Suicide among migrants: a comprehensive narrative review of literature.

Suicidality among migrants represents a multifaceted and complex issue with significant implications and challenges for public mental health and policies. This narrative review aims to explore the factors contributing to suicidality within the migrant groups, consequently highlighting the need for tailored interventions and supporting strategies. Firstly, we reviewed the evidences on the prevalence of suicidal ideation, attempted suicides, and deaths by suicide among migrants. The results were extremely heterogeneous, mostly depending on the different migrant group considered. Significant differences in suicide risk have been found depending on the legal status of migrants and their country of origin/migration. The second section explored the protective and risk factors for suicidal ideation and behaviours in different migrant groups. The analysis concluded that a set of factors may interact in various ways, contributing to a heterogeneous and complex framework underpinning the phenomenon of suicide. Migration itself may be a challenging and traumatizing experience, characterized by social isolation, cultural dislocation and adjustment, as well as economic and financial distress, all of which may exacerbate pre-existing mental health vulnerabilities or trigger new mental disorders. Acculturative stress, discrimination, and language barriers further compound these challenges, often hindering access to mental health services.

The prevalence of suicidal ideation and behaviour among migrant populations consistently varies across studies, mostly depending on the different characteristics of the various subgroups of migrants sampled.Literature comparing suicide risk among migrants and the native populations of the host countries has shown contrasting findings.Some studies have suggested that refugees report a higher risk of suicide compared to the general population but also to other migrant groups.Studies focused on asylum seekers have suggested that this group reports a particularly higher suicide risk than the native population of the hosting country.Migrants seem to carry with them the suicide risk rate registered in their homeland. In fact, migrants from countries with a high baseline suicide rate (i.e. Northern and Eastern European countries) are at higher risk of suicide attempts and death by suicide; nonetheless, over time, their risk rates tend to overlap with those of the country of migration.Factors that protect or predispose individuals to suicidality may differ between ethnic groups.Conflicts and war-related traumatic experiences, irrespectively of the presence of mental disorders, are common risk factors for suicidal ideation among refugees.Research suggests that second-generation migrants are more likely to exhibit suicidal behaviors compared to first-generation migrants.Migrant mothers may be a particularly vulnerable group, as they are less likely to seek help from professional services due to various barriers, including stigma, language, poor knowledge of community services, and prioritizing their children's needs.Poor living conditions are associated with an increased prevalence of mental disorders and suicidal behaviour among migrants. Concerns about safety and lack of shelter, food, water, clothing, and toilets were all associated with higher rates of PTSD symptoms and suicidal ideation.Migrants face several challenges in accessing mental health treatments, including stigma, language barriers and distrust due to the lack of cultural-competent and gender-sensitive assistance.

Lifestyles and Quality of Life of People with Mental Illness During the COVID-19 Pandemic.

The COVID-19 pandemic has had a significant impact on the quality of life (QoL), daily lifestyle, and mental health of people suffering from a mental disorder. This study aimed to investigate the effects of the prolongation of the COVID-19 emergency on QoL and lifestyles in a sample of 100 outpatients at the Psychiatry Unit in Palermo University Hospital, Italy. QoL was measured through the 12-item Short Form Survey and the COV19-Impact on Quality of Life. Lifestyle changes during the pandemic were measured through the lifestyle change questionnaire. The majority of participants reported a great impact of COVID-19 on the QoL, and almost half reported worsened lifestyles. Worsened lifestyles were predictive of both poor mental and physical health related QoL. These results suggest that people with mental illness need interventions targeting lifestyles, and the mental health service in Italy should adjust to the ongoing pandemic, developing virtual treatments.

The relationship between genetic liability, childhood maltreatment, and IQ: findings from the EU-GEI multicentric case-control study.

