Introduction Forced migration is occurring at unprecedented levels. Forced migrants may be at risk for substance use for reasons including coping with traumatic experiences, co-morbid mental health disorders, acculturation challenges and social and economic inequality. This paper aimed to systematically review the literature examining substance use among forced migrants, and identify priority areas for intervention and future research. Methods Seven medical, allied health and social science databases were searched from inception to September 2015 in accordance with PRISMA guidelines to identify original peer-reviewed articles describing any findings relating to alcohol and/or illicit drug use among refugees, internally displaced people (IDPs), asylum seekers, people displaced by disasters and deportees. A descriptive synthesis of evidence from quantitative studies was conducted, focusing primarily on studies which used validated measures of substance use. Synthesis of evidence from qualitative studies focused on identifying prominent themes relating to the contexts and consequences of substance use. Critical Appraisal Skills Programme (CASP) checklists were used to assess methodological quality of included studies. Results Forty-four quantitative (82% cross-sectional), 16 qualitative and three mixed-methods studies were included. Ten studies were rated as high methodological quality (16%), 39 as moderate quality (62%) and 14 as low quality (22%). The majority of research was conducted among refugees, IDPs and asylum seekers (n = 55, 87%), predominantly in high-income settings. The highest-quality prevalence estimates of hazardous/harmful alcohol use ranged from 17%-36% in camp settings and 4%-7% in community settings. Few studies collected validated measures of illicit drug use. Seven studies compared substance use among forced migrants to other migrant or native-born samples. Among eight studies which conducted multivariable analysis, male sex, trauma exposure and symptoms of mental illness were commonly identified correlates of substance use. Conclusion Our understanding of substance use among forced migrants remains limited, particularly regarding persons displaced due to disasters, development and deportation. Despite a growing body of work among refugee-background populations, few studies include refugees in low and middle-income countries, where over 80% of the global refugee population resides. Findings suggest a need to integrate substance use prevention and treatment into services offered to forced migrants, particularly in camp settings. Efforts to develop and evaluate interventions to reduce substance use and related harms are needed.

BACKGROUND a growing body of literature has highlighted the prevalence of mistreatment that women experience around the globe during childbirth, including verbal and physical abuse, neglect, lack of support, and disrespect. Much of this has been qualitative. Research around the world suggests that support during childbirth can improve health outcomes and behaviours, and improve experiences. Support can be instrumental, informational, or emotional, and can be provided by a variety of people including family (husbands, mothers) or health providers of various professional levels. This study explores womens reported experiences of mistreatment during childbirth quantitatively, and how these varied by specific types of support available and provided by specific individuals. METHODS participants were women age 16-30 who had delivered infants in a health facility in the previous five years and were living in slums of Lucknow India. Data were collected on their experiences of mistreatment, the types of support they received, and who provided that support. RESULTS women who reported lack of support were more likely to report mistreatment. Lack of support in regards to discussions with providers and provider information were most strongly associated with a higher mistreatment score. Women who received any type of support from their husband or a health worker were significantly more likely to report lower mistreatment scores. Receiving informational support from a mother/mother-in-law or emotional support from a health worker was also associated with lower mistreatment scores. However, receiving emotional support from a friend/neighbour/other family member was associated with a higher mistreatment score. CONCLUSIONS women rely on different people to provide different types of support during childbirth in this setting. Some of these individuals provide specific types of support that ultimately improve a womans overall experience of her childbirth. Interventions aiming to reduce mistreatment to women during childbirth should consider the important role of increasing support for women, and who might be the most appropriate person to provide the most essential types of support through this process.

