Objective:
To investigate the changes of insulin resistance and islet beta cells function in subjects with euglycemia and high-normal blood pressure.
Methods:
Total 423 subjects were divided into normal blood pressure group and high-normal blood pressure group. Body height, weight, waist and hip circumference, and biochemical data were measured. Homeostasis model assessment of insulin resistance (HOMA-IR), insulin sensitivity index (ISI)-composite, and first-phase (1 PH) Stumvoll index were calculated. Results Waist circumference, total cholesterol, triglyceride, low-density lipoprotein cholesterol, HOMA-IR were significantly higher and IPH Stumvoll index and ISI-composite were significantly lower in high-normal blood pressure group than in normal blood pressure group (P < 0.05). Systolic blood pressure (SBP) was positively correlated with HOMA-IR (r = 0.122) and negatively correlated with 1PH Stumvoll index (r = -0. 159) and ISI-composite (r = -0.131) (P < 0.05). SBP and triglyceride were independent factors for IPH Stumvoll index.
Conclusion:
Insulin resistance and islet dysfunction may exist in subjects with high-normal blood pressure.

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 the...
