To the Editor: In examining the relationship of dietary sodium intake and health outcome, Dr He and colleagues1 have refined and extended our earlier analysis2 of the long-term mortality experience of the National Health and Nutrition Examination Survey (NHANES) participants. Their findings support our prediction that the nature of this relationship would be affected by other patient characteristics. Indeed, He et al now report that, in the obese minority of a subset of the entire NHANES population, increased sodium intake was associated with increased mortality. This was not true in the majority (72%) who were not obese.
