　　Dawn Demeo is an assistant professor at Harvard Medical School in Massachusetts.

　　DAWN Demeo: "By two thousand and twenty, C.O.P.D. will likely be the third leading cause of death across the world."

　　C.O.P.D. is a new name for emphysema and chronic bronchitis. These are the two most common forms of the disease. Many people with C.O.P.D. have both of them.

　　VOICE ONE:

　　Doctor Demeo wrote about a study by a team from Harvard's Brigham and Women's Hospital and the University of Bergen in Norway. The study adds to findings that women may be more at risk than men for the damaging effects of smoking.

　　The team examined results from a Norwegian study of more than nine hundred people with C.O.P.D. Inga-Cecilie Soerheim also wrote about the team's findings. She says they show that women suffered the same severity of C.O.P.D. as men. But, the female smokers were younger and had smoked a lot less.

　　VOICE TWO:

　　The team also looked at two groups among the people in the study. These were people under the age of sixty and those who had smoked for less than twenty years. In both cases, women had more severe C.O.P.D. and a greater loss of lung function than men.
