The disappearance of migrants, which has reached preoccupying high numbers in recent decades, is related both to the particular vulnerability of migrants traversing dangerous migratory routes and to the high degree of impunity that characterizes investigation and search efforts required. This article argues that the disappearance of migrants at the hands of non-state actors in contexts of systematic impunity and in situations where the state had knowledge or should have had knowledge of a serious risk of such disappearance, but failed to act to prevent it, can be considered to have occurred with the acquiescence of the state. Thus, given that all further elements of the definition of enforced disappearance have been satisfied, this factual situation qualifies as an “enforced disappearance” for the purposes of international human rights law. Key to this demonstration is the concept of knowledge, which is an essential component of acquiescence. This article not only addresses the normative framework of acquiescence and its interpretation by international and regional human rights bodies, including how it relies on the element of state knowledge, but it also examines the extent to which this factor is critical to understanding states’ due diligence obligations to prevent, investigate, and sanction human rights obligations, including disappearances. In order to better understand the factors that should be taken into consideration while assessing a state‘s knowledge of migrant disappearances, including in the context of systematic impunity, it is then suggested to borrow from the international criminal law test related to the concept of “constructive knowledge” and to the doctrine of command responsibility. These considerations should inform a test for assessing whether disappearances of migrants occurring in contexts of systematic impunity can be considered as having been known by the state and as having occurred with its acquiescence and, thus, as constituting “enforced disappearances” under international human rights law.

Migrants and refugees face elevated risks for mental health problems but have limited access to services. This study compared two strategies for training and supervising nonspecialists to deliver a scalable psychological intervention, Group Problem Management Plus (gPM+), in northern Colombia. Adult women who reported elevated psychological distress and functional impairment were randomized to receive gPM+ delivered by nonspecialists who received training and supervision by: 1) a psychologist (specialized technical support); or 2) a nonspecialist who had been trained as a trainer/supervisor (nonspecialized technical support). We examined effectiveness and implementation outcomes using a mixed-methods approach. Thirteen nonspecialists were trained as gPM+ facilitators and three were trained-as-trainers. We enrolled 128 women to participate in gPM+ across the two conditions. Intervention attendance was higher in the specialized technical support condition. The nonspecialized technical support condition demonstrated higher fidelity to gPM+ and lower cost of implementation. Other indicators of effectiveness, adoption and implementation were comparable between the two implementation strategies. These results suggest it is feasible to implement mental health interventions, like gPM+, using lower-resource, community-embedded task sharing models, while maintaining safety and fidelity. Further evidence from fully powered trials is needed to make definitive conclusions about the relative cost of these implementation strategies.

The ways in which minority street-level bureaucrats construe their identities as state representatives and as representatives of minority clients are known to inform their discretionary behavior toward clients, thereby shaping policy outcomes. While existing studies have examined race and ethnicity as shared identities between minority bureaucrats and clients, the role of “migrant” identity has been overlooked. Focusing on the so-called European migration crisis of 2015–2017, this study addresses this gap. Drawing on qualitative interviews with migrant bureaucrats, it examines how being simultaneously a migrant and a migration policy implementer shapes bureaucratic discretion. This article introduces the notion of “migrant representative” and identifies four profiles of migrant bureaucrats, each corresponding to different degrees of identification with the local migration management system and the migrant clients. In doing so, it contributes to the literature on representative bureaucracy and the debate on the linkage between passive and active representation.

This article analyses the scholarly results concerning the social phenomenon of intermarriage. It specifically focuses on the similarities and differences in the latter in Europe, between migrants and host society members, and between national minorities and majorities. The study shows that while intermarriage between migrants and host society members is often seen as a vehicle for bridging social gaps and promoting social cohesion, intermarriages between national minorities and majorities is more likely to lead to erosion of minority identities and cultural traits. Common challenges faced by intermarried couples include resistance from family members and bureaucratic obstacles, with gender dynamics playing a crucial role, particularly in traditional societies where women often bear the brunt of cultural assimilation. Intermarriage also promotes the perspective of the integrative nature of nation-states without requiring intervention by the states themselves. The article underscores the importance of deepening the discourse on intermarriage and focusing on the impact of the latter on both migrant and national minority communities through both quantitative analyses and qualitative approaches. This may improve the understanding of the transformative potential and challenges of these unions.

Poland remained a popular destination for migrants from Ukraine for many years before February 24, 2022, the outbreak of full-scale Russian aggression on Ukraine. Ukrainian communities in Polish cities, including local autochthonous Ukrainians (the Ukrainian national minority), are already well-established and well-organized, although they are very diverse. Drawing from anthropological fieldwork conducted in 2021 and at the beginning of 2022, this article seeks to address the nexus of the diaspora and culture and explores the imaginations of “common culture” in diaspora-forming processes. We treat “culture” as diasporic imaginings of naturalized and reified representations of what is to be a Ukrainian in Poland. The essentialized notion of putative “common culture” is routinely discursivized and maintained by diasporic elites. Exploring this as an empirical phenomenon captured in the field helps reveal the internal tensions and that this imagining empowers the production of cultural differences. We argue that imagined “common culture” may actually activate “othering” of the diasporic Other and might not be as unifying a factor in diaspora-forming processes as it appears.

