| Popis: | Implication of the IGF-IGF-binding protein (IGFBP) axis in the development of metabolic and cardiovascular diseases has been well documented. It has also been shown that an adverse intrauterine environment alters the IGF-IGFBP axis during childhood.The objective of this study was to investigate whether these alterations persist into adulthood.Fasting serum IGF-I, IGFBP-3, and insulin concentrations were measured, and their determinants were analyzed in a cohort of young adult subjects (22 yr of age) born either small (SGA; n = 461) or appropriate (AGA; n = 568) for gestational age.In adulthood, subjects born SGA had significantly lower mean serum IGF-I (320 +/- 137 vs. 348 +/- 143 microg/liter; P = 0.0015), IGFBP-3 (4700 +/- 700 vs. 4800 +/- 800 microg/liter; P = 0.04), and IGF-I/IGFBP-3 ratio (0.067 +/- 0.026 vs. 0.072 +/- 0.025; P = 0.01) than those born AGA. The fasting IGF-I concentration and the IGF-I/IGFBP-3 ratio were significantly inversely associated with age, body mass index, smoking, and oral contraception and were positively related to birth weight and fasting insulin levels. The IGFBP-3 concentration was significantly negatively correlated to age and smoking and was positively related to insulin concentration and oral contraception. After adjustment for age, height, body mass index, gender, smoking, and oral contraception, the mean IGF-I concentration and the mean IGF-I/IGFBP-3 ratio remained significantly lower in the SGA compared with the AGA group (P = 0.003 and P = 0.01, respectively).Serum IGF-I concentrations and the IGF-I/IGFBP-3 ratio are lower in adult subjects born SGA. Although the origin of this persisting alteration of the IGF-IGFBP axis in adulthood needs to be elucidated, its potential contribution to the long-term metabolic and cardiovascular complications associated with fetal growth restriction is important to consider in the future. |
