In developed countries such as the United Kingdom, most deaths are now caused by non-communicable diseases such as ischaemic heart disease. In particular, cardiovascular diseases cause more than a quarter of all deaths in the UK.
There’s growing evidence that lifestyle choices such as smoking, alcohol and obesity increase the risk of acquiring these types of diseases. Increasingly, more money is being spent on the treatment of obesity and diabetes, with around two-thirds of adults and 1 in 5 children leaving primary school living with obesity.
Successive governments have pursued health policies with an aim of curbing these costs, with the former Secretary of State for Health, Jeremy Hunt, stating that obesity and diabetes are top priorities. Through the introduction of the sugar tax in 2018 and the drive to educate children on the dangers of binge drinking, the government is seeking to change people’s behaviours and reduce the consumption of unhealthy products.
Whether a government implements a certain health policy depends on the benefits gained by preventing ill-health or deaths, against the human cost of infringing on personal freedoms. As of May 2018, the Scottish Government established a Minimum Unit Price (MUP) of 50p per unit of alcohol, and Wales introduced a similar MUP in March 2020. Research shows that these policies have reduced consumption in the heaviest drinking households, so there are calls for England to follow suit although the government has no current plans to do so.
A report published in 2021 named the UK government’s failure to do more to stop Covid spreading early in the pandemic (including decisions on lockdowns and social distancing) as one of the worst ever public health failures.
The sugar tax is one of the most high-profile recent public health solutions. Here’s what you need to know about the UK Soft Drinks Industry Levy:
Has it worked?
The sugar tax does seem to have been successful in raising awareness of the health impacts of excess sugar intake. Manufacturers have started adapting and reformulating carbonated drinks, and most soft drinks now fall below the sugar tax threshold. Between 2016, when the sugar tax plans were announced, and 2018, when the tax came into effect, over 50% of manufacturers reduced the sugar content of their drinks – the equivalent of 45 million kg of sugar every year.
A study of UK households showed that in the year after the sugar tax was introduced, purchasing of soft drinks remained the same, but the amount of sugar in those drinks fell by around 10%.
The current Prime Minister, Boris Johnson, has so far ruled out a proposed new tax on sugar and salt sold wholesale.
Data from the National Child Measurement Programme estimated in 2018/19 that 22.6% of children aged 4 to 5 in England were overweight (an increase of 0.2% from the previous year). This rises to a third of 10 to 11-year olds (consistent with the previous year’s data).
Improvements to home entertainment, combined with increased junk food consumption, are some of the primary factors.
The NHS is extremely concerned by childhood obesity, because of the concern that this is likely to cause major healthcare problems in the future. Key concerns include:
In 2017, the government published a plan for action on childhood obesity to try and significantly reduce it over the next ten years. As part of this plan, in June 2019, it was announced that five local councils will be given £100,000 a year over a three-year period to help test and redefine ideas for addressing childhood obesity and health inequalities.
The councils being trialled are Bradford, Blackburn with Darwen, Nottinghamshire, Lewisham and Birmingham. They will all try new programmes that may help shape future national policies. For example, Bradford will partner with local mosques to help South Asian children (who are at an increased risk of obesity) by giving them places and fun ways to exercise. Blackburn and Darwen will work with local restaurants to improve menus and include healthier options.
In July 2019, the government announced plans to ensure children have more opportunities to do 60 minutes of sport and physical activity every day, under the School Sport and Activity Action Plan. The Department of Education has committed £2.5m in 2019/20 for more training for PE teachers and to enable schools to open their facilities during holidays and at weekends. Also, Sport England will give £2m to create 400 new after-school clubs in disadvantaged areas to encourage children to get active.
In spite of a rising trend of childhood obesity nationally, Leeds has become the first UK city to see a drop, likely due to many different actions taken by the council as part of a child-obesity strategy made a decade ago. For example, staff who work with pre-school children and healthcare professionals were all trained to encourage healthy eating.
Also, through the charity Henry, parents have been offered an eight- week programme involving lessons on healthy food options and cooking healthy meals from scratch. There has been a push to encourage families to reduce their sugar intake and trying to get children more active through dance.
There’s been discussion around a fat tax – but this is much more controversial than the sugar tax because of its connotations of punishment, judgement and blame.
Some support the idea of a fat tax because:
However, many oppose this because:
The government announced a Better Health campaign to help people lose weight after it was discovered that nearly 8% of critically ill patients with COVID-19 on intensive care units were morbidly obese. That’s compared to 2.9% of the population that is morbidly obese.
The measures in the new obesity strategy include:
