Amid growing recognition of the Developmental Origins of Health and Disease, maternal recall of infant birth weight has emerged as a mainstay of clinical research associating fetal exposures with subsequent health in childhood. Since studies at various offspring ages have noted the accuracy of maternal report of birth weight,1-3 it is widely assumed that the reliability of this recall is stable over time. However, to our knowledge, this assumption, which underpins the validity of a critical variable, has not been directly evaluated by repeated assessment of maternal recall over time. Thus, our objective was to evaluate the reliability of initial maternal recall of birth weight at 3 months post partum and the subsequent stability of recall at 3 years post partum.
