Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how many adults were recorded as obese in (a) England, (b) London, (c) each primary care trust in London and (d) each London borough in each year since 2010.

Data are produced for each local authority and not by primary care trust.

Data on obese adults at a sub-national level are available through the Active People Survey and are published as pooled data for the period 2012-2014. The data for adults are from a sample survey (Active People Survey) therefore the numbers of obese adults in the population are not provided. The Active People Survey only began collecting data on adult height and weight in 2012, therefore local authority level data is not available before this date. The proportion of adults classified as obese for England is 24.0% and for London is 20.2%. Data for each local authority are available to download from:

Data on obese children are collected through the National Child Measurement Programme. The proportion of children measured as obese aged 4-5 years (Reception) in 2014/15 for England is 9.1% and for London 10.1%. The proportion of children measured as obese aged 10-11 (Year 6) in 2014/15 for England is 19.1% and for London 22.6%. Data for each local authority are available to download from:

95% confidence intervals should be taken into account when making direct comparisons of two different prevalence figures. Where confidence intervals overlap, it is not possible to determine the statistical significance (or otherwise) of the difference.
