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

Patterns of Socioeconomic Marginalization among People Who Use Drugs: A Gender-Stratified Repeated Measures Latent Class Analysis

Socioeconomic factors are important correlates of drug use behaviors and health-related outcomes in people who use drugs (PWUD) residing in urban areas. However, less is known about the complex overlapping nature of socioeconomic conditions and their association with a range of individual, drug use, and health-related factors in men and women who use drugs. Data were obtained from two community-recruited prospective cohorts of PWUD. Using a gender-stratified approach, we conducted repeated measures latent class analyses (RMLCA) to identify discrete latent socioeconomic subgroups. Multivariable generalized estimating equations were then used to identify correlates of class membership. Between June 2014 and December 2018, RMLCA of 9844 observations from 1654 participants revealed five distinct patterns of socioeconomic status for both men and women. These patterns were primarily distinguished by variations in income, material and housing security, income generation activity, exposure to violence, criminal justice involvement, and police contact. Across gender, progressive increases in exposure to multiple dimensions of socioeconomic disadvantage were found to be associated with frequent use of opioids and stimulants, accessing social services, and being hepatitis C virus antibody-positive. Similar but less congruent trends across gender were observed for age, binge drug use, engagement with opioid agonist therapy, and living with HIV. Gendered patterns of multiple and overlapping dimensions of socioeconomic adversity aligned with patterns of frequent drug use and health-related concerns, highlighting priority areas for gender-inclusive, multilevel responses to mitigate health disparities and meet the diverse socioeconomic needs of urban-dwelling men and women who use drugs.

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.

Characteristics of Overdose Deaths Related to Illicitly Manufactured Fentanyl - Arizona, July 2019 - June 2020

Using the Arizona State Unintentional Drug Overdose Reporting System (AZ-SUDORS), the study aims to identify the social and drug characteristics of illicitly manufactured fentanyl (IMF)-related overdose deaths. The data include drug overdose deaths from July 1, 2019 to June 30, 2020. Decedents were categorized into four groups by types of opioids detected: (1) IMF-positive; (2) heroin-positive (negative for IMF); (3) pharmaceutical opioid-positive (negative for heroin or IMF); (4) nonopioid. Bivariate statistics were used to compare differences between IMF and other groups. Among 2,029 decedents, 77.8% tested positive for opioids. The IMF group included 57.9%, the heroin group included 9.5%, the pharmaceutical opioid group 10.5%, and the nonopioid group 22.2%. The IMF group was younger (mean age 35.0), more likely to be from a large urban area (78.2%), and with a greater proportion of ethnic/racial minorities (48.6%), compared to the other three groups. The IMF group was less likely to test positive for methamphetamine (24.9%), compared to heroin (63.7%) or pharmaceutical opioid groups (34.0%), but more likely to test positive for cannabis (31.3%), compared to the other three groups. Our data show disproportionate IMF impacts on younger persons and ethnic minorities. Interventions need to be tailored to account for distinct psychosocial profiles associated with IMF use.

Housing Instability Associated with Return to Stimulant Use among Previously Abstaining Women

Stimulant use among unstably housed individuals is associated with increased risks of psychiatric co-morbidity, violence, HIV transmission, and overdose. Due to a lack of highly effective treatments, evidence-based policies targeting the prevention of stimulant use disorder are of critical importance. However, little empirical evidence exists on risks associated with initiating or returning to stimulant use among at-risk populations. In a longitudinal cohort of unstably housed women in San Francisco (2016-2019), self-reported data on stimulant use, housing status, and mental health were collected monthly for up to 6 months, and factors associated with initiating stimulants after a period of non-use were identified through logistic regression. Among 245 participants, 42 (17.1%) started using cocaine and 46 (18.8%) started using methamphetamine. In analyses adjusting for demographics and socio-structural exposures over the preceding month, experiencing street homelessness was associated with initiating cocaine use (AOR: 2.10; 95% CI: 1.04, 4.25) and sheltered homelessness with initiating methamphetamine use (AOR: 2.57; 95% CI: 1.37, 4.79). Other factors-including race, income, unmet subsistence needs, mental health, and treatment adherence-did not reach levels of significance, suggesting the paramount importance of policies directed toward improving access to permanent supportive housing to prevent stimulant use among unstably housed women.

