Attachment style and changes in systemic inflammation following migration to a new country among international students

Psychosocial and neurobiological aspects of the worldwide refugee crisis: From vulnerability to resilience

Anisman, H., Doubad, D., Asokumar, A. & Matheson, K. Psychosocial and neurobiological aspects of the worldwide refugee crisis: From vulnerability to resilience. NEUROSCI BIOBEHAV REV, XXXX. Immigration occurs between countries either to obtain employment, for family reunification or to escape violence and other life-threatening conditions. Refugees and asylum seekers are often obligated to overcome a uniquely challenging set of circumstances prior to and during migration. Settlement following immigration may pose yet another set of stressors related to acculturation to the host country, as well as financial insecurity, discrimination, language barriers, and social isolation. Here we discuss the multiple consequences of immigration experiences, focusing on the health disturbances that frequently develop in adults and children. Aside from the psychosocial influences, immigration-related challenges may cause hormonal, inflammatory immune, and microbiota changes that favor psychological and physical illnesses. Some biological alterations are subject to modification by epigenetic changes, which have implications for intergenerational trauma transmission, as might disruptions in parenting behaviors and family dysfunction. Despite the hardships experienced, many immigrants and their families exhibit positive psychological adjustment after resettlement. We provide information to diminish the impacts associated with immigration and offer strength-based approaches that may foster resilience.

Exploring homesickness among international students in China during border closure

It is nearly three years since the World Health Organization (WHO) declared the COVID-19 crisis as a pandemic. Since its inception, border closures have been subscribed to by many countries as an extreme policy tool to curb the rate of infection amid emerging variants. China, one of the earliest countries to implement this measure just opened its borders to international students for inbound and outbound travel with several preconditions. Homesickness, a grave discomfort because of its cognitive hallmark of destabilizing the affective states and routine activities of individuals has been underexplored in many studies on the COVID-19 impact on education. This phenomenological study is the first to explore the level of border-closure-induced homesickness among international students in an Asian context (China). International students (n = 20) sampled from five universities in China were interviewed on how the COVID-19-engineered border closures have prompted homesickness among them and their development of coping skills. The thirteen (13) themes that emerged from the study suggest that the students suffered from somatic and psychological symptoms of homesickness. The social and academic life of students were negatively affected. Participants in the study relied on frequent phone calls, entertainment, and indoor and outdoor activities such as exercise and campus excursions as coping strategies against homesickness. It is advocated that higher education leaders in China put in measures to hasten the acculturation of international students to minimize their homesickness. Further research areas such as taking a keen focus on maladaptive symptoms of homesickness are also discussed.

Do Migration and Acculturation Impact Somatization? A Scoping Review

Somatization is a phenomenon in which the individual experiences physical symptoms attributable to mental projections. It is a widely used term in common parlance to figuratively describe a stressful situation. Syndromes directly related to the mind have been described; pathologies are influenced by somatization. However, the extent of somatization is also related to social and cultural factors. In fact, each culture expresses varying levels of somatization characteristic of the country of origin. A disease can even manifest with different symptoms in different ethnic groups. The migration process arises from the need for change on the part of those who undertake it and culminates in the integration of the person in the host country. This process induces changes in the person of a psychological nature, which also affects somatization. In fact, the most integrated subjects show levels of somatization comparable to those of the host country. These considerations support the thesis that psychological changes are an integral part of health and can affect the development of organic and somatized pathologies.

Rethinking minority stress: A social safety perspective on the health effects of stigma in sexually-diverse and gender-diverse populations

For over two decades, the minority stress model has guided research on the health of sexually-diverse individuals (those who are not exclusively heterosexual) and gender-diverse individuals (those whose gender identity/expression differs from their birth-assigned sex/gender). According to this model, the cumulative stress caused by stigma and social marginalization fosters stress-related health problems. Yet studies linking minority stress to physical health outcomes have yielded mixed results, suggesting that something is missing from our understanding of stigma and health. Social safety may be the missing piece. Social safety refers to reliable social connection, inclusion, and protection, which are core human needs that are imperiled by stigma. The absence of social safety is just as health-consequential for stigmatized individuals as the presence of minority stress, because the chronic threat-vigilance fostered by insufficient safety has negative long-term effects on cognitive, emotional, and immunological functioning, even when exposure to minority stress is low. We argue that insufficient social safety is a primary cause of stigma-related health disparities and a key target for intervention.

Impact of the COVID‐19 pandemic on inflammatory bowel disease: The role of emotional stress and social isolation

Inflammatory bowel disease (IBD) is a chronic health condition exacerbated by negative emotional stress experiences. In the current study, we examined whether the outbreak of the COVID-19 pandemic coincided with an increase in stress experiences and accordingly an aggravation of disease activity in IBD patients. Sixty-three IBD patients (30 Crohn's disease or CD, 33 ulcerative colitis) completed an online survey during the COVID-19-related lockdown, assessing clinical disease activity, disease-related quality of life, presence of functional gastrointestinal symptoms, social isolation and stress experiences. Scores were then compared to pre-lockdown baseline screening. The pandemic yielded a significant baseline-to-lockdown increase in emotional stress and social isolation. Stress increments, particularly those occasioned by interpersonal tension and excessive interpersonal proximity, were associated with a worsening of functional gastrointestinal symptoms. Exacerbations of loneliness coincided with an escalation of CD activity, functional gastrointestinal symptoms and a decline in subjective health. Lastly, COVID-19 anxiety was significantly related to CD symptom severity and social dysfunction. The findings show that shifts in IBD expression are closely linked to changes in emotional stress experiences and interpersonal relatedness. As such, they contribute to a better understanding of inter-individual differences in IBD progression and provide leads for therapeutic interventions.

Immune and Epigenetic Pathways Linking Childhood Adversity and Health Across the Lifespan

Childhood adversity is associated with a host of mental and physical health problems across the lifespan. Individuals who have experienced childhood adversity (e.g., child abuse and neglect, family conflict, poor parent/child relationships, low socioeconomic status or extreme poverty) are at a greater risk for morbidity and premature mortality than those not exposed to childhood adversity. Several mechanisms likely contribute to the relationship between childhood adversity and health across the lifespan (e.g., health behaviors, cardiovascular reactivity). In this paper, we review a large body of research within the field of psychoneuroimmunology, demonstrating the relationship between early life stress and alterations of the immune system. We first review the literature demonstrating that childhood adversity is associated with immune dysregulation across different indices, including proinflammatory cytokine production (and its impact on telomere length), illness and infection susceptibility, latent herpesvirus reactivation, and immune response to a tumor. We then summarize the growing literature on how childhood adversity may alter epigenetic processes. Finally, we propose future directions related to this work that have basic and applied implications.

Acculturation and biological stress markers: A systematic review

BACKGROUND

The association of acculturation with health among immigrant populations is believed to be mediated, in part, by acculturation-related stress and stress biology.

OBJECTIVES

To review and qualitatively synthesize empirical findings on the relationship of acculturation with stress-related inflammatory and endocrine biomarkers and composite allostatic load (AL) scores.

METHODS

A literature search was performed in the PubMed and PsycInfo databases. Article titles, abstracts or full-texts were screened and checked for match with the search criteria. Studies were eligible if they empirically tested the relationship between acculturation and inflammatory/endocrine stress biomarkers or composite AL scores, and were published in the English language.

RESULTS

Among the 41 articles identified as relevant and included in this review, the majority were published after 2010, included adult Hispanic U.S.-based populations, used cross-sectional study designs, operationalized acculturation as a unidimensional construct, and varied considerably in the selection of covariates in the analyses. Acculturation was significantly associated with stress biomarkers in 29 studies, but the direction of effects varied across studies. Specifically, acculturation, operationalized as a higher orientation towards the host culture, was associated with inflammatory biomarkers in 10 of 14 studies, with endocrine stress biomarkers in 12 of 20 studies, and with composite AL scores in 7 of 8 studies. Overall, language-based proxy measures of acculturation were related to higher levels of stress-related inflammatory and endocrine biomarkers and to lower levels of AL scores, whereas nativity-, generation status- and length of stay-based proxy measures of acculturation were related to higher levels of inflammatory biomarkers and AL score.

DISCUSSION

The majority of studies reported associations between measures of acculturation and stress biomarkers, however the directions of effects varied across studies. We suggest this heterogeneity may, in part, be a function of limitations imposed by cross-sectional research designs and unidimensional measures of acculturation measures, and we highlight the need for longitudinal studies and use of multidimensional measures of acculturation to better uncover the biobehavioral mechanisms and pathways linking acculturation with health outcomes.

Individual differences in attachment anxiety shape the association between adverse childhood experiences and adult somatic symptoms

BACKGROUND

Although prior research has documented the link between adverse childhood experiences (ACEs) and somatic symptoms, it remains unclear why some individuals exposed to ACEs developed somatic symptoms while others did not.

OBJECTIVE

Framed by a biopsychosocial perspective, this study investigated the role of attachment anxiety in the association between ACEs and somatic symptoms in adulthood.

PARTICIPANTS AND SETTING

A total of 662 emerging adults attending college were recruited to respond to an online survey in a computer lab.

METHOD

The computer-based survey included demographic form, the Adverse Childhood Experience Scale, the Experience in Close Relationship Scale-Short Form, and the Somatization Scale of the Symptom Checklist-90-Revised for somatic symptoms. Multivariate regression analyses were used to examine the role of attachment anxiety in the association between ACEs and somatic symptoms.

RESULTS

The results indicated that ACEs positively correlated with attachment anxiety and somatic symptoms; and attachment anxiety and somatic symptoms were positively correlated. Moreover, the results indicated a significant effect of interaction between ACEs and attachment anxiety on somatic symptoms, suggesting a moderating role of attachment anxiety. Subsequent simple slope test revealed that attachment anxiety intensified the strength of relation between ACEs and somatic symptoms; but when the level of attachment anxiety was low, ACEs and somatic symptoms were not related.

CONCLUSION

Individual differences in attachment anxiety shape the association of adverse childhood experiences with somatic symptoms. Targeting and reformulating anxious working models of attachment may help ameliorate vulnerability to somatic symptoms in individuals exposed to ACEs.

Attachment and physical health: introduction to the special issue

Over the last 40 years, researchers have made considerable progress identifying the ways in which attachment security shapes individuals' social and emotional functioning. In recent years, new investigations have shed light on connections between attachment and physiological systems in the body. The goal of this special issue is to focus attention on how attachment may be related to biological markers that relate to physical health, including inflammation, cortisol, and cardiometabolic risk. The papers in this special issue, highlighted in this introduction, demonstrate that these links may exist across the lifespan. We conclude with several examples of extensions of this work might emerge in the years to come.
