The relationship between previous breastfeeding duration and
intensity with the glucose tolerance test result
The relationship between breastfeeding duration and intensity with the
glucose levels from the OGTT at the subsequent pregnancy were also
analysed. After adjusting for confounders (medical treatment of GDM in
first pregnancy, BMI, maternal age at second pregnancy, ethnicity),
breastfeeding greater than six months was associated with a lower mean
OGTT at 1 h (P = 0.01) and women in the high intensity
breastfeeding group had a lower 2 h blood glucose result (P =
0.01) with a mean decrease of 0.66 mmol/L (Table 4).
