Context: Fetal development is thought to be gender specific for adiposity and circulating insulin and IGF-I but not adipokinemia, as judged by serum visfatin and adiponectin at term birth. We studied the potential relationship between these gender specificities and fetal growth.

Setting: The study was conducted at a university hospital.

Study Population: Subjects included 96 strictly matched neonates born appropriate for gestational age (AGA; 24 girls, 24 boys) or small for gestational age (SGA; 24 girls, 24 boys).

Main Outcomes: Outcomes included serum insulin, IGF-I, visfatin, total and high-molecular-weight (HMW) adiponectin, osteocalcin at term birth, and neonatal body composition by absorptiometry.

Results: Cord insulin and IGF-I levels were higher in girls than boys (P ≤ 0.01), in both the AGA and SGA subpopulation. In AGA newborns, fat and lean mass …
