Poster Session III
In the main analysis (n=1563), 826, 327, 249, 118, and 43 women had 0, 1, 2, 3 or 4 abnormal values, respectively. After adjusting for maternal age, parity, chronic hypertension, and pre-pregnancy BMI, 1 abnormal GTT value was associated with a decreased risk of CD with an aOR of 0.71 (95% CI 0.54-0.93). The odds of NICU admission was increased only for those with 3 or 4 abnormal values (aOR 2.26, 95% CI 1.49-3.44 and aOR 2.82, 95% CI 1.49-5.36, respectively) (Table 1).
In the sub-analysis (n=1153), 82 and 245 had 1 abnormal fasting and 1 abnormal non-fasting value, respectively. Those with only 1 abnormal fasting value did not have an increased risk of CD, NICU admission, or LGA (Table 2).
Conclusion: Having 1 abnormal early GTT value is not associated with adverse neonatal outcomes but is associated with decreased CD. This data adds to growing evidence against early GDM screening.
