Other reports and statistics
Summary
This National Obesity Audit (NOA) publication presents a series of developing measures related to weight management services (WMS) in England. It aims to bring together existing comparable data from the different types of adult and children’s WMS across England in order to drive improvement for the benefit of those living with overweight and obesity.
This publication includes data on NHS funded bariatric surgery from Hospital Episode Statistics (HES) and WMS metrics from the Community Services Data Set (CSDS).
The National Obesity Audit is part of the National Clinical Audit and Patient Outcomes Programme (NCAPOP).
Disruption relating to the coronavirus illness (COVID-19) would seem to have affected the quality and coverage of some of our statistics, therefore, data should be interpreted with care over the COVID-19 period.
