Ways to share health messages and reduce the risk of developing non-communicable diseases

‘The rise of chronic non-communicable diseases presents an enormous challenge … Non-communicable diseases deliver a two-punch blow to economies and development. They cause billions of dollars in losses of national income, and they push millions of people below the poverty line, each and every year.’

Dr Margaret Chan, Director-General, World Health Organization

Non-communicable diseases (NCDs) cannot be caught but instead develop because of both genetic (inherited through your family line) and lifestyle factors. The four main NCDs – heart disease, cancer, chronic obstructive pulmonary disease (lung diseases known as COPD) and diabetes – are the biggest cause of death worldwide. More than 36 million people die each year from NCDs (63 per cent of global deaths), including nine million who die before the age of 60. More than 90 per cent of these early deaths are in developing countries and most could be prevented.

Heart disease causes the most NCD deaths (17 million per year), followed by cancer (7.6 million), COPD (4.2 million) and diabetes (1.3 million). Together, these four diseases cause 80 per cent of all NCD deaths.

A burden on communities

For people living in poverty, NCDs can have a serious impact. People often suffer with NCDs for many years, causing families to face a large financial burden, as well as the distress of the disease itself. In many cases, the person who is ill cannot work, or can only work part-time, whilst other family members are also needed at home to care for them. The cost of medical care can also push families into debt.

Economic growth is affected because if people are ill, they do not contribute to the economy. Many governments are realising that preventing NCDs is an important way of reducing poverty.

Shared risk factors

The four main NCDs share four common risk factors which increase the chance that a person will develop heart disease, diabetes, cancer or COPD:

  • tobacco use
  • physical inactivity
  • the harmful use of alcohol and
  • poor diet.

If the major risk factors for NCDs were no longer present, it would prevent around 75 per cent of heart disease and diabetes, and 40 per cent of cancer.

Global action

In September 2011, the United Nations held the first high-level meeting on NCDs to set a new global agenda and call for action. It brought together Heads of State and Government, parliamentarians, Non-Governmental Organisations (NGOs), academics and networks working on the prevention and control of NCDs. The Secretary-General of the United Nations, Ban Ki-moon, recognised the great challenge ahead. ‘This will be a massive effort, but I am convinced we can succeed,’ he said in his speech to the opening session.

The World Health Organization (WHO) believes that the cost of significantly reducing the rates of NCDs in low-income countries would be US$1-3 per person, making this a very low-cost way of increasing life expectancy. NCD cases are expected to increase significantly over the next decade so urgent action is needed.

What can we do?

At community level, health workers, churches and other community groups can carry out health promotion and education about the main shared risk factors. They can also provide support for people who want to change their lifestyles, for example by stopping smoking or improving their diets. Individuals can play their part by becoming champions of better health and making healthy living attractive to those around them.
