Once thought of as a disease that only affected older adults, diabetes is now being diagnosed increasingly in people under the age of 30 鈥� the implications of which have yet to be fully studied.

鈥淚t is a global phenomenon occurring not just in Canada, but also in places like Hong Kong and India,鈥� said Dr. Calvin Ke, an endocrinologist and a clinical epidemiology PhD student at the University of Toronto's Institute of Health Policy Management and Evaluation (IHPME).

Ke is in the process of completing a three-part international PhD project looking at the rising rates of diabetes in South and East Asian populations in Toronto, as well as in India and Hong Kong. It is a unique approach that combines data from international partners to develop new insights into the management of the disease.

鈥淜e鈥檚 PhD research is a wonderful blend of clinical epidemiology and global health," said Dr. Rob Fowler, program director of the clinical epidemiology program at IHPME. "I suspect his findings will tease out and tremendously advance our understanding of influential factors on patient and population outcomes with respect to this disease.鈥�

The first part of Ke鈥檚 project took him to India, where he worked with renowned 麻豆直播app epidemiologist Dr. Prabhat Jha to determine how diabetes increases the risk of mortality from heart disease and stroke. While in Hong Kong, Ke has been researching the rising rates of hospitalizations among young people with diabetes, under the guidance of Dr. Juliana Chan, a leading diabetes researcher in China.

鈥淒iabetes is a global epidemic that cannot be fully addressed by one country alone,鈥� said Chan. 鈥淥ver the last two decades, we have been building a collaborative, international diabetes management and research platform that includes over 80,000 patients spanning 13 countries across Asia. These efforts are an essential first step to managing the global diabetes epidemic, and they necessitate the co-ordinated involvement of many international researchers.鈥�

鈥淭his is a big change from previous decades,鈥� Ke added. 鈥淲e are learning more and more about what happens to people when they get Type 2 diabetes at such a young age, and we urgently need to develop better solutions for young people facing this growing epidemic on a global scale.鈥�

A combination of factors, from genetic predisposition to rapid economic development and food abundance, are thought to be contributing to the rates of earlier diagnoses. Add in a sedentary lifestyle, and you have the perfect recipe for the development of this chronic condition.

Data that Ke is studying has also shown that young people with diabetes are being diagnosed with and hospitalized for further complications of the disease, such as kidney disease and heart attacks. Each hospitalization costs the health system and the economy in terms of lost wages and productivity, but there is also an indirect cost placed on the families and caregivers of patients.

鈥淥ne of our main goals is to reduce the rates of hospitalization, and help those diagnosed better manage their condition over the course of their life, by improving their knowledge of the disease,鈥� said Ke.

Better recognition from health-care providers about the level of risk associated with Type 2 diabetes at a younger age is also needed.

鈥淲hile many assume that youth confers good health, we need to understand that this is not true when it comes to young people with diabetes. In fact, we found that the overall risk of suffering complications is actually higher for young people, because they are exposed to diabetes for a much longer period of time,鈥� said Ke.

An international experience like this has added an interesting perspective to Ke鈥檚 research, and has allowed him to integrate data from three different countries in a meaningful way. 鈥淪tudying how diabetes affects people in different global contexts reveals unique aspects of this complex disease. Each study adds an important piece to the puzzle, and lessons learned in one country can be incredibly valuable to informing interventions in other settings,鈥� he said.

As it becomes more important to have an international research network, Ke encourages other students to think about the global aspects of the projects they are working on.

鈥淚 didn鈥檛 know coming into my graduate studies that my work would look like this, but to see it come together and to reflect on it, it鈥檚 quite amazing.鈥�

Research finds taxing cigarettes could keep people out of poverty and save lives

Higher cigarette prices would save millions of people from extreme poverty and poor health around the world, while also cutting health treatment costs for families across the globe, suggests a new study.

The analysis, led by 麻豆直播app Professor Prabhat Jha and the World Bank's Patricio V. Marquez, concludes that people with lower incomes would benefit the most from higher cigarette prices. Examining 500 million male smokers in 13 countries, they found that a 50 per cent increase in the tobacco excise tax would result in 67 million men quitting smoking, with the largest share being low-income men. It would also reduce years of life lost and decrease the risk of high medical costs.

The study was published this week in The BMJ. It adds to a growing body of knowledge that tobacco taxes, which are not implemented globally, have significant health benefits.

鈥淥ur study debunks the current narrative that higher cigarette prices would negatively impact the poorest among us,鈥� said Dr. Jha (pictured at left), a professor of epidemiology at 麻豆直播app's Dalla Lana School of Public Health.

