Small-for-gestational-age (SGA) definitions and associated risks
1National Institute of Public Health, Norway.
Samples and methods vary in constructing birthweight charts. Introduction of ultrasound dating affects the distribution of gestation, increases the proportion of preterm births, and reduces postterm and small-for-gestational-age (SGA) births. The need for standardized charts is emphasized. Preferably such charts ought to be sex- and parity-specific, also taking into account the mother's previous pregnancy outcome in terms of birthweight. The risks associated with being born SGA involve various morbidity as well as short- and long-term survival.
