ObjectiveThe purpose of this study is to establish demographic and clinical data associated with the knowledge on diabetes management and its influence on glycemic control in patients with type 1 diabetes.MethodsThis was a retrospective, observational, multicenter study conducted with 1,760 patients between August 2011 and August 2014 in 10 cities of Brazil.ResultsOverall, 1,190 (67.6%) patients knew what glycated hemoglobin (HbA1c) means. These patients were older, had longer disease duration, longer follow-up in each center, reported lower frequency of self-reported hypoglycemia, and were more frequently Caucasians and at glycemic goal. Multivariate analysis showed that knowledge on what HbA1c means was related to more years of school attendance, self-reported ethnicity (Caucasians), severe hypoglycemia, economic status, follow-up time in each center, and participation on diabetes educational programs. Good glycemic control was related to older age, more years of school attendance, higher frequency of daily self-monitoring of blood glucose, higher adherence to diet, and knowledge on what HbA1c means.ConclusionPatients with a knowledge on what HbA1c means had a better chance of reaching an adequate glycemic control that was not found in the majority of our patients. Diabetes care teams should rethink the approaches to patients and change them to more proactive schedules, reinforcing education, patients' skills, and empowerment to have positive attitudes toward reaching and maintaining a better glycemic control. Finally, the glucocentric approach to diabetes management should be changed to actions that include patients' psychosocial aspects aiming to reduce the stress of living with diabetes, improving glycemic control, and avoiding adverse outcomes.
