Select Committee on Health Minutes of Evidence


Examination of Witnesses (Questions 485-499)

6 NOVEMBER 2003

DR ALAN MARYON DAVIS, MR JOHN GRIMSHAW, PROFESSOR CHRIS RIDDOCH, DR SUE CAMPBELL CBE AND MR TOM FRANKLIN

  Q485  Chairman: May I welcome you to this session of the Committee. Before I ask our witnesses to introduce themselves, may I particularly welcome Keith Bradley and Jon Owen Jones to their first meeting of the Committee. We are very pleased to see you both and we are sure you will be excellent members of the Committee and we look forward to working with you. May I welcome our witnesses and place on record our thanks to you for coming along today and for your written evidence which has been extremely helpful. Would you each briefly say a word or two about your own background and interests in this area, starting with Mr Franklin?

  Mr Franklin: My name is Tom Franklin and I am Director of Living Streets, formerly called the Pedestrians' Association. We have been around since 1929 campaigning for better streets and public spaces for people on foot, so we have a general interest in public space and making sure that people have the opportunity to walk if they want to.

  Dr Campbell: I am Sue Campbell. I am the Chief Executive of the Youth Sport Trust and the Youth Sport Trust has been engaged over the last nine years in trying to develop physical education and sport programmes specifically targeted at school age youngsters. I am also Chairman of UK Sport at the moment.

  Q486  Chairman: Did you not have a very important role as liaison between certain government departments?

  Dr Campbell: I still do. I am a cross-government adviser between DCMS and DfES on PE and school sport.

  Professor Riddoch: I am Chris Riddoch. I am at Middlesex University, formerly of Bristol University. I have been researching and teaching in exercise and health science for about 12 or 13 years.

  Mr Grimshaw: I am John Grimshaw. I am the Director of Sustrans which is a charity which builds walking and cycling routes. I have been building cycling routes for 30 years. I am a civil engineer.

  Dr Maryon Davis: I am Dr Alan Maryon Davis. I am the Convener of the Cardiovascular Working Group at the Faculty of Public Health. The Faculty is a professional body which is affiliated to the Royal College of Physicians. Its aims are to promote the advancement of knowledge in the field of public health and also to develop public health with a view to maintaining the highest possible standards of professional competence and practice and to act as an authoritative body for consultation in matters of education or public interest concerning public health. It works through professional standards and professional advocacy contributing to policy. My personal background is about 25 years in helping to promote healthy lifestyles.

  Q487  Mr Burns: During the course of our inquiry so far we have heard a great deal about the importance of healthy eating and exercise. I was wondering whether Professor Riddoch and Dr Davis could tell us how strong the evidence is that physical activity can help prevent obesity.

  Professor Riddoch: On the one hand it is a done deal that if you exercise you burn calories, so whatever you are trying to do to lose weight, if you are attacking that side of the energy balance equation, it has to have an effect. The question is how much you need to do in relation to your diet to have a marked effect. The second level to look at it is really all about whether you stick to doing it, which is the issue.

  Dr Maryon Davis: I would add to that by saying that there is a massive amount of evidence, increasing all the time. The Chief Medical Officer is producing a report putting out all this evidence in great depth, and we are expecting that in the New Year. Where the gaps are in the knowledge is not so much in terms of the benefits of exercise reducing obesity but in terms of how you persuade people to take up exercise. How do you actually implement that to make it happen in practice. That is where we need more research, more information.

  Q488  Mr Burns: We have been told that society in recent times has become increasingly more sedentary. Can this be quantified and if so how? Is it possible to disaggregate the particular factors which are underlying this growing trend in society?

  Professor Riddoch: From the transport statistics, looking at the trends for how much we walk, it has been quantified at 60 something miles a year less. That is quite substantial and that alone would explain the changes we have seen in overweight and obesity in the last 10 or 20 years. Just that one statistic is powerful.

  Q489  Chairman: The information we have from our evidence is that the National Travel Survey indicates that the average person now walks 189 miles per year. I was very surprised. I had done a quick calculation of how far I walked last week wearing my pedometer and it came to 30 miles and that was an average week, so in a year it would 1,560 miles. I do not class myself as super fit; nearly super fit but not quite. Is that correct? I find 189 miles a year incredibly low.

  Mr Franklin: That is certainly the figure from the National Travel Survey and I have to say that the way some of the information on walking is collected leaves a lot to be desired. Some of the statistics do need to be improved. What is clear is that we are walking less than we have probably ever done in history. For every five steps we took ten years ago, the average person is now taking four steps and that is bound to have an effect on our lifestyles. The reasons for that are firstly, local choice, that people are choosing to walk less and they have not thought about it. Their opportunities to walk have gone down as well. Local facilities are now further away. We think that above a fifteen-minute walk the choice of walking goes down dramatically. People will not walk after about 15 minutes and the schools, the hospitals, the local doctors, the local shops are moving so far away that people will then go into their cars instead.

