The study aimed to determine the level of awareness and to assess compliance to Diabetes management of adolescents diagnosed with Type-1 Diabetes. A descriptive correlational type of research was utilized to gather information on the level of awareness and compliance of adolescents patients to diet, exercise and drug management suffering from Type-1 diabetes mellitus. The patients (n=20) were recruited from Institute for Studies on Diabetes Foundation Incorporated, Philippines. A purposive sampling was utilized to select twenty adolescents. A researcher-made questionnaire was utilized as the main instrument in gathering data. Focus group discussion was also done to further assess patient's level of awareness and compliance to diabetes management. Results showed that patients have a moderate level of awareness and some extent of compliance to diabetes. Patients have extreme awareness in diet management and moderate awareness in exercise and drug management. In terms of compliance, patients are compliant to some extent only, while drug management has the highest highest level of compliance, followed by exercise and diet. There is a low correlation between level of awareness and compliance in diabetes management (r=.32 p=0.15), indicating that the moderate level of awareness of patients to DM management is not related to their compliance. The results are limited only to the participants of the study. Further study using a larger population and different setting is recommended. Nurses taking care of adolescent patients with diabetes mellitus must understand the importance of health education. Health educations are valuable to increase level of awareness and extent of compliance of adolescents patients with Type-1 diabetes.
