These patients underwent a third-trimester 3-hour glucose tolerance test (GTT) or glucose panel. The primary outcome was a new diagnosis of GDM; secondary outcomes included delivery mode, live birth, shoulder dystocia, respiratory distress syndrome (RDS), preeclampsia, neonatal hypoglycemia, and neonatal intensive care unit (NICU) admission.<\/jats:p>\n                  <jats:p>Of 723 patients, 169 (23.4%) were newly diagnosed with GDM. Among those with specific sonographic findings, GDM was identified in 25.4% (EFW &gt;90%), 24.4% (AC &gt;95%), and 21.2% (polyhydramnios). GDM was diagnosed in 19.5% with one sonographic finding, 25.5% with two, and 26.9% with all three. New third-trimester GDM was significantly associated with increased neonatal hypoglycemia (30.4%; p\u2009&lt;\u20090.001), RDS (10.8%; p\u2009=\u20090.037), and NICU admission (13.4%; p\u2009=\u20090.036).<\/jats:p>\n                  <jats:p>Up to one in four women with third-trimester findings of EFW &gt;90%, AC &gt;95%, or polyhydramnios\u2014despite a prior negative screen\u2014were newly diagnosed with GDM. These cases were also linked to higher neonatal morbidity. Targeted third-trimester GDM screening in patients with these sonographic markers may help identify at-risk pregnancies and improve perinatal outcomes.<\/jats:p>","DOI":"10.1055\/a-2889-6325","type":"journal-article","created":{"date-parts":[[2026,6,6]],"date-time":"2026-06-06T00:48:13Z","timestamp":1780706893000},"source":"Crossref","is-referenced-by-count":0,"title":["Sonographic