This study investigated if the association between childhood maltreatment and cognition among psychosis patients and community controls was partially accounted for by genetic liability for psychosis. Patients with first-episode psychosis (N = 755) and unaffected controls (N = 1219) from the EU-GEI study were assessed for childhood maltreatment, intelligence quotient (IQ), family history of psychosis (FH), and polygenic risk score for schizophrenia (SZ-PRS). Controlling for FH and SZ-PRS did not attenuate the association between childhood maltreatment and IQ in cases or controls. Findings suggest that these expressions of genetic liability cannot account for the lower levels of cognition found among adults maltreated in childhood.

Childhood Maltreatment, Educational Attainment, and IQ: Findings From a Multicentric Case-control Study of First-episode Psychosis (EU-GEI).

BACKGROUND AND HYPOTHESIS: Evidence suggests that childhood maltreatment (ie, childhood abuse and childhood neglect) affects educational attainment and cognition. However, the association between childhood maltreatment and Intelligence Quotient (IQ) seems stronger among controls compared to people with psychosis. We hypothesised that: the association between childhood maltreatment and poor cognition would be stronger among community controls than among people with first-episode of psychosis (FEP); compared to abuse, neglect would show stronger associations with educational attainment and cognition; the association between childhood maltreatment and IQ would be partially accounted for by other risk factors; and the association between childhood maltreatment, educational attainment, and IQ would be stronger among patients with affective psychoses compared to those with nonaffective psychoses. STUDY DESIGN: 829 patients with FEP and 1283 community controls from 16 EU-GEI sites were assessed for child maltreatment, education attainment, and IQ. STUDY RESULTS: In both the FEP and control group, childhood maltreatment was associated with lower educational attainment. The association between childhood maltreatment and lower IQ was robust to adjustment for confounders only among controls. Whereas childhood neglect was consistently associated with lower attainment and IQ in both groups, childhood abuse was associated with IQ only in controls. Among both patients with affective and nonaffective psychoses, negative associations between childhood maltreatment and educational attainment were observed, but the crude association with IQ was only evident in affective psychoses. CONCLUSIONS: Our findings underscore the role of childhood maltreatment in shaping academic outcomes and cognition of people with FEP as well as controls.

The relationship of symptom dimensions with premorbid adjustment and cognitive characteristics at first episode psychosis: Findings from the EU-GEI study.

Premorbid functioning and cognitive measures may reflect gradients of developmental impairment across diagnostic categories in psychosis. In this study, we sought to examine the associations of current cognition and premorbid adjustment with symptom dimensions in a large first episode psychosis (FEP) sample. We used data from the international EU-GEI study. Bifactor modelling of the Operational Criteria in Studies of Psychotic Illness (OPCRIT) ratings provided general and specific symptom dimension scores. Premorbid Adjustment Scale estimated premorbid social (PSF) and academic adjustment (PAF), and WAIS-brief version measured IQ. A MANCOVA model examined the relationship between symptom dimensions and PSF, PAF, and IQ, having age, sex, country, self-ascribed ethnicity and frequency of cannabis use as confounders. In 785 patients, better PSF was associated with fewer negative (B = -0.12, 95% C.I. -0.18, -0.06, p < 0.001) and depressive (B = -0.09, 95% C.I. -0.15, -0.03, p = 0.032), and more manic (B = 0.07, 95% C.I. 0.01, 0.14, p = 0.023) symptoms. Patients with a lower IQ presented with slightly more negative and positive, and fewer manic, symptoms. Secondary analysis on IQ subdomains revealed associations between better perceptual reasoning and fewer negative (B = -0.09, 95% C.I. -0.17, -0.01, p = 0.023) and more manic (B = 0.10, 95% C.I. 0.02, 0.18, p = 0.014) symptoms. Fewer positive symptoms were associated with better processing speed (B = -0.12, 95% C.I. -0.02, -0.004, p = 0.003) and working memory (B = -0.10, 95% C.I. -0.18, -0.01, p = 0.024). These findings suggest that the negative and manic symptom dimensions may serve as clinical proxies of different neurodevelopmental predisposition in psychosis.
