I have been asked to reply.
The information is not available in the exact format requested.
Data on the prevalence of obesity among children aged two to 15 between 1995 and 2006 can be found in the ‘Health Survey for England 2006 latest trends’, published 31 January 2008. The data are presented in table 4 (obesity) of the Children trend tables 2006. This publication is available in the Library.
The classification system used for measuring obesity in children does not have a definition for morbidly obese.
