Health
Background
Good health brings many benefits, including enhanced access to education and the job market, an increase in productivity and wealth, reduced health care costs, good social relations, and of course, a longer life.
Life Expectancy
Life expectancy is the most widely used measure of health, although it only takes into account the length of people’s life and not their quality of life. There have been remarkable gains in life expectancy over the past fifty years in OECD countries. On average, life expectancy at birth reached more than 79 years in 2008, a gain of more than 10 years since 1960. The OECD country with the highest life expectancy is Japan, with a life expectancy for women and men combined of 82.7 years. At the other end of the scale, life expectancy is the lowest in Turkey (73.6 years), followed by Hungary (73.8 years).
Recent OECD analysis suggests that health care spending growth accounts for much of the improvement in life expectancy over the past 15 years, but other determinants such as GDP growth, rising living standards, environmental improvements, lifestyle changes and education are also important drivers. Taken together, these explain much of the cross-country differences in health status, as well as their changes over time. Further progress in population health status and life expectancy can be achieved by putting greater emphasis on public health and disease prevention, and improving the quality and performance of health care systems.
Chronic (non-communicable) diseases, including cancer, cardiovascular diseases, chronic respiratory conditions and diabetes, are now the main causes of disability and death in OECD countries. In 2008, chronic diseases caused around three-quarters of all deaths in OECD countries. Many chronic diseases are preventable as they are strongly linked to modifiable lifestyles. People who do not smoke, drink alcohol in moderate quantities, are physically active, eat plenty of fruits and vegetables, and have a normal weight have a much lower risk of early death than those who have unhealthy habits.
A number of OECD countries have achieved remarkable progress in reducing tobacco consumption over the past few decades, although it is still a leading cause of early death and the largest avoidable risk to health. Much of the decline in tobacco consumption can be attributed to public awareness campaigns, advertising bans and increased taxation. Less than 20% of adults in Sweden, the United States, Australia, Canada, and Iceland now smoke daily, down from over 30% in 1980. However, tobacco consumption remains high in certain countries such as Greece where almost 40% of adults continue to smoke on a daily basis.
Overweight and obesity is another important risk factor for many chronic diseases and a growing public health concern. In almost half of OECD countries, 50% or more of the population is now defined as being at least overweight if not obese. The prevalence of obesity varies from less than 4% in Japan and Korea to 30% or over in Mexico and the United States. The rate of obesity has more than doubled over the past 20 years in many OECD countries. In the past few years, governments in many OECD countries have begun to introduce different policies to combat obesity through promoting more balanced diets and physical activity. Many governments have adopted initiatives aimed at school-age children, changing the school environment and school menus, as well as including health and lifestyle education in the school curriculum.
Self-Reported Health
Most OECD countries conduct regular health surveys which allow respondents to report on different aspects of their health. The commonly-asked question, "How is your health?", is one way to collect data on self-perceived health status. Despite the subjective nature of this question, the answers received have been found to be a good predictor of people’s future health care use. Across the OECD, 69% of the adult population rate their health to be ‘good’ or ‘very good’. In New Zealand, Canada and the United States 90% of people report to be in good health; at the lower end of the scale, less than 50% of those in Japan, the Slovak Republic, Portugal, Hungary and Korea rate their health to be ‘good’ or ‘very good’.
