The Vitamin and Mineral Nutrition Information System (VMNIS), formerly known as the Micronutrient Deficiency Information System (MDIS), was established in 1991 following a request by the World Health Assembly to strengthen surveillance of micronutrient deficiencies at the global level. Part of WHO's mandate is to assess the micronutrient status of populations, monitor and evaluate the impact of strategies for the prevention and control of micronutrient malnutrition, and to track related trends over time. The Evidence and Programme Guidance Unit of the Department of Nutrition for Health and Development manages the VMNIS through WHO's network of regional and country offices, and in close collaboration with national health authorities.
The objectives of the VMNIS are to:
- Systematically retrieve and summarize data on vitamin and mineral status of populations.
- Provide Member States with up-to-date national, regional, and global assessments of the magnitude of vitamin and mineral deficiencies.
- Track progress towards the goal of eliminating major vitamin and mineral deficiencies.
- Provide tools and resources to support efforts of Member States and their partners for assessing vitamin and mineral nutritional status in populations.
