The Economics of Non-Communicable Diseases




In rich countries, the biggest causes of death are strokes, heart attacks and cancer, accounting for more than two-thirds of all deaths. But for the poorer world, people often assume that infectious diseases, such as diarrhea, tuberculosis, AIDS, malaria, measles and tetanus are the biggest killers. That is no longer true. While they are still substantial threats, broader availability of medication and vaccines, along with higher living standards have caused such communicable diseases to drop dramatically to below nine million deaths each year. For the first time, more people in the developing world are dying from strokes and heart attacks than infectious diseases. Combined, the diseases that are not infectious – the so-called non-communicable diseases or NCDs – cause almost two-thirds of all deaths in the developing world, about 23 million each year. For Ethiopia, 30pc of all deaths are caused by NCDs. The good news is that there are tremendous ways to help, which can prevent up to five million deaths each year. Because the NCDs generally have received less attention, the solutions are often very effective and very cheap. This is the argument made in a paper written by Rachel Nugent (Prof.) of the University of Washington, United States. Hers is one of a series commissioned by the Copenhagen Consensus Center (CCC), from over 60 teams of top economists. The idea is to be able to compare the costs and benefits of a wide range of proposals to help the global community set the best targets. In the year 2000, the world’s governments made a historic commitment to a set of ambitious 15-year targets under the umbrella of the Millennium Development Goals (MDGs). While much has been achieved, there is still more to be done. That is why 193 national governments are now debating hundreds of proposed targets for the next 15 years. In September, the world will agree to a list of sustainable development goals to help build a better life for the world’s poorest people. Our economic analyses show the world’s leaders where they can help the most for each dollar spent. In the study, Nugent looks at a range of targets that collectively could cut almost a third of all premature deaths from NDCs by 2030. This is a pretty demanding target, because premature death rates are already quite low in the developed world, and most of the deaths below age 70 occur in poorer countries. And the problem is accelerating. The number of people affected by these diseases is set to increase by 17pc over the next ten years, and by 27pc in Africa. For Ethiopia, deaths from NCDs have increased by a quarter over the last two decades. Tobacco, the single biggest killer will cause 10 million deaths by 2030. In China, one-third of all male deaths will be caused by tobacco then (but very few female deaths, since just a few percent of Chinese women smoke). As the rich countries have shown, the most effective way to cut smoking is to dramatically increase taxes. A tax in low and middle-income countries to increase the cost of cigarettes by 125pc would still leave cigarettes cheaper than in the West. Even considering that smuggling would increase, it would likely cut consumption in half. Administration of this tax costs 3.5 billion dollars annually, but it would save 2.5 million premature deaths every year. Every dollar spent would give benefits valued at 22 dollars. About a billion people on the planet suffer from high blood pressure, causing nine million deaths. This affects 41pc of adults in Ethiopia. This is not just a disease of the rich world – it affects nearly half of African adults. The cost of diagnosis and cheap hypertension medication would be 2.5 dollars per year per capita, so helping the higher-risk patients would cost 500 million dollars but prevent 770,000 premature deaths each year. Every dollar invested would do 47 dollars of good. One of the simplest ways to reduce high blood pressure is to lower salt intake. Gradual reduction of the salt content in bread and other processed foods has been very successful in a number of countries, with very little sign of consumer resistance. Reducing salt intake by 30pc is reckoned to prevent 815,000 premature deI n rich countries, the biggest causes of death are strokes, heart attacks and cancer, accounting for more than two-thirds of all deaths.

It would also be a great use of resources, paying back 39 dollars for every dollar spent. Finally, there are about 100 million people below 70 surviving their first stroke or heart attack, or otherwise at high risk of dying from heart disease. Providing them with a multi-drug regimen including aspirin, blood pressure lowering drugs, and cholesterol-lowering drugs can considerably prolong their lives. The cost is substantial at 55 dollars but will save almost a million lives. Every dollar will provide a benefit of seven dollars.
