The data presented by Hosam Kamel, MD, and Mohammad Iqbal, MD, support the finding of our study that only a low BMI is a significant predictor of shortened survival in hospitalized elderly patients.1 These data also indicate that the optimal weight for lowest mortality in such a population increases with increased age. A comparison of present and previous analyses suggests that treating overweight conditions should be avoided in hospitalized older patients. However, we would remark that these results should be interpreted with caution because of several methodological limitations.