Eviction, post-traumatic stress, and emergency department use among low-income individuals in New Haven, CT

We sought to examine whether and how landlord-related forced moves (inclusive of, but not limited to, legal eviction) were associated with emergency department (ED) use over time. We used survey data collected between 2017 and 2019 among 283 low-income participants in New Haven, CT to examine whether experiencing a legal eviction or other landlord-related forced move (T₀) was associated with increased odds of ED use 6 months (T₁) and 12 months (T₂) later. We conducted bootstrapped mediation analyses to examine indirect effects of post-traumatic stress symptoms. One-fifth of participants (n = 61) reported a recent forced move at baseline (T₀); half of these were legally evicted. Landlord-related forced moves were associated with ED use at T₁ (AOR = 2.06, 95 % CI: 1.04-4.06) and T₂ (AOR = 3.05, 95 % CI: 1.59-5.88). After adjustment for sociodemographic factors and other health-related confounders, legal eviction was not significantly associated with ED use at T₁ (AOR = 1.61, 95 % CI: 0.68-3.81), but was significantly associated with ED use at T₂ (AOR = 3.58, 95 % CI: 1.58-8.10). Post-traumatic stress symptoms accounted for 15.1% of forced moves' association with ED use (p <.05). Landlord-related forced moves are positively associated with subsequent ED use, and post-traumatic stress symptoms are one factor that may help explain this association. Structural interventions that promote housing stability are needed to advance health equity, and they may also help to reduce preventable ED use. Such interventions are imperative in the context of the COVID-19 pandemic, which has strained health system capacity and exacerbated housing instability for many low-income renters. Results underscore the relevance of trauma-informed care and integrated care management to clinical practice in emergency settings.

Acute care utilization and housing hardships in American children

Millions of families in the United States are economically vulnerable: one shock can lead to hardship. We use data from the Fragile Families and Child Wellbeing Study to examine the association between acute healthcare utilization - emergency room visits or hospitalizations - and subsequent housing hardships, such as being evicted for financial reasons. Further, we explore whether this association differs by who in the family utilized the care and whether perceived social support protects against hardship when these experiences occur. Using lagged dependent variable regression models, we find that families that visited the emergency room or were hospitalized, regardless if it was a child or parent with this experience, were five percentage points more likely to experience any housing hardship than families that did not use acute care. Among families in which a child utilized acute care, perceived social support buffered the impact of using acute care. That perceived social support is associated with a lower likelihood of housing hardship among families that experienced acute care utilization for a child, but not parent, suggests that social support may be able to offset the challenges arising from children's, but not adults', use of acute care. In the face of economic precarity, informal safety nets may be insufficient to reduce the impact of acute care utilization on housing hardships.

Racial/Ethnic and Geographic Trends in Combined Stimulant/Opioid Overdoses, 2007-2019

In the United States, combined stimulant/opioid overdose mortality has risen dramatically over the last decade. These increases may particularly affect non-Hispanic Black and Hispanic populations. We used death certificate data from the US National Center for Health Statistics (2007-2019) to compare state-level trends in overdose mortality due to opioids in combination with 1) cocaine and 2) methamphetamine and other stimulants (MOS) across racial/ethnic groups (non-Hispanic White, non-Hispanic Black, Hispanic, and non-Hispanic Asian American/Pacific Islander). To avoid unstable estimates from small samples, we employed principles of small area estimation and a Bayesian hierarchical model, enabling information-sharing across groups. Black Americans experienced severe and worsening mortality due to opioids in combination with both cocaine and MOS, particularly in eastern states. Cocaine/opioid mortality increased 575% among Black people versus 184% in White people (Black, 0.60 to 4.05 per 100,000; White, 0.49 to 1.39 per 100,000). MOS/opioid mortality rose 16,200% in Black people versus 3,200% in White people (Black, 0.01 to 1.63 per 100,000; White, 0.09 to 2.97 per 100,000). Cocaine/opioid overdose mortality rose sharply among Hispanic and Asian Americans. State-group heterogeneity highlighted the importance of data disaggregation and methods to address small sample sizes. Research to understand the drivers of these trends and expanded efforts to address them are needed, particularly in minoritized groups.

