1. Sources used in this report


1.1 Hospital Episode Statistics (HES)

NHS Digital

Hospital Episode Statistics (HES) processes over 125 million admitted patient, outpatient and accident and emergency records each year.

HES is a data warehouse containing details of all admissions, outpatient appointments and A&E attendances at NHS hospitals in England. This data is collected during a patient's time at hospital and is submitted to allow hospitals to be paid for the care they deliver. HES data is designed to enable secondary use, that is use for non-clinical purposes, of this administrative data.

It is a records-based system that covers all NHS trusts in England, including acute hospitals, primary care trusts and mental health trusts. HES information is stored as a large collection of separate records, one for each period of care, in a secure data warehouse.

A detailed record is collected for each 'episode' of admitted patient care delivered in England, either by NHS hospitals or delivered in the independent sector but commissioned by the NHS.

Admitted patient care data is available for every financial year from 1989-90 onwards. HES data is now collected monthly.

Hospital Episode Statistics, Admitted Patient Care Activity publications are national statistics.


1.2 Prescription Data

NHS Business Services Authority

The prescription data included in this report uses prescribing data held by NHS Prescription Services in ePACT2, an online database. It includes items prescribed in primary care and dispensed in the community. It excludes prescriptions written in hospitals that are dispensed in the community, prescriptions dispensed in hospitals, dental prescribing and private prescriptions.

Prescriptions are written on a prescription form known as FP10 and each single item on the form is counted as a prescription item. Net Ingredient Cost (NIC) is the basic cost of a drug. It does not take account of discounts, dispensing costs, fees or prescription charges income.

2.3 Family Food

Department for Environment, Food and Rural Affairs (DEFRA)

Family Food is an annual publication which provides detailed statistical information on purchased quantities, expenditure and nutrient intakes derived from both household and eating out food and drink. Data is collected for a sample of households in the United Kingdom using self-reported diaries of all purchases, including food eaten out, over a two-week period. Where possible, quantities are recorded in the diaries but otherwise estimated. Energy and nutrient intakes are calculated using standard nutrient composition data for each of some 500 types of food. Current estimates are based on data collected in the ‘Family Food Module of the Living Costs and Food Survey’.

The Family Food publication is a National Statistic.


2.4 Health at a Glance

Organisation for Economic Cooperation and Development (OECD)

2.5 Health Survey for England

NHS Digital

The Health Survey for England series was designed to monitor trends in the nation’s health, to estimate the proportion of people in England who have specified health conditions, and to estimate the prevalence of certain risk factors and combinations of risk factors associated with these conditions. The surveys provide regular information that cannot be obtained from other sources on a range of aspects concerning the public’s health and many of the factors that affect health.
Each survey in the series includes core questions and measurements (such as blood pressure, height and weight, and analysis of blood and saliva samples), as well as modules of questions on topics that vary from year to year.

The Health Survey for England has been carried out since 1993.

The Health Survey for England is a National Statistic.


2.6 National Child Measurement Programme (NCMP)

NHS Digital

Established in 2005/06, the NCMP for England records height and weight measurements of children in state-maintained schools in reception (aged 4–5 years) and year 6 (aged 10–11 years). However, 2006/07 is the first year that the data were considered an acceptable quality although obesity prevalence for year 6 children between 2006/07 and 2008/09 is felt to be an underestimate due to low participation. The programme provides robust data for the child excess weight indicators in the Public health Outcomes Framework, and is a key element of the Government’s approach to tackling child obesity.

Public Health England (PHE) has responsibility for national oversight of the programme, and on its behalf, the central collation and analysis of the NCMP data is coordinated by NHS Digital. Local Authorities have a statutory responsibility to deliver the National Child Measurement Programme.

The National Child Measurement Programme is a National Statistic.

Appendix B: Technical Notes

1. Obesity 

1.1 Adults Body Mass Index (BMI) 

Overweight and obesity among adults is measured in the Health Survey for England (HSE) using Body Mass Index (BMI).  The BMI is calculated by dividing weight in kilograms, by the square of the height in metres (kg\m\(^2\)). 

