Methods Subjects having registered for care for > 12 months at a diabetes clinic were enrolled in this study. Glycaemic control was determined by HbA1c and plasma glucose levels; information about self-reported adherence to treatments was obtained by questionnaire; psychological well-being was assessed by use of a modified World Health Organization-5 Well-being Index; and quality of life was measured by use of a modified Diabetes Attitudes, Wishes and Needs (DAWN) survey. All data were tabulated and statistical analyses were performed.
Results A total of 2702 patients were enrolled during 2006. Only 23% of patients achieved an HbA1c level of < 48 mmol/mol (6.5%) as per the 2007 China guideline for Type 2 diabetes and only 16.2% followed all treatment recommendations from healthcare providers. Of the patients, 46.0-68.6% of the patients showed positive psychological well-being. A quality-of-life survey showed that 28.5-50.6% of the patients experienced various diabetes-related emotional problems. Large percentages (approximately 50%) of patients were experiencing psychological insulin resistance.
Conclusions Although in China therapies for Type 2 diabetes are more effective and available than ever before, the patient outcomes remain disappointing. Problems with glycaemic control, self-reported adherence to treatments, psychological well-being and quality of life, all of which are key to diabetes control, are common among Chinese patients with Type 2 diabetes.
