Residential Eviction and Risk of Detectable Plasma HIV-1 RNA Viral Load Among HIV-Positive People Who Use Drugs

Foreclosure, memory decline, and dementia probability: A longitudinal cohort study

INTRODUCTION

Housing insecurity is rising among older adults; health researchers know little about how this may impact their cognitive health. We investigated links between foreclosure and older adults' memory and probability of dementia.

METHODS

Using the Health and Retirement Study (2008 to 2018), we fit mixed models comparing the memory and dementia probability scores of 249 older adults who experienced foreclosure (treated) with 15,645 who did not. Baseline covariates included sociodemographics, health, and cognition. Models were stratified by age group.

RESULTS

Foreclosure was associated with faster memory decline among middle-aged (50 to 64) older adults (-0.007 standard deviations/year, 95% confidence interval: -0.13, -0.001). Compared to average memory decline among middle-aged older adults who were stably housed, foreclosure equated to 3.7 additional years of aging over 10 years. Among those 65+, differences between those who were and were not foreclosed upon were short-lived and less clear, potentially driven by depletion-of-susceptibles bias.

DISCUSSION

Foreclosure may endanger older adults' memory.

HIGHLIGHTS

Housing instability is a key determinant of cognitive aging. We examined foreclosure and levels and changes in memory and dementia probability scores in the US older adult population. Foreclosure was associated with faster memory decline among middle-aged (50 to 64) older adults, equivalent to 3.7 additional years of cognitive aging over 10 years. Foreclosure yielded sharp memory declines and increases in dementia probability among older adults 65 and above. Foreclosure imposes a greater risk for older adults' cognitive decline.

Eviction as a community health exposure

Evidence suggests that being evicted harms health. Largely ignored in the existing literature is the possibility that evictions exert community-level health effects, affecting evicted individuals' social networks and shaping broader community conditions. In this narrative review, we summarize evidence and lay out a theoretical model for eviction as a community health exposure, mediated through four paths: 1) shifting ecologies of infectious disease and health behaviors, 2) disruption of neighborhood social cohesion, 3) strain on social networks, and 4) increasing salience of eviction risk. We describe methods for parsing eviction's individual and contextual effects and discuss implications for causal inference. We conclude by addressing eviction's potentially multilevel consequences for policy advocacy and cost-benefit analyses.

Treatment with Antiviral Drugs Will Significantly Inhibit the HIV-1 RNA POL Gene Expression and Viral Load in AIDS Patients

Objective

This study is to investigate the difference in HIV-1 RNA pol gene expression in AIDS patients before and after antiviral treatment and its effect on the expression level of CD4+/CD8+ T cells in peripheral blood.

Methods

The participants included 200 AIDS patients who had undergone antiviral medication, and the quantity of HIV-1 RNA pol gene was determined using nested polymerase chain reaction (nPCR). The levels of CD3+, CD4+, and CD8+ T lymphocytes in peripheral blood were measured by flow cytometry before and after therapy. The receiver operating characteristics (ROC) curve was used to assess the impact of HIV-1 RNA pol gene expression and the CD4+/CD8+ ratio on the prognosis of AIDS patients.

Results

After three months of therapy, the levels of HIV-1 RNA and viral load in the patients showed a drastic decline, while the levels of CD4+/CD8+ were markedly elevated (P < 0.05). Logistic analysis revealed that patients' viral loads were positively correlated with HIV-1 RNA and negatively correlated with CD4+/CD8+ (P < 0.05). The alanine aminotransferase (ALT), white blood cell (WBC) count, Serum creatinine (Cr), total cholesterol (TC), triglyceride (TG), and platelet (PLT) levels significantly increased following a 24-month therapy, while no significant changes were observed in the level of aspartate aminotransferase (AST), red blood cell (RBC), and neutrophil (NEU) (%). (P > 0.05).

Conclusion

Antiviral drugs significantly inhibit the HIV-1 RNA POL gene expression and viral load in AIDS patients but upregulate the expression level of CD4+/CD8+ T cells in peripheral blood.

Eviction, Healthcare Utilization, and Disenrollment Among New York City Medicaid Patients

INTRODUCTION

Although growing evidence links residential evictions to health, little work has examined connections between eviction and healthcare utilization or access. In this study, eviction records are linked to Medicaid claims to estimate short-term associations between eviction and healthcare utilization, as well as Medicaid disenrollment.

METHODS

New York City eviction records from 2017 were linked to New York State Medicaid claims, with 1,300 evicted patients matched to 261,855 non-evicted patients with similar past healthcare utilization, demographics, and neighborhoods. Outcomes included patients' number of acute and ambulatory care visits, healthcare spending, Medicaid disenrollment, and pharmaceutical prescription fills during 6 months of follow-up. Coarsened exact matching was used to strengthen causal inference in observational data. Weighted generalized linear models were then fit, including censoring weights. Analyses were conducted in 2019-2021.

