Maternal age showed a statistically significant association with gestational age at birth (P=0.041).This suggests that women with GDM not requiring induction of labour were significantly more likely to give birth at post dates (P=0.004), also positively correlated with increasing maternal age (P=0.041).There was different distribution of BMI groups in the 40 weeks’ gestation, which was statistically significant at P=0.004.Data for GDM women with and without induction of labour were compared for the three BMI groups. For the 331 women with GDM, a highly statistically significant (P
