Women who eat higher amounts of whole fruits prior to pregnancy do not have increased risk of gestational diabetes mellitus, and association between fruit juice consumption and gestational diabetes appears to be nonlinear, study says
April 3, 2012
Examine the association of prepregnancy habitual consumption of fruits and fruit juices and gestational diabetes mellitus (GDM) risk.
RESEARCH DESIGN AND METHODS
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).
These data suggest that prepregnancy higher consumption of whole fruits is not associated with an increased GDM risk. The association between fruit juices and GDM risk appears to be nonlinear.
