In Reply: Dr Liew and colleagues raise the question of whether birth weight or length of gestation is the more appropriate predictor when exploring the hypothesis of fetal origins of adult disease. While birth weight is a more accurate and reliable measure than gestational age, we chose to examine the association of gestational age with long-term survival because we believe that it may be a stronger as well as a more fundamental predictor of postnatal maturity and, therefore, long-term survival.1
