Health: Obesity

Earl Howe Excerpts

Monday 4th April 2011 Grand Committee

[The Parliamentary Under-Secretary of State, Department of Health (Earl Howe)]

My Lords, I thank my noble friend for raising this important issue, about which he knows a very great deal. I value the insights that he was able to give us in his most informative introductory speech.

Obesity is one of our biggest public health challenges. In England, three-fifths of all adults and more than a quarter of children aged two to 10 are overweight or obese. The noble Baroness, Lady Thornton, reminded us of some other statistics in that connection.

Already, more teenagers and young adults are being diagnosed with type 2 diabetes. Experts tell us that if obesity stays at anywhere near its current high levels the health of the population will deteriorate dramatically in the years ahead. For instance, the National Heart Forum has predicted that, by 2050, the number of people getting diabetes because of their weight will nearly double and those with heart disease caused by obesity will rise by 44 per cent.

Our first thought has to be the human cost. Just as obesity cuts years from a person’s life, it also takes life from a person’s years. Statistics do not really convey the long-term effects of diabetes. They include limb amputations, long-term disability, chronic pain and heart disease, robbing people of their energy, their independence and their chances of a decent quality of life.

The other consideration is financial cost. Obesity already costs the NHS £4.2 billion. That figure is set to double by 2050. The prognosis is simple: make rapid progress or face a personal and financial catastrophe within a generation. As a country, we need to change our behaviour. The White Paper on public health sets out a new approach to improving people’s health that is locally centred, outcomes-driven and professionally led.

New local health and well-being boards will help to bring together the NHS and local government under a shared local strategy. The outcomes framework for public health will provide consistent measures to judge progress, and this includes two potential indicators covering obesity. Public Health England, a new, dedicated national public health service, will provide the resources, ideas and evidence to support local strategies. A specific obesity document will follow, setting out how the new system will work to reduce obesity levels.

However, as important as systems and structures may be, this is also about changing cultures. It is about encouraging greater personal responsibility. We have found that the state does not have all the answers, and the more the state intervenes, the more individual responsibility shrinks back. Rather than nannying people, we must nudge them, as the noble Lord, Lord Patel, reminded us, giving them the support and encouragement they need to look after their own health.

Although the noble Lord, Lord Patel, raised this subject, he expressed some doubts about its efficacy. I simply say to him that the Government cannot change people’s behaviour; what they can do is help people to change their behaviour themselves by encouraging them, rewarding them, making it easier and making it the norm. We can provide information to individuals to help them to make informed decisions about their health and we can provide encouragement, which we are already doing.

The noble Lord was doubtful whether the voluntary approach would work. I share his wish for an evidence-based evaluation of whatever we do. That is a core component of the responsibility deal and we are investing in it. However, as part of our new approach, we will consider what can be achieved through voluntary approaches before considering regulation. People’s lifestyle choices are affecting their health. The Government cannot address that challenge on their own. We believe that collective voluntary effort can deliver more progress and do so more quickly than regulation. Through the public health responsibility deal, we can tap into the unrealised potential of a wide range of resources that can promote healthier lifestyles and support people in achieving them. We have examples of working with industry, and this approach works. Change4Life is a recent example of how we have successfully worked with industry. We firmly believe that collective voluntary efforts can deliver real progress. The responsibility deal and deliverables arising from it have to deliver real improvements to public health, and we are looking at what independent monitoring or evaluation will be needed to that end.

While obesity often has complex social, psychological and cultural foundations, its basic cause is simple. My noble friend Lord McColl spoke about energy balance in its broadest sense. He is right: people become overweight because they take in more calories than is necessary and they do not burn off the excess calories that they do not need. I do not think that my noble friend was arguing against that proposition. It is a point clearly made in the NICE guidance on obesity and being overweight, and it is central to the Government’s approach. The NICE guidelines on obesity address the prevention, identification and management of obesity. They stress the importance of addressing both diet and energy out. The guidelines were based on the best available evidence that NICE had at its disposal at the time. However, my noble friend will be reassured to hear that NICE’s clinical guidelines are updated as required so that recommendations take into account important new information, and the obesity guideline is no exception to that.

My noble friend referred to the work of Professor Wilkin. The department is familiar with the EarlyBird diabetes study by Professor Wilkin. The study makes some useful points concerning the importance of early-life experiences for future health. It provides some useful messages on the importance of a child’s early years and the impact that this can have on the child’s future health and behaviour. However, this is one study which needs to be seen alongside other research with different findings on physical activity and weight.

My noble friend Lord McColl made very clear his emphasis on diet as the more important ingredient in weight loss. However, I think he would agree that any planned weight management programme should be tailored to the person’s preferences—their initial fitness, their health status in general and their lifestyle. The NICE guideline recognises that relatively high levels of activity may be required by certain individuals wishing to lose weight or maintain weight following weight loss. However, it also emphasises that, while an individual’s ability to be physically active may be hampered by their initial level of fitness or comorbidities, physical activity recommendations can be built up gradually, be focused on everyday activities, such as walking, and be accompanied by a reduction in sedentary behaviour. The guideline includes a raft of recommendations for clinical practice on dietary management.