Crystal methamphetamine use subgroups and associated addiction care access and overdose risk in a Canadian urban setting

OBJECTIVES

Methamphetamine use is rising globally and we have limited treatments for this. Subgroups within the diverse methamphetamine-using population may have distinct treatment needs. Among a community-recruited sample of people who use crystal methamphetamine, we aimed to identify subgroups and characterize their overdose risk and access to addiction care.

METHODS

Data from prospective cohorts of people who use drugs in Vancouver, Canada from 2014 to 2018 were used to conduct a repeated measures latent class analysis among participants who used crystal methamphetamine. Multivariable generalized estimating equations models were fit to determine the associated factors.

RESULTS

Among 824 eligible participants, a five-class model was identified as the best fit: (1) primary stimulant use (15.7%); (2) women engaged in sex work and opioid use (21.4%); (3) street income generation and opioid use (31.6%); (4) opioid agonist therapy (OAT) patients (22.3%); and (5) men who have sex with men (9.0%). In multivariable analyses, compared to the primary stimulant use group, non-fatal overdose was positively associated with street income generation (adjusted odds ratio [AOR] = 1.49, 95% confidence interval [95% CI]=1.30-1.71), sex work (AOR = 1.38, 95% CI=1.20-1.59) and OAT (AOR = 1.22, 95% CI=1.06-1.41) subgroups; engagement in non-OAT addiction care was negatively associated with street income generation (AOR = 0.81, 95% CI=0.68-0.97) and sex work (AOR = 0.78, 95% CI=0.63-0.98) subgroups.

DISCUSSION

Socioeconomically marginalized subgroups with opioid and crystal methamphetamine co-use were at highest risk of non-fatal overdose and had poorer access to addiction care, highlighting the need for tailored interventions.

Frequency of reported methamphetamine use linked to prevalence of clinical conditions, sexual risk behaviors, and social adversity in diverse men who have sex with men in Los Angeles

OBJECTIVE

This study tested the hypothesis that reported frequency of methamphetamine use is significantly associated with measures of social adversity, sexual risk behaviors, chronic health conditions, bacterial STIs and HIV-related factors among diverse men who have sex with men (MSM).

METHODS

Data were 2428 visits from 515 mSTUDY participants (261 people living with HIV; 254 HIV-negative). mSTUDY is an ongoing longitudinal study of racially/ethnically diverse MSM in Los Angeles County. Logistic regression with random intercepts modeled associations between self-reported past 6-month methamphetamine use (none, monthly or less, weekly or more) with reported adverse social outcomes (unemployment, housing instability, intimate partner violence), sexual risk behaviors, chronic health conditions, and biomarkers of bacterial STIs (chlamydia, gonorrhea, or syphilis) and detectable HIV viral load (among HIV-positive). Models controlled for confirmed HIV-serostatus.

RESULTS

Prevalence of reported monthly or less methamphetamine use was 19%; weekly or more use was 18%. Multivariable models showed escalating odds of adverse social outcomes and sexual risk behaviors (p's < 0.001) with increased methamphetamine use frequency. Frequency of methamphetamine use associated with increased odds of a positive bacterial STI test (p < .001), detectable viral load (in HIV-positive participants) (p < .001), renal condition (p = .047), neurological condition (p = .008), and psychological condition (p = .001).

CONCLUSIONS

Findings show cross-sectional links between reported methamphetamine use frequency and adverse social and health outcomes among MSM in Los Angeles and suggest there may be fewer social and physical health harms corresponding to less frequent use of methamphetamine in this group.

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.

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.

Crystal methamphetamine use in British Columbia, Canada: A cross-sectional study of people who access harm reduction services

INTRODUCTION

Increased use of crystal methamphetamine ("crystal meth") has been observed across North America and international jurisdictions, including a notable increase in the presence of methamphetamines in illicit drug toxicity deaths in British Columbia (BC), Canada. We used data from a cross-sectional survey and urine toxicology screening to report the prevalence, correlates, and validity of self-reported crystal meth use among clients of harm reduction sites in BC.

MATERIALS AND METHODS

Survey data were collected from 1,107 participants across 25 communities in BC, through the 2018 and 2019 Harm Reduction Client Survey. We described reported substance use and used a multivariate logistic regression model to characterize crystal meth use. Urine samples provided by a subset of participants were used to derive validity of self-reported three-day crystal meth use compared to urine toxicology screening.

