FIG. 2.

Average weight gain (in kilograms) among obese women diagnosed with GDM, based on their timing of GDM screening and GDM diagnosis. The three screening groups are: Early Only screened positive and treated early; Early and Usual screened negative early then positive for GDM with usual screening; Usual Only were eligible for early screening as obese but did not have GDM screening and diagnosis until later in pregnancy. Obese women diagnosed with EarlyGDM in the Early Only screening group (and thus received early treatment, including lifestyle management) was the only group that had average weight gain that was within IOM weight gain guidelines of 5–9 kg (EarlyGDM women gained a mean of 8.1 kg) and was weight neutral in the first trimester (−0.2 kg).
