Friedman SR, Rossi D, Perlman DC. Historical and theoretical roots of the big events framework. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 133:104606. [PMID: 39378779 DOI: 10.1016/j.drugpo.2024.104606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 07/25/2024] [Accepted: 09/26/2024] [Indexed: 10/10/2024]
Abstract
This article traces the evolution of the Big Events framework since it began as an attempt to understand why sociopolitical transitions in the Former Soviet Union, South Africa, and Indonesia were followed by HIV outbreaks. Big Events frameworks have evolved over time, but all versions try to concretize how macrosocial changes lead to social, personal and environmental changes that shape risk environments and drug use or other behavioral patterns in ways that may lead to epidemics. Important stages in the evolution of the Big Events framework included understanding that the sequelae of Big Events were contingent rather than deterministic, and the development of new survey measures to understand pathways through which Big Events affect social and epidemiologic outcomes. On a broader level, the Big Events framework is a useful crystallization and application of more abstract sociological, social epidemiologic and Marxist frameworks about upstream/downstream relationships and how major social changes are related to epidemics. As such, they raise issues of how to conduct research on dialectical interaction processes. On another level, this article traces the Big Events "style of thought" as Mannheim (Mannheim, 1971) termed it, within the historical context of changes in public health and social science theory, particularly during and after the 1960s.

Public Health 2024; 231:80-87.

Abstract
OBJECTIVES This paper aims to examine the psychometric properties of social capital indicators, comparing Black and White respondents to identify the extent of measurement invariance in social capital by race. STUDY DESIGN We used data from the longitudinal study Midlife in the United States (MIDUS), waves 1 through 3 (1995-2016). METHODS Data were from 6513 respondents (5604 White and 909 Black respondents). Social capital indicators were social cohesion, contributions to community, and community involvement. We used Structural Equation Modeling and Item Response Theory methods to test for measurement invariance in social capital by race. RESULTS We observed violations of longitudinal and multi-group measurement invariance (MI) at configural and metric levels on two scales. Factor structures and indicator loadings were inconsistent over time. In IRT analysis, 'Many people come for advice' exhibited Differential Item Functioning (DIF), indicating a consistent advantage for White respondents on the contributions to community scale. Despite similar social capital levels (P(χ2,2) = 0.00), DIF was found in all contributions to community items and some community involvement items when examining race and education interaction. CONCLUSIONS Invariance issues in social capital items suggest potential biases in comparing Black and White respondents. Recognizing these biases is essential. Future social capital research should assess existing data assumptions and involve stakeholders from diverse communities in creating new items.

Abstract
Recognizing challenges faced by people living with HIV is vital for improving their HIV treatment outcomes. While individual-level interventions play a crucial role, community factors can shape the impact of individual interventions on treatment outcomes. Understanding neighborhood characteristics' association with HIV treatment outcomes is crucial for optimizing effectiveness. This review aims to summarize the research scope on the association between neighborhood characteristics and HIV treatment outcomes. The databases PubMed, CINAHL (EBSCOhost), Embase (Elsevier), and PsychINFO (EBSCOhost) were searched from the start of each database to Nov 21, 2022. Screening was performed by three independent reviewers. Full-text publications of all study design meeting inclusion criteria were included in the review. There were no language or geographical limitations. Conference proceedings, abstract only, and opinion reports were excluded from the review. The search yielded 7,822 publications, 35 of which met the criteria for inclusion in the review. Studies assessed the relationship between neighborhood-level disadvantage (n = 24), composition and interaction (n = 17), social-economic status (n = 18), deprivation (n = 16), disorder (n = 8), and rural-urban status (n = 7) and HIV treatment outcomes. The relationship between all neighborhood characteristics and HIV treatment outcomes was not consistent across studies. Only 7 studies found deprivation had a negative association with HIV treatment outcomes; 6 found that areas with specific racial/ethnic densities were associated with poor HIV treatment outcomes, and 5 showed that disorder was associated with poor HIV treatment outcomes. Three studies showed that rural residence was associated with improved HIV treatment outcomes. There were inconsistent findings regarding the association between neighborhood characteristics and HIV treatment outcomes. While the impact of neighborhood characteristics on disease outcomes is highly recognized, there is a paucity of standardized definitions and metrics for community characteristics to support a robust assessment of this hypothesis. Comparative studies that define and assess how specific neighborhood indicators independently or jointly affect HIV treatment outcomes are highly needed.

Institutional violence from police militarization and drug cartel wars as a 'Big Event' and its influence on drug use harms and HIV risk in people who inject drugs on the U.S.-Mexico border. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 119:104125. [PMID: 37499305 DOI: 10.1016/j.drugpo.2023.104125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 07/05/2023] [Accepted: 07/07/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Globally, the US-Mexico Border is one of the largest drug trafficking regions, with Ciudad Juarez (CJ) and El Paso (EP) making up the second-largest border crossing in the world. Border communities are places where the risk of drug use harm and infectious diseases such as HIV are augmented due to the confluence of factors operating across the physical, social, economic and policy environment. Although the two cities are economically, culturally, and socially intertwined, each has distinct criminal justice systems and policy practices aimed at curtailing substance use. Between 2008 and 2011, the CJ/EP region experienced an unprecedented level of violence that stemmed from the intersection of police militarization and drug cartel wars, which profoundly shaped every aspect of life. Little research has documented the impact of drug cartel wars on the drug use and health harms of people who inject drugs (PWID) living in CJ and EP. The purpose of the study is to understand the effect that the drug cartel war had on the drug use harms and HIV risk of PWID. METHODS We conducted 40 in-depth interviews with people who inject drugs who resided in CJ or EP and had used heroin or crack cocaine in the last 30 days, and asked how police militarization and drug cartel war affected their daily lives. The risk environment framework informed the analysis and interpretation of findings. RESULTS Findings indicated that the risk environment was profoundly altered as PWID residing in CJ experienced profound changes in their daily lives that promoted engagement in behaviors that increased drug use and health harms including HIV risk, exacerbated trauma, and prevented use of substance use treatment and harm reduction services. The risk environment was also altered in EP, where PWID experienced drug supply shortages, violent policing practices, and reduced availability of harm reduction services. Findings underscore the permeability of risk environments across geographical borders. CONCLUSION The intersection of law enforcement militarization and drug cartel wars can be conceptualized as a 'big event' because it disrupts the drug market economy, leads to drug shortages, promotes entrance into the drug market economy by people who use drugs, reshapes drug use sites, and constrains the provision of harm reduction services. The stability of the harm reduction system in CJ was negatively impacted and limited the ability of individuals to reduce harm. Our findings show that drug cartel wars render the CJ/EP region extremely susceptible to drug use and health harms, while also creating vulnerability by severely restricting its ability to respond. Traditional recommendations to intervene to limit the impact of risk environments on the drug use harms of PWID need to be reconsidered in the context of drug cartel wars.