RESULTS

Excluding tobacco, crystal meth was the most frequently reported substance used in the past three days in 2018 and 2019 (59.7% and 71.7%, respectively). Smoking was the dominant route of administration for crystal meth, crack, heroin, and fentanyl. Multivariate analysis determined significantly higher odds of crystal meth use among those who used opioids (Adjusted Odds Ratio [AOR] = 3.13), cannabis (AOR = 2.10), and alcohol (1.41), and among those who were not regularly housed (AOR = 2.08) and unemployed (AOR = 1.75). Age ≥50 was inversely associated with crystal meth use (AOR = 0.63). Sensitivity of self-reported crystal meth use was 86%, specificity was 86%, positive predictive value was 96%, and negative predictive value was 65%.

CONCLUSIONS

Crystal meth was the most commonly used substance among clients of harm reduction sites in BC in 2018 and 2019, and was frequently used concurrently with opioids. Comparison to urine samples demonstrated high validity of self-reported crystal meth use. Understanding evolving patterns of substance use will be imperative in tailoring harm reduction and substance use services for individuals that use crystal meth.

Navigating post-eviction drug use amidst a changing drug supply: A spatially-oriented qualitative study of overlapping housing and overdose crises in Vancouver, Canada

BACKGROUND

North American cities are experiencing intersecting housing and overdose crises as illicit drug markets become marked by the proliferation of fentanyl and methamphetamine. Despite recent research documenting associations between evictions and drug-related risks and harms, including overdose, the mechanisms through which these occur remain poorly understood. This study to examines how evictions shape the drug use practices of people who use drugs in Vancouver's Downtown Eastside - a neighbourhood with an established drug scene - as the illicit drug supply changed.

METHODS

Qualitative interviews and geo-spatial data collection were conducted with 56 recently evicted PWUD. Data were analyzed by interfacing qualitative and geo-spatial data, and interpreted focusing on how structural vulnerability shaped spatial practices and drug-related risks post-eviction.

RESULTS

Findings demonstrate how post-eviction spatial practices and routines produced risk and harm as participants navigated the uncertainties of housing vulnerability and drug supply changes. Post-eviction disruptions complicated participants' ability to engage with trusted drug sellers. Changes to spatial patterns and access to private spaces rendered public drug use inevitable, though this was mitigated to some degree by harm reduction supports. Abrupt changes to drug use patterns occurred due to post-eviction disruptions and included instrumental uses of methamphetamine to increase alertness and navigate survival amidst severe hardship.

CONCLUSIONS

Findings demonstrate how post-eviction changes to routines and spatial patterns are framed by structural vulnerability and can exacerbate drug-related harms, particularly in the context of a changing drug supply. There is an urgent need for structural interventions and harm reduction responses to mitigate harms associated with evictions.

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.

Eviction as a Disruptive Factor in Health Care Utilization: Impact on Hospital Readmissions and No-show Rates

BACKGROUND

Residential eviction is a component of housing instability that negatively affects physical and mental health, but the effect of eviction on health care utilization, specifically hospital readmissions and outpatient no-show rates, is not known.

METHODS

We conducted a retrospective review of health care utilization of individuals evicted from public housing between January 2013 and December 2017, investigating hospital readmissions and no-show rates one year before and after eviction.

RESULTS

131 individuals who had been evicted had one year of data pre-and post-eviction. The majority were African American (97.7%) and female (80.9%). There was no significant change in 30-, 60-, and 90-day hospital readmissions (p>.05). No-show rate decreased from 27.57 per person per year to 20.13 (p=.05).

CONCLUSIONS

For our study population, health care utilization was not disrupted. The decreased no-show rate represents an opportunity for health systems to engage with patients on social factors affecting their health post-eviction.

In utero exposure to threat of evictions and preterm birth: Evidence from the United States

OBJECTIVE

To estimate county-level associations between in utero exposure to threatened evictions and preterm birth in the United States.

DATA SOURCES

Complete birth records were obtained from the National Center for Health Statistics (2009-2016). Threatened evictions were measured at the county level using eviction case filing data obtained from The Eviction Lab (2008-2016). Additional economic and demographic data were obtained from the United States Census Bureau and Bureau of Labor Statistics.

