Nationwide Assessment of Cardiovascular Risk Factors: in Chinese Patients With Type 2 Diabetes
The objective of this study is to evaluate the level of control of cardiovascular disease risk factors, including blood pressure, blood lipid, and blood glucose, in out patients with type 2 DM in 6 representative regions in China: Northeast, North, East, South, Southwest and Northwest, measured by,
1. Proportion of patients reaching adequate control of blood glucose
2. Proportion of patients reaching adequate control of blood glucose and blood pressure, or blood glucose and blood lipid
3. Proportion of patients reaching adequate control of all 3Bs, i.e. blood glucose, blood pressure, and blood lipid.
The prevalence of patients with diabetes mellitus (DM) worldwide has increased from 30 million in 1985 to 180 million at the present time. In China, the incidence of overweight, obesity, and DM has increased rapidly due to the significant change of diet and lifestyle resulted from rapid economic development. As estimated by International Diabetes Federation (IDF), the number of the patients with DM was about 39.8 million in China in 2007, and it is anticipated that the number would reach 59.3 million in 2025 . At the same time there are a similar number of pre-diabetes patients with risk factors of cardiovascular diseases in China. DM and its associated microvascular and macrovascular complications could severely affects patients' quality of life and duration of survival and lead to significant increase in medical expenditure.
There have been a number of epidemiological surveys of diabetes conducted in other countries. However, there is little specific data available on the status of DM control and clinical outcomes of prevention and treatment of diabetic cardiovascular complications and other microvascular complications in China. This has made it difficult for clinicians to effectively make medical choices for patients with a variety of risk factors and complications.
This study is thus designed to assess the level of control of CVD risk factors, including blood pressure, blood lipid, and blood glucose, in outpatients with type 2 DM nation-wide across 6 representative regions in China: Northeast, North, East, South, Southwest and Northwest. The difference in clinical outcomes between the regions and between the three different tiers of hospitals, i.e. tier 3 (primary or teaching hospitals), tier 2 (secondary or city level hospitals), and tier 1 (community hospitals/health centers), will be made. The primary measurements include 1)Proportion of patients reaching adequate control of blood glucose (1B); 2)Proportion of patients reaching adequate control of blood glucose and blood pressure, or blood glucose and blood lipid (2B); and 3)Proportion of patients reaching adequate control of all 3Bs, i.e. blood glucose, blood pressure, and blood lipid. Other measurements include proportion of microvascular and macrovascular diabetic complications, DM treatment pattern and influence factors, physician prescribing behaviors, etc.

Medical and Biotech [MESH] Definitions
The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).
Diabetes Mellitus, Type 2
A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
Hyperlipoproteinemia Type V
A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .
Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
Diabetes Mellitus, Type 1
A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
