a b s t r a c tAlthough nutrition education for diabetes patients is the responsibility of dieticians and/or nutritionist, nurses have an important role to play. This study measured the knowledge level of nurses' and associated factors in the nutritional management of diabetes. In this cross-sectional study a sample of 200 nurses completed a 21-item nutritional management of diabetes knowledge test developed based on the ADA and WHO guidelines for the nutritional management of diabetes. Using Cronbach's alpha, reliability was 0.62. The nurses (n = 200) had almost a 1:1 male to female ratio (n = 99, 49.5% and n = 101, 50.5%) and a mean age of 27.24 ± 3.66 years. Total mean score was 12.13 ± 3.17 (44.9% correct). Over 70% of the nurses said diabetes patients could exclude any of the major nutrients from their meals. Almost 90% (n = 179) of the nurses did not know the recommended daily caloric intake of carbohydrates for diabetes patients. Higher mean scores were found in nurses who have ever had a refresher course in nutrition, ever counseled a diabetes patient and took 2-3 nutrition courses during school. Nurses' knowledge in the nutritional management of diabetes was poor. It raises questions about the adequacy of nurses' knowledge in the nutritional management of diabetes.
