Objectives:
To compare ankle brachial pressure index (ABPI) in normal weight and obese/overweight type 2 diabetes mellitus patients (T2DM) to see the impact of obesity on the occurrence of peripheral artery disease (PAD) in T2DM patients. Secondly to investigate the relationship between ABPI, insulin resistance, and beta cell function and between adipocytokines and obesity parameters.
Methods:
A total of 120 BMI-categorized Normal weight (NW) T2DM (n = 53) patients and obese/overweight T2DM (n = 67) patients were recruited in this study. ABPI measurements were performed for the assessment of PAD. The anthropometry and body composition of the patients were measured. Plasma fasting insulin, adiponectin, and IL-6 levels were measured by ELISA kits.
Results:
ABPI scores were found to be comparable between both groups of patients (p = 0.787). A significant positive correlation was observed between ABPI and beta cell function. Insulin resistance was found to correlate positively while adiponectin negatively with obesity parameters.
Conclusion:
The ABPI score was comparable between both groups of patients, suggesting that vascular complications may occur at the same rate in NW as well as in obese/overweight diabetic patients. The positive association of insulin resistance as well as the negative association of adiponectin with obesity parameters, are suggestive of the importance of body fat distribution in predicting insulin resistance and the inflammatory status of the cells.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