BMI = \({Weight  (kg) \over Height^2  (m^2)}\)  

Adults are classified into the following BMI groups: 

BMI range (kg/m2


Under 18.5 


18.5 to less than 25 


25 to less than 30 


30 and over 


40 and over 

Morbidly obese 



25 and over 

Overweight including obese 


1.2 National Institute for Health and Clinical Excellence (NICE) guidance

NICE guidance suggests that the measurement of waist circumference should be used for people with a BMI less than 35kg/m\(^2\) to assess health risks (as shown in the table below).  For adults with a BMI of 35kg/m\(^2\) or more, risks are assumed to be very high with any waist circumference. 1.2 National Institute for Health and Clinical Excellence (NICE) guidance 

Assessing risk from overweight and obesity 

BMI classification


Waist circumference



Very high

Normal weight (18.5 to less than 25kg/m2)

No increased risk

No increased risk

Increased risk

Overweight (25 to less than 30kg/m2)

No increased risk

Increased risk

High risk

Obesity I (30 to less than 35kg/m2)

Increased risk

High risk

Very high risk

Obesity II (35 to less than 40kg/m2)

Very high risk

Very high risk

Very high risk

Obesity III (40kg/m2 or more)

Very high risk

Very high risk

Very high risk

For men, low waist circumference is defined as less than 94cm, high as 94-102cm and very high as greater than 102cm. For women, low waist circumference is less than 80cm, high as 80-88cm and very high as greater than 88cm.

 Further information on the NICE guidelines: 


1.3 Children - UK National BMI percentile classification 

Due to differences in growth rates among boys and girls at each age, it is not possible to apply a universal formula in calculating obesity and overweight prevalence in children. Each sex and age group therefore needs its own level of classification for obesity.

The British 1990 growth reference (UK90) percentiles are therefore used which gives a BMI threshold for each age above which a child is considered overweight or obese; those children whose BMI is above the 85th percentile are classified as overweight and those children whose BMI is above the 95th percentile are classified as obese.  The percentiles are given for each sex and age.  According to this method, 15% and 5% of children in 1990 had a BMI above this level and were thus classified as overweight/obese. Increases over 15% and 5% in the proportion of children who exceed the reference 85th/95th percentiles over time indicate an upward trend in the prevalence of overweight and obesity. Unless otherwise specified figures relating to the prevalence of childhood obesity in this report are determined by this method. 


2. Hospital admissions

2.1 Measures

The report presents four measures for the number of obesity related hospital admissions:

1. Admissions directly attributable to obesity: NHS hospital finished admission episodes with a primary diagnosis of obesity (code E66).

2. Admissions where obesity was a factor: NHS hospital finished admission episodes with a primary or secondary diagnosis of obesity (code E66).

3. Obesity admissions for bariatric surgery: NHS hospital finished consultant episodes with a primary diagnosis of obesity (code E66), and a primary or secondary procedure for bariatric surgery (the full list of bariatric surgery procedure codes used is shown in section 2.2).

4. Obesity admissions for primary bariatric surgery: As per measure 3 but excluding episodes where the only bariatric surgery procedure(s) were maintenance, revisional, or removal procedures. The number of admissions is a count of the records meeting the required criteria for the measure. 

A finished admission episode (FAE) is the first period of in-patient care under one consultant within one healthcare provider.  A finished consultant episode (FCE) is a continuous period of admitted patient care under one consultant within one healthcare provider. 

Please note that admissions do not represent the number of in-patients, as a person may have more than one admission within the year. 

The primary diagnosis is the first of up to 20 diagnosis fields in the Hospital Episode Statistics (HES) dataset and provides the main reason why the patient was in hospital. The secondary diagnosis is one of up to 19 secondary diagnosis fields. A secondary diagnosis does not necessarily indicate obesity as a contributing factor for the admission, but may instead mean that it was relevant to a patient’s episode of care.

