Stephen J. Kunitz and Jerrold E. Levy study the histories of those who have died as well as those who have survived since the first study was done. They show that, compared to those who have survived, the former were more likely to have been solitary drinkers and were on average younger at the time when they were first interviewed. The authors also present data for the entire Navajo population on changing mortality from alcohol-related causes from the 1960s to the present; they compare alcohol-related death rates among Navajos to those among rural Anglos in Arizona and New Mexico; they analyze two family histories--one of a family with severe alcohol problems, the other of a family with none--that illustrate how traditional patterns of wealth have shaped the way people have learned to use alcohol; they study the factors that may have led to the emergence of a solitary, unrestrained drinking style among some Navajos; and they describe the changes in treatment programs and the transformation of traditional healing systems as they are integrated into a bureaucratized health care system.
