To the Editor: In a report on the association of overweight and obesity with all-cause mortality,1 the authors' conclusions are incomplete because 2 major implications of the findings were not addressed.
First, the subgrouping by age showed that the association between obesity and mortality was attenuated with higher age. In fact, none of the various categories of BMI remained significantly associated with mortality in patients aged 65 years or older.