Abstract
The following paper presents case examples of one research team's use of social network analysis (SNA) with three different collaboratives in South Florida: (a) a Collective Impact initiative seeking to end youth homelessness, (b) a university collaborative of campus organizations working towards Black students' concerns, and (c) a movement network of local social justice organizations. The research team used SNA to assess the level of connectivity of three different community coalitions. While research questions were slightly different for each collaborative, each project asked about the frequency of communication between organizations to determine connectivity. Results vary between case examples. Both the Youth Homeless Collaboration and the Black Student Association used Gephi to analyze results, while The Community Partnership used R to measure network centrality. The paper concludes with a general discussion of challenges related to using SNA as an action research tool, as well as the role of power in organizational networks.

Abstract
We examined whether race/ethnic-specific social cohesion is associated with race/ethnic-specific HIV diagnosis rates using Bayesian space-time zero-inflated Poisson multivariable models, across 376 Census tracts. Social cohesion data were from the Southeastern Pennsylvania Household Health Survey, 2008-2015 and late HIV diagnosis data from eHARS system, 2009-2016. Areas where trust in neighbors reported by Black/African Americans was medium (compared to low) had lower rates of late HIV diagnosis among Black/African Americans (Relative Risk (RR)=0.52, 95% credible interval (CrI)= 0.34, 0.80). In contrast, areas where trust in neighbors reported by Black/African Americans were highest had lower late HIV diagnosis rates among Whites (RR=0.35, 95% CrI= 0.16, 0.76). Race/ethnic-specific differences in social cohesion may have implications for designing interventions aimed at modifying area-level social factors to reduce racial disparities in late HIV diagnosis.

Abstract
This review aims to delineate the role of structural racism in the formation and accumulation of social capital and to describe how social capital is leveraged and used differently between Black and White people as a response to the conditions created by structural racism. We draw on critical race theory in public health praxis and restorative justice concepts to reimagine a race-conscious social capital agenda. We document how American capitalism has injured Black people and Black communities' unique construction of forms of social capital to combat systemic oppression. The article proposes an agenda that includes communal restoration that recognizes forms of social capital appreciated and deployed by Black people in the United States that can advance health equity and eliminate health disparities. Developing a race-conscious social capital framing that is inclusive of and guided by Black community members and academics is critical to the implementation of solutions that achieve racial and health equity and socioeconomic mobility.

Abstract
BACKGROUND Big events (i.e., unique historical disruptions) like the COVID-19 epidemic and its associated period of social distancing can transform social structures, social interactions, and social norms. Social distancing rules and the fear of infection have greatly reduced face-to-face interactions, increased loneliness, reduced ties to helping institutions, and may also have disrupted the opioid use behaviors of people who use drugs. This research used Reddit to examine the impact of COVID-19 on the social networks and social processes of people who use opioids. METHODS Data were collected from the social media forum, Reddit.com. At the beginning of the COVID-19 pandemic in the U.S. (March 5, 2020, to May 13, 2020), 2,000 Reddit posts were collected from the two most popular opioid subreddits (r/OpiatesRecovery, r/Opiates). Posts were reviewed for relevance to COVID-19 and opioid use resulting in a final sample of 300. Thematic analysis was guided by the Big Events framework. RESULTS The COVID-19 pandemic was found to create changes in the social networks and daily lives among persons who use opioids. Adaptions to these changes shifted social networks leading to robust social support and mutual aid on Reddit, including sharing and seeking advice on facing withdrawal, dealing with isolation, managing cravings, and accessing recovery resources. CONCLUSIONS Reddit provided an important source of social support and mutual aid for persons who use opioids. Findings indicate online social support networks are beneficial to persons who use opioids, particularly during big events where isolation from other social support resources may occur.

Abstract
More than 750,000 people in the United States died from an overdose between 1999 and 2018; two-thirds of those deaths involved an opioid. In this review, we present trends in opioid overdose rates during this period and discuss how the proliferation of opioid prescribing to treat chronic pain, changes in the heroin and illegally manufactured opioid synthetics markets, and social factors, including deindustrialization and concentrated poverty, contributed to the rise of the overdose epidemic. We also examine how current policies implemented to address the overdose epidemic may have contributed to reducing prescription opioid overdoses but increased overdoses involving illegal opioids. Finally, we identify new directions for research to understand the causes and solutions to this critical public health problem, including research on heterogeneous policy effects across social groups, effective approaches to reduce overdoses of illegal opioids, and the role of social contexts in shaping policy implementation and impact.

Abstract
The opioid/overdose crisis in the United States and Canada has claimed hundreds of thousands of lives and has become a major field for research and interventions. It has embroiled pharmaceutical companies in lawsuits and possible bankruptcy filings. Effective interventions and policies toward this and future drug-related outbreaks may be improved by understanding the sociostructural roots of this outbreak. Much of the literature on roots of the opioid/overdose outbreak focuses on (1) the actions of pharmaceutical companies in inappropriately promoting the use of prescription opioids; (2) "deaths of despair" based on the deindustrialization of much of rural and urban Canada and the United States, and on the related marginalization and demoralization of those facing lifetimes of joblessness or precarious employment in poorly paid, often dangerous work; and (3) increase in occupationally-induced pain and injuries in the population. All three of these roots of the crisis-pharmaceutical misconduct and unethical marketing practices, despair based on deindustrialization and increased occupational pain-can be traced back, in part, to what has been called the "one-sided class war" that became prominent in the 1970s, became institutionalized as neo-liberalism in and since the 1980s, and may now be beginning to be challenged. We describe this one-sided class war, and how processes it sparked enabled pharmaceutical corporations in their misconduct, nurtured individualistic ideologies that fed into despair and drug use, weakened institutions that created social support in communities, and reduced barriers against injuries and other occupational pain at workplaces by reducing unionization, weakening surviving unions, and weakening the enforcement of rules about workplace safety and health. We then briefly discuss the implications of this analysis for programs and policies to mitigate or reverse the opioid/overdose outbreak.