  Q490  Mr Burns: The next question I should like to ask you has been slightly touched upon but I should like to ask you all. How good is the data on physical activity that we have at the moment? If the answer is not very, why?

  Professor Riddoch: Traditionally we ask people how much exercise they do, how much physical activity they do and people will report what they remember doing. They tend to remember the things they plan to do. If they went for a walk with the dog they will remember that. What they do not remember are all the incidental things they do like nipping up the stairs to the office on the floor above. Self-report measures have a fairly large amount of error built into them. We do now have much more advanced methods of measuring physical activity where we put little instruments on people and they give us a much more valid measure. Obviously they are more expensive than a piece of paper, a questionnaire, but if we are going to try to achieve this target of 70% of Britons active by 2020, we really do have to measure it properly.

  Q491  Mr Burns: I am sorry, could you say that target again?

  Professor Riddoch: It is 70% of the UK population to be active at health related levels by 2020.

  Q492  Mr Burns: What is the definition of active?

  Professor Riddoch: The current level is 30 minutes walking five days a week. That is the global target everyone seems to be aiming for at the moment, but we really do have to measure physical activity properly to find out whether that target is achieved or not.

  Dr Maryon Davis: An important issue is that whatever tool we devise, it has to be something which is very practical at the local level in terms of trying to get a measure, a base line for where we are at at the moment, say at borough level, and then also to have a look at the progress we are making over the years. Whatever tool it is, it has to be relatively simple, relatively cheap, relatively easy to put into practice so that we get useful measures of progress.

  Dr Campbell: In the work we are doing in schools we are beginning to gather much more quantifiable data. One very interesting piece of data around this whole area is actually the playground and playtime and how less active young people are now in terms of the use of that playground opportunity. We do quite a lot of studies now using pedometers to look at the kind of activity levels pre some kind of intervention and post some kind of intervention. There is no question now that young people are far more sedentary by nature almost and we are creating young people who are very computer literate, who are very engaged with other forms of learning and have almost forgotten how to learn physically. There is a huge job to do, right from the moment young people are born, in a sense to restimulate and re-engage this physical learning, learning through doing rather than learning through watching and thinking. That is a massive issue and it is going to take a long time to change attitudes towards the way young people learn.

  Mr Franklin: We found a lot of people have not really thought about the amount of physical exercise that they do. There are the global figures which are very useful for policy trends and so on, but in terms of an individual one of the most useful things is giving them a very simple pedometer. It only gives them a rough estimate of the sort of exercise they are doing, but for the first time they think about it. They think about their lifestyle choices and how they can make very small changes to their life and as a result of that can massively increase the amount of exercise they are doing. For individuals, the message is: keep it simple with the measurement.

  Q493  Mr Amess: I do not think there are many Committee members who, following our trip to America, have any doubt at all that this whole question is a very, very serious issue. Anything that happens in America is bound to happen over here. Although I have been studying human beings in a different way than before the trip, we are not as heavy yet as they are in America, but it is a very, very serious problem there. I want to share a couple of my prejudices with you all. This is going to lose me a ton of votes, but by and large youngsters, young people, are absolutely bone idle. The area I represent has mainly elderly people. They walk everywhere. Youngsters are so damn lazy that if their parents could drive the car into the classroom they would do that. They do not walk anywhere. Would one or two of you like to comment on the fact that we are always going to have this scheme, roll out that programme and all the rest of it? We are playing at it. It is not happening. When I left my flat this morning, all I could see was a sea of young people on these mobile phones, every one of them on a mobile phone. They were not walking, they were frozen, talking to the mobile phone. This is what is engaging young people at the moment. Can you think up any way that we can use in our recommendations at the end of this inquiry to do something serious to stop this dreadful thing which is going to cross the big pond and hit us big time?

  Dr Maryon Davis: May I just make a general point? Somehow we have to find a way of making physical activity and exercise and sport cool for young people, because there is a real problem with the image of that physical activity amongst young people. Dancing is cool; that is fine, that is acceptable. Some elite sports are cool as well. There is something about the whole business of active living which is just not cool and that is a root cause and we really have to tackle that.

  Q494  Mr Burstow: I think there is something in what David has just been saying, but I want to pick up on this point about data, which may be slightly boring, but nevertheless is very important. Dr Davis' point was about it needing to be relatively easy to collect, relatively easy to collate and possibly relatively reliable as well. There is a tradeoff between all those things. The thing I have not actually heard from any of the witnesses yet, and it would be helpful to get some fix on this, is the method. We need to be a lot more concrete about what it is we should be measuring, how we should measure it, what are the specific mechanisms we should use. Pedometers were referred to. Is that the be-all and end-all of effective measurement? Are there other things we should be looking at as ways of ensuring we do get an accurate base line from which we can then measure progress?

