Early Puberty: Rapid Progression and Reduced Final Height in Girls With Low Birth Weight

Abstract

The timing of menarche and the level of final height in Catalan girls with early onset of puberty was found to depend on prenatal growth. Girls with normal birth weight tend to progress slowly through puberty with a normal timing of menarche and normal final height. In contrast, girls with low birth weight tend to progress relatively rapidly to an early menarche and to a reduced final height. If these findings are confirmed in other ethnic and/or larger groups, then a subgroup has been identified that will most likely benefit from any therapeutic intervention aiming at a delay of pubertal development and/or an increase of final height.
