Dr Tim Chambers explains the damaging effects of marketing of unhealthy commodities on children’s health and what we can do to tackle the problem.
Unhealthy commodities such as junk food, alcohol, and gambling are leading causes of non-communicable diseases, mental illness, injury, and many social harms. The collective global health burden of diet– and alcohol-related diseases is estimated at five million deaths each year. But what is the role of marketing of these unhealthy commodities in driving their growing consumption?
Unhealthy commodities marketing through the eyes of a child
Children’s exposure to unhealthy commodities marketing, regardless of the product, has an adverse impact on their health. For example, junk food marketing shapes children’s dietary preferences and alcohol marketing is positively associated with earlier onset drinking and the likelihood of engaging in hazardous drinking. Children are particularly susceptible to marketing as they are unable to fully comprehend the biases inherent in ads. But with the unprecedented access and engagement with different media, how much marketing for unhealthy commodities are children actually seeing on a daily basis? (more…)
Dr John Tregoning takes us on a tour of vaccination’s greatest successes, explaining how this incredible human achievement works to keep us all safer from disease – as long as we keep vaccinating ourselves and our families.
Nature wants you dead. Not just you, but your children and unborn children and everyone you have ever met.
It wants you to cough and sneeze and poop yourself into an early grave. If it can, it wants you your blood vessels to burst and pustules to explode all over your body. Put simply, Nature is trying to kill you.
And until relatively recently, it was really good at doing this. The average life expectancy of a human in 1900 was 31 years. I should already be dead.
But then science intervened with two critical innovations, clean water and vaccines, and changed everything. Clean water has had the biggest impact, but vaccines are a close second. (more…)
Dr Katharina Hauck, a Health Economist, explains how economics can help to implement universal health coverage in the real world.
Millions of people still have no access at all to health care. Millions more are forced to choose between health care and other daily expenses such as food, clothing and even a home. Globally, over 800 million people incur catastrophic out-of-pocket spending every year, with health care costs consuming at least 10% of their household budgets.
Therefore, this year’s World Health Day focuses on universal health coverage (UHC). The World Health Organization defines UHC as “ensuring that all people can use the promotive, preventive, curative, rehabilitative and palliative health services they need, of sufficient quality to be effective, while also ensuring that the use of these services does not expose the user to financial hardship.” Many countries have declared their commitment to UHC. But after the political declarations are made, policymakers are left to grapple with a central issue: what services should be made available? (more…)
This Salt Awareness Week, Dr Queenie Chan puts the salt intake guidelines to the test and looks at the reality of curbing salt intake for better heart health.
Salt and sodium are often used interchangeably, but they’re not exactly the same thing. Sodium is a mineral that occurs naturally in foods or is added during manufacturing or both. Table salt is a combination of sodium and chloride, which was one of the most valuable modes of currency in ancient times. It has been used to preserve food for thousands of years and it is most commonly associated as a form of food seasoning. Salt also plays a role in food processing, providing texture and enhancing colour. (more…)
Dr Anne Cori and Dr Marc Baguelin explain why they need the public’s help to help make data on epidemics like Ebola and Zika more accurate.
Controlling epidemics relies on key decisions, like how many hospital beds are needed and who should be vaccinated or treated first. These decisions rely on data about people who are infected, but mistakes can be made when entering information, which can lead to incorrect decisions being made.
What is the Typo Challenge?
The Typo Challenge is a fun challenge where you are asked to type dates into an app on your computer, laptop, tablet or phone, which helps us collect information about what kind of mistakes people make when they enter dates electronically. With this information we want to create software for researchers trying to better understand how epidemics spread so when they receive data about epidemics in the future they will be able to automatically check the results for accuracy by using the software.

Rebecca Blaylock is a student on the Master of Public Health programme at Imperial and here makes the case for increased access to reproductive healthcare.
Students from Imperial’s Master of Public Health programme recently organised a screening of the award-winning film “Vessel”. Vessel chronicles the story of Dr Rebecca Gomperts – a former doctor on a Greenpeace ship – who had an innovative idea to provide women with vital reproductive health services. During her time travelling the world with Greenpeace, Gomperts witnessed the unbearable suffering caused by unsafe abortions. She saw women haemorrhage to death, die from sepsis and sustain life-long disabilities, and refused to “stand there and just let that happen”. Around 25 million unsafe abortions take place every year, accounting for between 4.7 and 13.2% of global maternal deaths.
As the human T-cell leukaemia virus is discussed on the world stage, Professor Graham Taylor addresses the misconceptions surrounding HTLV-1.
Based on the number of articles published in mainstream media, and the number of interview requests I have received in the last week, it seems that everyone wants to know about HTLV-1, the human T-cell leukaemia virus, after 30 years of turning a blind eye. Why the sudden interest in a virus that few outside my field of human retrovirology have heard of? (more…)
On World Health Day, Professor Azeem Majeed takes a look at the past, present and future of the NHS.
In 2018, the United Kingdom’s National Health Service (NHS) celebrates its 70th anniversary. With the creation of the NHS in 1948, universal health coverage was finally implemented in the United Kingdom, with the NHS replacing the previous patchy health coverage schemes that had left many people with limited access to health services. All residents of the United Kingdom were given the right to register with a general practitioner, who was responsible for both providing primary care services and organizing referrals for specialist care.

An eye-opening account by Professor Sir Tony Newman Taylor on how asbestos has gone from ‘magic mineral’ to deadly dust that can cause mesothelioma.
Public awareness of the hazards of asbestos can be dated to the period immediately following the death of Nellie Kershaw aged 33 in 1924. She had worked during the previous seven years in a textile factory spinning asbestos fibre into yarn. She died of severe fibrosis of the lungs. The pathologist, William Cooke, who found retained asbestos fibres in the lungs, called the cause of death asbestosis. Nellie Kershaw was not the first case to be reported of lung fibrosis caused by asbestos. Montague Murray in 1899 had reported the case of a 33-year-old man who had worked for 14 years in an asbestos textile factory. He had died of fibrosis of the lungs which Montague Murray, also finding asbestos in the lungs, had attributed to inhaled asbestos fibres. The patient had told Murray he was the only survivor from ten others who had worked in his workshop. (more…)
