Knowledge about gestational diabetes mellitus amongst pregnant women in South Tamil Nadu

Aim: The aim of this study is to evaluate the knowledge of gestational diabetes mellitus (GDM), including risk factors, importance of screening and post-partum follow-up, amongst pregnant women attending antenatal care in maternity clinics in South India. Methodology: The study participants were recruited from two antenatal clinics in Chennai and a few primary healthcare centres in South India. A detailed questionnaire was used to obtain basic data regarding general awareness and knowledge about GDM and other issues related to screening, risk factors, monitoring, long-term consequences and post-partum follow-up. Education status was graded as illiterate, primary education, secondary education and graduates. A composite score for knowledge of GDM was calculated. Results: A total of 100 pregnant women attending antenatal clinics were interviewed, of whom 59 were from urban Chennai and the rest from Kanchipuram district. Regarding risk factors of GDM, 48.8% of rural women were unaware of any risk factor while 55.9% of urban women reported a family history of diabetes as a risk factor. 49.2% of urban women and 75.6% of rural women did not know the long-term consequences of GDM to babies born to GDM women. 50.8% (urban women) said GDM could lead to type 2 diabetes mellitus in future while only 45% of rural women were aware of this. Mean composite score increased with higher education with graduates in both urban and rural areas, scoring the highest. Conclusion: Knowledge about GDM is poor amongst pregnant women, especially in rural areas. This highlights the need for training physicians, paramedical people and the public regarding GDM.