RESULTS

Eviction was associated with 63% higher odds of losing Medicaid coverage (95% CI=1.38, 1.92, p<0.001), fewer pharmaceutical prescription fills (incidence rate ratio=0.68, 95% CI=0.52, 0.88, p=0.004), and lower odds of generating any healthcare spending (OR=0.72, 95% CI=0.61, 0.85, p<0.001). However, among patients who generated any spending, average spending was 20% higher for those evicted (95% CI=1.03, 1.40, p=0.017), such that evicted patients generated more spending on balance. Marginally significant estimates suggested associations with increased acute, and decreased ambulatory, care visits.

CONCLUSIONS

Results suggest that eviction drives increased healthcare spending while disrupting healthcare access. Given previous research that Medicaid expansion lowered eviction rates, eviction and Medicaid disenrollment may operate cyclically, accumulating disadvantage. Preventing evictions may improve access to care and lower Medicaid costs.

'That house was a home': Qualitative evidence from New Zealand on the connections between rental housing eviction and poor health outcomes

ISSUE ADDRESSED

Eviction, or a forced move from rental housing, is a common experience for New Zealand renters, yet we know very little about its effects. This research investigated how eviction affects people's lives and health.

METHODS

We conducted semi-structured interviews with 27 people who had experienced eviction. We coded the transcripts and grouped them into themes using template analysis.

RESULTS

Participant experienced grief at the loss of the home. Moving out and searching for a new home was highly stressful on participants and on their relationships. After being evicted, people became homeless, often staying with family and friends and lived in poor quality or unaffordable housing. They reported health issues as a result of these circumstances.

CONCLUSIONS

Eviction harms health through causing stress, grief and a move to a risky living situation. Increasing the supply of housing and funding wide-ranging support services can help minimise the harm caused by eviction. SO WHAT?: Reducing the incidence and impact of eviction should be a priority for health promotion.

Health Selection Into Eviction: Adverse Birth Outcomes and Children's Risk of Eviction Through Age 5 Years

Adverse birth outcomes put children at increased risk of poor future health. They also put families under sudden socioeconomic and psychological strain, which has poorly understood consequences. We tested whether infants experiencing an adverse birth outcome-low birthweight or prematurity, as well as lengthy hospital stays-were more likely to be evicted in early childhood, through age 5 years. We analyzed 5,655 observations contributed by 2,115 participants in the Fragile Families and Child Wellbeing Study-a national, randomly sampled cohort of infants born in large US cities between 1998 and 2000-living in rental housing at baseline. We fitted proportional hazards models using piecewise logistic regression, controlling for an array of confounders and applying inverse probability of selection weights. Having been born low birthweight or preterm was associated with a 1.74-fold increase in children's hazard of eviction (95% confidence interval: 1.02, 2.95), and lengthy neonatal hospital stays were independently associated with a relative hazard of 2.50 (95% confidence interval: 1.15, 5.44) compared with uncomplicated births. Given recent findings that unstable housing during pregnancy is associated with adverse birth outcomes, our results suggest eviction and health may be cyclical and co-constitutive. Children experiencing adverse birth outcomes are vulnerable to eviction and require additional supports.

Housing Instability and HIV Risk: Expanding our Understanding of the Impact of Eviction and Other Landlord-Related Forced Moves

The study purpose is to comprehensively measure landlord-related forced moves (inclusive of, but not restricted to, legal eviction), and to examine whether landlord-related forced moves is associated with HIV risk. Baseline survey data was collected between 2017 and 2018 among 360 low-income participants in New Haven, Connecticut. We used multivariable logistic regression analyses to examine associations between landlord-related forced moves and HIV sexual risk outcomes. Seventy seven out of three hundred and sixty participants reported a landlord-related forced move in the past 2 years, of whom 19% reported formal eviction, 56% reported informal eviction and 25% reported both. Landlord-related forced moves were associated with higher odds of unprotected sex (AOR 1.98), concurrent sex (AOR 1.94), selling sex for money or drugs (AOR 3.28), exchange of sex for a place to live (AOR 3.29), and an HIV sexual risk composite (ARR 1.46) (p < .05 for all). We found robust associations between landlord-related forced moves and HIV sexual risk. Findings suggest that the social and economic consequences of landlord-related forced moves may impact sexual vulnerability.

Association of Eviction With Adverse Birth Outcomes Among Women in Georgia, 2000 to 2016

IMPORTANCE

More than 2 million families face eviction annually, a number likely to increase due to the coronavirus disease 2019 pandemic. The association of eviction with newborns' health remains to be examined.

OBJECTIVE

To determine the association of eviction actions during pregnancy with birth outcomes.