Therefore, what is to be done? First, we need to give people the information and the opportunities so that people can choose to change their diet and lifestyle. A powerful way of doing this is through the Change4Life brand, which helps people to cut down on fatty and sugary foods and become more active. Another is working with industry to guide people towards healthier choices. The noble Lord, Lord Campbell-Savours, asked why we cannot ask restaurants and so on to place calorific content on menus. Through the responsibility deal, we now have 29 partners who are committed to posting calorific content on their menus in more than 4,000 restaurants. The noble Lord, Lord Patel, mentioned trans-fats, and my noble friend Lord Addington also referred to the fat content of food. They are both quite right. They will be pleased to hear that businesses have already committed themselves to removing artificial trans-fats from foods so that people can keep the tastes they enjoy without suffering such negative consequences. We shall continue to work with industry on other measures to help people to reduce their calorie intake, including reformulation. We will say more in the obesity document when it is published later this year.

A second issue is improving access to healthier food. In some areas, local shops simply do not stock healthier options. We are working with the Association of Convenience Stores to make fresh fruit and vegetables more available. The scheme has expanded incredibly quickly, with participating stores seeing a marked increase in the sale of fruit and vegetables. Of course, even if people have fresh produce, they still need to know what to do with it, so education is vital. There are many great local initiatives—involving the NHS, local authorities and a range of partners—which provide cookery schools and other local healthier eating initiatives.

The noble Baroness, Lady Thornton, spoke very eloquently about school food, and I agree with a lot of what she said. The Government are committed to ensuring that pupils can eat healthy, nutritious school food. We are supporting the School Food Trust in its work to help caterers to become more efficient while continuing to provide healthy meals. The schools budget will increase by £3.6 billion in cash terms by 2014-15—the end of the spending review period. Although the school lunch grant will not remain as a specific grant, it will be one of the grants that make up schools’ baseline funding from 2011-12. It will, however, no longer be ring-fenced; it will be for schools to decide how to spend the money.

We have not changed the current rules for free school meals. Therefore, some 900,000 pupils in the neediest families—those without work—continue to receive free meals. We took the difficult decision not to extend eligibility to low-income working families because the previous Government had underfunded this plan by £295 million. The money saved by not extending eligibility will be used more directly to improve the educational attainment of disadvantaged pupils, which is key to extending opportunities for poorer children. We are continuing to support three pilot projects of extended free school meals. We will look at the evidence from these of the costs and benefits of extending free school meals before making any future decisions on this front.

The noble Baroness, Lady Thornton, also mentioned advertising. As she knows, the television regulator, Ofcom, has placed scheduling restrictions on the broadcast advertising of food high in fat, salt and sugar during children’s programmes and programmes of particular appeal to children up to the age of 16. Since January 2009, these restrictions have applied to all channels. The Ofcom review in 2010 showed a 37 per cent reduction in the exposure of children to television HFSS advertising, with the highest reduction for children aged four to nine years, and a fall of 22 per cent in children—

[Lord Campbell-Savours]

Perhaps I may stop the noble Earl for a moment. In the first few moments of his speech he spelt out the scale of the crisis, yet almost all the measures that he has referred to are voluntary. They are based on an agreement with the industry or with this or that body. If that is not working—and it clearly is not, because the noble Earl himself set out the nature of the crisis—why, at an early stage, cannot we go down a more regulatory route?

[Earl Howe]

I hope that the Committee will allow me a little extra time in view of that intervention. The answer to the noble Lord, Lord Campbell-Savours, is that if voluntary measures do not work, we will indeed consider regulation. I need to make that clear. We have a ladder of intervention at our disposal. However, as I also emphasised to him earlier, we think that we can make progress faster by means of voluntary measures. The food labelling regulations, for example, are governed by EU law, and the noble Lord will know how long it takes to change EU law. If we can make progress more rapidly by voluntary measures in this country, I am sure that he would welcome that as everybody else would.

On the other side of the coin, although equally important, is physical activity—the calories we burn rather than consume. My noble friend Lord McColl made some strong statements on that aspect of the issue but, as my noble friend Lord Addington indicated, physical activity is important in the wider context of people’s health. The public messaging on this clearly has to be balanced. We are currently reviewing the Chief Medical Officer guidelines on recommended levels of physical activity and we hope to publish those in the summer. Incidentally, I am delighted that my noble friend Lord Addington has underlined the importance of diet and exercise because I still believe that the two should be emphasised.

Finally, we need to make sure that those who need it can get the specialist help to reduce and manage their weight effectively. Weight management providers will continue to play a key role in this area. I believe that through the new public health system, with the responsibility deal and Change4Life, we can truly make a difference over the next few years.
