Early maternal weight gain as a risk factor for SGA in pregnancies with hyperemesis gravidarum: a 15-year hospital cohort study.

Background: Inadequate maternal weight gain increases the risk of small-for-gestational age (SGA) infants.

Recent studies have implied that weight gain during the first half of pregnancy is more crucial to pregnancy outcome than total weight gain.
