The mother’s weight at term (at 35 full weeks or later) was recorded.
GWG was defined as weight at term minus self-reported
weight at the beginning of pregnancy. GWG was used as a continuous
variable and stratified according to the current recommendations
by the IOM: less than 5 kg, 5–9 kg, and more than 9 kg for obese
women; and less than 11 kg, 11–16 kg, and more than 16 kg for normal
weight women [14].
