08/11/2005 - National health campaigns encouraging people to be immunized against influenza and discouraging overuse of alcohol and cigarettes are less expensive than curing the diseases they cause. But OECD countries spend, on average, only 3% of their healthcare budgets on prevention and public awareness programmes.
That's one of the many statistics in the latest edition of Health at a Glance, a biennial publication from the OECD which provides a wide range of comparative statistics concerning health status, risk factors and healthcare resources and use. While governments search for ways to make their healthcare systems more efficient and cost-effective, the statistics show that life-style changes can make people healthier and reduce healthcare costs in the long run.
Public awareness programmes, in some cases combined with legislation, can have an impact on behaviour. In the Netherlands, almost 80% of older people were immunized against influenza in 2003 following media campaigns aimed at raising awareness and reducing concerns about the safety of flu and cold vaccines. In Canada, the United States and Sweden, numbers of smokers dropped by half over the past 20 years to fewer than 20% of the population.
Life-style choices contribute to heart diseases and strokes, which are the cause of death for 38% of people in OECD countries. Death rates from heart attacks, caused by fatty deposits in the coronary artery, vary widely across countries. But it is noticeable that people in the Slovak Republic, Hungary and the Czech Republic, where diets are heavy in fats, are up to ten times more likely to die of heart attacks than those in Japan and Korea where they have low-fat diets.
Health at a Glance warns that increasing obesity could counteract the positive trend of falling death rates due to heart disease and strokes over the past 40 years in most OECD countries. More than 50% of adults are now defined as either being overweight or obese in ten OECD countries: the United States, Mexico, the United Kingdom, Australia, the Slovak Republic, Greece, New Zealand, Hungary, Luxembourg and the Czech Republic. As obesity is a risk factor for hypertension, high cholesterol, diabetes, heart diseases, stroke, asthma, arthritis and some forms of cancer, the rise in obesity over the past two decades could mean higher healthcare costs in the future.
This edition of Health at a Glance also provides information about the physician workforce, including new data for about half of OECD countries on physicians' income:
