  • *

    * Pregnancies that resulted in a single live birth (n = 2,347; GDM n = 109, no diabetes n = 2,238). Pregnancies resulting in multiple births were excluded: 39 participants reported more than one baby in last pregnancy; 38 participants reported having twins (GDM n = 2, no diabetes n = 36), and 1 participant reported having triplets (no diabetes).

  • Nonroutine medical problems in pregnancy were in addition to the report of GDM and included any of the following: anemia in pregnancy, preeclampsia, toxemia, weak or incompetent cervix, water retention or edema, vaginal bleeding or spotting in the first 6 months, vaginal spotting or bleeding after the first 6 months, or other nonspecified problem.