HES data are classified using the International Classification of Diseases (ICD). The tenth revision of this classification is currently in use (ICD-10). Details of ICD-10 codes used for each of the three measures are included in the excel table footnotes.  

These measures do not include outpatient data. Outpatient data is not used as the quality of diagnosis codes are not sufficient to be sure the activity carried out was related to obesity. 

Data only includes admissions for residents of England, and for persons with no fixed abode. 


2.2 Age-standardised rates 

Rates per population for hospital admissions have been directly age-standardised using the European standard populations. This involves adjusting the number of admissions to account for variations in age profiles between areas. Changes in the values of an age-standardised rate should not be affected by any changes in the distribution of an area’s population by age. 

The European Age Standardised Rate   = Sum of (a\(_i\) * e\(_i\) ) for all age groups (\(i\))  / 100,000 

Where: a\(_i\) = age specific rate per 100,000

e\(_i\) = age specific European standard population 


2.3 Coding for bariatric surgery

The term “bariatric surgery” is often used to define a group of procedures that can be performed to facilitate weight loss although these procedures can be performed for conditions other than weight loss. It includes stomach stapling, gastric bypasses, sleeve gastrectomy and gastric band maintenance. Using Hospital Episode Statistics (HES) data held at NHS Digital, the number of FCEs for bariatric surgery has been determined where the primary diagnosis was obesity (ICD-10 code E66) and the main or secondary procedure was for bariatric surgery, based on the OPCS code for the relevant time periods. This data includes removals and/or maintenance following an initial procedure, so the counting of the same patient is more likely (where removal and/or maintenance occurred during a later episode of care). 

Also presented are admissions for ‘primary bariatric surgery’. This excludes those episodes where the only bariatric surgery procedure(s) related to removals and/or maintenance. In this data, patients are likely to only be counted once, for the initial bariatric surgery procedure. 

Since 2012/13 the OPCS codes included in the bariatric surgery definition have been aligned with the methodology used for NHS Healthcare Resource Groups (HRGs). The new HRGs were created as a result of work between the National Casemix Office at NHS Digital, the British Obesity and Metabolic Surgery Society (BOMSS) and the Chapter F Digestive System Expert Working Group (EWG). Details of that change can be found in the methodological change notice below:

Latest data are based on the tenth revision of the International Classification of Diseases (ICD-10). The FCE data for bariatric surgery are based on the Office for Population, Censuses and Surveys: Classification of Intervention and Procedures, 4th Revision (OPCS4) codes. 

The table below shows the current list of OPCS codes used. 

Appendix C: Government policy, targets and outcome indicators

This appendix covers government policy, targets and outcome indicators related to obesity, physical activity or diet.  These are particularly relevant when looking at time series data elsewhere in the report. 

1. Obesity 

1.1 Childhood obesity plan 

The Government launched its new Childhood Obesity Plan in August 2016. The plan aims to significantly reduce England’s rate of childhood obesity within the next 10 years. Key measures include a sugar reduction programme, including a soft drinks industry levy, helping children to enjoy an hour of physical activity every day and a healthy rating scheme for primary schools. 


The Government published the second chapter of the Childhood Obesity plan in June 2018, setting out the ambition to halve childhood obesity and significantly reduce the gap in obesity between children from the most and least deprived areas by 2030. 


1.2 Sugar reduction: achieving the 20%

Public Health England

The Sugar Reduction: achieving the 20% report sets out guidelines for all sectors of the food industry on how to achieve a 20% sugar reduction across the top 9 categories of food that contribute most to intakes of children up to the age of 18 years.