DESIGN

This case-control study compared birth outcomes of infants whose mothers were evicted during gestation with those whose mothers were evicted at other times. Participants included infants born to mothers who were evicted in Georgia from January 1, 2000, to December 31, 2016. Data were analyzed from March 1 to October 4, 2020.

EXPOSURES

Eviction actions occurring during gestation.

MAIN OUTCOMES AND MEASURES

Five metrics of neonatal health included birth weight (in grams), gestational age (in weeks), and dichotomized outcomes for low birth weight (LBW) (<2500 g), prematurity (gestational age <37.0 weeks), and infant death.

RESULTS

A total of 88 862 births to 45 122 mothers (mean [SD] age, 26.26 [5.76] years) who experienced 99 517 evictions were identified during the study period, including 10 135 births to women who had an eviction action during pregnancy and 78 727 births to mothers who had experienced an eviction action when not pregnant. Compared with mothers who experienced eviction actions at other times, eviction during pregnancy was associated with lower infant birth weight (difference, -26.88 [95% CI, -39.53 to 14.24] g) and gestational age (difference, -0.09 [95% CI, -0.16 to -0.03] weeks), increased rates of LBW (0.88 [95% CI, 0.23-1.54] percentage points) and prematurity (1.14 [95% CI, 0.21-2.06] percentage points), and a nonsignificant increase in mortality (1.85 [95% CI, -0.19 to 3.89] per 1000 births). The association of eviction with birth weight was strongest in the second and third trimesters of pregnancy, with birth weight reductions of 34.74 (95% CI, -57.51 to -11.97) and 35.80 (95% CI, -52.91 to -18.69) g, respectively.

CONCLUSIONS AND RELEVANCE

These findings suggest that eviction actions during pregnancy are associated with adverse birth outcomes, which have been shown to have lifelong and multigenerational consequences. Ensuring housing, social, and medical assistance to pregnant women at risk for eviction may improve infant health.

Unhealthy behaviours in urban Illinois communities affected by eviction: A descriptive analysis

Eviction of renter-occupied homes is an emerging public health crisis adversely impacting populations already at risk. Although housing quality and home-owner foreclosures have been linked to health outcomes, the relationship between eviction of renter-occupied homes and health has not been well established. The demographics and socioeconomic status of renters differs from homeowners, as such any relationship with health outcomes should be distinguished between the two. The aim of this study is to provide a descriptive analysis of the relationship between renter-specific eviction and unhealthy behaviours at the census tract level. Using data from the Centers for Disease Control and Prevention 500 Cities Project, the Eviction Lab and the U.S. Census Bureau, this study assesses the relationship between eviction rates and health indicators for 1,267 urban census tracts in Illinois in 2016. Binge drinking, current smoking, no leisure-time physical activity, obesity and sleeping <7 hr were used as indicators of unhealthy behaviour as categorised by the Centers for Disease Control and Prevention500 Cities Project. Unadjusted and adjusted linear regression models were used to assess and describe the relationship between each of the dependent variables and each of the independent variables. All five of the unhealthy behaviour indicators were found to be significantly associated with eviction rates and eviction filing rates after adjustment for confounding variables. This study contributes to the understudied area of research focused on how eviction rates contribute to the social determinants of health for already at-risk populations.

The health impacts of eviction: Evidence from the national longitudinal study of adolescent to adult health

Eviction represents an urgent social and economic issue in the United States, with nearly two million evictions occurring annually in the U.S. Still, the population health impacts of evictions, as well as the pathways linking eviction to health, are not well documented or understood, particularly among young adults. Using nationally-representative, longitudinal data from the National Longitudinal Study of Adolescent to Adult Health (1994-2008) (n = 9029), the present study uses a combination of analytic methods-including prospective lagged dependent variable regression models, inverse probabilities of treatment weighting, longitudinal first difference models, causal mediation techniques-to comprehensively assess whether and how evictions relate to depressive risk and self-rated health across early adulthood, paying particular attention to the stress-related pathways linking eviction and health. Results provide robust evidence of positive longitudinal associations between eviction and depressive risk, in particular. In the prospective regression models, young adults who experienced recent eviction had more depressive symptoms and worse self-rated health than those who were not evicted, net a host of background characteristics. Using treatment weighting techniques, results showed that young adults who experienced eviction had more depressive symptoms than those who were not evicted (5.921 vs. 4.998 depressive symptoms, p = 0.003). Perceived social stress mediated nearly 18 percent of the associations between eviction and the depressive symptoms (p < 0.001). In the first difference models, young people who experienced eviction between survey waves experienced greater increases in depressive symptoms over time compared to those who were not evicted, net of changes in other indicators of socioeconomic status and residential instability. Taken together, our results suggest that the recent surges in evictions in the U.S. serve as a potent threat to population health during the emerging adult period, with especially devastating consequences for low-income individuals and communities of color.

