Resumo

Context The association between large for gestational age (LGA) phenotype, postnatal growth and cardiometabolic risk (CMR) in adult life remains unclear. The role of IGF1 genotype on LGA-related outcomes in adult life is unknown. Aim To assess the postnatal growth, IGF-I levels, CMR and the influence of the 737.738 IGF1 in adults born LGA. Subjects Case-control study (n = 515) nested in a population-based prospective cohort (n = 2063); 117 LGA and 398 gender-matched controls appropriate for gestational age (AGA) subjects. Methods Anthropometry was evaluated at birth, at 9-10 and at 23-25 years old. At the age of 23-25 years, blood pressure (BP), glycaemia, insulinaemia, homeostasis model assessment - insulin resistance, lipids, fibrinogen, and plasma IGF-I and 737.738 IGF1 polymorphism were assessed. Results Large for gestational age subjects remained heavier and taller than AGA at 9-10 and 23-25 years (P < 0.05); at 23-25 years, LGA had greater waist circumference (WC; P < 0.05) and higher BP (P < 0.05) than controls. Body proportionality at birth did not predict metabolic outcome. LGA subjects presenting catch-down of weight in childhood had lower body mass index (BMI; P = 0.001), lower WC (P < 0.05) and lower BP (P < 0.05) at 2325 years. 737.738 IGF-I genotype differed between groups (P < 0.001). Homozygosis for polymorphic alleles was associated with increased odds of LGA (OR: 3.2; 95% CI: 1.5-6.9), higher IGF-I (56.9 +/- 16.4 vs 37.7 +/- 16.0 nm; P < 0.01) and lower BP (114/68 vs 121/73 mmHg; P < 0.05). Conclusions Young adults born LGA presented higher BMI, WC and BP and appear to be at higher CMR risk than AGA subjects. The 737.738 IGF1 polymorphism appears to play a role on birth size and LGA-related metabolic outcomes. (AU)
