Setting goals to help world's poorest

Setting goals to help world's poorest

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 like diarrhoea, 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 has 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 now dying from strokes and heart attacks than infectious diseases. Combined, these so-called non-communicable diseases (NCDs) cause almost two-thirds of all deaths in the developing world, about 23 million each year. In Thailand, 70% of all deaths are caused by NCDs.

The good news is that there are tremendous ways to help, which could avoid up to five million deaths each year.

This is the argument made in a new paper written by Rachel Nugent of the University of Washington. It is part of a series commissioned by my think tank, the Copenhagen Consensus Center, from more than 60 teams of top economists. The idea is to be able to compare the costs and benefits of a wide range of proposed targets to help the global community set the best targets for the next 15 years to follow the Millennium Development Goals. Later this month, the United Nations will agree to a list of targets 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.

Prof 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 17% over the next 10 years. In Thailand, deaths from NCDs have increased by 87% over the past two decades.

Tobacco, the single biggest killer will cause 10 million deaths by 2030. Just 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).

In Thailand, the World Health Organisation estimates that 22% of adult deaths are caused by tobacco. As 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 125% 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 US$3.5 billion (125 billion baht) annually, but it would save 2.5 million premature deaths every year. Every dollar spent would give benefits valued at $22.

About a billion people on the planet suffer from high blood pressure, causing nine million deaths. High blood pressure affects 34% of adults in Thailand. The cost of diagnosis and cheap hypertension medication would be $2.50 per year per capita, so helping high-risk patients would cost $500 million but avoid 770,000 premature deaths each year. Every dollar invested would do $47 of good.

One of the simplest ways to reduce high blood pressure is to lower salt intake. Gradual reduction of salt 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 30% is reckoned to avoid 815,000 premature deaths (more than double this if deaths over 70 are also counted). It would also be a great use of resources, paying back $39 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 multidrug regimen including aspirin, blood pressure lowering drugs, and cholesterol-lowering drugs can considerably prolong their lives. The cost is  substantial at $55 but will save almost a million lives.

The choice that the global community is faced with when agreeing on a set of post-2015 goals is not an easy one, but it is vital that the targets included can do the most good and provide good value for money.
