Postprandial blood-glucose-screening for gestational diabetes

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Public Health

Background:

• Gestational diabetes mellitus (GDM) poses risks to both mother and fetus.
• Effective screening protocols are crucial for early detection and management.
• Risk factors associated with GDM require further investigation in diverse populations.

Purpose of the Study:

• To evaluate the incidence and prevalence of gestational diabetes mellitus in a high-risk pregnant population.
• To assess the correlation between specific risk factors and the development of GDM.
• To analyze screening results from a 6-year period at a tertiary care center.

Main Methods:

• Screening of 1124 pregnant women with identified risk factors between 1985 and 1990.
• Diagnosis confirmation using postprandial glucose levels and a 75g oral glucose challenge test.
• Evaluation of risk factors including positive urinary glucose tests, poor obstetrical history, and family history of diabetes.

Main Results:

• Gestational diabetes mellitus developed in 24% of patients with positive urinary glucose.
• A 31% incidence was observed in patients with a poor obstetrical history.
• A 52% incidence of GDM was found in patients with a family history of diabetes.
• The overall incidence of GDM in the screened high-risk group was 34%.
• The prevalence of GDM in the general gravid population of Debrecen was 1.95%.

Conclusions:

• Specific risk factors significantly increase the likelihood of developing gestational diabetes mellitus.
• Routine screening for GDM in pregnant women with risk factors is essential for timely diagnosis.
• The findings highlight the importance of targeted screening strategies in obstetric care.
