It has been customary to determine prematurity by birth weight alone, even though the shortcomings of this practice have been pointed out convincingly, for instance, by McKeown and Gibson.1 The World Health Organization has recently taken cognizance of this problem, realizing that its previous recommendation of a birth weight limit of 2,500 gm is but a temporary expedient while no better method is available to define, study, and manage prematurity. The new, brief report2 points out the numerical magnitude of the problem by stating that among infants of healthy, young primigravidae receiving good obstetrical care, only two-thirds of those weighing less than 2,500 gm are born before the thirty-eighth week.

Neonatal mortality statistics are frequently reported in 100-g increments of birth weight. We tabulated our mortality statistics using two methods of incrementation: 500 to 599 g, 600 to 699 g, 700 to 799 g, etc. (method A) and 501 to 600 g, 601 to 700 g, 701 to 800 g, etc (method B). In each 100-g weight group, the mortality was less using method B. The average reduction in mortality using method B was 4.1%. Use of the two different methods creates difficulty in making meaningful comparisons of various published reports. We recommend that all future studies use method A, as that method is more consistent with previous recommendations of the World Health Organization.
