Due during the past 20 years.[2,5- 10] All studies

Due to the importance of early detection and treatment of GDM knowing the
prevalence of it in the community will help to focus more on it and point out if this
community has an increasing risk factors to have it . Which is finally will lead to help
in reducing those risk factors . Established risk factors for GDM are advanced
maternal age, obesity, and family history of diabetes1 the prevalence of GDM
differs around the world , In Australia, GDM prevalence was found to be higher in
women whose country of birth was China or India than in women whose country of
birth was in Europe or Northern Africa2 . In Europe, GDM has been found to be
more common among Asian women than among European women 3 In India, GDM
has been found to be more common in women living in urban areas than in women
living in rural areas 4 and in another data showing that GDM prevalence has
increased by ?16–127% in several race/ethnicity groups during the past 20 years.2,5-
10 All studies of trend in GDM conducted in different populations and with different
methodologies consistently reported an increase in GDM in all race/ethnicity groups,
suggesting that the observed increase in GDM prevalence may be true. However,
none of the six studies could distinguish between women who have been reclassified
postpartum as having underlying diabetes from those who returned to normal glucose
tolerance. Higher relative increases in younger women suggest that the prevalence of
risk factors for GDM may have increased more in younger women than in older
women. However, none of the studies had information on maternal obesity, the most
important modifiable risk factor for GDM 11 It is critical to know the risk factors
for GDM not only to better understand trends in GDM, but also to allow early
identification of women at risk and prevention of this common pregnancy
complication. Whatever the underlying reason for the observed increases in the
prevalence of GDM, the health care system is faced with an increase in GDM.
Therefore, this pregnancy complication will require increased resources to manage
appropriate glycemic control during pregnancy and reduce adverse perinatal outcomes
In addition, ?50% of women with GDM are expected to develop type 2 diabetes
within 5 years of the index pregnancy 12 In conclusion, a true increase in the
prevalence of GDM, aside from its adverse consequences for infants in the newborn
period, might reflect or contribute to the ongoing pattern of increasing diabetes and
obesity. The possible long-term effects of the increase in GDM on the immediate
offspring will not be known for decades. Access to health care and quality care for
GDM women and their offspring need to be more widely available. Therefore,
coordinated efforts are required to alter these trends in GDM and to prevent chronic
diabetes in GDM patients and their offspring.
