GDM prevalence has been reported variably
from 1.4 to 14 percent worldwide and differently among
racial and ethnic groups(6-9). Prevalence rates are higher
in Black, Latino, Native American, and Asian women
than White women(2). By comparison, the presented
GDM prevalence of 7.06 percent was greater than
that of Serirat et al (2.02%) in a Thai population(10).
However, the number of samples was greater in the
previous study (N = 25,997) and the population
characteristics were also different. Regarding the 40
high-risk pregnancies missed for GCT screening, they
were treated as low-risk pregnancies without further
investigation and proper management. Fortunately,
there was no difference in pregnancy outcome
between this group and the other. The unscreened
high-risk cases in the present study may originate
from the inadequate history reviewing and the variation
of clinical competency from different levels
