Modern Public Health Challenges

While modern medicine has made extraordinary progress, Britain continues to face significant public health challenges. Understanding these issues and the government's responses is essential for the final part of the AQA GCSE History: Health and the People specification.

Lifestyle Diseases

In the 21st century, many of the biggest health threats are caused by lifestyle choices rather than infectious diseases.

Disease	Cause	Scale
Heart disease	Poor diet, lack of exercise, smoking, alcohol	Leading cause of death in the UK
Type 2 diabetes	Obesity, poor diet, lack of exercise	Over 4 million people in the UK diagnosed
Lung cancer	Primarily smoking	Around 47,000 new cases per year in the UK
Liver disease	Excessive alcohol consumption	Deaths have increased by 400% since the 1970s
Obesity	Poor diet and sedentary lifestyles	Around 28% of adults in England are obese

Exam Tip: Lifestyle diseases are the modern equivalent of the public health crises caused by industrialisation. Just as the government had to intervene in the 19th century to improve sanitation, it now intervenes through health campaigns, taxation, and legislation to tackle smoking, obesity, and alcohol abuse.

Government Public Health Campaigns

The government has taken an increasingly active role in promoting public health through legislation and campaigns.

Smoking

Date	Action
1962	Royal College of Physicians publishes report linking smoking to lung cancer
1965	TV advertising of cigarettes banned
1971	Health warnings required on cigarette packets
2003	Tobacco Advertising and Promotion Act bans almost all cigarette advertising
2007	Smoking banned in enclosed public places and workplaces in England
2012	Ban on cigarette vending machines
2017	Standardised (plain) packaging introduced

Alcohol

Action	Detail
Minimum pricing	Scotland introduced minimum unit pricing for alcohol in 2018; Wales followed in 2020
Advertising restrictions	Alcohol advertising cannot target young people
Public health campaigns	"Drink Aware" and recommended weekly limits (14 units per week)

Obesity

Action	Detail
2018	Sugar tax (Soft Drinks Industry Levy) introduced, taxing drinks with high sugar content
2020	Government obesity strategy announced, including calorie labelling on menus and restrictions on advertising unhealthy food before 9pm
5 A Day campaign	Long-running campaign encouraging fruit and vegetable consumption
School meals	Standards improved following the Jamie Oliver campaign (2005)

Antibiotic Resistance

One of the most serious threats to modern medicine is antibiotic resistance --- the process by which bacteria evolve to become immune to antibiotics.

Issue	Detail
Overuse of antibiotics	Prescribing antibiotics for minor infections or viral infections (where they have no effect) has accelerated resistance
Failure to complete courses	Patients who stop taking antibiotics early allow resistant bacteria to survive and multiply
Agricultural use	Antibiotics used in farming contribute to resistance
"Superbugs"	Bacteria such as MRSA are resistant to multiple antibiotics and are extremely difficult to treat
Scale of the problem	The WHO has warned that antibiotic resistance could cause 10 million deaths per year worldwide by 2050

Key Term: MRSA (Methicillin-resistant Staphylococcus aureus) --- a strain of bacteria resistant to several widely used antibiotics. It is particularly dangerous in hospitals, where patients with weakened immune systems are vulnerable.

The COVID-19 Pandemic

The COVID-19 pandemic (2020 onwards) was the most significant public health crisis in Britain since the Spanish Flu of 1918--19.

Aspect	Detail
Cause	The SARS-CoV-2 virus, first identified in Wuhan, China, in December 2019
Impact	Over 200,000 deaths in the UK; lockdowns, school closures, economic disruption
Government response	National lockdowns, furlough scheme, Test and Trace, vaccination programme
Vaccination	The UK approved the Pfizer-BioNTech vaccine in December 2020, the first country in the world to do so; mass vaccination programme followed
NHS pressures	Hospitals overwhelmed; elective surgeries postponed; staff shortages and burnout

Exam Tip: COVID-19 provides excellent material for comparison questions. Compare the government's response to COVID with responses to earlier epidemics: the Black Death (1348), the Great Plague (1665), cholera (1830s--1860s). What has changed, and what has stayed the same?

Mental Health

Mental health has become an increasingly important public health issue.

Issue	Detail
Scale	1 in 4 people in the UK experience a mental health problem each year
Historical stigma	Mental illness was historically treated with imprisonment, restraint, and asylums
Modern approach	Emphasis on therapy, medication, community care, and reducing stigma
NHS provision	Mental health services are often underfunded compared to physical health services
Campaign groups	Organisations like Mind and the "Time to Change" campaign work to reduce stigma

---

Health Inequalities

Despite the NHS, significant health inequalities persist in Britain.

Factor	Impact on Health
Poverty	People in the poorest areas live up to 10 years less than those in the wealthiest areas
Geography	Northern England generally has worse health outcomes than the South
Ethnicity	Some ethnic groups face higher rates of certain diseases (e.g. Type 2 diabetes in South Asian communities)
Access to healthcare	Rural areas may have fewer GP surgeries and longer waiting times

---

Key Dates

Date	Event
1962	Report linking smoking to lung cancer
2007	Smoking ban in enclosed public places
2018	Sugar tax introduced
2020	COVID-19 pandemic reaches the UK; first national lockdown (March)
2020	UK approves first COVID-19 vaccine (December)

Extended Worked Paragraph: Level 5 Model on a Q4 "Main Factor" Question

Question: "Has government been the main factor in responding to public health challenges in the 21st century?" (16 marks + 4 SPaG)

Government intervention has been the dominant factor in 21st-century responses to public health challenges, but its effectiveness has depended on the interlocking factors of science, communication, individuals, and chance. The 2007 smoking ban in enclosed public places, introduced in England under the Health Act 2006 following similar legislation in Scotland (26 March 2006), Wales, and Northern Ireland, produced an estimated 2.4% reduction in heart attack admissions in its first year, demonstrating that legislative intervention could produce measurable health outcomes. The Soft Drinks Industry Levy (the "sugar tax"), announced by Chancellor George Osborne in March 2016 and implemented on 6 April 2018, targeted drinks containing over 5g of sugar per 100ml at 18p per litre and over 8g at 24p per litre; manufacturers reformulated rather than pay, reducing sugar in taxed drinks by an estimated 29%. Yet government agency has been contingent. The COVID-19 pandemic (2020--22) provides the paradigmatic test case: the UK's response combined individual scientific leadership (Sir Patrick Vallance as Chief Scientific Adviser, Chris Whitty as Chief Medical Officer, Sarah Gilbert leading the Oxford vaccine team), governmental capacity (the JCVI, NHS vaccination infrastructure), communication technology (Zoom, mRNA platforms from Pfizer-BioNTech and Moderna), and chance (the prior decade of coronavirus research on SARS and MERS that accelerated vaccine development). The UK authorised the Pfizer-BioNTech vaccine on 2 December 2020 --- the first country to do so --- and administered the first dose to Margaret Keenan at University Hospital Coventry on 8 December 2020. By April 2022, over 53 million UK residents had received at least one dose. Yet the UK also recorded over 200,000 COVID-19 deaths, with excess mortality concentrated among elderly, ethnic minority, and deprived populations --- demonstrating that government intervention, even when scientifically guided, cannot eliminate health inequalities rooted in long-run structural disadvantage. A sustained judgement must therefore recognise government as necessary but not sufficient: legislation and infrastructure enable population-scale responses, but the outcomes depend on science, individual leadership, and the pre-existing social determinants of health.