Abstract
BACKGROUND Sharing drug injection equipment has been associated with the transmission of HCV among PWID through blood contained in the cooker and cotton used to prepare and divide up the drug solution. While epidemiologists often subsume this practice under the sharing of "ancillary equipment," more attention should be paid to the fact that indirect sharing takes place within the process of joint drug acquisition and preparation. METHODS We employed an ethnographic approach observing active PWID (N = 33) in four rural towns in Puerto Rico in order to document drug sharing arrangements involved in "caballo", as this practice is locally known. We explored partners' motivation to engage in drug sharing, as well as its social organization, social roles and existing norms. FINDINGS Findings suggest that drug sharing, is one of the main drivers of the HCV epidemic in this population. Lack of financial resources, drug packaging, drug of choice and the desire to avoid the painful effects of heroin withdrawal motivates participants' decision to partner with somebody else, sharing injection equipment-and risk-in the process. Roles are not fixed, changing not only according to caballo partners, but also, power dynamics. CONCLUSION In order to curb the HCV epidemic, harm reduction policies should recognize the particular sociocultural contexts in which people inject drugs and make decisions about risk. Avoiding sharing of injection equipment within an arrangement between PWID to acquire and use drugs is more complex than assumed by harm reduction interventions. Moving beyond individual risk behaviors, a risk environment approach suggest that poverty, and a strict drug policy that encourage users to carry small amounts of illicit substances, and a lack of HCV treatment among other factors, contribute to HCV transmission.

Abstract
Objectives: Discrimination, such as being treated unfairly due to race, contributes to stress. Individuals may cope with this by engaging in risky behaviors. Consistent with this premise, prior studies found that discrimination is associated with substance use. Research has also shown that sex while 'high' on alcohol and drugs is associated with increased risk for HIV and other STIs. The present study examines the relationship between discrimination and sexual risk. We investigate whether discrimination is associated with sex while high on alcohol and drugs. Design: Analyses focus on a sample of 356 Caribbean Diasporic young adults, primarily Caribbean Latinx, aged 18 to 25 who participated in the Drug Use and HIV Risk among Youth Survey carried out from 1997 to 2000 in Brooklyn, New York. Logistic regression examined the association between self-reported discrimination and sex while high. Results: More than half (52.3%) of respondents reported moderate discrimination. Sex while high was also reported: 35.7% for alcohol, 43.3% for marijuana, and 32.6% for heroin/cocaine. Discrimination was associated with increased risk of sex while high on (1) marijuana and (2) heroin/cocaine, but was not with alcohol. Conclusions: Discrimination may be a risk factor for engaging in sex while high on drugs, which may put individuals at risk for HIV as well as other STIs. Future research should explore relationships between discrimination and sex while high on alcohol and drugs among various racial/ethnic groups and Diasporas, while also assessing how this relationship may contribute to HIV incidence.

Abstract
Social capital is associated with the health of people living with HIV, and yet few studies have examined social capital in relation to the HIV continuum of care in the United States. The current study assessed individual social capital within social networks of 251 people living with HIV and residing in a rural area of the southeastern United States. Participants completed computerized self-administered measures that included markers of social capital and disclosure of HIV status to network members. We estimated individual social capital for each relationship identified in the social network interviews and tested regression models at three points along the HIV continuum of care: receiving ART, ART adherence, and HIV viral suppression. Results indicated that one in four participants had not disclosed their HIV status to at least one member of their social network and disclosure was not associated with social capital. Regression models showed that participants with larger social networks and less social capital were more likely to be receiving ART and more likely to have HIV suppressed viral loads. Alcohol use, not social capital, was related to ART non-adherence. Participant's depressive symptomatology was unrelated to any HIV care continuum metrics assessed in this study. We conclude that social capital is drawn upon at critical points along the HIV continuum of care. Interventions should focus on building social capital within social networks and provide support to key network members when patients are transitioning into care, initiating ART and experiencing HIV unsuppressed viral loads.

Abstract
Efforts to reduce HIV among gay, bisexual and other men who have sex with men include increasing awareness and uptake of pre-exposure prophylaxis (PrEP). Social capital may facilitate engagement in HIV prevention. Membership of social groups including chosen families (i.e. friends as family relationships) - one potential indicator of social capital - may be protective against HIV risk and infection. In this cross-sectional quantitative study, we examined social capital items and social group membership in association with PrEP outcomes. In 2014, the New Orleans arm of the National HIV Behavioral Surveillance recruited 353 HIV-negative men, of whom 46% identified as Black, Latino or Other Race and 54% as Non-Hispanic White, using venue-based sampling to complete a structured survey. Multivariable logistic regression models tested the relations between social group membership and social capital with PrEP indicators. Men who reported community group participation were more likely to be aware of PrEP compared to those who did not. Men in chosen families associated with a family name were least likely to be aware of and willing to take PrEP compared to those not in any other social groups. Social group membership is a potential social capital indicator for assessing HIV prevention among men.

Abstract
Background Young adults who experience homelessness are exposed to environments that contribute to risk behavior. However, few studies have examined how access to housing may affect the health risk behaviors of young adults experiencing homelessness. Objective This paper describes the Log My Life study that uses an innovative, mixed-methods approach based on geographically explicit ecological momentary assessment (EMA) through cell phone technology to understand the risk environment of young adults who have either enrolled in housing programs or are currently homeless. Methods For the quantitative arm, study participants age 18-27 respond to momentary surveys via a smartphone app that collects geospatial information repeatedly during a 1-week period. Both EMAs (up to 8 per day) and daily diaries are prompted to explore within-day and daily variations in emotional affect, context, and health risk behavior, while also capturing infrequent risk behaviors such as sex in exchange for goods or services. For the qualitative arm, a purposive subsample of participants who indicated engaging in risky behaviors are asked to complete an in-depth qualitative interview using an interactive, personalized geospatial map rendering of EMA responses. Results Recruitment began in June of 2017. To date, 170 participants enrolled in the study. Compliance with EMA and daily diary surveys was generally high. In-depth qualitative follow-ups have been conducted with 15 participants. We expect to recruit 50 additional participants and complete analyses by September of 2019. Conclusions Mixing the quantitative and qualitative arms in this study will provide a more complete understanding of differences in risk environments between homeless and housed young adults. Furthermore, this approach can improve recall bias and enhance ecological validity. International Registered Report Identifier (IRRID) DERR1-10.2196/12112

