Prepregnancy Consumption of Fruits and Fruit Juices and the Risk of Gestational Diabetes Mellitus: A prospective cohort study

Diabetes Care, 03/30/2012

The data suggest that prepregnancy higher consumption of whole fruits is not associated with an increased gestational diabetes mellitus (GDM) risk. The association between fruit juices and GDM risk appears to be nonlinear.


  • A prospective study among women with at least one singleton pregnancy in the Nurses’ Health Study II from 1991 to 2001.


  • Among 13,475 women, 860 reported a first diagnosis of GDM.
  • The adjusted relative risks (RRs) for GDM from the lowest to highest quintile of whole fruit consumption were 1.00 (referent), 0.80 (95% CI 0.65–0.98), 0.90 (0.73–1.10), 0.80 (0.64–1.00), and 0.93 (0.76–1.16), respectively.
  • The corresponding RRs for fruit juice were 1.00, 0.82 (0.66–1.01), 0.78 (0.63–0.96), 0.84 (0.68–1.04), and 1.00 (0.81–1.23).
