Effect of Gender and Body Weight on Postprandial Glucose and Lipid Metabolism in Adults with Type 2 Diabetes

Abstract

Introduction: The magnitude of the healthcare problem of type-2-diabetes increases according to its association with several risk factors for cardiovascular diseases such as obesity and dyslipidemia. Methods: This study took place in the north-western region of Algeria. We aimed to assess the effect of body weight and gender on postprandial lipid and glucose in type-2-diabetes patients. 93 diabetic patients (age 55.65±13.81 years) were studied. Anthropometric parameters and body mass index (BMI) were measured. Fasting and postprandial (PP) glucose and lipid (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, apo A-I and apo B) profiles were evaluated. Results: There were a positive correlation between postprandial glucose and BMI in women (r2 = 0.041). Negative correlation with BMI was noticed for PP TG in both males (r2 = 0.011) and females (r2 = 0.021). A significant difference (p= 0.019) was observed for PP HDL-c in women (0.39 ± 0.10 g/L vs. men 0.33 ± 0.12 g/L) and also for PP apo A-I (women: 1.33 ± 0.27 g/L vs. men: 1.09 ± 0.34 g/L; p= 0.0003). According to gender and weight groups, our results indicated that female gender and overweight are associated with elevated PP HDL-c and PP apo A-I levels. However, obesity in women is related to high concentration of PP TG. Conclusions: The present study suggests that gender difference and weight classes are important factors that contribute to determining the postprandial responses, both for glucose and lipids, in type 2 diabetic patients.
