Inadequate weight gain during pregnancy is an important risk factor for low birth weight (LBW), but the contribution of diet to weight gain is uncertain.
Pregnancy weight gains were examined at 4-week intervals from 12 to 36 weeks' gestation, as well as total gain for gestation, in a cohort of over 2000 young pregnant women, aged <=18 at entry to prenatal care.
The effect of diet was studied in a 15% random sample of the cohort, using a 24-hour dietary recall obtained at entry to prenatal care (averaging 17 weeks' gestation).
As early as 16 weeks' gestation, gains below the lower limit of a clinical standard were associated with a decrement in birth weight at delivery of more than -85 g, and after 24 weeks of approximately -180 g.
