Growth and Metabolic Consequences in Children Born with Small for Gestational Age at Term Gestation.

The purpose of this study was to assess the growth status and to evaluate the factors affecting the development of metabolic syndrome in children born with small for gestational age (SGA) at term gestation. METHODS:We retrospectively reviewed medical records of 73 (36 boys, 37 girls) children born with SGA at term gestation who were visited for short stature and metabolic problems at Seoul National University Children' Hospital between 1994 and 2003. We assessed several clinical parameters as follows:birth weight, height standard deviation score (SDS), weight SDS, weight for height, bone age (BA), chronologic age (CA), predicted adult height (PAH) and midparental height (MPH). We evaluated the factors affecting height SDS according to pubertal status. We also evaluated the factors affecting development of type 2 diabetes mellitus, dyslipidemia or obesity.
Pubertal children had greater height SDS, weight SDS and difference between BA and CA than prepubertal children, respectively (P<0.05). Height SDS positively correlated with difference between BA and CA (r=0.43, P<0.01), but BA advancement (BA>CA) was not observed in prepubertal children. BA advancement was observed in all pubertal children except one. The children who had greater weight SDS than height SDS had significantly lower height SDS and delayed BA, respectively (P<0.05). The children who had metabolic problems had higher weight SDS (P<0.05).
This study suggests that rapid skeletal maturation may develope during transition from prepuberty to puberty and catch-up growth may contribute to the development of metabolic syndrome in children born with SGA, but further study will be required.
