Study Finds Newborn Outcomes Affected by Blood Glucose Levels During Pregnancy

JAMA. 2007;298(6):613-614. doi:10.1001/jama.298.6.613

Chicago—Blood glucose levels in pregnant women that are elevated but still within the normal range can increase risks for newborns that have traditionally been associated with overt gestational diabetes. That was the conclusion of the international Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study, presented here at the recent American Diabetes Association's 67th Scientific Sessions.

Experts expect that the study's results could alter diagnostic and treatment practices related to maternal glycemia. “These data show clearly that there are associations between blood sugar levels and outcomes in [pregnant women] whose levels aren't high enough to be called diabetes,” said principal investigator Boyd Metzger, MD, of the Northwestern University Feinberg School of Medicine, in Chicago. “Therefore, there's benefit for them to be tested,” he said.
