PERF News AAT deficiency emphysema, leading cause of death in United States, smoking and COPD, statistics on COPD one response
Sometimes numbers tell more than words. Here are statistics on COPD, found on the American Lung Association website:
- Over 12 million adults in the U.S. have been diagnosed with COPD; twice that number have problems with lung function but have yet to be diagnosed with COPD.
- Emphysema affects 4.7 million Americans, 92% of whom are 45 or older.
- For the past eleven years, more women than men have died from COPD.
- Emphysema now is diagnosed in more women than men.
- Twice as many women as men are diagnosed with chronic bronchitis.
- The biggest risk factor for COPD is smoking, accounting for about 80% of COPD deaths. Other risk factors are air pollution, second hand smoke, dusts and chemicals on the job, heredity, childhood respiratory infections, and socioeconomic status.
- A gene that causes a deficiency of alpha1-protease inhibitor, a lung protector produced by the liver, causes alpha1 antitrypsin deficiency-related (AAT) emphysema. About 100,000 Americans, mostly of northern European descent, have AAT deficiency emphysema. This gene is carried by approximately 20 million Americans, and 116 million people worldwide.
- More than half of hospitalizations for COPD are for people age 65 and older.
- At least half of COPD patients experience limitations in ability to work, do household chores, engage in social and family activities, and sleep.