STUDY DESIGN

We conducted a retrospective cohort analysis using 7.3 million births from 1,633 counties. We defined threatened eviction exposures as the z-score of average case filings over the pregnancy and by trimester. Our primary outcome was an indicator for preterm birth (born < 37 completed weeks of gestation). Secondary outcomes included a continuous measure for gestational length, a continuous measure for birth weight, and an indicator for low birth weight (born < 2500 g). We estimated within-county associations controlling for individual- and time-varying county-level characteristics, state-of-residence-year-and-month-of-conception fixed effects, and a county-specific time trend.

DATA COLLECTION/EXTRACTION

We merged birth records with threatened eviction data at the county-month-year level using mother's county of residence at delivery and month-year of conception. We supplemented these data with information on county-level annual 18-and-over population, annual poverty rate, and monthly unemployment rate.

PRINCIPAL FINDINGS

Increased levels of eviction case filings over a pregnancy were associated with an increased risk of prematurity and low birth weight. These associations appeared to be sensitive to exposure in the second and third trimesters. Associations with secondary outcomes and within various population subgroups were, in general, imprecisely estimated.

CONCLUSIONS

Higher exposure to eviction case filings within counties, particularly in the latter stages of a pregnancy, was associated with an increased risk of adverse birth outcomes. Future research should identify the causal effect of threatened evictions on maternal and child health outcomes.

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.

The effect of evictions on accidental drug and alcohol mortality

OBJECTIVE

To assess the relationship between county-level eviction rates and drug and alcohol mortality rates.

DATA SOURCES

Eviction rates from 2003 to 2016 provided by the Princeton University Eviction Lab were merged with Multiple Cause-of-Death Mortality Files and aggregated to the county-year level.

STUDY DESIGN

All opioid (prescription and heroin), cocaine, psychostimulant, benzodiazepine, antidepressant, and alcohol poisoning-related deaths per 100 000 people, eviction rates, and socioeconomic indicators were merged at the county-year level from 2003 to 2016. We estimated a series of mortality rate models with county and year fixed effects and used a control function (2SRI) method to adjust for the endogeneity of eviction rates.

DATA COLLECTION/EXTRACTION METHODS

We matched retrospectively collected datasets.

PRINCIPAL FINDINGS

Higher levels of eviction rates were consistently associated with higher rates of mortality across six of nine substance categories studied when all counties were combined. Subanalysis by USDA population density measures indicated this positive association was almost entirely driven by urban counties; few systematic associations between the eviction rate levels and mortality were observed for suburban or rural counties.

CONCLUSIONS

Risk of eviction appears to exacerbate the current "deaths of despair" crisis associated with substance use. Proposed changes to Housing and Urban Development policy that are expected to substantially increase the risk of eviction may worsen an already-acute mortality crisis.

Methamphetamine Use and Its Correlates among Individuals with Opioid Use Disorder in a Midwestern U.S. City

Background: U.S. is experiencing a surging trend of methamphetamine use among individuals who use opioids. More research is needed to characterize this emerging "twin epidemic." Objectives: The study aims to identify social and behavioral characteristics associated with methamphetamine use among individuals with opioid use disorder (OUD) in the Dayton, Ohio, area, an epicenter of the opioid crisis and an emerging frontier of methamphetamine epidemic. Methods: 357 adult individuals with current OUD were recruited using targeted and respondent-driven sampling. Structured interviews collected information on social and drug use characteristics. Multivariable Logistic Regression was used to identify characteristics associated with the past 6-month use of methamphetamine. Results: 49.7% were female, and 88.8% were non-Hispanic whites. 55.6% used methamphetamine in the past 6-months, and 84.9% reported first use of methamphetamine after initiation of illicit opioids. Methamphetamine use was associated with homelessness (aOR = 2.46, p = .0001), lifetime history of diverted pharmaceutical stimulant use (aOR = 2.97, p < .001), injection route of heroin/fentanyl use (aOR = 1.89, p = .03), preference for fentanyl over heroin (aOR = 1.82, p = .048), lifetime history of extended-release injectable naltrexone (Vivitrol)-based treatment (aOR = 2.89, p = .003), and more frequent marijuana use (aOR = 1.26, p = .04). Discussion: The findings point to the complexity of motivational and behavioral pathways associated with methamphetamine and opioid co-use, ranging from self-treatment and substitution behaviors, attempts to endure homelessness, and greater risk taking to experience euphoria. More research is needed to understand the causal relationships and the association between methamphetamine and Vivitrol use. Public health responses to the opioid crisis need to be urgently expanded to address the growing epidemic of methamphetamine use.

