Para los autores, estas cifras subrayan la importancia de extender los programas antitabáquicos y de aumentar la vigilancia sobre este hábito en todo el país, donde se estima que hay más de 46 millones de fumadores.
Los CDC consideran que el consumo de cigarrillos constituye la principal causa de muerte prevenible. Se calcula que cada año 440.000 estadounidenses mueren por cáncer de pulmón y otras enfermedades relacionadas con el tabaco.
El nuevo estudio muestra que más de 4,5 millones de fumadores y no fumadores presentaban bronquitis crónica en el año 2000, y más de 3 millones presentaban enfisema. No obstante, se trata de cifras conservadoras, basadas en encuestas, y a prevalencia puede ser muy superior, según opina Terry Pechacek, director científico asociado de los CDC.
Además, se estima que el coste económico del tabaquismo fue de 75.000 millones de dólares anuales en costes médicos directos y de 82.000 millones en pérdida de productividad.
