GNHA Six Dimensions
Understanding dynamic population parameters provide the necessary context for critically evaluating diet-health relationships. The Demographics Dimension presents information at country and regional levels on population structure, mortality, fertility, and life expectancy by age, gender, and residency status. It also provides individual one-page single-country infographics on more than 190 countries around the world to give stakeholders a quick demographic overview for their target country.
Nutrition research is moving beyond the traditional focus on individual nutrients and more towards evaluating the synergistic effects of whole foods and dietary patterns on health at the individual as well as population level. The Dietary Intake Dimension offers detailed information for various populations on supply and consumption for common food groups and macronutrients – including fruits, vegetables, meat, dairy, cereal, bean, coffee, fat, protein, sugar, and salt. The specific eating habits and nutritional requirements of specific population groups, such as children and infants, are also included in this dimension.
There are complex and synergistic relationships among nutrients, including essential minerals, vitamins, amino acids, and fatty acids, and other food constituents. The Nutritional Status Dimension focuses on depicting the health conditions for a specific population and how it is influenced by the intake and utilization of nutrients. Data about stunting, anemia and other forms of macro- or micronutrition deficiency is augmented by the availability of various biomarkers, which combined provide a multi-dimensional measurement and assessment of disease and nutrient deficiency of different groups in the population.
Evaluating the effects of dietary factors on health outcomes, including assessment for causality and estimation of the magnitudes of etiologic effects, require dietary and nutritional data to link with appropriate health-related variables. The Health Status Dimension provides information on the presence of biological or physiological dysfunction, symptoms, and functional impairment.
The incidence and prevalence of diet-related non-communicable diseases and associated conditions are on the rise globally, which are leading to reversals in life expectancy and health gains modern society has achieved at a great social and economic cost. The Health Economics Dimension provides a variety of variables about the healthcare system and the economic accountability of diseases are compiled into indicators.
Higher requirements of environmental impacts and sustainable development in food and agriculture are forming a new global food system. The Food Sustainability Dashboard covers data about a sustainable food system from multiple perspectives, with the purpose to showcase the general overview of the food system and diet sustainability. This dimension presents country-level performances at food affordability, availability, security, quality, and environmental resilience by different indexes.
The Comparison Dashboard allows users to customize plots and charts by choosing all the GNHA indicators. Dietary Intake Data from Tufts Global Dietary Database are enlisted as the third variable in this dashboard. By comparing GNHA data and Global Dietary Intake Data, users can easily investigate detailed nutrition and health topics.
