Background: In spite various awareness programs, the awareness of diabetes mellitus (DM) and its complications among general population across the world, has remained low. Awareness of the disease is the cornerstone for desirable control and prevention or management of complications. Objectives 1. To study the awareness of DM among college-going non-medical post-graduate students. 2. To study the awareness on the complications of DM among college going non-medical post-graduate students. Materials & Methods: This descriptive questionnaire-based study was performed among 104 non-medical post-graduate students who fulfilled selection criteria. The structured and validated questionnaire assessed the knowledge on risk factors, early clinical symptoms, diagnosis, prevention of complications and treatment of diabetes. The responses with the score were tabulated and awareness was graded as poor (1-16 points), moderate (17-32 points) and good (33-48 points). Results: Among the selected 104, there were 44 male and 60 female participants. The awareness on DM among 86% was moderate, 13% was good and 1% was poor. Females tend to have better awareness on cause, symptoms and diagnosis of DM; whereas males had better awareness on its complications. The awareness of treatment of DM was poor in over half the participants. Conclusion: This study, among post graduate students showed moderate to poor awareness on diabetes and its complications. This observation raise doubt on the effectiveness of public health education programs on non-communicable diseases.
