Prioritizing micronutrients for the purpose of reviewing their requirements: a protocol developed by EURRECA

Abstract

Background:

The EURRECA (EURopean micronutrient RECommendations Aligned) Network of Excellence (http://www.eurreca.org) is working towards the development of aligned recommendations. A protocol was required to assign resources to those micronutrients for which recommendations are most in need of alignment.

Methods:

Three important ‘a priori’ criteria were the basis for ranking micronutrients: (A) the amount of new scientific evidence, particularly from randomized controlled trials; (B) the public health relevance of micronutrients; (C) variations in current micronutrient recommendations. A total of 28 micronutrients were included in the protocol, which was initially undertaken centrally by one person for each of the different population groups defined in EURRECA: infants, children and adolescents, adults, elderly, pregnant and lactating women, and low income and immigrant populations. The results were then reviewed and refined by EURRECA's population group experts. The rankings of the different population groups were combined to give an overall average ranking of micronutrients.

Results:

The 10 highest ranked micronutrients were vitamin D, iron, folate, vitamin B12, zinc, calcium, vitamin C, selenium, iodine and copper.

Conclusions:

Micronutrient recommendations should be regularly updated to reflect new scientific nutrition and public health evidence. The strategy of priority setting described in this paper will be a helpful procedure for policy makers and scientific advisory bodies.

Notes

  1. Please note that this applied at the beginning of 2008 when we started this study. Some countries, such as The Netherlands (http://www.gezondheidsraad.nl/en/publications/healthy-nutrition) and Belgium (https://portal.health.fgov.be/pls/portal/docs/PAGE/INTERNET_PG/HOMEPAGE_MENU/ABOUTUS1_MENU/INSTITUTIONSAPPARENTEES1_MENU/HOGEGEZONDHEIDSRAAD1_MENU/ADVIEZENENAANBEVELINGEN1_MENU/ADVIEZENENAANBEVELINGEN1_DOCS/HGR_8309_NL.PDF), published new recommendations for all micronutrients, or for a specific micronutrient, after 2005.

  2. 75% was chosen, as on an average the ANR (published together with the INL97,5 for adults and for a selection of micronutrients only) was 75% of the INL97,5.
