Association between mean platelet volume and the risk of type 2 diabetes mellitus among women with history of gestational diabetes mellitus.

Abstract

Aims: The present study aimed to investigate the relationship between mean platelet volume (MPV) and the risk of type 2 diabetes mellitus (T2DM), among women with and without a history of gestational diabetes mellitus (GDM).

Methods: Eight thousand one hundred eighty-one parous women of the '2007-2018 National Health and Nutrition Examination Survey (NHANES)' were classified into GDM and non-GDM groups based on self-reported GDM history. We investigated the independent association between the MPV and the risk of T2DM in these groups via multivariable regression analysis. A subgroup analysis was done for the GDM group.

Results: After comprehensive adjustment for potential covariates, a significant positive correlation was observed between MPV and the risk of T2DM in women with a history of GDM (OR = 1.50, 95% CI 1.13-2.01, P = 0.006). There was a linear relationship between MPV and T2DM among women with a history of GDM, with each unit increase in MPV increasing the risk of T2DM by 50%. Subgroup analysis and interaction tests revealed a stronger significant effect on women with GDM history who had HbA1c ≥ 7%.

Conclusions: MPV is strongly associated with the incidence of T2DM among U.S. parous women with prior GDM, indicating that MPV may be a potential biomarker of T2DM among women with a history of GDM.
