Abstract
AIM
Women diagnosed to have Gestational Diabetes Mellitus (GDM) are at increased risk of developing diabetes in future. Thus, diagnosis of GDM is an important public health issue. In a random survey 16.2% of pregnant women were found to have GDM in the Chennai urban population. Hence we undertook a planned community based study to ascertain the prevalence of GDM.
MATERIALS AND METHODS
We conducted a prospective screening for GDM in the urban, semi urban and rural areas. All pregnant women irrespective of gestational weeks underwent a 75 g glucose challenge test in the fasting state. Diagnosis of GDM was made if the 2 hr plasma glucose was > or = 140 mg/dl (WHO criteria).
RESULTS
A total of 4151, 3960 and 3945 pregnant women were screened in urban, semi urban and rural areas, respectively. GDM was detected in 739 (17.8%) women in urban, 548 (13.8%) in semi urban and 392 (9.9%) in rural areas. Out of 1679 GDM women, 1204 (72%) were detected in first visit and the remaining 28% in subsequent visits. A significant increase (P < 0.0001) in the prevalence of GDM was observed with family history of diabetes, increased maternal age and BMI. A trend for increased prevalence of GDM was observed in women with less physical activity, however, not statistically significant.
CONCLUSION
In this community based study, the prevalence of GDM varied in the urban, semi urban and rural areas. Age > or = 25 years, BMI > or = 25 and family history of diabetes were found to be risk factors for GDM.
