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

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

Applies to England



This report presents data on the trends in child body mass index (BMI) from the National Child Measurement Programme (NCMP), between 2006 to 2007 and 2019 to 2020.

The report covers trends in:

  • severe obesity
  • obesity
  • excess weight (overweight and obesity combined) prevalence

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

The HTML report can be used freely with acknowledgement to Public Health England (PHE).

School closures, in March 2020, due to the coronavirus (COVID-19) pandemic meant that in 2019 to 2020 the number of children measured was around 75% of previous years. Analysis by NHS Digital shows that national and regional level data is reliable and comparable to previous years. Further information is available in the NHS Digital 2019 to 2020 annual report.
