Sangeetha M Kularatna YMSY Jayasundara PGCM Sureshkumar K 2025 10 7 4 Gestational diabetes mellitus (GDM) is glucose intolerance first recognized during pregnancy and is associated with short- and long-term adverse outcomes for both mother and child. Knowledge about GDM influences screening uptake, self-management, and postpartum follow-up. This study assessed prevalence indicators of GDM and evaluated knowledge regarding GDM among antenatal clinic attendees at District General Hospital (DGH), Kilinochchi. A descriptive cross-sectional study was conducted among 423 pregnant women. Data were collected using a structured questionnaire and recorded plasma glucose readings. Descriptive statistics were used. Fasting plasma glucose >95 mg/dL was observed in 35% of participants and 2-hour plasma glucose >140 mg/dL in 68%. Only 33% had ever heard of GDM, and family was the main source of information. Knowledge about screening, risk factors, complications, postpartum testing, and long-term child outcomes was generally poor. The findings highlight the need for structured antenatal education and strengthened health-worker counselling to improve GDM awareness and management in this setting.
