Although the median serum level of FABP4 was similar in women with GDM (8030.0 pg/ml) and in healthy pregnant controls (9403.0 pg/ml (p = 0.67) (Table 1), it was significantly higher in women with BMI > 25 both in the GDM (15530.0 pg/ml vs. 2930.0 pg/ml; p < 0.0001) and control groups (12613.0 vs. 5730.0; p < 0.0001) compared to women with BMI < 25 (Figure 1(a)). This evidence concerns the gene FABP4 and gestational diabetes.