Abstract
Despite previous empirical studies which have linked social capital to a number of health outcomes, few studies have investigated sub-group specific social capital among populations at increased risk for HIV infection such as gay, bisexual and other men who have sex with men (GBM). Many GBM of color belong to constructed families in which friends refer to each other with kinship terms such as parents and children. No studies have measured social capital provisions within constructed family networks. This study developed a preliminary instrument for assessing social capital among constructed families. The network level social capital scale incorporated the following theoretical domains hypothesized to define social capital derived from network membership: social influence, multiplex ties, heterogeneity, social cohesion, trust, quality of support, and compositional quality. A cross-sectional survey administered an eight-item scale to 131 GBM who belonged to constructed families. The factor structure and confirmatory factor analysis were assessed. Reliability was evaluated using Cronbach's alpha to measure internal consistency. A final single factor solution was obtained which was comprised of six items with high factor loadings. The resulting measures were highly correlated with an alpha of 0.84 and each factor loading was well above 0.3. This study assessed the psychometric properties of a preliminary network level social capital instrument among GBM in constructed families. Future studies may utilize or adopt this scale to measure network-level social capital within other populations.

Abstract
Purpose Social capital is a well-established predictor of several behavioral health outcomes. However, we know less about the relationship with prevention, transmission, and treatment of HIV/AIDS outcomes in the United States (US). Methods In 2017, we conducted a scoping review of empirical studies investigating the relationships between social capital and HIV/AIDS in the US by searching PubMed, Embase, PsycINFO, Web of Science, and Sociological Abstracts with no restriction on publication date, for articles in English language. Sample search terms included: HIV infections OR HIV OR AIDS OR acquired immunodeficiency syndrome OR human immunodeficiency virus AND social capital OR social control, informal OR social participation OR social cohesion OR generalized trust OR social trust OR collective efficacy OR community mob* OR civic participation. Results We identified 1581 unique manuscripts and reviewed 13 based on eligibility criteria. The earliest eligible study was published in 2003. More than half (n=7/13) focused on HIV or AIDS diagnosis, then prescribing ART and/or adherence (n=5/13), then linkage and or engagement in HIV care (n=4/13). Fifty eight percent (58%) documented a protective association between at least one social capital measure and an HIV/AIDS outcome. Seven studies used validated social capital scales, however there was substantial variation in conceptual/operational definitions and measures used. Most studies were based on samples from the Northeast. Three studies directly focused on or stratified analyses among subgroups or key populations. Studies were cross-sectional, so causal inference is unknown. Conclusion Our review suggests that social capital may be an important determinant of HIV/AIDS prevention, transmission, and treatment outcomes. We recommend future research assess these associations using qualitative and mixed-methods approaches, longitudinally, examine differences across subgroups and geographic region, include a wider range of social capital constructs, and examine indicators beyond HIV diagnosis, as well as how mechanisms like stigma link social capital to HIV/AIDS.

Abstract
A life history approach enables study of how risk or health protection is shaped by critical transitions and turning points in a life trajectory and in the context of social environment and time. We employed visual and narrative life history methods with people who inject drugs to explore how hepatitis C protection was enabled and maintained over the life course. We overview our methodological approach, with a focus on the ethics in practice of using life history timelines and life-grids with 37 participants. The life-grid evoked mixed emotions for participants: pleasure in receiving a personalized visual history and pain elicited by its contents. A minority managed this pain with additional heroin use. The methodological benefits of using life history methods and visual aids have been extensively reported. Crucial to consider are the ethical implications of this process, particularly for people who lack socially ascribed markers of a "successful life."

Abstract
Our objective was to understand factors that support or undermine sexual and reproductive health care use among women released from jail. We conducted semistructured interviews with 28 women (ages 20-53) on average 6 months after their release from a city jail. Social support networks were the most common factor that supported women's sexual and reproductive health care use; having a medical home, reliable transportation, financial resources, and neighborhood dynamics were other factors mentioned by health care users. Community-based public health efforts should address the social context in which women on the margins of society perceive sexual health risk and use sexual and reproductive health care services.

Abstract
BACKGROUND People who inject drugs (PWID) take on significant risks of contracting blood-borne infection, including injecting with a large number of partners and acquiring needles from unsafe sources. When combined, risk of infection can be magnified. METHODS Using a sample of PWID in rural Puerto Rico, we model the relationship between a subject's number of injection partners and the likelihood of having used an unsafe source of injection syringes. Data collection with 315 current injectors identified six sources of needles. RESULTS Of the six possible sources, only acquisition from a seller (paid or free), or using syringes found on the street, was significantly related to number of partners. CONCLUSIONS These results suggest that sources of syringes do serve to multiply risk of infection caused by multi-partner injection concurrency. They also suggest that prior research on distinct forms of social capital among PWID may need to be rethought.

Abstract
Background Twitter represents a social media platform through which medical cannabis dispensaries can rapidly promote and advertise a multitude of retail products. Yet, to date, no studies have systematically evaluated Twitter behavior among dispensaries and how these behaviors influence the formation of social networks. Objectives This study sought to characterize common cyberbehaviors and shared follower networks among dispensaries operating in two large cannabis markets in California. Methods From a targeted sample of 119 dispensaries in the San Francisco Bay Area and Greater Los Angeles, we collected metadata from the dispensary accounts using the Twitter API. For each city, we characterized the network structure of dispensaries based upon shared followers, then empirically derived communities with the Louvain modularity algorithm. Principal components factor analysis was employed to reduce 12 Twitter measures into a more parsimonious set of cyberbehavioral dimensions. Finally, quadratic discriminant analysis was implemented to verify the ability of the extracted dimensions to classify dispensaries into their derived communities. Results The modularity algorithm yielded three communities in each city with distinct network structures. The principal components factor analysis reduced the 12 cyberbehaviors into five dimensions that encompassed account age, posting frequency, referencing, hyperlinks, and user engagement among the dispensary accounts. In the quadratic discriminant analysis, the dimensions correctly classified 75% (46/61) of the communities in the San Francisco Bay Area and 71% (41/58) in Greater Los Angeles. Conclusions The most centralized and strongly connected dispensaries in both cities had newer accounts, higher daily activity, more frequent user engagement, and increased usage of embedded media, keywords, and hyperlinks. Measures derived from both network structure and cyberbehavioral dimensions can serve as key contextual indicators for the online surveillance of cannabis dispensaries and consumer markets over time.

