Area of Science:

  • Nutrition Science
  • Public Health
  • Sociology

Background:

  • The concept of hunger has evolved into the more precise terms of food security and food insecurity.
  • Food security is defined as consistent access to sufficient, safe, and acceptable food for an active, healthy life.
  • Food insecurity arises when access to food is limited or uncertain.

Purpose of the Study:

  • To define and delineate the concepts of food security and food insecurity.
  • To identify key constructs, risk factors, and consequences associated with food insecurity.
  • To propose indicators for measuring food security/insecurity within nutritional assessments.

Main Methods:

  • Conceptual analysis and definition refinement of food security and insecurity.
  • Identification of quantitative, qualitative, psychological, and social factors in food insecurity.
  • Exploration of risk factors affecting household food acquisition and potential health consequences.

Main Results:

  • Food security requires both availability and accessibility of adequate, safe, and acceptable foods.
  • Food insecurity is characterized by limited or uncertain access, influenced by involuntary and periodic factors.
  • Risk factors impact household resources for food acquisition, with potential consequences including malnutrition and negative health outcomes.

Conclusions:

  • Further research is needed to clarify the complex relationships between food insecurity, its risk factors, and health consequences.
  • Standardized measurement of food insecurity is crucial for understanding nutritional status at individual, community, and national levels.
  • Indicators of food security and insecurity should be integrated into core nutritional assessments.