A qualitative investigation of HIV treatment dispensing models and impacts on adherence among people living with HIV who use drugs

Antiretroviral therapy (ART) dispensing is strongly associated with treatment adherence. Among illicit drug-using populations, whom experience greater structural barriers to adherence, directly administered antiretroviral therapy (DAAT) is often regarded as a stronger predictor of optimal adherence over self-administered medications. In Vancouver, Canada, people living with HIV (PLHIV) who use drugs and live in low-income housing are a critical population for treatment support. This group is typically able to access two key DAAT models, daily delivery and daily pickup, in addition to ART self-administration. This ethno-epidemiological qualitative study explores how key dispensing models impact ART adherence among PLHIV who use drugs living in low-income housing, and how this is framed by structural vulnerability. Semi-structured interviews lasting 30-45 minutes were conducted between February and May 2018 with 31 PLHIV who use drugs recruited from an ongoing prospective cohort of PLHIV who use drugs. Interviews were audio-recorded, transcribed verbatim, and analyzed using QSR International's NVivo 12 software. Interviews focused on housing, drug use, and HIV management. Models that constrained agency were found to have negative impacts on adherence and quality of life. Treatment interruptions were framed by structural vulnerabilities (e.g., housing vulnerability) that impacted ability to maintain adherence under certain dispensing models, and led participants to consider other models. Participants using DAAT models which accounted for their structural vulnerabilities (e.g., mobility issues, housing instability), credited these models for their treatment adherence, but also acknowledged factors that constrained agency, and the negative impacts this could have on both adherence, and quality of life. Being able to integrate ART into an established routine is key to supporting ART adherence. ART models that account for the structural vulnerability of PLHIV who use drugs and live in low-income housing are necessary and housing-based supports could be critical, but the impacts of such models on agency must be considered to ensure optimal adherence.

Eviction, Health Inequity, and the Spread of COVID-19: Housing Policy as a Primary Pandemic Mitigation Strategy

The COVID-19 pandemic precipitated catastrophic job loss, unprecedented unemployment rates, and severe economic hardship in renter households. As a result, housing precarity and the risk of eviction increased and worsened during the pandemic, especially among people of color and low-income populations. This paper considers the implications of this eviction crisis for health and health inequity, and the need for eviction prevention policies during the pandemic. Eviction and housing displacement are particularly threatening to individual and public health during a pandemic. Eviction is likely to increase COVID-19 infection rates because it results in overcrowded living environments, doubling up, transiency, limited access to healthcare, and a decreased ability to comply with pandemic mitigation strategies (e.g., social distancing, self-quarantine, and hygiene practices). Indeed, recent studies suggest that eviction may increase the spread of COVID-19 and that the absence or lifting of eviction moratoria may be associated with an increased rate of COVID-19 infection and death. Eviction is also a driver of health inequity as historic trends, and recent data demonstrate that people of color are more likely to face eviction and associated comorbidities. Black people have had less confidence in their ability to pay rent and are dying at 2.1 times the rate of non-Hispanic Whites. Indigenous Americans and Hispanic/Latinx people face an infection rate almost 3 times the rate of non-Hispanic whites. Disproportionate rates of both COVID-19 and eviction in communities of color compound negative health effects make eviction prevention a critical intervention to address racial health inequity. In light of the undisputed connection between eviction and health outcomes, eviction prevention, through moratoria and other supportive measures, is a key component of pandemic control strategies to mitigate COVID-19 spread and death.

Methadone maintenance therapy service components linked to improvements in HIV care cascade outcomes: A systematic review of trials and observational studies

BACKGROUND

The beneficial links between engagement in methadone maintenance therapy (MMT) and HIV treatment outcomes have been extensively described. Nevertheless, people who use drugs (PWUD) continue to experience suboptimal HIV treatment outcomes. In this systematic review, we sought to identify components of MMT service provision that are associated with improvements in HIV care outcomes across the HIV care cascade.

METHODS

We searched for peer-reviewed studies in online databases. To be eligible for inclusion in this review, studies must have involved a population or sub-population of PWUD engaged in MMT; report improved uptake of HIV testing, exposure to ART, or HIV-1 RNA plasma viral load suppression; provide details on MMT services; and be published in English between 1 January 2006 until 31 December 2018.

RESULTS

Out of the 5594 identified records, 22 studies were eligible for this systematic review. Components of MMT services associated with HIV care cascade outcomes described in the studies were classified in three categories of care models: 1) standard MMT care with adequate doses, 2) standard MMT care and alongside additional medical component(s), and 3) standard MMT care, additional medical component(s) as well as informational or instrumental social support.

CONCLUSION

The few studies identified reflect a scarcity of evidence on the role of social support to increase the benefits of MMT for PWUD who are living with HIV. Further research is needed to assess the role of medical and social service components in MMT care delivery in advancing PWUD along the HIV care cascade.

