title: Birthweight and stature, body mass index and fat distribution of 14-year-old Polish adolescents.
abstract: OBJECTIVE
  The relationships between intra-uterine growth retardation and stature, relative weight and fat distribution at adolescence have not been comprehensively established. The aim of this report is to assess the effect of low birthweight on stature, relative weight and fat distribution in 14-year-old boys and girls from Wroclaw, Poland.
  
  
  METHODS
  Cross-sectional measurements of 1197 boys and 819 post-menarcheal girls aged 13.50-14.49 years were performed during medical examinations in 1997. Stature, body mass index (BMI; kg/m2), waist-to-hip ratio (WHR) and waist-to-thigh ratio (WTR) were used in the present study. A cut-off value of the 10th percentile of birthweight for particular gestational weeks was used in order to define subjects born small for gestational age (SGA) or appropriate for gestational age (AGA). Two-way ANOVA was used to evaluate the effect of birthweight on anthropometric variables of 14-year-old adolescents, allowing for socioeconomic status (determined by the level of the mother's education).
  
  
  RESULTS
  Birthweight affected stature in boys and girls (P < 0.001), BMI in boys (P < 0.05) and WHR and WTR in girls (P < 0.001 and P < 0.05, respectively). At the age of 14 years, both SGA boys and girls were shorter than their AGA peers. The SGA boys had lower BMI, whereas SGA girls accumulated more centralized fat compared with their AGA counterparts.
  
  
  CONCLUSIONS
  Fetal growth retardation has a long-lasting adverse effect on later physical growth. Polish SGA children do not catch up with their peers in terms of stature by adolescence. Moreover, central fat distribution, as observed among SGA girls, constitutes a significant risk for several adult degenerative diseases.