Abstract
Understanding the short- and long-term transmission dynamics of blood-borne illnesses in network contexts represents an important public health priority for people who inject drugs and the general population that surrounds them. The purpose of this article is to compare the risk networks of urban and rural people who inject drugs in Puerto Rico. In the current study, network characteristics are drawn from the sampling "trees" used to recruit participants to the study. We found that injection frequency is the only factor significantly related to clustering behavior among both urban and rural people who inject drugs.

Abstract
Social network analysis (SNA) and social network-based interventions (SNI) are important analytical tools harnessing peer and family influences critical for HIV prevention and treatment among substance users. While SNA is an effective way to measure social network influences, SNI directly or indirectly involves network members in interventions. Even though these methods have been applied in heterogeneous ways, leading to extensive evidence-based practices, systematic reviews are however, lacking. We searched five bibliographic databases and identified 58 studies involving HIV in substance users that had utilized SNA or SNI as part of their methodology. SNA was used to measure network variables as inputs in statistical/mathematical models in 64 % of studies and only 22 % of studies used SNI. Most studies focused on HIV prevention and few addressed diagnosis (k = 4), care linkage and retention (k = 5), ART adherence (k = 2), and viral suppression (k = 1). This systematic review highlights both the advantages and disadvantages of social network approaches for HIV prevention and treatment and gaps in its use for HIV care continuum.

Network dynamics of HIV risk and prevention in a population-based cohort of young Black men who have sex with men. ACTA ACUST UNITED AC 2017.

Abstract
AbstractCritical to the development of improved HIV elimination efforts is a greater understanding of how social networks and their dynamics are related to HIV risk and prevention. In this paper, we examine network stability of confidant and sexual networks among young black men who have sex with men (YBMSM). We use data from uConnect (2013–2016), a population-based, longitudinal cohort study. We use an innovative approach to measure both sexual and confidant network stability at three time points, and examine the relationship between each type of stability and HIV risk and prevention behaviors. This approach is consistent with a co-evolutionary perspective in which behavior is not only affected by static properties of an individual's network, but may also be associated with changes in the topology of his or her egocentric network. Our results indicate that although confidant and sexual network stability are moderately correlated, their dynamics are distinct with different predictors and differing associations with behavior. Both types of stability are associated with lower rates of risk behaviors, and both are reduced among those who have spent time in jail. Public health awareness and engagement with both types of networks may provide new opportunities for HIV prevention interventions.

Abstract
The altruism and/or solidarity of people who inject drugs helps protect sex and drug partners from HIV. Research has been hindered by lack of measures. We developed and administered scales to assess them to 300 people who inject drugs. Altruism and Solidarity Scales were both internally consistent. Each correlated significantly with measures of helping others. These measures appear reliable and valid. They can be used to study how big events or structural interventions affect altruism and solidarity, and how altruism and solidarity are associated with changes in HIV or other risks, among people who inject drugs.

The role of neighborhoods in shaping perceived norms: An exploration of neighborhood disorder and norms among injection drug users in Baltimore, MD. Health Place 2015; 33:181-6.

Abstract
A large literature suggests that social norms contribute to HIV and substance use related behaviors. Less attention has been given to neighborhood factors that may contribute to the development of norms about risky behaviors. We examined the cross-sectional associations between perceptions of one's neighborhood and norms of perceived prevalence of, and peer support for sex exchange and risky injection behaviors. The sample consisted of 719 people who reported injecting heroin and cocaine and did not move in the past 6 months in Baltimore, MD. Living in a neighborhood with disorder was associated with believing that others exchanged sex, practiced risky injection behaviors (descriptive norms) and approved of risky injection behavior (injunctive norms).

Abstract
BACKGROUND This paper examines how family and social relations facilitate and inhibit adherence to antiretroviraltherapy (ART) for people living with HIV (PLH) who have underlying substance use disorders and are transitioningto the community post-incarceration. METHODS Combining the methods of inductive close reading and constantcomparison, we analyzed the data from 30 semi-structured interviews of PLH who had recently transitioned to thecommunity within the previous 90 days. RESULTS Three central themes were anticipated as important socialrelationships post-release: self-reported family, friends and clinicians. Among these, four sub-themes (social isolation, 'double jeopardy', search for belonging, and trust and respect) emerged, highlighting how they impacted ART adherence. Post-release, participants returned to resource-poor communities where they experienced socialisolation. ART adherence was enabled by having a purpose in life, which correlated with having robust family support structures. Many former prisoners felt that a chasm between them and their families existed, both because of HIV stigma and their addiction problems. In this context, relationships with untrustworthy friends from their druguse networks led to relapse of drug use and risky behaviors, jeopardizing participants' ART adherence and persistence. To avoid the double jeopardy, defined as seeking friends for support but who were also the ones who contributed to drug relapse, participants searched for new social anchors, which often included their healthcare providers who represented trusted and respected persons in their life. CONCLUSIONS While some former prisonersperceived doctors as uncaring and their relationships asymmetrical, positive relationships with these providers,when respect and trust was mutual, reinforced the participants' sense of belonging to what they called 'the world that don't do drugs' and motivated them to adhere to ART.

Abstract
We describe a general framework for modeling and stochastic simulation of epidemics in realistic dynamic social networks, which incorporates heterogeneity in the types of individuals, types of interconnecting risk-bearing relationships, and types of pathogens transmitted across them. Dynamism is supported through arrival and departure processes, continuous restructuring of risk relationships, and changes to pathogen infectiousness, as mandated by natural history; dynamism is regulated through constraints on the local agency of individual nodes and their risk behaviors, while simulation trajectories are validated using system-wide metrics. To illustrate its utility, we present a case study that applies the proposed framework towards a simulation of HIV in artificial networks of intravenous drug users (IDUs) modeled using data collected in the Social Factors for HIV Risk survey.

A pilot cohort study to assess the feasibility of HIV prevention science research among men who have sex with men in Dakar, Senegal. J Int AIDS Soc 2013; 16 Suppl 3:18753.

