Grand global challenges significantly impact mental health and well-being in vulnerable populations across the globe. Today, national health systems and infrastructures are often not sufficiently equipped to react effectively to these grand challenges' multiple and interrelated consequences. The World Health Organization has identified 13 urgent health challenges for the upcoming decade (see Table 1). From our perspective, nine of these challenges are crucial not only for global health but also for Global Mental Health.

Table 1. Grand challenges in global (mental) health.

Challenge 1: Health in Conflict and Crisis Settings

Displacement due to conflict (such as in Syria, Yemen, the Central African Republic, Congo, South Sudan) or extreme violence (inflicted upon Rohingya) affected millions of people worldwide. As a direct consequence, the World Migration Report counted 272 million people as migrants (3.5% of the world's population). The global refugee population amounted to 25.9 million. The number of internally displaced people reached 41.3 million (1). These numbers are of relevance for mental health for two reasons: first, a significant proportion of refugees and migrants have been exposed to violence (2) and went through traumatic experiences [(3); Walther et al.] in their home countries or during the flight. Second, after arrival in the receiving countries, refugees, migrants, and asylum seekers experience a variety of postmigration stressors such as unclear legal status, unemployment, the absence of the core family, or the housing situation [(4); Hajak et al.]. These stressors and traumatic experiences before, during, and after flight are likely to impact incidence rates of stress-related (pooled prevalence 29.9%) and posttraumatic disorders [pooled prevalence: 39.8%; (5)].

Challenge 2: Access to Treatment and Medical Services

Thus, it is evident that migrants, refugees, and asylum seekers are overrepresented in clinical populations with mental disorders (6). However, this phenomenon is not restricted to mental health: migrants have a higher likelihood of obesity and are often more likely to live an unhealthier lifestyle [e.g., smoking, (7)]. Against this background, it is mandatory that this vulnerable population is provided with context-sensitive and privileged access to health care facilities. However, the opposite is the case. In many regions of the world, universal health coverage (UHC) paradoxically builds multiple barriers toward and within the health care system for migrants and refugees as one of the most vulnerable groups. In addition, refugees and migrants face additional difficulties such as poor health literacy as well as language and cultural barriers. Therefore, it is surprising that in countries like Germany, migrants have a lower mortality as compared to individuals within the German non-migrant populations (8). Since this observation is likely to be due to a highly selected migrant population, it is essential to develop institutional and procedural strategies to overcome barriers. These strategies are available as illustrated by the example of a central clearing clinic (Bajbouj et al.) and resource-saving stepped and collaborative care models (9).

Challenge 3: Public Trust and Health Literacy

The best health infrastructure and the largest mental health care resources are of no value if affected populations are stigmatized or if no knowledge exists regarding diseases or treatment options on the caretakers' side. Equally important, health literacy needs to be present on the caregivers' side with respect to cultural differences in idioms of distress or concerning culture-sensitive treatment modifications (10, 11). Two examples of interventions considering cultural aspects are in diagnostics (Lindheimer et al.) and therapy (Rayes et al.) are provided in this special issue, as well as insights into the role of stigma in the provision of mental health services in Germany (Lindheimer et al.; Bär et al.), Jordan, and the Kurdistan Region of Iraq (12, 13).

Challenge 4: Health Disparities

Despite the higher risk of developing mental disorders, migrants and refugees seem to be at a significant disadvantage within specialized mental health care with lower rates of hospitalization, the lower likelihood for referral to mental health specialists, and higher rates of treatment discontinuation (14, 15) as well as shorter treatment duration of inpatients in psychiatric wards (Frizi et al.). The phenomenon of health disparities in health systems is universal, not specific to mental health care and general drivers of inequity such as socioeconomic status, neighborhood, and insurance status can potentially impact all medical disciplines (16).

Challenge 5: Mental Health Care in Pandemics

The current COVID-19 pandemics have deciphered difficulties in accessing health structures, lack of public trust, and health disparities in mental health care across the globe. The pandemic served as an acute stressor for health systems and their health workers, as illustrated in quantitative and qualitative studies from Tunisia (Slama et al.), Kenya (Kwobah et al.), Pakistan (Ali et al.), and Switzerland (Weilenmann et al.). Importantly, the pandemic-related stress in healthcare workers has both short-term and considerable long-term effects on the incidence of affective and posttraumatic stress disorders (Waring and Giles). But pandemics impact mental health beyond health care workers. Beyond them, COVID-19 patients and their relatives experience high anxiety levels (Dorman-Ilan et al.). These effects seem to be pronounced in vulnerable populations such as migrants (Moran et al.) or with adverse childhood experiences (Huang et al.). For those beneficiaries, but also for health care professionals, various low-threshold interventions had been suggested to overcome such pandemic-related stress, including very basic psychosocial interventions such as exercise, mindfulness practices, religious practices, or social engagement that are preferably applied in group settings (Mashaphu et al.; Maric et al.).

Challenge 6: Health and Climate Crisis

There is increasing evidence that climate change does have direct and indirect effects on mental health. Direct effects comprise phenomenons such as eco-anxiety or exacerbation of existing severe mental disorders by adverse environmental factors (17). Indirect effects are due to the socioeconomic impacts of climate change which in turn constitute risk factors for a variety of psychiatric syndromes and disorders such as suicidality, affective disorders, or addiction (18).

Challenge 7: New Technologies

Across the globe, there is a need for health care strengthening and a need to address the psychological needs of patients with mental disorders (19). New technologies may provide the opportunity to overcome these by connecting beneficiaries of low- and middle-income countries to experts in better-positioned regions of the world, by broadly providing health literacy programs, low threshold interventions (20), or by educating health care workers (see challenge 8). On the other hand, new digital technologies pose a risk of substituting evidence-based mental health interventions and promoting less rigorously evaluated treatments for persons living in LMICs.

Challenge 8: Education of Health Workers

Treatment of patients with mental disorders needs relevant, and thus context adapted human capacities in the mental health sector. To strengthen mental health systems, especially in LMICs, awareness in policymakers and planners (21) is required as well as structured training programs for mental health care providers. An evident approach to addressing this medical need is to increase the capacity to train experts of different disciplines regionally working in the field. Stigmatization of mental disorders, lack of existing training structures, and political preferences constitute significant barriers that need to be addressed to build significant capacities in this highly significant field of medicine and health care (22).

Challenge 9: Child and Adolescence Health

29.3% of the global population is younger than 18 years. This population is especially vulnerable to external stressors resulting in immediate responses or later programming of mental disorders (23, 24). Although the need to primarily protect this subpopulation is obvious, the availability of training of respective specialists and tailored interventions is widely lacking, especially in LMICs. Thus, it constitutes a global challenge to promote population-based interventions to improve mental health in this highly vulnerable and large subpopulation. Against this background, the articles of the current Research Topic “Global Mental Health in Times of Pandemic and Migration” shed light on the multiple interdependencies between mediating factors of mental health, for instance, maternal health [(25), in this issue], and these global challenges and their impact on individuals, populations, and societies across the globe. The special issue brings eleven national perspectives describing specific and general problems within mental health care systems and suggests generalizable solutions addressing the nine challenges in global mental health.
