Preterm Growth Restraint: A Paradigm That Unifies Intrauterine Growth Retardation and Preterm Extrauterine Growth Retardation and Has Implications for the Small-for-Gestational-Age Indication in Growth Hormone Therapy
article
Small for gestational age (SGA) is defined as a birth weight and/or length >2 SDs below the gender-specific population reference mean for gestational age. However, there is confusion about various aspects of this term, as recently discussed.1,2 The term “intrauterine growth retardation” (IUGR) is often used for the same condition but preferably should be restricted to poor growth during pregnancy according to intrauterine growth diagrams used in obstetrics.3 SGA after a normal duration of gestation (37–42 weeks) is usually followed by rapid growth after birth (catch-up growth). It has been demonstrated that almost 90% of term SGA infants catch up in height in the first 2 years of postnatal life.4,5
