who maintain longer-standing practices of hot spotting in zones of racialized urban poverty. This has led to a convergence of caring and punitive strategies of governance. The boundaries between them are shifting as a financialized logic of governance has come to dominate both health and criminal justice.

Introduction

Social factors across one’s lifespan may contribute to the relationship between low educational attainment and depression, but this relationship has been understudied. Previous studies assessing the association between educational attainment and depression did not fully account for prior common determinants across the life course and possible interactions by sex or race/ethnicity. It is also unclear whether the link between educational attainment and depression is independent of the role of aspired educational attainment or expected educational attainment.

Methods

We used generalized linear log link models to examine the association between educational attainment at age 25 and depression at age 40 in the National Longitudinal Survey of Youth 1979 cohort, adjusting for confounders and mediators from childhood, adolescence, and adulthood.

Results

Members of each educational attainment group were less likely to be depressed at age 40 than those with less education. After adjusting for educational aspirations and educational expectations, the risk ratios became closer to the null. Neither sex nor race/ethnicity interacted with educational attainment. Additionally, low educational expectations in adolescence, but not low educational aspirations, was associated with a higher risk of depression at age 40.

Conclusion

Our study provides a nuanced understanding of the role of education, educational expectations, and educational aspirations as part of education’s effect on risk of depression after controlling for a thorough set of confounders and mediators. Our findings may help advance the study of social determinants of depression.

Housing status affects drug using behaviors, but less is known about the relationship between housing patterns and hepatitis C virus (HCV) infection. HCV-negative young people who inject drugs (PWID) were enrolled into a prospective cohort (2003-2019) with quarterly study visits. We used Cox regression to estimate the independent association of recent housing status (housed vs. unhoused, housing stability, and housing trajectory) on HCV incidence. Among 712 participants, 245 incident HCV infections occurred over 963.8 person-years (py) (cumulative incidence 24.4/100 py). An inverse relationship between time housed and HCV incidence was observed (always unhoused 45.0/100 py, 95% confidence interval (CI) 37.1, 54.5; variably housed 18.0/100 py, 95% CI 15.0, 21.3; and always housed 7.0/100 py, 95% CI 3.0, 17.3). In Cox regression models controlling for confounders, those unhoused versus housed at baseline had a 1.9-fold increased infection risk (95% CI 1.4, 2.6). Those always unhoused versus always housed had a 1.5 times greater risk of HCV (95% CI 1.0, 2.3), and those spending a portion of time in stable housing a lower risk (adjusted relative hazard 0.05, 95% CI 0.3, 0.9) with a similar trend for those being housed for less time. Young adult PWID experiencing both recent and chronic states of being unhoused are at elevated risk for HCV infection. Importantly for this group of PWID, our findings indicate that some frequency of residential housing significantly reduces HCV infection risk.

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.

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.

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.
