Early diabetes screening in pregnancy

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Public Health

Background:

• Gestational diabetes mellitus (GDM) screening is crucial for maternal and fetal health.
• Current guidelines for early GDM screening vary, leading to inconsistencies in practice.
• Identifying optimal screening strategies for high-risk pregnancies remains a challenge.

Purpose of the Study:

• To review and evaluate current literature on early diabetes screening in pregnancy.
• To assess various screening guidelines, target populations, and diagnostic strategies.
• To highlight the advantages and disadvantages of different early screening modalities.

Main Methods:

• Comprehensive literature review of studies on early diabetes screening in pregnancy.
• Analysis of different screening targets, strategies, and diagnostic tests.
• Evaluation of existing guidelines and their validation status.

Main Results:

• No validated criteria exist for selecting high-risk pregnant women for early screening.
• Common screening methods (fasting plasma glucose, random plasma glucose, postload glucose, HbA1c) lack concordance and validation for early GDM diagnosis.
• The benefit of early screening through prompt treatment initiation has not been demonstrated.

Conclusions:

• Current evidence does not support any single strategy for early diabetes screening in pregnancy.
• Further randomized controlled trials are needed to validate screening methods and demonstrate treatment benefits.
• Standardized, evidence-based approaches for early GDM screening are currently lacking.
