title: Short-term and long-term sequelae in intrauterine growth retardation (IUGR).
abstract: Intrauterine Growth Retardation (IUGR) is defined as a rate of growth of a fetus that is less than normal for the growth potential of the fetus (for that particular gestational age). Small for Gestational Age (SGA) is defined infant born following IUGR, with a weight at birth below the 10th percentile.Suboptimal fetal growth occurring in IUGR fetuses is an important cause of perinatal mortality and morbidity. The acute neonatal consequences of IUGR include metabolic and hematological disturbances, and disrupted thermoregulation; in addition, respiratory distress (RDS), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP) may contribute to perinatal morbidity. Metabolic disturbances are related to glucose and fatty acid metabolism. It is well-known that individuals who display poor growth in utero are at significantly increased risk for type 2 diabetes mellitus (T2DM), obesity, hypertension, dyslipidemia, and insulin resistance (the so-called metabolic syndrome, MS). MS ultimately leads to the premature development of cardiovascular diseases. In addition, short stature in children and adults, premature adrenarche, and the polycystic ovarian syndrome (PCOS) are endocrinological sequelae of IUGR. (8) Early onset growth delay and prematurity significantly increase the risk for neurological sequelae and motor and cognitive delay.Future prospective studies need to investigate risk factors for infants who are SGA. If reliable prediction can be achieved, there is potential to reduce future perinatal morbidity and mortality, and long term consequences among SGA babies.