鈥淭his analysis shows the opposite 鈥� a higher price would encourage cessation, lead to better health and save money, much more strongly for the poor than the rich.鈥�

Small steps taken by governments can lead to unprecedented health gains and poverty reduction, he added.

The higher price would lead to 15.5 million men avoiding catastrophic health spending in the seven countries studied without universal health coverage, according to the study. This would result in 8.8 million men avoiding extreme poverty, half of whom are in the bottom income group.

Quitting smoking would result in 449 million years of life gained, the study showed. Higher tobacco costs would also benefit households globally, with about US$157-billion averted to treat the four main tobacco-attributable diseases examined: chronic obstructive pulmonary disease, stroke, heart disease and cancer.

Despite more awareness of the risks, Jha said, if nothing changes, smoking will be responsible for one billion deaths in the 21st century. Most of these will be in low- and middle-income countries. Previous research by Jha, who is also director of the Centre for Global Health Research of St. Michael鈥檚 Hospital, has shown that raising taxes on tobacco is the single most effective intervention to lower smoking rates and to deter future smokers.

Building on his earlier research, Jha and the team undertook this new analysis to understand the true impact of higher cigarette prices around the world. They conducted an assessment across 13 middle-income countries with diverse socioeconomic characteristics, tobacco use and health-care coverage. Focusing on male smokers 鈥� who make up 90 per cent of smokers in the selected countries 鈥� the researchers used mathematical models to quantify the effect of a 50 per cent increase in prices.

鈥淭he findings of our new analysis will have a far-reaching impact,鈥� said Marquez, the lead health specialist at the World Bank. 鈥淣ot only does increasing tobacco taxation reduce smoking and its health consequences, but the study鈥檚 findings are also relevant to the United Nations sustainable development goals to reduce poverty and improve health.鈥�

The study was supported by the Fogarty International Center of the U.S. National Institutes of Health, the Dalla Lana School of Public Health, Canadian Institute of Health Research, the Bill & Melinda Gates Foundation, Bloomberg Philanthropies, and the International Development Research Centre.

Almost a decade after making a $20-million gift to establish the Dalla Lana School of Public Health at the University of Toronto, Paul and Alessandra Dalla Lana are doubling down on their investment.

Today, the couple announced they are making an additional $20-million gift to the school, located in the heart of Toronto鈥檚 innovation and health district.

鈥淚t鈥檚 been amazing to watch the school grow and to see the impact its research is already having on critically important but often overlooked public health and health system issues across Canada and globally,鈥� said Paul Dalla Lana, founder of NorthWest Healthcare Properties REIT, the largest private owner and manager of medical buildings in Canada.

鈥淭his funding will enable the school to expand this work to improve the quality of life for us all.鈥�

In the years since the couple鈥檚 original donation 鈥� the largest gift ever given to public health in Canada 鈥� the school has grown into a global leader in public health, health policy and health systems education, research and service, known for research like Professor Prabhat Jha鈥檚 innovative Million Death Study. Jha is the Endowed Chair in Disease Control at DLSPH, funded by the Dalla Lanas' original gift.

Naylor Report

Research & Innovation

After working as a senior scientist at the World Health Organization on efforts to control malaria, HIV/AIDS and tobacco-related diseases, Dr. Prabhat Jha was contemplating a return to academia 鈥搕he University of Cambridge, perhaps, or Harvard University.

For guidance, he turned to his former supervisor David Naylor, then the dean of University of Toronto鈥檚 Faculty of Medicine. Naylor told him that if he came back to Toronto, he could focus on his research.

What Jha wanted was to explore how to improve the way the world collects death statistics or mortality data, because more accurate numbers could help shape global health policy on fighting curable diseases like malaria.

麻豆直播app and St. Michael鈥檚 Hospital helped Jha, who did his PhD at the University of Oxford under a Rhodes Scholarship, find the funding needed to set up the Centre for Global Health Research and establish the Million Death Study in India.

鈥淲ithout funding, we would not have been able to start the Million Death Study,鈥� says Jha. 鈥淚n my own case, a Canada Research Chair and early support from Canadian Institute for Health Research, along with 麻豆直播app and St. Michael's Hospital, were crucial to start my centre and establish the Million Death Study in India.鈥�

The study, which began in 2002, involves hundreds of specially trained non-medical staff knocking on doors across India to gather first-hand accounts of the symptoms and circumstances behind recent deaths. The results of those 鈥渧erbal autopsies鈥� are then sent to two of 400 physicians working online to establish a probable cause of death.

It is considered one of the largest studies of premature deaths in the world and in a country like India, where many deaths occur at home and go unrecorded, has become an important tool to improve public health. The mortality study, which has now reached 3.5 million homes and more than 23 million people, costs less than a dollar per household per year in India, but the impact has been tremendous. Data have revealed that global estimates for adult malaria and snake bite deaths were too low, leading WHO to put the latter on its list of neglected tropical diseases. The organization is also re-examining global malaria numbers.