  Professor Riddoch: You are absolutely right that measurement is critical. What we have to remember is that physical activity is not the same as fitness. Fitness is easy to measure, it is a physiological trace, you can put somebody on a treadmill and you can apply very intricate science to get a very accurate score. Physical activity is a very complex human behaviour and we do it in a variety of different ways. If we went round the Committee now and asked how you take your exercise, we would find squash players, people who walk the dog, people who cycle to work or we might find people who do nothing. I do not know.

  Q495  Mr Burstow: Profesor Riddoch, we are asking the questions today, not answering them.

  Professor Riddoch: We do have to apply what technology we have to capture the essence of that complex behaviour and to me it is instrumentation rather than pencil and paper and questionnaires. If we could go down that route—and we have to invest in it because these things do cost money—we would get a really valid base line now, that Alan was talking about, and we would be able to monitor trends accurately over time.

  Dr Maryon Davis: That is fine, but any kind of a clinical measurement, face-to-face measurement, is time consuming and expensive and you do need the gear. What public health professionals need across the whole patch is some simple way of getting the history from people as to what their regular exercise is and we do have tools for that. We also just need something which can be done on a questionnaire basically. There are tools for that, but they are not as valid as the more physiological tools. We need to decide on a standard tool for measuring that on a population basis across thousands of people and then stick to it.

  Q496  Mr Jones: Forgive me if this point has been raised before, since I am a new member and I have not read every word of the Committee's deliberations. Spurred on by the prejudices of my colleague, I do not think mine are prejudices, but they may be. It would seem to me that one of the most important factors which influence the way in which children walk is the perception, more than perception, the parents' realisation that children are at great danger in walking, not particularly from attack from other adults, but from cars. I have three young children and it is not possible and safe to allow my children to walk anywhere until they are ten or eleven, whereas where I was brought up I walked everywhere because the danger from traffic was so much less. Is that a prejudice on my part? Is it a prejudice which can be supported by any evidence?

  Mr Franklin: Without doubt you are right. The conditions for people walking have got worse over the last half century or so, as there has been a rise in the motorcar, but also, the focus of people who are managing our streets has been about moving the traffic as fast and efficiently as possible and pedestrians have got in the way, so they have been shoved to one side. Very often the conditions for pedestrians have been getting worse and worse. That is why this has to engage with the traffic engineers, with people within the Department for Transport who have so much responsibility for the condition of our public spaces, if we are really going to make walking much easier, much safer. That is why we need a national walking strategy in this country, which is looking very seriously at what we can do to turn that tide, to make it safer. Safe Routes to Schools has been very, very successful in a very small way in turning that tide, in making it easier around schools for children to walk. You can promote walking. You can say to parents that it is safe, it is possible for the children to walk and then you can see a massive increase in the walking that is being done. I do not think children are naturally bone idle; they have learned that.

  Q497  Mr Amess: You want to come to my house. I am going to have to get a Stannah lift to get them to go upstairs to turn their bedroom lights off. It is incredible.

  Mr Franklin: For the first time ever less than half of our young children are walking to school. They have learned habits which they will take with them through the rest of their life which is that you drive round the corner rather than walk round the corner.

  Dr Campbell: Just to tackle your complete prejudice here, I do agree that young people are not as active as they used to be and that is why I talked about those early years of valuing physical activity and engaging youngsters happily in physical activity. If you watch really young children, they do naturally move, that is how they explore, how they learn, they pick things up and put them down. They are always crawling around doing things. That is what the animal in them does. Somehow, by the way we have introduced technology, perhaps the way we have emphasised intellectual ability, very highly, very strongly, what we have done is devalue the physical. So even parents, although they were taught positively about physical education in school, when actually asked to compare that with whether the youngsters are achieving academically, will say academic work is actually much more important. We have to try to re-engage this notion of the physical and that being physical healthy and physically well is a valid parenting skill as much as anything else. What we are finding, with the work we are doing in physical education in schools is something we all instinctively know, but we now have the evidence to prove it and that is that where young people are engaged in better physical education, physical activity, programmes, they are achieving better academically. It is not a detractor, it actually helps. Somehow we have to re-engage everybody in understanding that. The old mind, body and spirit thing is actually real. Somehow the mind has become so important in our society in so many ways that the body part has slowly got pushed down the agenda.

  Q498  Mr Amess: Would you agree that if the children are active, they are likely to remain active later in life?