Dreams deferred: Contextualizing the health and psychosocial needs of undocumented Asian and Pacific Islander young adults in Northern California

May Sudhinaraset; Irving Ling; Tu My To; Jason Melo; Thu Quach

There are currently 1.5 million undocumented Asians and Pacific Islanders (APIs) in the US. Undocumented API young adults, in particular, come of age in a challenging political and social climate, but little is known about their health outcomes. To our knowledge, this is the first study to assess the psychosocial needs and health status of API undocumented young adults. Guided by social capital theory, this qualitative study describes the social context of API undocumented young adults (ages 18-31), including community and government perceptions, and how social relationships influence health. This study was conducted in Northern California and included four focus group discussions (FGDs) and 24 in-depth interviews (IDIs), with 32 unique participants total. FGDs used purposeful sampling by gender (two male and two female discussions) and education status (in school and out-of-school). Findings suggest low bonding and bridging social capital. Results indicate that community distrust is high, even within the API community, due to high levels of exploitation, discrimination, and threats of deportation. Participants described how documentation status is a barrier in accessing health services, particularly mental health and sexual and reproductive health services. This study identifies trusted community groups and discusses recommendations for future research, programs, and policies.

BACKGROUND AND AIM Understanding the experience of initiating injection drug use and its social contexts is crucial to inform efforts to prevent transitions into this mode of drug consumption and support harm reduction. We reviewed and synthesized existing qualitative scientific literature systematically to identify the socio-structural contexts for, and experiences of, the initiation of injection drug use. METHODS We searched six databases (Medline, Embase, PsychINFO, CINAHL, IBSS and SSCI) systematically, along with a manual search, including key journals and subject experts. Peer-reviewed studies were included if they qualitatively explored experiences of or socio-structural contexts for injection drug use initiation. A thematic synthesis approach was used to identify descriptive and analytical themes throughout studies. RESULTS From 1731 initial results, 41 studies reporting data from 1996 participants were included. We developed eight descriptive themes and two analytical (higher-order) themes. The first analytical theme focused on injecting initiation resulting from a social process enabled and constrained by socio-structural factors: social networks and individual interactions, socialization into drug-using identities and choices enabled and constrained by social context all combine to produce processes of injection initiation. The second analytical theme addressed pathways that explore varying meanings attached to injection initiation and how they link to social context: seeking pleasure, responses to increasing tolerance to drugs, securing belonging and identity and coping with pain and trauma. CONCLUSIONS Qualitative research shows that injection drug use initiation has varying and distinct meanings for individuals involved and is a dynamic process shaped by social and structural factors. Interventions should therefore respond to the socio-structural influences on injecting drug use initiation by seeking to modify the contexts for initiation, rather than solely prioritizing the reduction of individual harms through behavior change.

Cross-border ties and the reproductive health of India's internal migrant women

May Sudhinaraset; Jason Melo; Nadia Diamond-Smith

The literature on how social ties influence sexual and reproductive health is well established; however, one significant limitation of this research is the influence of social ties to hometowns among migrant women. Drawing from cross-border social ties literature, the objective of this study is to assess how cross-border social ties influence use of family planning and institutional deliveries among internal migrant women in India. Cross-sectional data come from 711 migrant women living in slums in Uttar Pradesh, India. Multivariable logistic regression was used to assess odds of modern use of family planning and odds of institutional deliveries with cross-border tie indicators. Results suggest that higher cross-border ties were associated with 2.35 times higher odds of family planning use (p<0.1) and 2.73 times higher odds of institutional delivery (p<0.05). This study suggests that social ties to hometowns may serve as a protective factor, possibly through increased social support, to migrants in regards to reproductive decision-making and use of reproductive health services. Future studies should explore potential mechanisms for these findings.

Injection Drug Use Trajectories among Migrant Populations: A Narrative Review

Jason Melo; Maria Luisa Mittal; Danielle Horyniak; Steffanie A. Strathdee; Dan Werb

