The aim of this study was to describe the glycaemic and metabolic control and diabetes-related complications in type 1 and type 2 Asian patients. Methods: Data of diabetes patients from 230 diabetes centres in 12 Asian regions were collected on a retrospective-prospective basis through review of medical records, interview and laboratory assessments. Analysis of glycated haemoglobin (HbA 1c ) was carried out in central laboratories appointed by Bio-Rad. The data collection case record forms were scanned electronically. Results: 22 177 patients with valid data made up the analysis population. Among patients with type 1 and type 2 diabetes, there was a higher proportion of women than men (53% vs. 47% for type 1 patients and 56% vs. 44% for type 2 diabetes). Hypertension (61%) and overweight (40% with BMI≥25 kg/m 2 ) were common in type 2 patients. Dyslipidaemia was also present in at least half of both types of patients. Control of glycaemia (mean HbA 1c and fasting blood glucose [FBG]) was poor in type 1 (9.9 ± 2.5%; 10.2 ± 5.2 mmol/l) and type 2 patients (8.5 ± 2.0%; 8.9 ± 3.4 mmol/l). Glycaemia in the majority of both types of patients fell short of those stipulated by various guidelines. In type 2 patients, glycaemia deteriorated (HbA 1c > 7.5%, FBG ≥ 7.0 mmol/l) with duration of diabetes > 7 years. Both types of diabetes appear to share a similar high prevalence of complications of cataract, retinopathy and neuropathy, although the prevalence of cataract (27%) and neuropathy (35%) was higher in type 2 diabetes. Screening for microalbuminuria was not common. Conclusions: The inadequate metabolic and hypertension control, especially in type 2 patients, needs to be addressed.