Migrant mental health is a pressing public health issue with wide-ranging implications. Many randomized controlled trials (RCTs) have been conducted in this population to assess the effects of psychosocial interventions. However, the available evidence is characterized by controversy and fragmentation, with studies focusing on different migrant populations, interventions, outcomes, delivery modalities and settings. Aiming to promote systematic reviews of the effectiveness of psychosocial interventions in different migrant groups, we have developed a living database of existing RCTs. The development of the database provides an opportunity to map the existing RCT evidence in this population. A total of 135 studies involving 24,859 participants were included in the living database. The distribution of studies by year of publication aligns with the increasing global migrant population in recent years. Most studies focus primarily on adult participants, with a limited representation of children and adolescents, and a prevalence of female participants, which is consistent with epidemiological data, except for older adults, who are underrepresented in research. Studies predominantly focus on refugees and asylum seekers, likely due to their elevated risk of mental health issues, despite the substantial presence of economic migrants worldwide. While studies mainly involve migrants from the Middle East and East Asia, epidemiological data suggest a broader geographic representation, with migrants coming from Eastern Europe, Latin America and South Asia. The present descriptive analysis of RCTs on mental health and psychosocial interventions for migrant populations provides valuable insights into the existing research landscape. It should be used to inform future research efforts, ensuring that studies are more representative of the global migrant population and more responsive to the mental health needs of migrants in different contexts.

Meta-analysis is used to test a variant of a Developmental Origins of Adult Health and Disease (DOHaD)’s conjecture known as predictive adaptive response (PAR). According to it, individuals who are exposed to mismatches between adverse or constrained in utero conditions, on the one hand, and postnatal obesogenic environments, on the other, are at higher risk of developing adult chronic conditions, including obesity, type 2 diabetes (T2D), hypertension and cardiovascular disease. We argue that migrant populations from low and middle to high-income countries offer a unique opportunity to test the conjecture. A database was constructed from an exhaustive literature search of peer-reviewed papers published prior to May 2021 contained in PUBMED and SCOPUS using keywords related to migrants, DOHaD, and associated health outcomes. Random effects meta-regression models were estimated to assess the magnitude of effects associated with migrant groups on the prevalence rate of T2D and hypertension in adults and overweight/obesity in adults and children. Overall, we used 38 distinct studies and 78 estimates of diabetes, 59 estimates of hypertension, 102 estimates of overweight/obesity in adults, and 23 estimates of overweight/obesity in children. Our results show that adult migrants experience higher prevalence of T2D than populations at destination (PR 1.48; 95% CI 1.35–1.65) and origin (PR 1.80; 95% CI 1.40–2.34). Similarly, there is a significant excess of obesity prevalence in children migrants (PR 1.22; 95% CI 1.04–1.43) but not among adult migrants (PR 0.89; 95% CI 0.80–1.01). Although the total effect of migrant status on prevalence of hypertension is centered on zero, some migrant groups show increased risks. Finally, the size of estimated effects varies significantly by migrant groups according to place of destination. Despite limitations inherent to all meta-analyses and admitting that some of our findings may be accounted for alternative explanations, the present study shows empirical evidence consistent with selected PAR-like conjectures.

The non-take-up of public services has the potential to undermine civil rights and deepen social inequality. Looking at the case of the Youth Community College Programme in China, an innovation in governance to facilitate community integration of the migrant population by providing free education, this study finds that the targeted disadvantaged groups are systematically excluded due to the disproportionate imposition of various administrative burdens on them. We propose that an interaction mechanism – which we term “selective affinity” – between the policy process and individuals’ human capital leads to this unintended outcome. The study contributes to a deeper understanding of the causal mechanisms underlying vulnerable people's non-take-up of public services, while highlighting an example of dysfunctional state–society interaction and a mechanism for the reproduction of social inequality under authoritarianism in China.

More than three in 10 people living in Jordan are immigrants, with the majority being Palestinian and Syrian refugees, who have a very similar non-communicable diseases (NCDs) profile to the hosting Jordanian community. We conducted a rapid review of the literature of studies, reports, and documents on the evidence of the impact of COVID-19 on vulnerable populations in Jordan with regard to NCD during the first year of the pandemic. COVID-19-related mobility constraints and often lack of awareness of NCDs put additional burden on vulnerable populations like refugees and migrants, in particular on non-registered migrants. COVID-19 pandemic and associated mitigation measures led to disruption in routine health services, significantly impacting people living with NCDs. Ensuring to deliver a people-centered and inclusive approach that works well during COVID-19 is of paramount importance toward Universal Health Coverage (all people have access to the health services they need, when and where they need them, without financial hardship).

The COVID-19 pandemic has had negative consequences on the mental health of the population, which has been documented. Marginalised groups that are at risk of poor mental health overall have been particularly impacted. The purpose of this review is to describe the mental health impact of the COVID-19 pandemic on marginalised group (i.e. persons who are socio-economically disadvantaged, migrants and members of ethno-racial minorities, experience homelessness) and identified interventions which could be well-suited to prevent and address mental health difficulties. We conducted a literature review of systematic reviews on mental health difficulties since the beginning of the COVID-19 epidemic and appropriate interventions among marginalised groups published from January 1, 2020 to May 2, 2022, using Google Scholar and PubMed (MEDLINE). Among 792 studies on mental health difficulties among members of marginalised groups identified by keywords, 17 studies met our eligibility criteria. Twelve systematic reviews examining mental health difficulties in one or several marginalised groups during the COVID-19 pandemic and five systematic reviews on interventions that can mitigate the mental health impact of the COVID-19 pandemic were retained in our literature review. The mental health of marginalised groups was severely affected during the COVID-19 pandemic. Most frequently reported mental health difficulties included symptoms of anxiety and depression. Additionally, there are interventions that appear effective and well-suited for marginalised populations, which should be disseminated on a large scale to mitigate the psychiatric burden in these groups and at the population level.