ABSTRACT Background: Dual epidemics of injection drug use and blood-borne disease, characterized as “syndemics,” are present in a range of settings. Behaviors that drive such syndemics are particularly prevalent among mobile drug-using populations, for whom cross-border migration may pose additional risks. Objectives: This narrative review aims to characterize the risk factors for injection drug use initiation associated with migration, employing a risk environment framework and focusing on the San Diego–Tijuana border region as the most dynamic example of these phenomena. Methods: Based on previous literature, we divide migration streams into three classes: intra-urban, internal, and international. We synthesized existing literature on migration and drug use to characterize how mobility and migration drive the initiation of injection drug use, as well as the transmission of hepatitis and HIV, and to delineate how these might be addressed through public health intervention. Results: Population mixing between migrants and receiving communities and the consequent transmission of social norms about injection drug use create risk environments for injection drug use initiation. These risk environments have been characterized as a result of local policy environments, injection drug use norms in receiving communities, migration-related stressors, social dislocation, and infringement on the rights of undocumented migrants. Conclusion: Policies that exacerbate risk environments for migrants may inadvertently contribute to the expansion of epidemics of injection-driven blood-borne disease. Successful interventions that address emerging syndemics in border regions may therefore need to be tailored to migrant populations and distinguish between the vulnerabilities experienced by different migration classes and border settings.

INTRODUCTION AND AIMS Efforts to prevent injection drug use (IDU) are increasingly focusing on the role that people who inject drugs (PWID) play in facilitating the entry of others into this behaviour. This is particularly relevant in settings experiencing high levels of IDU, such as Mexicos northern border region, where cross-border migration, particularly through forced deportation, has been found to increase a range of health and social harms related to injecting. DESIGN AND METHODS PWID enrolled in a prospective cohort study in Tijuana, Mexico, since 2011 were interviewed semi-annually, which solicited responses on their experiences initiating others into injecting. Univariate and multivariable logistic regression analyses were conducted at the Preventing Injection by Modifying Existing Responses (PRIMER) baseline, with the dependent variable defined as reporting ever initiating others into injection. The primary independent variable was lifetime deportation from the USA to Mexico. RESULTS Among 532 participants, 14% (n = 76) reported initiating others into injecting, the majority of participants reporting initiating acquaintances (74%, n = 56). In multivariable analyses, initiating others into injecting was independently associated with reporting living in the USA for 1-5 years [adjusted odds ratio (AOR) = 2.42; 95% confidence interval (CI) 1.22-4.79, P = 0.01], and methamphetamine and heroin injection combined (AOR = 3.67; 95% CI 1.11-12.17, P = 0.03). Deportation was not independently associated with initiating others into injecting. DISCUSSION AND CONCLUSIONS The impact of migration needs to be considered within binational programming seeking to prevent the expansion of epidemics of injecting and HIV transmission among mobile populations residing in the Mexico-USA border region.

BACKGROUND The prevention of drug injecting is often cited as a justification for the deployment of law enforcement and for the continuation of drug criminalization policies. We sought to characterize the impact of law enforcement interactions on the risk that people who inject drugs (PWID) report assisting others with injection initiation in three North American countries. METHODS Cross-sectional data from PWID participating in cohort studies in three cities (San Diego, USA; Tijuana, Mexico; Vancouver, Canada) were pooled (August 2014-December 2016). The dependent variable was defined as recently (i.e., past six months) providing injection initiation assistance; the primary independent variable was the frequency of recent law enforcement interactions, defined categorically (0 vs. 1 vs. 2-5 vs. ≥6). We employed multivariable logistic regression analyses to assess this relationship while controlling for potential confounders. RESULTS Among 2122 participants, 87 (4.1%) reported recently providing injection initiation assistance, and 802 (37.8%) reported recent law enforcement interactions. Reporting either one or more than five recent interactions with law enforcement was not significantly associated with injection initiation assistance. Reporting 2-5 law enforcement interactions was associated with initiation assistance (Adjusted Odds Ratio=1.74, 95% Confidence Interval: 1.01-3.02). CONCLUSIONS Reporting interactions with law enforcement was not associated with a reduced likelihood that PWID reported initiating others into injection drug use. Instead, we identified a positive association between reporting law enforcement interactions and injection initiation assistance among PWID in multiple settings. These findings raise concerns regarding the effectiveness of drug law enforcement to deter injection drug use initiation.
