  • Good afternoon. It's my pleasure to share with you the overall messages and key findings of this new WHO global report: Preventing chronic diseases: a vital investment. Several misunderstandings about chronic diseases have contributed to their global neglect. This report dispels these misunderstandings with the strongest evidence and proposes a way forward for stopping the rising global epidemic.
  • The lives of far too many people in the world are being blighted and cut short by chronic diseases such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes. Globally, 58 million people will die in 2005. 35 million of these deaths will be as a result of chronic diseases. This means that 60% of all deaths in 2005 are due to chronic diseases. The projected 35 million death toll from chronic diseases is double the number of deaths from all infectious diseases (including HIV/AIDS, tuberculosis, and malaria), maternal and perinatal conditions, and nutritional deficiencies combined.
  • The majority of deaths worldwide for all ages are due to chronic diseases. Cardiovascular diseases (mainly heart disease and stroke) are responsible for 30% of all deaths. Cancer, chronic respiratory diseases, and diabetes are also major causes of mortality. The contribution of diabetes is underestimated because although people may live for years with diabetes, their deaths are usually recorded as being caused by heart disease or kidney failure.
  • The causes of the main chronic disease epidemics are well established and well known. The most important modifiable risk factors are: unhealthy diet and excessive energy intake; physical inactivity; tobacco use. These causes are expressed through the intermediate risk factors of raised blood pressure, raised glucose levels, abnormal blood lipids (particularly low density lipoprotein – LDL – cholesterol), and overweight (BMI ≥ 25) and obesity (BMI ≥ 30). The major modifiable risk factors, in conjunction with the non-modifiable risk factors of age and heredity, explain the majority of new events of heart disease, stroke, chronic respiratory diseases and some important cancers.
  • These maps tell us that the prevalence of overweight in adult women will significantly increase over the next 10 years. If current overweight trends continue, average levels of body mass index are projected to increase in almost all countries. By 2015, it is estimated that over 1.5 billion people will be overweight. Similarly, deaths from chronic diseases are projected to increase over the same period. Statistical projections show that 64 million people will die in 2015; 41 million (64%) of them will die from chronic diseases. This is a 17% increase in chronic disease deaths from 2005 to 2015.
  • The problem has serious impact. The burden of chronic disease: has major adverse effects on the quality of life of affected individuals; causes premature death; and creates large adverse – and underappreciated – economic effects on families, communities and societies in general. Chronic diseases undermine the macroeconomic development of many countries. This slide will show that countries will forego billions in national income over the next 10 years as a result of premature deaths caused by heart disease, stroke, and diabetes. China: $558 billion Russian Federation: $303 billion India: $237 billion
  • Without action, an estimated 388 million people will die from chronic diseases in the next 10 years. Many of these deaths will occur prematurely, affecting families, communities, and countries. The situation requires a rapid response that must above all be forward-looking. The vision for the future should focus on reducing deaths and improving lives.
  • Several misunderstandings have contributed to the neglect of chronic diseases. Notions that chronic diseases are a distant threat and are less important and serious than some infectious diseases can be dispelled by the strongest evidence.
  • 10. Reality: 80% of chronic disease deaths are in low and middle income countries.
  • 9. Reality: Low and middle income countries are at the centre of old and new public health challenges. While they continue to deal with the problems of infectious diseases, they are in many cases experiencing a rapid upsurge in chronic disease risk factors and deaths, especially in urban settings. These risk levels foretell a devastating future burden of chronic diseases in these countries.
  • 8. Reality: In all but the least developed countries of the world, the poor are much more likely than the wealthy to develop chronic diseases, and everywhere are more likely to die as a result . Moreover, chronic diseases cause substantial financial burden, and can push individuals and households into poverty.
  • Roberto Severino Campos lives in a shanty town on the outskirts of Sao Paulo in Brazil. He had a history of high blood pressure, before he was disabled by multiple strokes. Now, paralysed and unable to work, Roberto is entirely dependant on his family to survive. The whole Campos family have fallen into a downward spiral of worsening impoverishment. People who are already poor are the most likely to suffer financially from chronic diseases, which often deepen poverty and damage long-term economic prospects.
  • 7.Reality: Almost half of chronic diseases occur prematurely, in people under 70 years of age. One quarter of all chronic disease deaths occur in people under 60 years of age. In low and middle income counties, middle-aged adults are especially vulnerable to chronic diseases. People in these countries tend to develop disease at younger ages, suffer longer – often with preventable complications – and die sooner than those in high income countries.
  • Mariam John from the United Republic of Tanzania exemplifies that chronic diseases do occur in young people. Mariam is only 13 years old and she is battling bone cancer. Despite this terrible ordeal, Mariam remembers how to smile and is optimistic that she will be cured. Unfortunately, w ithout the necessary facilities and treatment her future looks very uncertain.
  • 6. Reality: Chronic diseases, including heart disease, affect women and men almost equally.