When Crises Converge: Hospital Visits Before And After Shelter Use Among Homeless New Yorkers

People who are homeless use more hospital-based care than average, yet little is known about how hospital and shelter use are interrelated. We examined the timing of emergency department (ED) visits and hospitalizations relative to entry into and exit from New York City homeless shelters, using an analysis of linked health care and shelter administrative databases. In the year before shelter entry and the year following shelter exit, 39.3 percent and 43.3 percent, respectively, of first-time adult shelter users had an ED visit or hospitalization. Hospital visits-particularly ED visits-began to increase several months before shelter entry and declined over several months after shelter exit, with spikes in ED visits and hospitalizations in the days immediately before shelter entry and following shelter exit. We recommend cross-system collaborations to better understand and address the co-occurring health and housing needs of vulnerable populations.

Structural Barriers to Women's Sustained Engagement in HIV Care in Southern California

Since the introduction of antiretroviral therapy, the number of women living with HIV (WLHIV) continues to increase. Despite the decrease in HIV diagnosis among women in California, less than half of WLHIV are retained in HIV care. Structural barriers put women at increased risk for delayed HIV diagnosis, delayed entry into HIV care, and poorer treatment outcomes. The objective of this qualitative analysis is to identify how structural barriers negatively impact women's sustained engagement in HIV care in Southern California. WLHIV accessing local HIV support services participated in a qualitative study by completing a semi-structured interview and brief survey between January and April 2015 (n = 30). Poverty, unemployment, housing instability, and needs for transportation emerged as the dominant structural barriers for women when discussing their challenges with sustained engagement in HIV care. System-level interventions that decrease these noted barriers may help improve HIV care continuum for women living in Southern California.

Residential eviction predicts initiation of or relapse into crystal methamphetamine use among people who inject drugs: a prospective cohort study

Reports of increasing methamphetamine use among vulnerable populations may be attributed in part to the adaptive use of stimulants in response to the loss of stable housing through residential eviction. We employed multivariable recurrent event extended Cox regression to examine the independent association between recent evictions and initiation of or relapse into crystal methamphetamine use among people who inject drugs in Vancouver, Canada enrolled in two prospective cohort studies. In a multivariable analysis, eviction remained independently associated with methamphetamine initiation or relapse (adjusted hazard ratio = 1.90; 95% confidence interval: 1.31-2.75). Findings demonstrate the need to secure tenancies for drug-using populations to reduce harms.

Behavioural, social and structural-level risk factors for developing AIDS among HIV-positive people who use injection drugs in a Canadian setting, 1996-2017

People who use injection drugs (PWID) experience high rates of HIV acquisition and, as a result of lower rates of optimal access and adherence to combination antiretroviral therapy (ART), experience worse HIV treatment outcomes than other key affected populations. However, the incidence and risk factors for the development of AIDS among HIV-positive PWID have not been completely described. We used data from a community-recruited prospective cohort of HIV-positive PWID in Vancouver, Canada, a setting with universal no-cost ART and a comprehensive clinical monitoring registry. We used multivariable extended Cox models to identify factors associated with time to AIDS. Between 1996 and 2017, 396 participants, including 140 (35.4%) women, were followed for a median of 39.0 months (interquartile range: 16.6-76.2), among whom 165 (41.7%) developed AIDS. In a multivariable model, homelessness (Adjusted Hazard Ratio [AHR] = 1.76 (1.18-2.61)) and injection drug use within the preceding six months (AHR = 1.74 (1.17-2.58)) were independently associated with a higher risk of developing AIDS. Despite widespread scale-up of programmes to improve ART utilization, significant risk factors for the development of AIDS remain among HIV-positive PWID in this setting.

Home and health among people living with HIV who use drugs: A qualitative study

INTRODUCTION

Housing is a critical determinant of HIV-related outcomes among people living with HIV (PLHIV) who use drugs, including on HIV treatment adherence. Research shows that sense of home may have important implications for mitigating harms associated with low-income housing environments among PLHIV who use drugs, but how this shapes treatment is poorly understood.

METHODS

Semi-structured interviews were conducted with 31 PLHIV who use drugs recruited from an ongoing prospective cohort in Vancouver, Canada. Recruitment was targeted towards individuals living in single room occupancy housing who had previously reported low treatment adherence. Interviews were co-led with a peer research assistant, and focused on housing conditions, drug use patterns, and HIV management. Interviews were transcribed, analyzed thematically, and interpreted by drawing on concepts of home and place-making.

RESULTS

The ability to exert control over housing environments contributed to participants' perceptions of home by fostering feelings of safety and allowing for creation of personalized space. Participants readily identified the importance of housing stability and quality in maintaining health (e.g. food storage, pest-free), including HIV care. However, informed by social-structural mechanisms that undermined agency, negative experiences of home adversely impacted treatment adherence.