Prevalence and correlates of HIV infection among people who use drugs in Cambodia: a cross-sectional survey using respondent driven sampling method

Background

Most of studies on the relationship between drug use and HIV have focused largely on people who inject drugs. Non-injecting drug use is much more common than injecting drug use, and although it can also predispose people to HIV infection, it is not widely explored. We therefore conducted this study to explore the prevalence of HIV and identify risk factors for HIV infection among people who use non-injecting drugs (PWUD) in Cambodia.

Methods

This cross-sectional study was conducted in 2017. The Respondent Driven Sampling method was used to recruit the study participants who were interviewed face-to-face using a structured questionnaire. Blood samples were collected for HIV and syphilis testing. A multivariable logistic regression analysis was conducted to identify risk factors associated with HIV infection.

Results

In total, 1367 PWUD were included in this study, whose mean age was 28.0 (SD = 7.7) years. The majority (95.1%) of the participants used methamphetamine. The prevalence of HIV was 5.7, and 35.2% of the identified HIV-positive PWUD were not aware of their status prior to the survey. After adjustment for other covariates, HIV infection remained significantly associated with being in the age group of ≥35 (AOR = 2.34, 95% CI = 1.04–6.11), having lower level of formal education of ≤ 6 years (AOR = 2.26, 95% CI = 1.04–5.15), living on the streets (AOR = 2.82, 95% CI = 1.10–7.23), perception that their HIV risk was higher as compared to that of the general population (AOR = 3.18, 95% CI = 1.27–8.62), having used injecting drugs in lifetime (AOR = 3.8, 95% CI = 1.36–4.56), and having cuts or sores around the genital area in the past 12 months (AOR = 3.42, 95% CI = 1.09–6.33).

Conclusions

The prevalence of HIV among PWUD in this study was more than 10 times higher than the prevalence in the general adult population. The findings reveal a higher vulnerability to HIV infection among specific sub-populations of PWUD, such as those who are homeless, who may benefit from tailored interventions that respond to their specific needs. To enhance HIV case finding, stratification of PWUD to facilitate HIV risk profiling based on socio-economic profiles and drug injection history is recommended.

Homelessness and incarceration associated with relapse into stimulant and opioid use among youth who are street-involved in Vancouver, Canada

INTRODUCTION AND AIMS

While much research has sought to identify the factors associated with initiation and cessation of various forms of drug use among vulnerable youth, little is known about relapse into drug use in this population. We sought to characterise relapse into stimulant and opioid use among street-involved youth in Vancouver, Canada.

DESIGN AND METHODS

Data were collected between 2005 and 2017 from the At-Risk Youth Study, a prospective cohort study of street-involved youth who use illicit drugs in Vancouver. Multivariable extended Cox regression was utilised to identify factors associated with relapse into illegal stimulants and/or opioids among youth who had previously ceased using stimulants and/or opioids for 6 months or longer.

RESULTS

Among 246 participants who reported a period of cessation lasting 6 months or longer, 165 (67.1%) relapsed at some point during study follow-up. Youth who were recently incarcerated (adjusted hazard ratio [AHR]: 1.46), homeless (AHR: 1.43), or had a history of daily stimulant use (AHR: 1.48) were significantly more likely to report relapse, while youth of who identified as white (AHR: 0.74) were significantly less likely to report relapse (all P < 0.05).

DISCUSSION AND CONCLUSIONS

Relapse into stimulants and/or opioids was common among youth in our setting, and incarceration, homelessness, and daily stimulant use were found to be positively associated with relapse among youth. Findings suggest that increased access to youth housing supports and alternatives to the criminalisation of drug use may help to reduce the rates of relapse into stimulants and/or opioids in this population.

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.
