The global burden of asthma: executive summary of the GINA Dissemination Committee Report

It is estimated that as many as 300 million people of all ages, and all ethnic backgrounds, suffer from asthma and the burden of this disease to governments, health care systems, families, and patients is increasing worldwide. In 1989 the Global Initiative for Asthma (GINA) program was initiated in an effort to raise awareness among public health and government officials, health care workers, and the general public that asthma was on the increase. The GINA program recommends a management program based on the best available scientific evidence to provide effective medical care for asthma tailored to local health care systems and resources. Working in continued collaboration with leaders in asthma care from many countries, GINA sponsors World Asthma Day (first Tuesday in May) which has been extremely successful. A vast number of people have made a commitment to bring awareness about the burden of asthma to their local health care officials, and to implement programs of effective asthma care. Beginning in 2003, the theme of World Asthma Day has been the ‘‘Global Burden of Asthma. ’’ GINA commissioned Professor Richard Beasley, Wellington, New Zealand (member, GINA Dissemination Committee) to provide available data on the burden of asthma. A summary of this report is provided in this publication; the full document with data sets for 20 different regions worldwide may be obtained from the GINA website (http://www.ginasthma.com). Professor Beasley and his colleagues obtained data on the burden of asthma from literature primarily published through the International StudyofAsthmaandAllergies in Childhood (ISAAC) and the European Community Respiratory Health Survey (ECHRS). Methodologies differ in these studies, and epidemiological data on asthma are very difficult to collect, as Professor Beasley carefully describes in his segment on ‘‘Methodological Issues. ’’ Nonetheless, the full report provides a wealth of information, along with a large number of scientific references. The study regions have been grouped according to geographical, political, historical, and racial considerations based on official data from WHO, the United Nations (UN), and other sources, and to some extent, the availability of asthma epidemiological data within the study region. Using the United Nations World Population Prospect Population Database (http://esa.un.org/unpp) as a source within each region, all countries were included, and in some cases territories and dependencies if specific asthma epidemiological data were available. For simplicity some data from small territories have been omitted or lumped in a larger sub-regional unit. The report will be updated as new information becomes available and following feedback from individual countries and regions. The GINA Executive Committee is indebted to Professor Beasley and his colleagues for providing this report that will be an invaluable source of information for those who wish to explore available data on the burden of asthma by region. It will be extremely useful to develop background materials for World Asthma Day activities in 2004 and well into the future.