Abstract
INTRODUCTION Men who have sex with men (MSM) are disproportionately burdened by HIV in Senegal, across sub-Saharan Africa and throughout the world. This is driven in part by stigma, and limits health achievements and social capital among these populations. To date, there is a limited understanding of the feasibility of prospective HIV prevention studies among MSM in Senegal, including HIV incidence and cohort retention rates. METHODS One hundred and nineteen men who reported having anal sex with another man in the past 12 months were randomly selected from a sampling frame of 450 unique members of community groups serving MSM in Dakar. These men were enrolled in a 15-month pilot cohort study implemented by a community-based partner. The study included a structured survey instrument and biological testing for HIV, syphilis and hepatitis B virus at two time points. RESULTS Baseline HIV prevalence was 36.0% (43/114), with cumulative HIV prevalence at study end being 47.2% (51/108). The annualized incidence rate was 16% (8/40 at risk for seroconversion over 15 months of follow-up, 95% confidence interval 4.6-27.4%). Thirty-seven men were lost to follow up, including at least four deaths. Men who were able to confide in someone about health, emotional distress and sex were less likely to be HIV positive (OR 0.36, p < 0.05, 95% CI 0.13, 0.97). CONCLUSIONS High HIV prevalence and incidence, as well as mortality in this young population of Senegalese MSM indicate a public health emergency. Moreover, given the high burden of HIV and rate of incident HIV infections, this population appears to be appropriate for the evaluation of novel HIV prevention, treatment and care approaches. Using a study implemented by community-based organizations, there appears to be feasibility in implementing interventions addressing the multiple levels of HIV risk among MSM in this setting. However, low retention across arms of this pilot intervention, and in the cohort, will need to be addressed for larger-scale efficacy trials to be feasible.

Abstract
Patterns of risk in injecting drug user (IDU) networks have been a key focus of network approaches to HIV transmission histories. New network modeling techniques allow for a reexamination of these patterns with greater statistical accuracy and the comparative weighting of model elements. This paper describes the results of a reexamination of network data from the SFHR and P90 data sets using Exponential Random Graph Modeling. The results show that "transitive closure" is an important feature of IDU network topologies, and provides relative importance measures for race/ethnicity, age, gender, and number of risk partners in predicting risk relationships.

Safe havens and rough waters: networks, place, and the navigation of risk among injection drug-using Malaysian fishermen. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2013; 25:575-82.

Abstract
BACKGROUND HIV prevalence among Malaysian fishermen is ten times that of the general population. Fishing boats are a key place where drug use occurs, but we know little about how these environments shape HIV risk behaviour. Utilizing Rhodes' 'risk environment' framework, we assessed drug use contexts and how characteristics of place associated with fishing and fishermen's social networks served as key axes along which drug use and HIV risk behaviour occurred. METHODS Data were collected during 2009-2011 in Kuantan, a fishing port on the eastern coast of Malaysia, and include 28 in-depth interviews and 398 surveys collected using RDS. Logistic regression was used to determine the effect of occupational, network and risk environment characteristics on unsafe injection behaviour and access to clean needles/syringes; qualitative data were coded and analyzed thematically. RESULTS Drug injecting was common and occurred on boats, often with other crewmembers. Captains and crewmembers were aware of drug use. Unsafe injection practices were significantly associated with having a larger proportion of drug injectors in network (OR=3.510, 95% CI=1.053-11.700) and having a captain provide drugs for work (OR=2.777, 95% CI=1.018-7.576). Size of fishermen network (OR=0.987, 95% CI=0.977-0.996), crewmembers' knowledge of drug use (OR=7.234, 95% CI=1.430-36.604), and having a captain provide drugs for work (OR=0.134, 95% CI=0.025-0.720) predicted access to clean needles/syringes. Qualitative analyses revealed that occupational culture and social relationships on boats drove drug use and HIV risk. CONCLUSIONS While marginalized in broader society, the acceptance of drug use within the fishing community created occupational networks of risk. Fishing boats were spaces of both risk and safety; where drug users participated in the formal economy, but also where HIV risk behaviour occurred. Understanding the interplay between social networks and place is essential for developing HIV prevention and harm reduction policies appropriate for the unique needs of this fishing population.

Abstract
Economic and political instability and related "big events" are widespread throughout the globe. Although they sometimes lead to epidemic HIV outbreaks, sometimes they do not-and we do not understand why. Current behavioural theories do not adequately address these processes, and thus cannot provide optimal guidance for effective intervention. Based in part on a critique of our prior "pathways" model of big events, we suggest that cultural-historical activity theory (CHAT) may provide a useful framework for HIV research in this area. Using CHAT concepts, we also suggest a number of areas in which new measures should be developed to make such research possible.

Abstract
Associations between social support network characteristics and sexual risk among racially/ethnically diverse young men who have sex with men (YMSM) were examined using egocentric network data from a prospective cohort study of YMSM (n = 501) recruited in New York City. Bivariate and multivariable logistic regression analyses examined associations between social support network characteristics and sexual risk taking behaviors in Black, Hispanic/Latino, and White YMSM. Bivariate analyses indicated key differences in network size, composition, communication frequency and average relationship duration by race/ethnicity. In multivariable analyses, controlling for individual level sociodemographic, psychosocial and relationship factors, having a sexual partner in one's social support network was associated with unprotected sexual behavior for both Hispanic/Latino (AOR = 3.90) and White YMSM (AOR = 4.93). Further examination of key network characteristics across racial/ethnic groups are warranted in order to better understand the extant mechanisms for provision of HIV prevention programming to racially/ethnically diverse YMSM at risk for HIV.

Abstract
Neighborhood factors have been linked to HIV risk behaviors, HIV counseling and testing, and HIV medical care. However, the social-psychological mechanisms that connect neighborhood factors to HIV-related behaviors have not been fully determined. In this article we review the research on neighborhood factors and HIV-related behaviors, approaches to measuring neighborhoods, and mechanisms that may help to explain how the physical and social environment within neighborhoods may lead to HIV-related behaviors. We then discuss organizational, geographic, and social network approaches to intervening in neighborhoods to reduce HIV transmission and facilitate HIV medical care with the goal of reducing morbidity and mortality and increasing social and psychological well-being.

Abstract
In 2001, Friedman et al. conjectured the existence of a "firewall effect" in which individuals who are infected with HIV, but remain in a state of low infectiousness, serve to prevent the virus from spreading. To evaluate this historical conjecture, we develop a new graph-theoretic measure that quantifies the extent to which Friedman's firewall hypothesis(FH)holds in a risk network. We compute this new measure across simulated trajectories of a stochastic discrete dynamical system that models a social network of 25,000 individuals engaging in risk acts over a period of 15 years. The model's parameters are based on analyses of data collected in prior studies of the real-world risk networks of people who inject drugs (PWID) in New York City. Analysis of system trajectories reveals the structural mechanisms by which individuals with mature HIV infections tend to partition the network into homogeneous clusters (with respect to infection status) and how uninfected clusters remain relatively stable (with respect to infection status) over long stretches of time. We confirm the spontaneous emergence of network firewalls in the system and reveal their structural role in the nonspreading of HIV.

