Abstract

Purpose

Women with prior gestational diabetes mellitus (GDM) are at higher risk of type 2 diabetes (T2D). The aim of this study was to investigate the association between fruit and vegetables (FV) intake and abnormal glucose tolerance (AGT) among women with prior GDM.

Methods

A total of 281 women with prior GDM have been recruited a mean of 6 years after their pregnancy in this cohort study. FV intake was obtained with a validated food frequency questionnaire (FFQ). Anthropometric and glycemic components were measured during their clinical visit and women were stratified according to normal glucose tolerance (NGT) or AGT.

Results

A cross-sectional analysis showed that a total of 155 women had NGT and 126 AGT. Women with AGT had significantly lower FV (6.5 ± 0.2) and vegetables servings (3.9 ± 0.2) and tended to have lower fruit servings (2.6 ± 0.2) than women with NGT (7.4 ± 0.2, 4.5 ± 0.2 and 3.0 ± 0.1, respectively) (p = 0.001, p = 0.04 and p = 0.10, respectively, adjusted for age and BMI). FV intake, per one serving increase, was associated with a reduced likelihood of having AGT [OR = 0.88 (0.81–0.97) after adjustment for age and BMI]. Vegetables or fruit intake tended to be associated with a reduced likelihood of having AGT [OR = 0.88 (0.78–1.00) and OR = 0.88 (0.76–1.02), respectively, after adjustment for age and BMI].

Conclusions

Higher intake of FV may be associated with a lower likelihood of AGT among women with prior GDM. Further studies are needed to confirm these results in this high-risk population.
