[A cross-sectional survey on current status of type 2 diabetes mellitus with overweight or obesity in Guangdong province].

Objective To explore the glycemic control status and related risk factors of overweight or obesity patients with type 2 diabetes mellitus (T2DM) in Guangdong province. Methods The medical records of overweight or obesity patients with T2DM from 60 tertiary and secondary hospitals in Guangdong Province were collected by questionnaire and physical examination.And the clinical data were analyzed to explore the influencing factors of glycemic control.The Hb A1c level was used to assess glycemic control.Hb A1c<7.0% indicated that glycemic control was up to standard. Results From August 2011 to March 2012,5241 T2DM patients were recruited.The scope of current analysis was restricted to 4768 subjects with true data and deficiency no more than 5%.There were 2252 males and 2516 females.The age range was from 16 to 90 years,a median age 59.0 (50.0-69.0) years,onset age of diabetes 52.0 (44.0-60.0) years:a range of disease duration from 1 day to 42 years and a median of 5.0 (2.0-11.0) years.The median body mass index was 26.33 (24.88-28.34) kg/m2and median waist circumference 93.0 (88.0-100.0) cm.Median Hb A1c was 8.1% (6.9%-10.1%) and only 26.2% patients reached the target level of HbA1c<7.0%.Influencing factors of poor glycemic control were central obesity,high levels of resting heart rate,concurrent fatty liver and high intensity of treatment.And influencing factors of good glycemic control were regular exercises,smoking cessation,regular glycemic monitoring and good control of total chloestrol/triglyceride. Conclusion A majority of Guangdong type 2 diabetics fail to achieve target values for glycemic control.There is an urgent need for comprehensive management for improving glycemic control.