1.3 Change4Life 

Change4Life is the Government’s social marketing programme supporting the ambition to halt the rise in childhood obesity.  Change4Life aims to inspire a social movement through which government, the NHS, local authorities, businesses, charities, schools, families and community leaders can all play a part in changing behaviour to help improve children’s diets and activity levels 

1.4 One You 

Public Health England’s One You social marketing campaign, launched in March 2016, aims to inform, energise and engage millions to make changes to improve their health by eating well, moving more, quitting smoking and drinking less. One You provides tools and on-going support to help people reappraise their health and make and sustain changes. The campaign is supported by an extensive range of commercial and public sector partners so adults will encounter One You on their high streets and local services, in pharmacies and GP surgeries. 


1.5 National Child Measurement Programme 

NHS Digital

The National Child Measurement Programme (NCMP) is a mandatory public health function of local authorities. The programme provides robust data on the weight status, including obesity and underweight prevalence, of over a million children in reception year and year 6 each year.  This is around 95 per cent of those eligible. The data enable local areas to plan services to tackle child obesity and monitor progress. In most local authorities, parents also receive feedback on their child’s weight status along with the offer of further advice and support on achieving a healthy weight for their child.


1.6 NHS Health Checks 

The NHS Health Check is a health check-up for adults in England aged 40 to 74. It's designed to spot early signs of stroke, kidney disease, heart disease, type 2 diabetes or dementia. As we get older, we have a higher risk of developing one of these conditions. An NHS Health Check helps find ways to lower this risk.


1.7 NHS Diabetes Prevention Programme 

There are currently five million people in England at high risk of developing Type 2 diabetes. If these trends persist, one in three people will be obese by 2034 and one in 10 will develop Type 2 diabetes.

There is strong international evidence which demonstrates how behavioural interventions, which support people to maintain a healthy weight and be more active, can significantly reduce the risk of developing the condition.

The Healthier You: NHS Diabetes Prevention Programme (NHS DPP) identifies those at high risk and refers them onto a behaviour change programme.

The NHS DPP is a joint commitment from NHS England, Public Health England and Diabetes UK.


2. Physical activity 


2.1 Sporting Future - A New Strategy for an Active Nation


Department for Digital, Culture, Media and Sport

Sporting Future: A New Strategy for an Active Nation was published in December 2015 and set out a new government vision for sport concentrating on five key outcomes physical wellbeing, mental wellbeing, individual development, social and community development and economic development. 

The government published its second annual progress report  on the sport strategy in 2018, which highlights important achievements such as the new Active Lives survey which will help to develop a fuller understanding of how people engage with sport and physical activity. It also sets out how Sport England is meeting its new responsibility for children’s engagement in sport and physical activity from the age of five.

Sport England’s own strategy Towards an Active Nation highlights Sport England’s new approach, including investing over £194 million into projects focused on improving children’s capability and enjoyment and tripling its current investment in tackling inactivity to around £250 million.  


2.2 Physical activity guidelines 

A report from the Chief Medical Officers in the UK on the amount and type of physical activity people should be doing to improve their health.


2.3 Children and Young People in Schools 

As announced in the 2016 budget, revenue generated from the ‘soft drinks levy’ will be used to double the PE and sports premium for primary schools from £160m a year to £320m from September 2017, and to increase the funding for breakfast clubs. Department for Education have also announced a new £415m Healthy Pupils Capital Fund for 2018/19 to be funded through the soft drinks industry levy to provide new facilities to support sports, after-school clubs and activities to promote healthy eating. Government will also continue to invest in the School Games which provides competitive sporting opportunities for children across the country. 


2.4 Everybody active, every day: framework for physical activity 

In October 2014, Public Health England published a national physical activity framework, Everybody Active, Every Day, following a nine-month co-production process with other 1,000 national and local stakeholders and with full ministerial involvement.  This framework presented an evidence-based approach to increase levels of physical activity and reduce physical inactivity in local communities based on international evidence of what works to increase population level physical activity. 


2.5 Cycling and walking investment strategy 

Active travel, such as cycling and walking, has a crucial role to play in improving public health. Walking and cycling are some of the easiest ways for people to build physical activity into their daily lives. The Government’s Infrastructure Act 2015 made a commitment to supporting cycling and walking over the long term by requiring Department for Transport to put a strategy in place which sets out the financial resources the Government will make available towards meeting the objectives.  

