Journal ArticleDOI
Association between postnatal catch-up growth and obesity in childhood: prospective cohort study.
TL;DR: In this contemporary well nourished cohort, catch-up growth was predicted by factors relating to intrauterine restraint of fetal growth, and children who showed catch- up growth between zero and two years were fatter and had more central fat distribution at five years than other children.
Journal ArticleDOI
Size at Birth and Early Childhood Growth in Relation to Maternal Smoking, Parity and Infant Breast-Feeding: Longitudinal Birth Cohort Study and Analysis
TL;DR: Early postnatal growth rates are strongly influenced by a drive to compensate for antenatal restraint or enhancement of fetal growth by maternal-uterine factors, particularly in breast- and bottle-fed infants.
Journal ArticleDOI
Association of the INS VNTR with size at birth
David B. Dunger,Ken Ong,Stewart J. Huxtable,Andrea Sherriff,Kathryn A. Woods,Marion L. Ahmed,Jean Golding,Marcus Pembrey,S M Ring,Simon T. Bennett,John A. Todd +10 more
TL;DR: In a cohort of 758 term singletons followed longitudinally from birth to 2 years, significant genetic associations with size at birth were detected: class III homozygotes had larger mean head circumference than class I homozygote, and were also evident for length and weight at birth.
Journal ArticleDOI
Cord blood leptin is associated with size at birth and predicts infancy weight gain in humans
Ken K. Ong,Marion L. Ahmed,Andrea Sherriff,Katie A. Woods,A. Watts,Jean Golding,David B. Dunger +6 more
TL;DR: The data support a role for leptin in the regulation of infancy weight gain, and suggest a mechanism whereby infants may 'catch-up' in growth postnatally following an adverse intrauterine environment.
Journal ArticleDOI
Longitudinal study of leptin concentrations during puberty: sex differences and relationship to changes in body composition.
Marion L. Ahmed,Ken K. Ong,David J. Morrell,Les Cox,Nick M Drayer,Leslie A. Perry,Michael A. Preece,David B. Dunger +7 more
TL;DR: In girls, but not in boys, low leptin levels during prepuberty (B1) predicted subsequent gains in the percent body fat during puberty (r = -0.75; P = 0.005), and the sexual dimorphism in leptin Levels during puberty reflects differential changes in body composition.
