The Micronutrients Database of VMNIS compiles national, sub-national and first-administrative level data on vitamin and mineral nutritional status of populations in Member States. The Micronutrients Database is used to monitor micronutrient status around the globe, provide global estimates of the burden of micronutrient deficiencies, and calculate trends in micronutrient deficiency over time.
Currently the VMNIS' Micronutrients Database contains information on anaemia, vitamin A and iodine nutritional status in populations around the world. In 2009, the VMNIS underwent two evaluations. The first was an epidemiological evaluation which assessed attributes such as: simplicity, flexibility, data quality, acceptability, representativeness, and usefulness. The second evaluation by a public health informatics specialist assessed attributes such as efficiency and functionality in regards to utilization of information technology. These evaluations included an end-user survey through which feedback from Member States and their partners was solicited. Based on these evaluations, the VMNIS' Micronutrients Database was upgraded and expanded.
