The practice of family separation as a mechanism of oppression has a deep-rooted history in the U.S., manifesting in diverse contexts, including punitive migration policies. This systematic review aimed to provide a rigorous and updated synthesis of the research on family separation as a result of migration policies and its impacts on immigrants\' mental health while making a distinction between forced family separation, family separation by constrained choices, and living with the fear of family separation. We systematically searched four bibliographic databases using keywords related to family separation, migration, transnational families, and mental health for peer-reviewed studies published in English on or before January 1st, 2022. Results of the review indicate that family separation or fear of it may result in depression, anxiety, behavioral and emotional issues, sleep disturbances, and stress or distress in affected children. Similarly, impacted parents or caregivers might experience stress or distress, depression, anxiety, and sleep disturbances. Findings call for migration policy changes prioritizing family unity and comprehensive mental health interventions to respond to the pervasive consequences of family separation or fear thereof among immigrants in the U.S.

The refugee crisis is spreading rapidly, with the number of global refugees this decade doubling in comparison to the last, leading to further concern regarding asylum policies and their psychological impacts. The aim of this systematic review is to further emphasize the correlation between familial separation and the risk of mental health disorders in refugees. This particular review uses quantitative and qualitative data sourced from a variety of countries to comparatively view the mental health status of approximately 8,737 refugees ages 15 and older. This was done to determine if familial separation could potentially impact their overall quality of life. As a result, separation from one\'s family was found to be correlated with symptoms of posttraumatic stress disorder, depression, anxiety, adult separation anxiety disorder, intermittent explosive disorder, and more. Studies reported a high variance in the prevalence of mental health disorders when models were adjusted for family separation. Methods to improve asylum procedure and mental health services for refugees is taken into consideration.

While transnational social ties and exchanges are a core concern within migration studies, health researchers have often overlooked their importance. Continuous and circular exchanges of information within transnational networks, also defined as social remittances, facilitate the diffusion of innovations, potentially driving contemporary social and cultural change. Influences on health, wellbeing, and care-seeking are important, but under-researched, dimensions for consideration. We undertook a systematic narrative evidence synthesis to describe the current state of knowledge in this area and to identify gaps and future directions for health researchers to take. Between April 2017 and May 2019, an iterative series of searches in Medline, Embase, PsycINFO and PubMed, plus backward and forward citation searches identified 1173 potential papers. Screening resulted in 36 included papers, eighteen focused on migrant populations and eighteen on those who remain behind. The top three health topics were health-seeking strategies, sexual and reproductive health issues, and healthcare support. And, while not always explicitly identified, mental health and wellbeing was a further prominent, cross-cutting theme. Articles on migrant populations were all conducted in the global North and 13 out of 18 used qualitative methods. Five main themes were identified: therapeutic effect of the continuing social relationships, disrupted social relationships, hybridisation of healthcare, facilitation of connections to healthcare providers, and factors encouraging or undermining transnational social exchanges. Papers concerned with those who remain behind were mainly focused on the global South and used a mix of qualitative and quantitative approaches. Four main themes were identified: transnational transfer of health-related advice, norms, and support; associations between migrant linkages and health behaviours/outcomes; transnational collective transfer of health knowledge; and power and resistance in exchanges. Findings suggest that transnational social exchanges can both support and undermine the health of migrants and those who remain behind. This review confirms that the volume and quality of research in this area must be increased so that health policy and practice can be informed by a better understanding of these important influences on the health of both migrants and those who remain behind.

Introduction: Despite the research on left-behind children, less is known about left-behind women across transnational spaces. The purpose of this scoping review was to assess the extent, range, and nature of the existing body of literature on left-behind women whose partners have migrated across borders. Method: This scoping review was guided by the five-step approach of Arksey and O\'Malley. Fifty-four articles that focused on left-behind women across transnational spaces were included. Data were synthesized using descriptive statistics and conventional content analysis. Results: Left-behind women were primarily from Mexico (n = 13) and the migrants\' place of destination was primarily the United States (n = 14). We identified two major themes: (a) women\'s social, economic and cultural conditions and (b) women\'s well-being. Discussion: We identified significant knowledge gaps regarding left-behind women in the context of transnational migration. Implications for future research and practice are discussed.
