As part of the work on implementing the project “Promoting healthy growth and preventing childhood stunting”, the World Health Organization has worked with various experts to prepare nine papers for a supplement of the Maternal and Child Nutrition Journal. The papers will contribute to ongoing reflections on multiple aspects of the challenges presented by a World Health Assembly 2012 target for stunting reduction and ways to address them.

You can download the chapters (free) from the Maternal and Child Nutrition web site. September 2013. Volume 9, Issue Supplement S2. Pages 1–149
