Prevalence, awareness, treatment, and control of hypertension in patients with type 2 diabetes: A cross-sectional survey among middle-aged people in China

Abstract

Objective: To assess the prevalence, awareness, treatment, and control of hypertension and their associated factors in patients with type 2 diabetes. Methods: A cross-sectional survey across China, including 12,000 participants aged 35-64 years, was conducted in 2009-2010. Data were collected by using questionnaires, blood pressure (BP) measurement, and laboratory test. About 11,623 participants fitted the inclusion. Diabetes was defined as fasting glucose at least 7.0 mmol/L, and/or use of insulin, and/or oral antidiabetic drug. For diabetic participants, hypertension was considered to be controlled if the average BP was <130/80 mmHg. Results: Overall, there were 1063 patients with diabetes (9.2%). The prevalence of hypertension among the patients with diabetes was 59.6%. Among the hypertensive patients (n = 633), 57.5% were aware of their condition, 41.7% received treatment, and only 3.8% had their BP adequately controlled. Age, region, body mass index (BMI), and family hypertension history were correlated with the prevalence, awareness, treatment, and control of hypertension among patients with diabetes. Conclusion: The prevalence of hypertension among patients with diabetes was higher whereas the control was lower. Age, BMI, and family hypertension history were significantly associated with hypertension.
