N2 - Objective: To test the hypothesis that the first stage of labor will be longer in nulliparous and multiparous women with diabetes compared to non-diabetic counterparts. Methods: A retrospective analysis was performed from 228,668 deliveries between 20022008 from the Consortium of Safe Labor (National Institute of Child Health and Human Development, National Institutes of Health). Patients with spontaneous onset of labor from 37 0/7-41 6/7 weeks gestation were included (71,282) and classified as nulliparous or multiparous. Pregnancies were further subdivided regarding presence of preexisting diabetes (preDM) or gestational diabetes (GDM) and normal controls. Labor curves were created matching for body mass index (BMI) and neonatal birth weight. Statistical analysis was performed on descriptive variables using χ 2 with significance designated as p<0.05. Results: Among nulliparous patients, there were 118 women with preDM and 475 women with GDM; 25,771 patients served as normal controls. Among multiparous women, there were 311 with preDM, 1,079 with GDM and 43,528 in the control group. Although differences in dilatation rates were observed in nulliparous and multiparous women with and without diabetes, labor progression was similar between the subgroups when matched for maternal BMI and birth weight. Conclusions: Labor curves of women with preDM and GDM approximate those of non-diabetics, regardless of BMI, birth weight, or parity.
