Objective To investigate correlation of abdominal adipose tissue distribution and insulin resistance in T2 DM. Methods A total of 128T2 DM patients were divided into two groups：obese（OG）group（n=66）and non-obese（NOG）group（n=62）.Spiral CT was used for the measurement of adipose tissue of the total area（TA）and visceral fat area（VA）at abdominal umbilical level lumbar vertebrae 4,5plane in T2 DM patients.Subcutaneous fat area（SA） was calculated.General and biochemical characteristics were measured in both groups.

Conclusion Abdominal fat distribution is closely related to IR in T2 DM patients.
