Influence of obesity and overweight on blood coagulation and metabolic indexes in patients with type 2 diabetes mellitus / 心血管康复医学杂志

ABSTRACT

Objective: To study influence of overweight and obesity on blood coagulation and metabolic disorders in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 248 preliminary diagnosed T2DM patients were selected. According to body mass index (BMI), they were divided into normal BMI control group (n=95), overweight group (n=87) and obesity group (n=66). Blood lipids, blood glucose and fasting insulin (FINS) were measured in all patients and homeostasis model-insulin resistance index (HOMA-IR) was calculated then. Statistical analysis was performed. Results: Compared with normal BMI control group, there were significant increase in fibrinogen [(3.37±0.55) g/L vs. (4.04±0.70) g/L vs. (5.20±0.69) g/L], urine microalbumin [(14.46±8.90) mg/g vs. (47.33±42.54) mg/g vs. (104.45±60.78) mg/g], fasting blood glucose [ (7.15±0.97) mmol/L vs. (8.84±1.81) mmol/L vs. (10.06±2.28) mmol/L], FINS [(10.09±8.21) IU/ml vs. (14.33±15.55) IU/ml vs. (19.69±10.86) IU/ml], HOMA-IR[(3.19±2.59) vs. (5.51±5.38) vs. (8.48±4.62)], TG, TC and LDL-C levels in overweight group and obesity group, and the more BMI patients were, the higher these indicators were; There were significant decrease in plasma prothrombin time [(13.33±0.69)s vs. (12.74±0.69)s vs. (11.43±0.53)s], activated partial thromboplastin time [ (37.32±2.31)s vs. (36.55±2.41)s vs. (34.61±1.53)s] and HDL-C [(1.54±1.12) mmol/L vs. (1.27±0.41) mmol/L vs. (1.09±0.28) mmol/L] in overweight group and obesity group（P<0.05 all）. Conclusions: Overweight and obesity aggravate coagulation and metabolic disorders in patients with type 2 diabetes mellitus. It also aggravates degree of insulin resistance, the more BMI patients are, the more serious they are.
