title: Prevalence of severe childhood obesity in England: 2006-2013.
abstract: BACKGROUND
  International evidence shows that severe paediatric obesity results in an increased risk of ill health and may require specialised weight management strategies, yet there remains a lack of data on the extent of the problem.
  
  
  OBJECTIVE
  To examine the prevalence of severe obesity in children aged 4-5 and 10-11 years, attending English schools between 2006/2007 and 2012/2013.
  
  
  METHODS
  A retrospective analysis of National Child Measurement Programme (NCMP) data.
  
  
  METHODS
  Maintained schools in England.
  
  
  METHODS
  All children aged 4-5 and 10-11 years included in the NCMP dataset.
  
  
  METHODS
  Prevalence of severe childhood obesity, defined using the 99.6th centile of the British 1990 (UK90) growth reference for body mass index (BMI), analysed by sex, geography, ethnic group and deprivation.
  
  
  RESULTS
  The key findings show that in 2012/2013, severe obesity (BMI ≥UK90 99.6th centile) was found in 1.9% of girls and 2.3% of boys aged 4-5 years, and 2.9% of girls and 3.9% of boys aged 10-11 years. Severe obesity prevalence varies geographically and is more prevalent in children from deprived areas, and among those from black ethnic groups.
  
  
  CONCLUSIONS
  The findings from this study should help to raise awareness of the prevalence of severe obesity and support the provision of adequate treatment and prevention services both to support children who are already severely obese and reduce the prevalence of extreme weight in the future.
