Abstract: Objectives: To describe the clinical profile of Brazilian patients with type 2 diabetes attending the public healthcare system and identify factors associated with poor glycaemic control.Design: Cross-sectional study.Setting: 14 centres in five regions of Brazil, including primary care units and outpatient clinics of University Hospitals.Participants: Patients with type 2 diabetes attending outpatient clinics of public healthcare system.Main outcome measured: Glycated haemoglobin (HbA1c), centrally measured by high-performance liquid chromatography (National Glycohemoglobin Standardization Program certified).Results: A total of 5750 patients aged 61 10 years, with 11 8 years of diabetes duration (66% women, 56% nonwhite, body mass index: 28.0 5.3 kg/m(2)) were analysed. Mean HbA1c was 8.6 +/- 2.2%, and median HbA1c was 8.1% (6.9% to 9.9%). HbA1c <7% was observed in only 26% of patients. Mean HbA1c was higher (p <0.01) in the North (9.0 +/- 2.6%) and Northeast (8.9 +/- 2.4%) than in the Midwest (8.1 +/- 2%), Southeast (8.4 +/- 2.1%) and South regions (8.3 +/- 1.9%). Using the cut-off value of HbA1c above the median, age (0.986 (0.983 to 0.989)), white ethnicity (0.931 (0.883 to 0.981)) and being from Midwest region (0.858 (0.745 to 0.989)) were protective factors, while diabetes duration (1.015 (1.012 to 1.018)), use of insulin (1.710 (1.624 to 1.802)) and living in the Northeast region (1.197 (1.085 to 1.321)) were associated with HbA1c >8%.Conclusions: the majority of Brazilian patients with type 2 diabetes attending the public healthcare system had HbA1c levels above recommended targets. the recognition of Northeast residents and non-white patients as vulnerable populations should guide future policies and actions to prevent and control diabetes.
