Conflict-affected settings are characterized by chronic instability, economic hardship, and social disruption, all of which profoundly impact mental and behavioral health. In such contexts, individuals are often exposed to cumulative stressors that increase vulnerability to psychological distress, maladaptive coping strategies, and health-risk behaviors. Understanding the mechanisms that shape mental health outcomes in these environments is essential for developing effective public health interventions.

This Collection aims to advance knowledge on the psychological and behavioral determinants of mental health in conflict-affected populations, with a particular emphasis on personality traits, coping strategies, resilience, and social influences. These factors play a critical role in shaping how individuals perceive, respond to, and adapt to adversity. Personality traits may influence vulnerability or protection against mental health disorders, while coping mechanisms and resilience determine the capacity to manage stress and maintain psychological well-being. In parallel, social influences such as stigma, social norms, and perceived acceptability of behaviors contribute significantly to health-related decision-making and risk behaviors.

We welcome original research articles, systematic reviews, and methodological studies that explore mental and behavioral health outcomes in populations exposed to conflict, political instability, or socioeconomic crises. Studies employing observational, analytical, or longitudinal designs are particularly encouraged, as well as those introducing innovative approaches to measurement and analysis in public health.

By bringing together interdisciplinary research, this Collection seeks to provide a comprehensive understanding of the psychological and social processes underlying mental health in fragile settings. Ultimately, it aims to inform evidence-based interventions, support policy development, and strengthen mental health systems in regions affected by conflict and crisis.

This Collection supports and amplifies research related to SDG 3: Good health and Well-Being.

The interconnection between healthy diets and food security is a critical concern for global public health systems, particularly in the context of escalating population growth, climate change, and socioeconomic disparities. Proper nutrition is essential for overall health and well-being; however, millions worldwide face malnutrition in its various forms, including undernutrition, micronutrient deficiencies, and obesity. Food security encompasses not only the availability of food but also its accessibility, utilization, and stability. Addressing these complex challenges is vital for achieving sustainable development goals and improving health outcomes across diverse populations.

This Collection is motivated by the urgent need to strengthen the integration of health policy with healthy diet promotion and food security within public health frameworks. As nations work to build resilient health systems, innovative strategies that promote healthy eating and ensure food security are essential. This Collection aims to gather interdisciplinary insights and research that address these pressing issues, fostering collaboration among public health experts, nutritionists, policymakers, and community stakeholders.

The purpose of this Collection is to provide a platform for sharing research findings and practical solutions that enhance healthy diets and food security through effective health policies. We welcome contributions that explore policy interventions, community-based initiatives, and innovative programs focused on promoting nutrition education and improving food access. By highlighting diverse perspectives and successful models, this Collection seeks to inform future public health strategies and contribute to the development of effective, equitable food systems worldwide.

Topics of interest include, but are not limited to:

- Evidence-based community interventions to enhance food security

- The influence of health policy on food systems and public health outcomes

- Global case studies demonstrating effective food access and health promotion

This Collection supports and amplifies research related to SDG 2 and SDG 3.
