title: Some comparative aspects of a longitudinal growth study in normal Spanish children and other longitudinal studies.
abstract: The differences existing among some european longitudinal growth studies make it necessary to be cautious in the use of standards constructed on different populations. The improvement of the environmental conditions during the last 20 years is probably the most important cause of the "catch-up" phenomenon of the spanish stature. It is probable that racial characteristics also play a role, even in the same country as can be appreciated on comparing two spanish longitudinal studies based on children originally from different regions. All of which indicates the need to use own standards in those countries which, like ours, have lived through a period of intense changes. Even exploratory studies of regional differences in the same country seem necessary.
