description: | Aims/hypothesis The aim of the study was to compare longitudinal changes in insulin sensitivity (S I ) and beta cell function between women with and without a history of gestational diabetes mellitus (GDM). Methods The prospective follow-up cohort included 235 parous non-diabetic Mexican–American women, 93 with and 142 without a history of GDM. The participants underwent dual-energy x-ray absorptiometry, OGTTs and IVGTTs at baseline and at a median of 4.1 years follow-up. The baseline values and rates of change of metabolic measures were compared between groups. Results At baseline, women with prior GDM (mean age 36.3 years) had similar values of S I but higher percentages of body fat and trunk fat ( p ≤ 0.02), a lower acute insulin response and poorer beta cell compensation (disposition index [DI]) ( p 0.50). Adjustment for baseline age, adiposity, calorie intake, physical activity, age at first pregnancy, additional pregnancies and changes in adiposity during follow-up increased the between-group differences in the rates of change of S I and DI ( p ≤ 0.003). Conclusions/interpretation Mexican–American women with recent GDM had a faster deterioration in insulin sensitivity and beta cell compensation than their parous counterparts without GDM. The differences were not explained by differences in adiposity, suggesting more deleterious effects of existing fat and/or reduced beta cell robustness in women with GDM. |
