Relationship between Body Composition and Energy and Macronutrient Intake with Oxidized Low-Density Lipoprotein among Middle-Aged Men

Abstract
It has been shown that obesity is associated with increased rates of dyslipidemia. High-fat intake and high adiposity contribute to dyslipidemia. The present work was aimed to determine the significance of various indicators of obesity such as anthropometric variables as well as intakes of energy and macronutrients in the clinical assessment of type and severity of dyslipidemia, especially oxidized LDL (ox-LDL). This cross-sectional study was performed on 75 men aged 30 to 55 years without diabetes, cardiovascular disease, high blood pressure, and any other malignancies. Weight, height, waist circumference, body fat percentage and lipid profile including ox-LDL were measured. The physical activity level and dietary intake of participants were assessed by standard questionnaires. Participants were divided into two groups; obese and non-obese individuals. In the group with obesity (N = 26), the mean serum levels of ox-LDL and HDL-C were indicated to be significantly higher and lower respectively, compared to individuals without obesity. There was a significant positive correlation between the percentage of calories from fat and ox-LDL level (B = 0.24, P <0.05), and a significant negative correlation between the percentage of calories from carbohydrate and ox-LDL level (B = -0.29, and P <0.05). Moreover, there was a significantly negative correlation between serum levels of HDL-C and the percentage of calories from fat (B = -0.20, and P <0.05).
