In our follow-up study waist circumference was greater
in women with a history of GDM when compared to controls,
but interestingly so also in the women who proceeded
to prediabetes or diabetes in the subgroup of women progressed
with GDM to abnormal glucose tolerance versus
those with GDM and normal glucose tolerance after pregnancy.
Waist circumference is closely associated with lifestyle,
and worryingly, some of the previous studies have
shown that although most women would be aware of the
risk of subsequent risk of diabetes after a GDM pregnancy,
very limited lifestyle changes concerning the eating habits,
weight reduction and/or the level of physical exercise
unfortunately occur [18,19].