CONCLUSIONS

Findings indicate that sense of home may enable ability to manage HIV care, and is promoted through feelings of security within, and control over, housing environments. Supports in navigating competitive housing markets are needed to address the role that home plays in HIV treatment adherence.

Eviction in early childhood and neighborhood poverty, food security, and obesity in later childhood and adolescence: Evidence from a longitudinal birth cohort

Eviction affects a substantial share of U.S. children, but its effects on child health are largely unknown. Our objectives were to examine how eviction relates to 1) children's health and sociodemographic characteristics at birth, 2) neighborhood poverty and food security at age 5, and 3) obesity in later childhood and adolescence. We analyzed data from the Fragile Families and Child Wellbeing Study, a longitudinal cohort of children born in 20 large U.S. cities. Children who lived in rental housing with known eviction histories and measured outcomes were included. We compared maternal and infant health and sociodemographic characteristics at the time of the child's birth. We then characterized the associations between eviction and neighborhood poverty and food security at age 5 and obesity at ages 5, 9, and 15 using log binomial regression with inverse probability of treatment and censoring weights. Of the 2556 children included in objective 1, 164 (6%) experienced eviction before age 5. Children who experienced eviction had lower household income and maternal education and were more likely to be born to mothers who were unmarried, smoked during pregnancy, and had mental health problems. Evicted and non-evicted children were equally likely to experience high neighborhood poverty at age 5 (prevalence ratio (PR) = 1.03, 95% CI 0.82, 1.29) but had an increased prevalence of low food security (PR = 2.16, 95% CI 1.46, 3.19). Obesity prevalence did not differ at age 5 (PR = 1.01; 95% CI 0.58, 1.75), 9 (PR = 1.08; 95% CI 0.715, 1.55); or 15 (PR = 1.05; 95% CI 0.51, 2.18). In conclusion, children who went on to experience eviction showed signs of poor health and socioeconomic disadvantage already at birth. Eviction in early childhood was not associated with children's likelihood of neighborhood poverty, suggesting that eviction may not qualitatively change children's neighborhood conditions in this disadvantaged sample. Though we saw evidence supporting an association with low child food security at age 5, we did not find eviction to be associated with obesity in later childhood and adolescence.

•

Children who experience eviction have health and socioeconomic disadvantages at birth.

•

Eviction was not associated with neighborhood poverty or childhood obesity.

•

Evicted children (vs. not) had over twice the prevalence of food insecurity at age 5.

•

Interventions to prevent eviction can protect children from hunger and adversity.

Recent Incarceration as a Primary Barrier to Virologic Suppression Among Women Living with HIV: Results from a Longitudinal Community-Based Cohort in a Canadian Setting

Women living with HIV (WLWH) are disproportionately represented among incarcerated populations yet there is a paucity of research on how incarceration shapes HIV treatment outcomes for women. Data is drawn from SHAWNA (Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment), a longitudinal community-based open research cohort with cis and trans WLWH in Metro Vancouver, Canada (2010-2017). Multivariable logistic regression using generalized estimating equations (GEE) longitudinally modeled the effect of incarceration on virologic suppression (HIV plasma VL < 50 copies/mL), adjusting for potential confounders. Amongst 292 WLWH, the majority (74%) had been incarcerated in their lifetime and 17% were incarcerated over the study period. Exposure to recent incarceration was independently correlated with reduced odds of virologic suppression (AOR: 0.42, 95% CI 0.22-0.80). This study suggests critical need for research and interventions to better address factors shaping ART adherence and retention in care for WLWH, both within correctional centres and following release from prison.

Comparison of Two Distinct House Ball Communities Involved in an HIV Prevention Study: Baseline Data from the POSSE Project

For many Black/African American gay, bisexual, and other young men who have sex with men (B-GBMSM), the House/Ball Community (HBC) offers a social network where they can be free to express diverse sexual and gender identities, but HIV prevalence and stigma are high. The POSSE project is an effectiveness-implementation trial of a popular opinion leader intervention designed to address HIV prevention in the Chicago and Philadelphia HBCs. In June 2016 baseline behavioral data were collected along with HIV, gonorrhea and Chlamydia testing. Eligible participants were sexually-active YMSM or transgender women (TGW), between the ages of 15-24, who self-identified as Black. One-third participants (32.5%) met or exceeded the clinical cut-off for depressive symptoms. Approximately 18% of the participants across both cities reported that they were HIV-positive. Overall, the baseline data establishes the need for HIV and STI prevention interventions across both cities, as well as interventions to address other co-occurring epidemics.