Abstract
OBJECTIVES We evaluated network mixing and influences by network members upon Black men who have sex with men. METHODS We conducted separate social and sexual network mixing analyses to determine the degree of mixing on risk behaviors (e.g., unprotected anal intercourse [UAI]). We used logistic regression to assess the association between a network "enabler" (would not disapprove of the respondent's behavior) and respondent behavior. RESULTS Across the sample (n = 1187) network mixing on risk behaviors was more assortative (like with like) in the sexual network (r(sex), 0.37-0.54) than in the social network (r(social), 0.21-0.24). Minimal assortativity (heterogeneous mixing) among HIV-infected men on UAI was evident. Black men who have sex with men reporting a social network enabler were more likely to practice UAI (adjusted odds ratio = 4.06; 95% confidence interval = 1.64, 10.05) a finding not observed in the sexual network (adjusted odds ratio = 1.31; 95% confidence interval = 0.44, 3.91). CONCLUSIONS Different mixing on risk behavior was evident with more disassortativity among social than sexual networks. Enabling effects of social network members may affect risky behavior. Attention to of high-risk populations' social networks is needed for effective and sustained HIV prevention.

Abstract
Drug markets in disadvantaged African American neighborhoods have altered social and sexual norms as well as sexual networks, which impact an individual's risk of contracting a sexually transmitted infection. Presently, we describe the prevalence of sexual partnerships with males involved with illegal drugs among a sample of non-drug-dependent females. In 2010, 120 Black females aged 18 to 30 years completed a semistructured HIV-risk interview. Descriptive statistics revealed approximately 80% of females perceived neighborhood drug activity as a major problem, 58% had sex with a male drug dealer, 48% reported sex with a male incarcerated for selling drugs, and 56% believed drug dealers have the most sexual partners. Our results suggest sexual partnerships with males involved in the distribution of drugs are prevalent. These partnerships may play a substantial role in the spread of sexually transmitted infections among low-risk females, as drug dealers likely serve as a bridge between higher HIV-risk drug and prison populations and lower HIV-risk females. However, the significance of partnerships with males involved in drug dealing has received little attention in HIV and drug abuse literature. Presently, there is a need for more research focused on understanding the extent to which the drug epidemic affects the HIV risk of non-drug-dependent Black female residents of neighborhoods inundated with drugs. Special consideration should be given to the role of the neighborhood drug dealer in the spread of sexually transmitted infections.

Perceptions of neighborhood social environment and drug dependence among incarcerated women and men: a cross-sectional analysis. SUBSTANCE ABUSE TREATMENT PREVENTION AND POLICY 2012; 7:39.

Abstract
BACKGROUND Perception of neighborhood social environment can influence an individual's susceptibility to drug dependence. However, this has never been examined with a jailed sample, where frequent transitions between local jails and disadvantaged neighborhoods are common. Understanding these associations could aid in the design of targeted programs to decrease drug dependence and recidivism among the incarcerated. METHODS For this study, 596 women and men from three Kansas City jails were surveyed over the course of six months in 2010. Drug dependence was assessed with DSM-IV criteria. Independent variables included fear of one's neighborhood, perceived level of neighborhood violence, and social capital. All data were self-reported and were analyzed using logistic regression. RESULTS Controlling for gender and age, fear of neighborhood violence was associated with increased odds of having drug dependence (OR = 1.27, CI 1.02, 1.58) and a higher level of social capital prior to incarceration was associated with lower odds of drug dependence (OR = 0.65, CI 0.44, 0.96). Mental health problem diagnosis and past year intimate partner violence were significant mediating factors. Gender and race/ethnicity were significant moderating factors between neighborhood disadvantage and drug dependence. CONCLUSIONS Our study suggests that drug dependence programs for women and men who cycle between jails and communities require both individual- and community-level interventions. To be most effective, programs at the community-level should focus on helping specific groups navigate their communities, as well as address individual health needs associated with drug dependence.

Abstract
HIV-infected current and former drug users utilize primary care and preventive health services at suboptimal rates, but little is known about how social support networks are associated with health services use. We investigated the relationship between social support networks and the use of specific types of health services by HIV-infected drug users receiving methadone maintenance. We found that persons with greater social support, in particular more social network members or more network members aware of their HIV status, were more likely to use primary care services. In contrast, social support networks were not related to emergency room or inpatient hospital use. Interventions that build social support might improve coordinated and continuous health services utilization by HIV-infected persons in outpatient drug treatment.

Abstract
AIMS AND OBJECTIVES The aim of this paper is to raise the awareness of social network analysis as a method to facilitate research in nursing research. BACKGROUND The application of social network analysis in assessing network properties has allowed greater insight to be gained in many areas including sociology, politics, business organisation and health care. However, the use of social networks in nursing has not received sufficient attention. DESIGN Review of literature and illustration of the application of the method of social network analysis using research examples. METHODS First, the value of social networks will be discussed. Then by using illustrative examples, the value of social network analysis to nursing will be demonstrated. RESULTS The method of social network analysis is found to give greater insights into social situations involving interactions between individuals and has particular application to the study of interactions between nurses and between nurses and patients and other actors. CONCLUSION Social networks are systems in which people interact. Two quantitative techniques help our understanding of these networks. The first is visualisation of the network. The second is centrality. Individuals with high centrality are key communicators in a network. RELEVANCE TO CLINICAL PRACTICE Applying social network analysis to nursing provides a simple method that helps gain an understanding of human interaction and how this might influence various health outcomes. It allows influential individuals (actors) to be identified. Their influence on the formation of social norms and communication can determine the extent to which new interventions or ways of thinking are accepted by a group. Thus, working with key individuals in a network could be critical to the success and sustainability of an intervention. Social network analysis can also help to assess the effectiveness of such interventions for the recipient and the service provider.

Abstract
Studies have shown that position within networks of social relations can have direct implications on the health behaviors of individuals. The present study examines connections between drug use and individual social capital within social networks of drug users (n = 503) from rural Appalachian Kentucky, U.S.A. Respondent driven sampling was used to recruit individuals age 18 and older who had used one of the following drugs to get high: cocaine, crack, heroin, methamphetamine, or prescription opioids. Substance use was measured via self-report and social network analysis of participants' drug use network was used to compute effective size, a measure of social capital. Drug network ties were based on sociometric data on recent (past 6 month) drug co-usage. Multivariate multi-level ordinal regression was used to model the independent effect of socio-demographic and drug use characteristics on social capital. Adjusting for gender, income, and education, daily OxyContin(®) use was found to be significantly associated with greater social capital, and daily marijuana use was associated with less social capital. These results suggest that in regions with marked economic disparities such as rural Appalachia, OxyContin(®) may serve as a form of currency that is associated with increased social capital among drug users. Interventions focusing on increasing alternate pathways to acquiring social capital may be one way in which to alleviate the burden of drug use in this high-risk population.

