Background: Patients’ education and empowerment are essential parts of a disease management. Patients have to be educated on the disease as well as lifestyle changes that they need to practise for a holistic and consistent improvement in their disease status. This study examined patients’ knowledge on diabetes and nutrition as well as the role of dietician in the patient education. Methods: This was a cross-sectional study of patients aged more than 18 years, in a primary care centre in Kuala Lumpur. Patients responded to a pre-tested self-administered questionnaire which contains socio-demographic profiles of patients, knowledge on diabetes and nutrition. Patients were also asked on dietician consultation and the number of dietician visits. Patients were conveniently selected on the data collection days. Only consented patients and those who could understand Malay or English language were selected. Results: There were 110 patients who participated in the study. Overall the patients had good knowledge on diabetes and nutrition. The mean total knowledge score was 71.2% ± 9.34. Domains such as diabetes complications, exercise, meal practice, food sources and proportion need reinforcement. Only 60 (54.9%) patients had seen a dietician. Patients who had seen dietician showed significantly higher level of knowledge score (p=0.04). However frequent meeting with the dietician did not show any significant improvement in the knowledge (p=0.10). Factors such as patients’ gender, ethnicity, level of education, employment status, glycaemic level, duration of illness and body mass index did not show any significant association with the overall diabetic and nutrition knowledge. Conclusion: There is still a need to improve the overall diabetic education particularly in areas that patients were lacking such as diabetes complications, exercise, meal practice, food sources and proportion. It is equally necessary to encourage all diabetics to see a dietician since it helps to improve their level of knowledge as shown in this study.
