e-Library of Evidence for Nutrition Actions (eLENA)


The WHO e-Library of Evidence for Nutrition Actions (eLENA) is a product of a collaboration between different groups within WHO and many external partner institutions and individuals.


Cochrane is a leading producer of high quality systematic reviews in health care and is an essential partner in the eLENA project. Cochrane has shared a long history with WHO and has recently entered into a recognized partnership with WHO to formalize communication between the two organizations. This new relationship will make it easier to ensure that Cochrane reviews are updated or conducted in response to WHO’s priorities, and that they are relevant to low- and middle-income countries. This also facilitates the development of evidence-based guidelines on nutrition issues relevant to WHO Member States and other partners.