  Dr Campbell: It is; it is a massively complex issue and there are no simple answers unfortunately. I cannot sit here and give you one simple answer. Certainly we have found that where we can keep young people active and engaged and particularly within schools they feel a sense of involvement, engagement and accomplishment. We have a lot to do still to get it right in schools, because we still tend to emphasise the best and not the rest. We really have to work hard at PE and school sport being something for everyone, not just the ones in the school teams and making sure that the kinds of menus we are offering within schools and in school playgrounds and around schools are really attractive to every youngster. I think that is very critical. Yes, all the research I have seen—and I am not as learned as these two gentlemen—would say to me and all the research we are gathering says that those young people who are engaged in physical activity and living what we would consider to be physically healthy lifestyles are achieving better academically, are often socially better integrated and certainly in terms of young women tend to have a better self body image, better self confidence and therefore tend to fall into problems less readily which we might associate with young teenagers for example. The evidence in my mind is indisputable and the strategy of how we actually bring this into everybody's life in the way we would all like to, is not simple.

  Q499  Mr Bradley: want to go back to the point Jon raised about safety and you concentrated on walking but it is equally true of cycling. You say that Safe Routes to School is working but is it really working in the sense that parents feel they can happily send their children out on their bicycles to school with safe routes? Is there a better mechanism through planning and design to ensure that safety? I have young kids. They want to cycle to school but, picking up the point about being cool, one of the deterrents is that they do not actually wearing their helmets to be safe when they are cycling to school because it is not cool. My daughter says she is called Mushroom Head. It is an important point that you need not only the routes, you need the design and you need it to be seen as something which is appropriate for children. When I was a kid everyone cycled to school. Now it is a great minority sport. If you get kids cycling, then they are more likely to carry on cycling into later life. How do we actually ensure that safety element is built in, particularly in urban areas?

  Mr Grimshaw: You are raising a whole series of issues. Charles Clarke has recently launched an extremely interesting programme for Safe Routes to Schools nationally and he is working with his counterparts in Transport. We know from Europe, Denmark for example, that very large numbers of children still cycle. They cycle because the whole culture has encouraged them to do it. One of the key parts of that culture, as far as we can see, is that there is a champion in every school. That champion may be the head teacher, it might be somebody on the board, it might be a senior teacher, but there has to be somebody who takes the lead. Without that you have this image issue. We have to tackle issues like helmets. There are two sections in the Department for Transport warring over whether or not to have helmets. You either encourage people to cycle, in which case you have to put helmets a little to one side and make it optional. If you make them compulsory, all the evidence from Australia and America is that you get very low levels of cycling. Certainly the medical people here will know that the level of risk of not cycling is greater than the level of risk you have from an accident while cycling. In other words, you are far more likely to suffer from lack of exercise. Picking up David's point about his indolent children, we have surveyed tens of thousands of children and the actual survey work is that something like 90% of all primary school children in the UK have bikes. Of the primary school children, something like 75% of them want to cycle to school, but only 2% are allowed to. If there were anything, dare I say, that members of the Committee wanted to do and 75% of you wanted to do it, that would immediately be allowed. What you are talking about actually is the child suffering in an adult's world, where an adult has created a world in which the needs of the child are not considered important. For example, most of us would consider that the child's journey to school is the equivalent of the adult's journey to work. We should consider it as important as that, but transport policy is made by men in suits and they consider their journey more important. For example, one quarter of all journeys in the UK are under one mile and 43% are under two miles. I am sure if you asked a road engineer, he would say he drives ten miles to work, but that is not the average journey. For a child, journeys are very short, yet of these journeys of under a mile, 17% are by car and 36% of journeys under two miles are by car. These are journeys which could be done by bike. These are journeys which we really need to tackle. If I dare go on, the issue is that the streets are designed for motorists. I do not think a single one of you will have a walking street where you as a pedestrian get a priority at a junction. The Highway Code say that motorists should give way to pedestrians at junctions, but no pedestrian who is alive has ever obeyed that rule. We know that motorists will not. There are design standards which simply say that we could give the pedestrian pavement run-across at every residential junction. That would be a symbol to the child in particular that they are considered important. The same with traffic speeds. If you go to a German city, speeds are down to 20 miles an hour (30 kilometres) and accident rates are way down. Hull has pioneered it in Britain and it has accident rates which are only half of the UK accident rates. There are plenty of techniques around, we just have not adopted them. The very wide programme announced by the Secretary of State for Education a few weeks ago, £50 million, is really going to tackle this on a wide scale. If I might just pick up on the last point about habit, we know from European countries that if you want high levels of cycling as adults you have to have higher levels as children. In Britain we only have cycling levels of 1% as children to school. So the Government has no hope of meeting its target of getting to 8% of all journeys by bike which is its target by 2012. To achieve that it would have to get cycling up to 15% by analogy with European schools, which probably means 30% in half the schools in the country, because some schools give up. Picking up David's point, I hope that your children were in the 75% of children who actually wanted to cycle when they were children, but maybe you did not permit them.
