Serum retinol-binding protein 4 (RBP4) and retinol in a cohort of borderline obese women with and without gestational diabetes.

Abstract Objectives To evaluate whether serum RBP4 correlates with gestational diabetes mellitus (GDM) in a cohort of borderline obese (BMI > 30) pregnant women. Design and methods Serum RBP4 and retinol were measured in pregnant women with ( n  = 12) and without ( n  = 10) GDM. Results RBP4, retinol and RBP4:retinol molar ratio were not different between the groups and were not associated with markers of insulin resistance. Conclusions GDM is not associated with RBP4 or retinol among borderline obese pregnant women.
