Chronic respiratory diseases: burden, population and interventions, focus on LMIC (Dr. Eugene Zheleznyakov, Technical Officer, Chronic Disease Prevention and Management, WHO, Geneva)
Did you know?? 4 000 000PEOPLE DIED FROMCHRONIC RESPIRATORY DISEASES IN 2005
Chronic respiratory diseases worldwide Main NCDs include: • Cardiovascular diseases mainly heart disease and stroke • Cancer • Chronic respiratory diseases • Diabetes
Projected disease deaths and burden. 2005 Preventing Chronic Diseases, a vital investment, WHO, 2005 Main causes of global burden of disease (DALYs) Main causes of death Communicable diseases Maternal/perinatal Nutrional deficiencies 7% Cardiovascular Cancer 4% CRD Diabetes Other chronic diseases Injuries
Chronic respiratory diseases worldwide Hundreds of millions of people have chronic respiratory diseases • including 300 million people with • asthma • 210 million people with chronic obstructive pulmonary disease (COPD) • Millions of people with allergic rhinitis, sleep apnoea syndrome and other chronic respiratory diseases

The aim of the WHO chronic respiratory diseases programme as a part of NCD programme is to support member states in their efforts to reduce the toll of morbidity, disability and premature mortality related to chronic respiratory diseases, and specifically, asthma and chronic obstructive pulmonary disease (COPD). Objectives: Better surveillance to map the magnitude of chronic respiratory diseases and analyze their determinants with particular reference to poor and disadvantaged populations, and to monitor future trends. Primary prevention to reduce the level of exposure of individuals and populations to common risk factors, particularly tobacco, poor nutrition, frequent lower respiratory infections during childhood, and environmental air pollution (indoor, outdoor, and occupational). Secondary and tertiary prevention to strengthen health care for people with chronic respiratory diseases by identifying cost-effective interventions, upgrading standards and accessibility of care at different levels of the health care system.