Housing First: Unsuppressed Viral Load Among Women Living with HIV in San Francisco

While poverty is an established barrier to achieving success at each step of the HIV care continuum, less is known about specific aspects of poverty and how they overlap with behavior in exceptionally low-income individuals who live in well-resourced areas. We considered unsuppressed viral load over 3 years among women living with HIV in San Francisco who used homeless shelters, low-income hotels and free meal programs. One-hundred twenty study participants were followed; 60% had > 1 unsuppressed viral load and 19% were unsuppressed at every visit. Across six-month intervals, the odds of unsuppressed viral load were 11% higher for every 10 nights spent sleeping on the street [Adjusted Odds Ratio (AOR) 1.11, 95% CI 1.02-1.20]; 16% higher for every 10 nights spent sleeping in a shelter (AOR/10 nights 1.16, 95% CI 1.06-1.27); 4% higher for every 10 nights spent sleeping in a single-room occupancy hotel (AOR/10 nights 1.04, 95% CI 1.02-1.07); and over threefold higher among women who experienced any recent incarceration (AOR 3.56, 95% CI 1.84-6.86). Violence and recent use of outpatient health care did not significantly predict viral suppression in adjusted analysis. While strategies to promote retention in care are important for vulnerable persons living with HIV, they are insufficient to ensure sustained viral suppression in low-income women experiencing homelessness and incarceration. Results presented here in combination with prior research linking incarceration to homelessness among women indicate that tailored interventions, which not only consider but prioritize affordable housing, are critical to achieving sustained viral suppression in low-income women living with HIV.

Increased burden of suicidality among young street-involved sex workers who use drugs in Vancouver, Canada

BACKGROUND

The risks of suicidality among street-involved youth who use drugs and engage in sex work are not well described. This study sought to evaluate if street-involved youth who engage in sex work were at an elevated risk for attempting suicide.

METHODS

Data were derived from the At-Risk Youth Study, a prospective cohort of street-involved youth who use drugs in Vancouver, Canada. Multivariable generalized estimating equation analyses were employed to examine whether youth who engaged in sex work were at elevated risk of attempting suicide, controlling for possible confounders.

RESULTS

Between September 2005 and May 2015, 1210 youth were recruited into the cohort, of whom, 173 (14.3%) reported recently attempting suicide at some point during the study period. In multivariable analysis, youth who engaged in sex work were significantly more likely to report a recent suicide attempt (adjusted odds ratio = 1.93; 95% confidence interval: 1.28-2.91).

CONCLUSIONS

Street-involved youth who engage in sex work were observed to be at a significantly higher risk for suicidality. Systematic discrimination and unaddressed trauma may contribute to the observed increased burden of suicidality among this population. Interventions that support the mental health and well-being of street-involved youth who engage in sex work are urgently needed.

Eviction From Renter-occupied Households and Rates of Sexually Transmitted Infections: A County-level Ecological Analysis

BACKGROUND

Housing instability is linked to numerous health outcomes, but the specific impact of eviction from renter-occupied households, an event that has immediate implications for residential stability for low-income individuals, on sexually transmitted infections (STI) rates has not been adequately studied.

METHODS

We examined county-level associations between eviction rates in 2014 and rates of chlamydia and gonorrhea in the following year using publicly available data sources (Eviction Lab National Database and AtlasPlus, respectively). Descriptive statistics compared medians and nonparametric distributions with Krusal-Wallis tests. Linear regression was used to compare tertile categories of eviction rates and STI rates while controlling for potential confounders.

RESULTS

Median rates of chlamydia in counties with low, medium, and high rates of eviction were 229, 270, and 358 cases per 100,000 population, respectively (P < 0.001). The corresponding median rates of gonorrhea were 25, 37, and 75 cases per 100,000 population (P < 0.001). These associations remained statistically significant after controlling for all covariates in adjusted models. The beta coefficients and 95% confidence intervals (95% CI) for chlamydia and gonorrhea comparing high to low county-level eviction rates were 63.8 (95% CI, 45.1-82.5) and 20.4 (95% CI, 13.5-27.4), respectively. Similar associations were observed across levels of poverty and in both metropolitan and nonmetropolitan counties.

CONCLUSIONS

County-level eviction rates are associated with chlamydia and gonorrhea rates in a significant and robust way independent of other known predictors of STI. These results suggest that evictions result in residential instability in a way that may increase STI risk.

Substance Use and Adherence to Antiretroviral Therapy: What Is Known and What Is Unknown

PURPOSE OF REVIEW

People who use drugs face multiple challenges to achieve optimal HIV treatment outcomes. This review discusses the current knowledge in substance use and antiretroviral therapy adherence, highlighting recent findings and potential interventions.

RECENT FINDINGS

Studies continue to demonstrate the negative impacts of substance use and related disorders on antiretroviral therapy adherence, with the exception of cannabis. Evidence-based addiction treatment, in particular, opioid agonist therapy, appears to improve adherence levels. Most individual-level adherence specific interventions did not provide sustained effects, and no studies evaluating structural-level interventions were found. Findings suggest the urgent need to scale-up opioid agonist therapy, as well as to simultaneously address multiple structural barriers to care to optimize HIV treatment outcomes among people who use drugs.

Social and structural factors associated with greater time with a plasma HIV-1 RNA viral load above log10(1500) copies/ml among illicit drug users

OBJECTIVES

Although previous cross-sectional studies have identified correlates of detectable plasma HIV-1 RNA viral load (VL) among HIV-positive people who use drugs (PWUD), longitudinal factors associated with heightened HIV transmission potential have not been well described. Therefore, we longitudinally examined factors associated with amount of person-time spent above log10(1500) copies/ml plasma among HIV-positive PWUD in Vancouver, Canada.

DESIGN

Data were derived from a long-running prospective cohort of HIV-positive PWUD linked to comprehensive clinical records including systematic VL monitoring.

METHODS

We used generalized estimating equations modeling to longitudinally examine factors associated with person-time (in days) with a VL more than log10(1500) copies/ml plasma in the previous 180 days.

RESULTS

Between December 2005 and May 2014, 845 PWUD were eligible and included in the study. Participants spent an average of 26.8% of observation time with a VL more than log10(1500) copies/ml. In multivariable analyses, homelessness (Adjusted Rate Ratio [ARR] = 1.45) and lack of social support (ARR = 1.27) were positively associated with person-time with a VL more than log10(1500) copies/ml. Older age (ARR = 0.97) and enrolment in addiction treatment (ARR = 0.75) were negatively associated with the outcome in multivariable analyses (all P < 0.05).

CONCLUSION

Social and structural factors, including periods of homelessness or lacking in social support, were independently associated with greater amount of time with heightened HIV transmission potential. These findings suggest the need for targeted efforts to address modifiable contextual factors that contribute to increased risk of onward HIV transmission among PWUD.

Residential eviction and exposure to violence among people who inject drugs in Vancouver, Canada

BACKGROUND

People who inject drugs (PWID) experience markedly elevated rates of physical and sexual violence, as well as housing instability. While previous studies have demonstrated an association between homelessness and increased exposure to violence among PWID, the relationship between residential eviction and violence is unknown. We therefore sought to examine the association between residential eviction and experiencing violence among PWID in Vancouver, Canada.

METHODS

Data were derived from two open prospective cohort studies of PWID: the Vancouver Injection Drug Users Study (VIDUS) and the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS). We used generalized estimating equations (GEE) to estimate the relationship between residential eviction and experiencing violence among male and female PWID, respectively.

RESULTS

Between June 2007 and May 2014, 1689 participants were eligible for the analysis, contributing a median of 5.5 years of follow-up. Of these, 567 (33.6%) were female. In total, 259 (45.7%) of females and 566 (50.4%) of males experienced at least one incident of violence over the study period. In multivariable GEE models, residential eviction was independently associated with greater odds of experiencing violence among both females (Adjusted Odds Ratio [AOR]=2.09; 95% confidence interval [CI]: 1.39-3.13) and males (AOR=1.95; 95% CI=1.49-2.55), after adjustment for potential confounders.

CONCLUSION

Residential eviction was independently associated with an increased likelihood of experiencing violence among both male and female PWID. These findings point to the need for evidence-based social-structural interventions to mitigate housing instability and violence among PWID in this setting.

The association between residential eviction and syringe sharing among a prospective cohort of street-involved youth

BACKGROUND

Syringe sharing is a high-risk practice associated with the transmission of infectious diseases, such as HIV and HCV. While youth who contend with housing instability are known to be more likely to engage in high-risk substance use, the potential relationship between being evicted from housing and syringe sharing has not been examined. This study assessed whether residential eviction was associated with syringe sharing among street-involved youth in Vancouver, Canada.

METHODS

Data were derived from the At-Risk Youth Study (ARYS), a prospective cohort of street-involved youth who use drugs age 14-26 in Vancouver, Canada. The study period was June 2007 to May 2014, and the potential relationship between residential eviction and syringe sharing was analyzed using multivariable generalized estimating equations (GEE) logistic regression.

RESULTS

Among 405 street-involved youth who injected drugs, 149 (36.8%) reported syringe sharing, defined as borrowing or lending a syringe, at some point during the study period. In a multivariable GEE analysis, recent residential eviction remained independently associated with syringe sharing (adjusted odds ratio (AOR) = 1.72, 95% confidence interval (CI): 1.16-2.57), after adjusting for potential confounders.

CONCLUSIONS

Syringe sharing was significantly elevated among youth who had recently been evicted from housing. These findings indicate that policy and programmatic interventions that increase housing stability may help mitigate high-risk substance use practices among vulnerable youth.