Abstract
Neighborhood social capital-resources inherent within community networks-has been identified as a potential facilitator of personal well-being. We test hypotheses concerning how neighborhood social capital moderates the influence of parenting strain on mastery (individuals' understanding of their ability to control personal life circumstances) for female primary caregivers of children. First, we test how different forms of neighborhood social capital-social support, social leverage (information exchange), informal social control, and neighborhood organization participation-modify the association between parenting strain and mastery. Second, we test whether such moderation depends on one's access to these forms via neighbor ties. Analyses of Los Angeles Family and Neighborhood Survey data (N = 765) indicate that the negative relationship between parenting strain and mastery worsens as informal social control increases. Social support and informal social control, however, buffer this parenting strain-mastery relationship when caregivers have stronger ties to neighbors. Our findings implicate mechanisms of "negative social capital" and warrant more nuanced considerations of neighborhood social capital's health-promoting potential.

HIV risk among MSM in Senegal: a qualitative rapid assessment of the impact of enforcing laws that criminalize same sex practices. PLoS One 2011; 6:e28760.

Abstract
Men who have sex with men (MSM) are at high risk for HIV in Senegal, with a prevalence of 21.5%. In December 2008, nine male HIV prevention workers were imprisoned for “acts against nature” prohibited by Senegalese law. This qualitative study assessed the impact of these arrests on HIV prevention efforts. A purposive sample of MSM in six regions of Senegal was recruited by network referral. 26 in-depth interviews (IDIs) and 6 focus group discussions (FGDs) were conducted in July–August 2009. 14 key informants were also interviewed. All participants reported pervasive fear and hiding among MSM as a result of the December 2008 arrests and publicity. Service providers suspended HIV prevention work with MSM out of fear for their own safety. Those who continued to provide services noticed a sharp decline in MSM participation. An effective response to the HIV epidemic in Senegal should include active work to decrease enforcement of this law.

Abstract
Social capital and health research has emerged as a focus of contemporary behavioral epidemiology, while intervention research is seeking more effective measures to increase health protective behaviors and decrease health-risk behaviors. In this review we explored current literature on social capital and health outcomes at the micro-, mesa-, and macro-levels with a particular emphasis on research that incorporates a social capital framework, and adolescent and young adult engagement in risk behaviors. These data indicate that across a broad range of socio-cultural and economic contexts, social capital can affect individuals’ risk for negative health outcomes and their engagement in risk behaviors. Further research is needed which should focus on differentiating and measuring positive and negative social capital within both mainstream and alternative social networks, assessing how social constructions of gender, ethnicity, and race – within specific cultural contexts – mediate the relationship between social capital and risk and/or protective behaviors. This new research should integrate the existing research within historical socioeconomic and political conditions. In addition, social capital scales need to be developed to be both culturally and developmentally appropriate for use with adolescents living in a diversity of settings. Despite the proliferation of social capital research, the concept remains underutilized in both assessment and intervention development for adolescents’ and young adults’ engagement in risk behaviors and their associated short- and long-term poor health outcomes.

Abstract
This article discusses relevant literature on group sex events--defined as events at which some people have sex with more than one partner--as risk environments, with a particular focus on group sex events where people who take drugs by non-injection routes of administration participate and where the event is not primarily LGBT-identified, at a "classic" crack house, nor in a brothel. It also briefly presents some findings from a small ethnography of such events. Group sex participation by people who take drugs by non-injection routes of administration seems to be widespread. It involves both behavioural and network risk for HIV and STI infection, including documented high-risk behaviour and sexual mixing of STI- and HIV-infected people with those who are uninfected. Indeed several HIV and STI outbreaks have been documented as based on such group sex events. Further, group sex events often serve as potential bridge environments that may allow infections to pass from members of one high-risk-behavioural category to another, and to branch out through these people's sexual and/or injection networks to other members of the local community. The ethnographic data presented here suggest a serious possibility of "third party transmission" of infectious agents between people who do not have sex with each other. This can occur even when condoms are consistently used since condoms and sex toys are sometimes used with different people without being removed or cleaned, and since fingers and mouths come into contact with mucosal surfaces of other members of the same or opposite sex. In addition to being risk environments, many of these group sex events are venues where risk-reducing norms, activities and roles are present--which lays the basis for harm reduction interventions. Research in more geographical locations is needed so we can better understand risks associated with group sex events in which drug users participate--and, in particular, how both participants and others can intervene effectively to reduce the risks posed to participants and non-participants by these group sex events. Such interventions are needed and should be developed.

Environmental conditions, political economy, and rates of injection drug use in large US metropolitan areas 1992-2002. Drug Alcohol Depend 2010; 106:142-53.

Abstract
City-specific studies have suggested the quality of the local environment and economic circumstances are associated with greater risk of injection drug use (IDU). No studies have assessed the relation among the quality of the local environment, economic circumstances, and IDU over time across US metropolitan areas. Annual numbers of IDUs in the 88 largest US metropolitan statistical areas (MSAs) were estimated by extrapolating, adjusting, and allocating existing estimates using various data sources. Generalized estimating equations were used to assess the relation among the quality of the local environment, metropolitan political economy, and IDU prevalence using lagged models taking into account potential confounders. MSAs with a worse local environment (measured as a one standard deviation difference) had a greater risk of IDU (relative risk [RR]=1.03, 95% confidence interval [CI]: 1.01, 1.06); similarly, a one-percentage point worsening of the political economy for an MSA was associated with greater risk of IDU (RR=1.04-1.10). Final models stratified by region indicated heterogeneity of effect by region whereby the quality of the local environment was associated with IDU strongest in the South (RR=1.12, CI: 1.05, 1.12) followed by the West (RR=1.04, CI: 1.01, 1.07) and Midwest (RR=1.03, CI: 1.00, 1.06), and the metropolitan political economy was associated with IDU in the West (RR=1.03-1.09) and Northeast (RR=1.04-1.12). Our results underscore the importance of sociopolitical factors as determinants of IDU in MSAs. Structural solutions targeted at improving environmental conditions and economic circumstances should be considered as drug use interventions.
