National child measurement programme (NCMP): trends in child BMI

Documents that provide a review of the changes in children's body mass index (BMI) over specific time intervals.



These documents present data on the trends in child body mass index from the National Child Measurement Programme (NCMP), between 2006 to 2007, and 2017 to 2018.

The documents cover trends in:

  • severe obesity
  • obesity
  • overweight
  • excess weight
  • underweight prevalence

Trends are examined within different socioeconomic and ethnic groups, to assess whether existing health inequalities are widening or narrowing.

The documents are intended for use by local authorities and other organisations. The slide sets can be used freely with acknowledgement to Public Health England (PHE).

A slide set is also available for trends in children’s BMI between 2006 to 2007 and 2016 to 2017.

Additional resources from previous years are available from the UK Government Web Archive.
