Analysis on the status and influencing factors of glycemic control in type 2 diabetic patients with hypertension in urban areas of Huai'an

Abstract

Objective To explore the clinical features of type 2 diabetic patients with hypertension , and to analyze the influencing factors of glycemic control. Methods Using stratified cluster random sampling method, 5 communities were selected from urban areas of Huai'an in 2014. Type 2 diabetic patients managed by the communities were surveyed with questionnaire, physical and biochemical examinations. The related information and clinical features were compared between diabetic patients with and without hypertension. Logistic regression analysis was used to analyze the influencing factors of glycemic control. Results The number of well-controlled diabetic patients (HbA1c<7.0%) with and without hypertension (HbA1c<7.0%) were 419 (39.3%) and 480 (52.1%), respectively. Mean values of body mass index (BMI), diabetic duration and serum creatinine in diabetic patients with hypertension were significantly higher than those in diabetic patients without hypertension (P<0.05). The proportions of macrovascular complications and dyslipidemia in diabetic patients with hypertension were significantly higher than diabetic patients without hypertension (P<0.05). Multiple logistic regression analysis showed that high degree of education, high annual family income and high frequency of glucose monitoring were beneficial factors for glycemic control in diabetic patients with hypertension. Older age, hypertension, higher waist to hip ratio (WHR), the elevated triglyceride and serum creatinine were harmful factors for glycemic control. Conclusions The situation of glycemic control in diabetic patients with hypertension in urban areas of Huai'an is not optimistic. Therefore, community managements of risk factors such as central obesity and increased triglyceride in elder diabetic patients should be strengthened.
