In Reply.—Although their rate of child abuse in infants weighing less than 2500 g certainly seems low and is reassuring clinically, it would be helpful to have a comparison figure for infants who weighed at least 2500 g and were demographically similar to the low-birth-weight infants. This figure would allow a true comparison of the rates of abuse in low-birth-weight and normal-weight infants. It also would be helpful to know the ages of the infants at the time that the authors checked the computer-generated list of abuse cases. Presumably, there Were still some very young infants who might be abused at some later date, and these cases would elevate the incidence of abuse. Finally, intensive psychosocial services for families of low-birth-weight infants might reduce the rate of child abuse, so it would be helpful to know what kinds of services were provided to such families in the London, Ontario, area.
