Background: The prevalence of gestational diabetes (GDM) has been increasing along with the
obesity
pandemic. It is associated with pregnancy complications and a risk of type 2 diabetes.
Objective: To study nutrient intake among pregnant Finnish women at increased risk of GDM due to
obesity
or a history of GDM.
Design: Food records from obese women or women with GDM history (n=394) were examined at
baseline
(<20 weeks of pregnancy) of the Finnish Gestational Diabetes Prevention Study.
Results: The pregnant women had a mean fat intake of 33 en% (SD 7), saturated fatty acids (SFA) 12
en%
(SD 3), and carbohydrate 46 en% (SD 6). Sucrose intake among pregnant women with GDM history
was 7
en% (SD 3), which was different from the intake of the other pregnant women, 10 en% (SD 4) (p <.001).
Median intakes of folate and vitamins A and D provided by food sources were below the Finnish
national
nutrition recommendation, but, excluding vitamin A, supplements raised the total intake to the
recommended
level. The frequency of use of dietary supplements among pregnant women was 77%.
Conclusions: The observed excessive intake of SFA and low intake of carbohydrates among women
at
high risk of GDM may further increase their risk of GDM. A GDM history, however, seems to reduce
sucrose intake in a future pregnancy. Pregnant women at high risk of GDM seem to have insufficient
intakes of vitamin D and folate from food and thus need supplementation, which most of them already
take.