  • Shakeela Begum, now 65 years old, had a heart attack 10 years ago. She hasn't fully recovered from this ordeal and constantly lives in fear of having another heart attack. For financial reasons, Shakeela does not buy a sufficient amount of medication and therefore does not take the prescribed dose. She argues that by doing this she can save money for her grandchildren who are young and have a future. Some 3.6 million women will die from coronary heart disease in 2005. More than eight out of 10 of these deaths will occur in low and middle income countries.
  • 5. Reality: Individual responsibility can have its full effect only where individuals have equitable access to a healthy life, and are supported to make healthy choices. Childhood overweight and obesity is a rising global problem. About 22 million children aged under five years are overweight. Reports of type 2 diabetes in children and adolescents – previously unheard of – have begun to mount worldwide.
  • It is unfair to believe that people have only themselves and their lifestyle to blame, individual responsibility is important but governments and societies must provide supportive environments, where healthy choices are easy and accessible. Malri Twalib lives with his mother Fadhila in a small village at the base of Kilimanjaro in Tanzania. She would do anything for her precious son, but feeding him fresh fruit and vegetables is simply not within her budget. As a result Malri has a diet of high calorie, fatty foods. He simply eats too much for a 5 year old boy. Malri is obese. Fortunately village health workers have intervened, encouraging Malri to eat less, and play more.
  • 4. Reality: the major causes of chronic diseases are known, and if these risk factors were eliminated, at least 80% of all heart disease, stroke and type 2 diabetes would be prevented; over 40% of cancer would be prevented.
  • 3. Reality: a full range of chronic disease interventions are very cost-effective for all regions of the world, including sub-Saharan Africa. Many of these solutions are also inexpensive to implement. The ideal components of a medication to prevent complications in people with heart disease, for example, are no longer covered by patent restrictions and could be produced for little more than one dollar a month.
  • Another set of misunderstandings arises from kernels of truth. In these cases, the kernels of truth are distorted to become sweeping statements that are not true. Because they are based on the truth, such half-truths are among the most ubiquitous and persistent misunderstandings. Two principal half truths are presented: 2. Reality: Outliers inevitably exist, but they are extremely rare. The vast majority of chronic disease can be traced back to the common risk factors, and can be prevented by eliminating these risks.
  • Sridhar represents this reality as his many years of tobacco and alcohol use ultimately led to cancer. To pay for his medical bills, Sridhar borrowed money that he worried he would never be able to repay. Sadly, Sridhar died only a short time after he was interviewed. Each year, around 5 million people die as a result of tobacco use.
  • 1. Reality: Certainly, everyone has to die of something, but death does not need to be slow, painful, or premature.
  • Most chronic diseases do not result in sudden death. Rather, they are likely to cause people to become progressively ill and debilitated, especially if their illness is not managed correctly. Jonas Justo Kassa suffered from the symptoms of diabetes for many years before seeking help. After he was finally diagnosed with diabetes, the next couple of years were an immense relief as Jonas underwent medical treatment and changed his dietary and drinking habits. But Jonas didn't stick to his healthier ways for long eventually resulting in the amputation of both his legs – complications that could have been avoided. Feeling doomed and lonely, Jonas died in his home at the age of 65. Death is inevitable, but a life of protracted ill-health is not. Chronic disease prevention and control helps people to live longer and healthier lives.
  • The target for this goal is an additional 2% annual reduction in chronic diseases death rates over the next 10 years to 2015. The scientific knowledge to achieve this goal already exists. Pursuing this goal would result in 36 million chronic disease deaths averted by 2015.
  • Every death averted is a bonus, but the goal contains an additional positive feature: almost half of these averted deaths would be in men and women under 70 years of age and almost nine out of 10 of these would be in low and middle income countries. Extending these lives for the benefit of the individuals concerned, their families and communities is in itself the worthiest of goals.
  • The averted deaths would also translate into substantial labour supply gains. Achievement of the global goal would result in an accumulated economic growth of $36 billion in China, $15 billion in India and $20 billion in the Russian Federation over the next 10 years.
  • Chronic diseases can be prevented and controlled using available knowledge. The stepwise framework offers a flexible and practical public health approach to assist ministries of health in balancing diverse needs and priorities while implementing evidence-based interventions. Comprehensive and integrated action is required. Comprehensive action requires combining population-wide approaches that seek to reduce the risks throughout the entire population with strategies that target individuals at high risk. Even a small shift in the average population levels of several risk factors can lead to a large reduction in the burden of chronic disease. Integrated prevention and control strategies are most effective. Integrated approaches focus on the common risk factors: unhealthy diet, physical inactivity and tobacco use. They deal with a number of related diseases such as heart disease, stroke and diabetes, at the same time.
  • In many ways, we are the heirs of the choices that were made by previous generations: politicians, business leaders, financiers, and ordinary people. Future generations will in turn be affected by the decisions that we make today. Each of us has a choice: whether to continue with the status quo, or to take up the challenge and invest now in chronic disease prevention. Without action, an estimated 388 million people will die from chronic diseases in the next 10 years. Likewise, countries will forego billions in national income. With increased investment in chronic disease prevention, it will be possible to prevent 36 million premature deaths in the next 10 years. Averted deaths would in turn translate into substantial economic gains. The knowledge of how to prevent these diseases is available now. The way forward is clear. It’s our turn to take action!
