Children’s height and weight is measured in reception (aged 4-5 years) and Year 6 (aged 10-11 years) as part of the National Child Measurement Programme. Prevalence of children with a Body Mass Index classified as obese (including severely obese) is given as a proportion of all children measured. In London the recent trend for both age groups indicates no significant change in indicators.
Prevalence of child obesity in reception has reduced from 10.3 per cent in 2015/16 and 10.1 per cent in 2016/17 to 10.0 per cent in 2019/20*. Year 6 prevalence has varied from 23.2 per cent in 2015/16 and 23.6 per cent in 2016/17 to 23.7 per cent in 2019/20*.
*2019/20 collection stopped in March 2020 due to COVID-19 school closures. The number of children measured was around 75 per cent of previous years. However, analysis by NHS Digital indicates that figures are directly comparable to previous years.
