To the Editor: In March 2004, we published
an article1 that showed that a large proportion
of deaths each year in the United States result from modifiable lifestyle-related
behaviors. We are writing to inform the JAMA readership
that through an error in our computations, we overestimated the number of
deaths caused by poor diet and physical inactivity. Our principal conclusions,
however, remain unchanged: tobacco use and poor diet and physical inactivity
contributed to the largest number of deaths, and the number of deaths related
to poor diet and physical inactivity is increasing.
