Regarding Dr. Nishioka's first concern, we doubt that we substantially overestimated the importance of older age as a risk factor for death. Sudanese staff estimated the ages of patients and commonly considered factors in addition to physical appearance (for example, for a woman, the ages and number of her children and the timing of her marriage [that is, menarche] with respect to a political or military event).
In our multivariable analysis of the risk for death among adults, we avoided making assumptions about the relation between age and death by treating age as a series of independent binary variables instead of a continuous variable. Each age category was then independently compared with the referent group (patients 18 to 24 years of age); all adults 45 years of age and older were included in the same category. As shown in the second column of Table 1, the approximate risk ratio for death progressively increases as age increases. This relation persists if we deduct an arbitrary 5 years from the ages of all adults who died (third column) or of all markedly malnourished adults (regardless of whether they lived) who had a body mass index less than 14 kg/m2 (fourth column).
