National Obesity Audit

The National Obesity Audit (NOA) brings together data to drive improvement in quality of care available to those living with overweight and obesity in England.


Webinars and drop-in sessions

Tier 2 and 3 weight management services who will be using the Community Services Data Set (CSDS) are invited to attend webinars and drop-in sessions.

Book your place on a webinar or drop-in session.

The technical guidance for Tier 2 and Tier 3 and weight management services using CSDS is now available. 

Overview of the audit

Nearly two-thirds of adults in England are living with overweight or obesity.  A third of children leaving primary school are living with overweight or obesity. 

Obesity is a serious health concern that increases the risk of many other health conditions, including Type 2 Diabetes, cardiovascular disease, joint problems, mental health problems, and some cancers.

NHS England and Improvement have established the National Obesity Audit (NOA) as part of the National Clinical Audit and Patient Outcomes Programme. 

NOA will bring together comparable data from the different types of adult and children’s weight management services across England in order to drive improvement for the benefit of those living with overweight and obesity. 

Services included in the audit

The audit will make use of data already collected from hospitals, community settings and general practices (GPs). This will include data from all weight management services and interventions commissioned (funded) by local authorities and the NHS.

Hospitals and GPs do not need to do anything differently for their data to be included in the audit.

Some Tier 2 and Tier 3 weight management services may need to register and start submitting to the Community Services Data Set (CSDS).

Learn more about how community providers submit to NOA.

Objectives of the audit

The NOA seeks to answer seven important questions:

  1. What proportion of people and which population groups living with overweight and obesity are being identified and recorded?
  2. What proportion of people living with overweight and obesity have been offered appropriate NICE recommended interventions?
  3. Which people living with overweight and obesity access weight management services?
  4. What are the short and long term weight loss outcomes of weight management services?
  5. Do people living with overweight and obesity transition successfully between the different types of weight management services available and from children’s to adult services?
  6. What are the health outcomes for people living with overweight and obesity?
  7. What is the coverage and provision of weight management services?

In so doing the audit aims to:

  • increase the number of people living with overweight and obesity referred to and accessing weight management services
  • improve equity of access to and engagement with weight management services
  • improve outcomes from weight management services
  • improve the transition of care from paediatric to adult services

Services and commissioners will be able to use the NOA data to deliver equitable access to effective prevention and care programmes.

Access the NOA data

We will make results of the audit available in reports. The first report is expected to be available in 2022. Data will also be made available via the Data Access Request Service. We will update this website with details on both areas in due course.