The Cycling and Walking Investment strategy (CWIS) was published in 2017


3. Diet 

3.1 Eatwell Guide 

The Eatwell Guide is a policy tool used to define government recommendations on eating healthily and achieving a balanced diet.



3.2 5 A Day  

Current recommendations are that everyone should eat at least 5 portions of a variety of fruit and vegetables each day, to reduce the risks of chronic illnesses such as heart disease, stroke and some cancers. The 5 A Day programme aims to increase fruit and vegetable consumption.


3.3 Government Buying Standards for food and catering services (GBS) 

Central government procurers directly or through their catering contractors are required to apply the GBS. Others are encouraged to follow it. It includes a set of minimum mandatory standards for inclusion in tender specifications and contract performance conditions. It also includes some best practice standards which are recommended but not required.


4. Monitoring and guidelines 


4.1 Public Health Outcomes Framework 

Launched in January 2012, the Public Health Outcomes Framework is comprised of a number of key indicators against which Public Health delivery partners can focus action to improve population health. The framework acts as a stimulus to encourage public health delivery partners to make significant improvements in services and share best practice more widely. The intention is that the introduction of benchmarking (through the indicator measures) will support better public health outcomes – this is consistent with evidence that the introduction of indicator measures can have an influence on achieving successful Health Outcomes - and will have a direct effect on protecting and improving the nation’s health.  
The Public Health Outcomes Framework Indicators help to provide robust data on diet, body weight and physical activity. This enables local authorities to make decisions about where to target population level interventions to address these issues. 


4.2 National Institute for Health and Care Excellence (NICE) guidance 

NICE guidance covers preventing children, young people and adults becoming overweight or obese. It outlines how the NHS, local authorities, early years’ settings, schools and workplaces can increase physical activity levels and make dietary improvements among their target populations.

Users and uses of the report 

From our engagement with customers, we know that there are many users of the Statistics on Obesity, Physical Activity and Diet report. There are also many users of these statistics who we do not know about. We are continually aiming to improve our understanding of who our users are in order to enhance our knowledge on what the uses of these data are via recent consultations and feedback forms available online.  

A consultation is planned for later in 2021 to gain feedback on how to make the report more user-friendly and accessible while also producing it in the most cost-effective way.  

Below is listed our current understanding of the known users and uses of these statistics. Also included are the methods we use to attempt to engage with the current unknown users.  

Department of Health and Social Care (DHSC) - frequently use these statistics to inform policy and planning. The Public Health Outcomes Framework was published in January 2012. The document sets out the desired outcomes for public health and how these will be measured.  The framework includes specific indicators for the proportion of physically active and inactive adults, excess weight in children (aged 4-5 years and 10-11 years old) and excess weight in adults. The data signposted to in this report will be used to monitor these indicators.

Public Health England - frequently use these data for secondary analysis for example the physical activity profiles ( and obesity website (

Media - these data are used to underpin articles in newspapers, journals, etc.

Public - all information is accessible for general public use for any particular purpose.

Academia and Researchers - a number of academic papers have cited the Statistics on obesity, physical activity and diet as a source of information in peer reviewed papers.  

NHS - A wide range of organisations use the information to monitor and target services to tackle obesity, physical activity and diet recommendations.  The aim is to provide a key source of obesity, physical activity and diet information for public health, commissioning and performance management colleagues at a national level.

Public Health Campaign Groups - data are used to inform policy and decision making and to examine trends and behaviours.

Ad-hoc requests – the statistics are used by NHS Digital to answer Parliamentary Questions (PQs), Freedom of Information (FOI) request and ad-hoc queries. Ad-hoc requests are received from health professionals; research companies; public sector organisations, and members of the public, showing the statistics are widely used and not solely within the profession.
