Korry,

The report in question is the WHO Technical Report Series 916, you can find it at http://www.who.int/nut/publications.htm under "Obesity and nutrition transition" section.

According to the WHO Director-General (Rome press release, 23rd April 2003) that, "the Report (916) is significant because we will be using it as the critical science-based foundation for the WHO Global Strategy on Diet, Physical Activity and Health". This will be presented to the World Health Assembly in May 2004.
