Adult Obesity Data Sources
Health Survey for England (HSE)
The Health Survey for England is an annual survey undertaken since 1991. The HSE is currently commissioned by the Information Centre (and before 2005 was commissioned by the Department of Health) to monitor the health of the population. This is currently the most robust data source to monitor trends in adult obesity in England.
Active People Survey (APS) excess weight data for the Public Health Outcomes Framework
Local authority level data on the prevalence of excess weight (overweight including obesity, BMI ≥25kg/m2) in adults has been added to the Public Health Outcomes Framework in the Health Improvement domain. The data have been collected in the Active People Survey from January 2012. We have also produced a set of additional indicators for adult underweight, healthy weight, overweight, and obesity.
Model-based estimates using HSE
Modelled (synthetic) estimates of lifestyle behaviours include estimates of prevalence of obesity among adults. These estimates are based on HSE, Census and other data. Estimates are available at local authority, primary care organisation (PCO) and middle super output area level (MSOA). It is important to note that these estimates are modelled and published as ‘experimental data’ and should be used and interpreted with caution.
Quality and Outcomes Framework (QOF)
The Quality and Outcomes Framework (QOF) is a voluntary annual reward and incentive programme for all GP surgeries in England. The QOF clinical register on obesity was started in 2006/7 and is based on patients aged 16 and over with a BMI greater or equal to 30. Current prevalence figures are unadjusted, subject to practice compliance and do not capture non-registered or non-attending patients.