Mortality data also showed that one million more children are alive today because of simple, affordable prenatal care and reductions in specific diseases since 2005. The tobacco-related findings have enabled a global treaty signed by over 180 countries to help reduce deaths worldwide.

鈥淲e are well on the way to changing how the world counts its dead and describes causes, and in so doing are providing a GPS for global health,鈥� says Jha, a professor of global health and epidemiology at the Dalla Lana School of Public Health.

鈥淭his has now spurred others to take an interest in similar studies. We鈥檙e working with the Gates Foundation and the Canadian government to introduce systems like this in Mozambique, Sierra Leone and Ethiopia.鈥�

But Jha says that the research and the results would not have been possible without money and leadership, two things recommended by the Naylor report. The 35 recommendations made by Canada鈥檚 Fundamental Science review, which was led by Naylor, 麻豆直播app's President Emeritus, called for sweeping changes on how research is overseen and a $1.3-billion increase in federal research funding over the next four years.

鈥淭he Canada Research Chair has been a successful model to attract researchers back to Canada, and I鈥檓 one of them,鈥� he says.

The funding has helped him to focus solely on research, unlike scientists in other parts of the world.

鈥淲ithout core support for my salary, I would鈥檝e been in a bind which many U.S. researchers find themselves 鈥� where they鈥檙e actually trying to raise money to cover their salary rather than focusing on research and building research programs,鈥� he says.

Jha鈥檚 Centre for Global Health Research also conducts risk factor epidemiology globally 鈥� not just in India 鈥� on tobacco hazards, alcohol, vegetarianism, exposure to particulate matter and other risk factors.

Research is the key reason for the 20-year gain in global life expectancy over the last few decades, he says.

鈥淲hy is that? When you look carefully, as we have done, that鈥檚 not because the world grew richer or we became more educated. It鈥檚 because of research,鈥� Jha says. 鈥淩esearch led to huge fundamental discoveries that have transformed human health 鈥� vaccines that became available, the discovery of smoking as a big risk factor for cancer and other diseases, low-cost antibiotics 鈥� almost all of that knowledge has been driven by publicly funded research.鈥�

And much of the funding for that research has been through sustained public dollars, he says.

鈥淪ince about 1980, we鈥檝e somehow been thinking that the private sector will come in, and it鈥檒l fund research. Well, it鈥檚 just not really true. Fundamental achievements in public health 鈥� if you take anything, any big success 鈥� and trace its roots back, it all comes back to government funding for research that is slow and deliberate and usually goes through universities.鈥�

Jha, who was born in India and grew up in Winnipeg, received his medical degree from the University of Manitoba. At Oxford, he worked under the renowned epidemiologist Sir Richard Peto and developed a passion for digging into how seemingly preventable factors like tobacco contribute to diseases in developing countries.

He came to 麻豆直播app for his post-doctoral research, working under Naylor, and then went on to the World Bank and then the WHO, where he studied the health of the global poor. It was while he was at the WHO that he says it became obvious to him that better mortality data would help inform how to best control the major diseases and also the degree to which smoking kills people.

Colleagues say Jha鈥檚 epidemiological approach has changed global health policy.

"Not only has his Million Death Study contributed to our understanding of premature death in India, China and beyond, he is also instrumental in training maternal and child health researchers across the globe who will continue to have a far-reaching impact in decades to come," says Erica Di Ruggiero, an assistant professor and director of the Dalla Lana School of Public Health's office of global public health education and training.

Jha鈥檚 next steps with the Million Death Study will include leading an interdisciplinary team to expand the collection of mortality statistics and develop innovative new tools to analyze the data for patterns.

鈥淧rabhat鈥檚 research in tobacco control and premature mortality has influenced health policy globally and is saving lives,鈥� says Adalsteinn Brown, interim dean of the Dalla Lana School of Public Health and the Dalla Lana Chair in Public Health Policy. 鈥淏y using innovative approaches to population health data, he demonstrates the need for evidence-based change 鈥� such as tobacco tax increases 鈥� to national and institutional leaders, ultimately helping global populations live longer, healthier lives.鈥�

He says for Canadian researchers like him, the Naylor report has been a reminder of how Canada can excel and what its potential could be for the future.

鈥淸Naylor] reminded us that if there is a single way Canada can punch above its weight globally it could be to become the research powerhouse,鈥� says Jha. 鈥淭he report is spot on to recognize the enormous social and economic returns possible if Canada significantly upped its game in research funding and leadership.鈥�
