The association with increased UACR was significant with the combination of a GDM history and a subsequent diabetes diagnosis, but not individually. The increased eGFR, however, remained significant after adjustment even for women with only a history of GDM, regardless of whether they later developed diabetes or even prediabetes.
“The independent association of GDM with eGFR also remained significant when we excluded women with conditions that might influence renal function markers at follow-up, including type 1 diabetes, preeclampsia/eclampsia or any hypertension complication during the index pregnancy, regular use of cholesterol-lowering drugs, or recent use of ACE inhibitors, diuretics, or H2 blockers,” the authors reported.
“Furthermore, no effect modification was observed when we stratified the analyses by clinical and lifestyle characteristics at follow-up, including current BMI, smoking, antihypertension medication use, family history of diabetes, physical activity, and median time since index pregnancy. Associations in some strata became statistically insignificant due to reduced sample size [all P for interaction = .05],” they wrote.
