Objective: To determine the prevalence of gestational diabetes mellitus (GDM) before 24 week of gestational age in pregnant women with clinical risk factors for GDM at Taksin Hospital, Bangkok Metropolitan Administration

Study design: Cross-section study.

Subjects: Three hundred and eighty five pregnant women with at least 1 clinical risk factor(s) for GDM visiting antenatal care clinic at Taksin Hospital, Bangkok Metropolitan Administration were screened for GDM during August 2005 to March 2006.

Methods: Age, body weight, height, clinical risk factors for GDM, gestational age, 50 g GCT results and 100 g OGTT results were collected and analyzed.

Main outcome measures: Prevalence of GDM before 24 week of gestational age in pregnant women with clinical risk factors for GDM

Results: Prevalence of GDM before 24 week of gestational age was 11.2% (95%CI:  8.2-14.7). Mean gestational age at diagnosis was 12.8+4.9 weeks. Maternal age was the only clinical risk factor for GDM. Pregnant women having more than 1 clinical risk factor were increased in incidence of GDM with the odds ratio of 2.3 (95% CI:  1.2-4.4).

Conclusion: The prevalence of GDM in this study was 11.2% and GDM was detected earlier at 12.8 weeks.
