Indeed. I strongly believe that the measures outlined in the Bill go some way to tackling that situation.
Perhaps the main health effect of obesity among children is tooth decay. It is the main source of hospital admissions for five to nine-year-olds, with some 26,000 admissions, probably in England alone, and 179,000 teeth—if not more—extracted among the age group each year. Some 25% of children in the age group have tooth decay, and 90% of those cases are estimated to be preventable. Of course, sugar is a key cause of the problem. As for older children, 46% of 15-year-olds have tooth decay, and £129 million was spent on the extraction of teeth in under-18s between 2012 and 2016.
The impact of obesity on adults is even more concerning with tooth decay and, in no particular order, type 2 diabetes mellitus, cardiovascular disease, gastro-oesophageal reflux disease, gallstones, osteoarthritis, sleep apnoea, infertility, pregnancy problems, mental health problems, liver and kidney disease, and—last but certainly not least—cancer. At least 13 types of cancer have been implicated with obesity. In fact, obesity is thought to be the biggest cause of preventable cancer after smoking. More than 18,100 cases of cancer in the UK per year are estimated to be thanks to obesity. Those types of cancer include some well-known ones such as breast,
bowel, endometrial, oesophageal and pancreatic. There is an impact on the NHS of an estimated £5.1 billion per annum, and a cost to the economy in general—£27 billion a year down to lost productivity, unemployment, early retirement and welfare benefits.
It is vital that we recognise the extent of the problem posed to the health and wellbeing of ever-rising numbers of people by the obesity crisis. How should we target this? Well, it is believed that there is a genetic susceptibility to obesity. That is not to say that all obesity is down to genetics, but it is thought that the inheritance of several genes—polygenic susceptibility—leads some to an increased drive to eat. Much has been said over the past decades about personal responsibility, education and exercise. Education and exercise do have an important place, but the reality is that they have not succeeded as the main way to target the problem.
We have an issue with more sedentary lifestyles and an obesogenic environment, whereby unhealthy, high-calorie foods are so easily available around us. Calorie intake sadly overwhelms most people’s efforts to exercise those calories off. Personal responsibility certainly drives many—perhaps those with the intellectual and financial resources to follow the path to deal with the problems they face —but it is not easy. In any case, children cannot be expected to exercise personal responsibility, because they do not have their own freedom of choice. Various measures are important in tackling the crisis, including reformulation targets by Public Health England and others, which will reduce sugar, fat, calories and so on in the foods that children eat.
Advertising is also important. Advertising restrictions have recently been expanded from television to other media such as social media and advergames, but more could be done if necessary. Labelling is important, and Brexit offers an opportunity in more flexibility in labelling our products. Promotions and discounts in supermarkets and elsewhere are critical. The issue of local authorities’ planning powers for takeaways and so on has been mentioned on a number of occasions.
