Management status and its predictive factors in patients with type 2 diabetes in China: A Nationwide Multicenter Study

Background The prevalence of type 2 diabetes in China is increasing rapidly. Appropriate management of glycemia, blood pressure and dyslipidemia in this population is a major public health concern. Objective The aim of this study was to assess metabolic control including glycated hemoglobin A 1c (HbA 1c ), blood pressure (BP) and low density lipoprotein cholesterol (LDL‐c), in a large sample of patients with type 2 diabetes in China and to identify factors that correlated with the achievement of HbA1c, BP and LDL‐c goals (ABCs). Method A nationwide survey was conducted in 50 medical centres across China from April to July of 2010. Baseline information on demographics, medical history, HbA 1c , BP and LDL‐c levels were measured in 5961 patients with type 2 diabetes. Results Mean age, body mass index (BMI) and HbA 1c were 59.5 ± 1.3 years, 24.5 ± 4.1 kg/m 2 and 8.3 ± 2.2%, respectively. With respect to generally accepted ABC treatment goals, 35.2% of participants had HbA 1c <7%; 35.5% had BP < 140/80 mmHg, and 45.1% had LDL‐c < 100 mg/dl. The proportion of patients who met all three targets was only 5.4%. Logistic regression revealed that smoking ( P =0.000), higher BMI ( P =0.001) and insulin use ( P =0.000) were statistically significant predictors of failing to meet ABC targets. Conclusion The percentage of Chinese patients with type 2 diabetes who met recommended targets for HbA 1c , BP and LDL‐c in 2010 was low. Smoking, higher BMI and insulin use were the strongest determinants of failing to meet ABC targets. Copyright © 2015 John Wiley & Sons, Ltd.
