[Prevalence and risk factors for dyslipidemia in diabetics with overweight or obesity].

OBJECTIVE: To explore the prevalence and risk factors for dyslipidemia in diabetics with overweight or obesity. METHODS: Diabetics with overweight or obesity were recruited from 62 tertiary and secondary hospitals in Guangdong Province between August 2011 and March 2012. Dyslipidemia was diagnosed as total cholesterol (TC) ≥ 5.7 mmol/L or triglycerides (TG) ≥ 1.7 mmol/L or low-density-lipoprotein cholesterol (LDL-C) ≥ 3.6 mmol/L or high-density-lipoprotein cholesterol (HDL-C) < 1.29 mmol/L in females or HDL-C < 1.03 mmol/L in males. Binary Logistic regression was used to assess the associations between dyslipidemia and associated risk factors. RESULTS: Dyslipidemia was detected in 3160/3593 (87.9%) diabetics with overweight or obesity. And the prevalence of hypertriglyceridemia, low blood HDL-C, hypercholesterolemia and high blood LDL-C was 52.5% (1888/3593) , 54.1% (1945/3593), 33.1% (1188/3593) and 27.4% (985/3593) respectively. Among those with dyslipidemia, patients with simple and mixed dyslipidemia accounted for 34.1% and 53.9% respectively. In binary Logistic regression analysis, the presence of dyslipidemia were associated with female gender (OR = 1.593, 95%CI 1.233-2.057), hemoglobinA1c(HbA1c) (OR = 1.120, 95%CI 1.054-1.191), body mass index (OR = 1.084, 95%CI 1.022-1.150), hypertension (OR = 1.331, 95%CI 1.033-1.714), history of diabetes (OR = 1.586, 95%CI 1.186-2.120) and hyperuricacidemia (OR = 2.270, 95%CI 1.642-3.138). CONCLUSIONS: The prevalence of dyslipidemia is quite high in diabetics with overweight or obesity. The controls of blood pressure, serum uric acid level, blood glucose and body weight may reduce the prevalence of dyslipidemia, prevent and delay the development of cardiovascular complications and reduce the mortality of diabetics with overweight or obesity.

[A cross-sectional survey of blood pressure control in overweight or obese type 2 diabetic patients in Guangdong province].

OBJECTIVE: To investigate the current situation and influential factors of blood pressure (BP) control in type 2 diabetic patients with overweight or obesity in Guangdong province. METHODS: From August 2011 to March 2012, type 2 diabetic patients with overweight or obesity were recruited from 60 hospitals in 20 cities of Guangdong province, and received standard questionnaires. The conditions of demographic data, clinical examinations, the most recent laboratory assessment, history of disease and drug therapy were recorded. RESULTS: A total of 4029 patients were collected with age of (58.9 ± 12.9) years, and body mass index (BMI) of (27.28 ± 2.76) kg/m². Among the participants, controlled BP was achieved in 23.8% patients. Multiple logistic regression analysis showed that older age, obesity, previous history of hypertension and inadequate glycemic control were the independent factors related to unsatisfactory blood pressure control rate. Among the patients with hypertension, 53.5% took 1 kind of antihypertensive drug, 32.5% took two, and 11.3% took three or more. CONCLUSIONS: Type 2 diabetic patients with overweight or obesity in Guangdong province have poor BP control. Thus, active lifestyle interventions and drug therapy as a comprehensive management way should be taken for the population so as to reduce their cardiovascular events.

[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 HbA1c level was used to assess glycemic control. HbA1c < 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/m(2) and median waist circumference 93.0 (88.0 - 100.0) cm. Median HbA1c 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 cholesterol/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.
