Key research themes

1. How does food insecurity impact children's health, cognitive development, and psychosocial well-being?

This research area investigates the immediate and long-term effects of food insecurity and hunger on children's physical health, cognitive development, and behavioral outcomes. Understanding these impacts is critical to inform interventions that promote child development and mental health in food-insecure populations.

Key finding: Using longitudinal Canadian data, this paper demonstrates that food insecurity and hunger among children are associated with poor health outcomes such as increased risk of depression, suicidal ideation, chronic conditions... Read more
Key finding: This study identifies a significant association between children's experience of food insecurity and the shame felt when others know about their lack of food (γ = 0.37, P < .01). It further elucidates how nine out of eleven... Read more
Key finding: This national-level analysis employing the Community Childhood Hunger Identification Project index finds that 32.5% of South African households with children experience hunger, with food insecurity disproportionately... Read more

2. What is the prevalence, determinants, and consequences of food insecurity among university students in developing and transitioning countries?

This theme centers on the high and worsening rates of food insecurity within university student populations, especially in regions with broader household food insecurity challenges. It examines socio-demographic predictors, coping strategies, and the implications for academic success and psychological well-being, emphasizing the need for targeted institutional and policy-level interventions in higher education.

Key finding: Employing a large cross-sectional web-based survey of 1,416 students, this study reports extremely high food insecurity prevalence (65% by a one-item measure; 60% with hunger using the USDA 10-item scale). It identifies key... Read more
Key finding: Corroborating findings from the previous study with identical sample and methodology, this article further clarifies that food insecurity in students is a hidden but pervasive problem in South Africa, despite national food... Read more

Key finding: In a Turkish university sample of 1,149 students, the study finds food insecurity associated with decreased frequency of consumption of fruits, vegetables, dairy, fish, meat, and legumes. Food insecure students exhibit poorer... Read more

3. How do socioeconomic, geographic, and systemic factors contribute to the prevalence and experience of food insecurity in rural and vulnerable populations globally?

This theme addresses the spatial, economic, and structural determinants of food insecurity, emphasizing rural and marginalized communities. It includes the examination of poverty, unemployment, infrastructure challenges, agricultural dependency, systemic shocks (e.g., climate change, economic crisis), and governance issues contributing to persistent food insecurity. This informs policy and humanitarian strategies to address root causes beyond immediate food provision.

Key finding: This paper contextualizes food insecurity within spatial inequality frameworks, detailing how rural America faces higher poverty (17.7% vs 14.5% metropolitan), slower economic recovery post-2008 recession, limited employment... Read more
Key finding: Through comprehensive review, the study reveals that social dimensions of food insecurity—such as stigma, social exclusion, and access barriers—are under-reported and inadequately captured in current food insecurity and... Read more
