Farabi SS, et al. - In this investigation, researchers tested the novel premises that obstructive sleep apnea (OSA) is positively correlated with 24-hour patterns of glycemia and insulin resistance (IR) in pregnant women with obesity despite dietary control. A standardized diet was provided for pregnant women with obesity while wearing a continuous glucose monitor for 3 days. Findings revealed that mild OSA is common in obese pregnant women and correlated with higher glycemic profiles, fasting free fatty acids (fFFA), and hepatic IR estimates. OSA is an undervalued but potentially treatable target for optimizing the outcomes of maternal glycemia and metabolism, the supply of fetal fuel and pregnancy.
