According to the Centers for Disease Control, chronic diseases havebecome the leading cause of death and disability in the UnitedStates, account for 7 out of every 10 deaths and affect the qualityof life of 90 million Americans. In 2002, direct medical costsreached $92 billion and indirect costs (including disability, workloss and premature mortality) totaled $40 billion. Perhaps the mostconfounding fact is that although chronic diseases are among themost common and costly health problems, they also are among themost preventable.
