Randomized Controlled Trial
Does behavioral intervention in pregnancy reduce postpartum weight retention? Twelve-month outcomes of the Fit for Delivery randomized trial.
Excessive weight gain during pregnancy is a risk factor for postpartum weight retention and future weight gain and obesity. Whether a behavioral intervention in pregnancy can reduce long-term weight retention is unknown. ⋯ A low-intensity behavioral intervention in pregnancy can reduce 12-mo postpartum weight retention and improve dietary restraint and self-weighing in study completers. Future research is needed to test the long-term effects of more intensive behavioral interventions in pregnancy. This trial was registered at clinicaltrials.gov as NCT01117961.

Low serum 25-hydroxyvitamin D [25(OH)D] concentrations during pregnancy have been associated with adverse pregnancy outcomes in a few studies but not in other studies. ⋯ Low 25(OH)D serum concentrations in the first trimester of pregnancy are not associated with adverse pregnancy outcomes and do not predict complications any better than routinely assessed clinical and maternal risk-factor information.
