Gestational Diabetes and Postpartum Cardiovascular, Kidney, and Metabolic Disorders

Area of Science:

• Cardiovascular-Kidney-Metabolic (CKM) Disorders
• Reproductive Endocrinology
• Public Health

Background:

• Gestational diabetes (GDM) is a known risk factor for future cardiometabolic disorders.
• Limited postpartum data exists on the spectrum of cardiovascular-kidney-metabolic (CKM) disorders following GDM.

Purpose of the Study:

• To investigate the timing and extent of new-onset CKM disorders after pregnancy with GDM.
• To characterize postpartum cardiometabolic risk in women with a history of GDM.

Main Methods:

• Retrospective cohort study using the Merative MarketScan database (2007-2023).
• Included commercially insured females aged 12-55 with a single delivery and no prior CKM disorders.
• Followed participants postpartum for incident diagnoses of obesity, hypertension, hyperlipidemia, prediabetes, type 2 diabetes, metabolic syndrome, CKD, and CVD.

Main Results:

• Gestational diabetes was associated with significantly increased adjusted hazard ratios for type 2 diabetes (AHR, 10.02), prediabetes (AHR, 5.32), metabolic syndrome (AHR, 2.72), hyperlipidemia (AHR, 2.00), hypertension (AHR, 1.76), and obesity (AHR, 1.75).
• Elevated composite cardiovascular disease risk was observed (AHR, 1.28), but no significant association with chronic kidney disease.
• Crude incidence rates for multiple metabolic disorders were substantially higher in the GDM group.

Conclusions:

• Gestational diabetes significantly elevates postpartum risk for a range of metabolic disorders.
• Postpartum surveillance following GDM should encompass broader cardiometabolic risk assessment, not solely glucose monitoring.
• Findings underscore the need for comprehensive CKM disorder screening in the postpartum period for women with GDM.
