Background and aim: Abnormalities in lipid metabolism are commonly observed in patients who were obese. Alongside dyslipidemia, one of the markers in predicting the risk of cardiovascular disease is the Atherogenic Index of Plasma (AIP), which is related to dietary intake. Healthy fat quality indices, including Atherogenicity (AI) and Thrombogenicity (TI) hypo/hypercholesterolemic ratio (h/H), the Cholesterol-Saturated Fat Index (CSI) and ω-3/ω-6 ratio might have an effect on AIP. The purpose of this study is to find the possible relationship between dietary fat quality, and AIP and comparison of these indices among obese and non-obese volunteers.Methods: This study was a cross-sectional descriptive-analytic case-control study with 157 normal and overweight and obese volunteers (n=71 normal vs n=86 overweight and obese) in the age range of 18-65 years. Food intake, anthropometric indices, body composition, and lipid profile were measured. Results: Based on the present results, comparable biochemical parameters including TC (P=0.580), TG (P=0.362) and LDL (P=0.687) and HDL (P=0.151) among overweight/obese volunteers as compared to normal ones were noticed. Results of dietary fat quality, including Atherogenicity (AI) and Thrombogenicity (TI) hypo/hypercholesterolemic ratio (h/H), the Cholesterol-Saturated Fat Index (CSI) showed significantly higher AI (P=0.012) in the overweight/obese group as compared to the normal group. Whereas, h/H (P=0.034) and ω-6/ω-3 ratio (P=0.004) were significantly higher in normal weight volunteers. There was a positive correlation between AI, TI, CSI, SFA, MUFA, PUFA and ω-6/ω-3 ratio with AIP and negative correlation between h/H with AIP in both groups. Despite significancies of these corelations no strong relation was observed by doing multiple regression among normal and overweight/obese groups (R2=0.210, R2=0.387).Conclusions: In summary, the present study suggest a direct relationship between dietary fat quality, increased BMI, and lipid abnormalities with AIP. However, further large-scale studies are needed to have a clear conclusion in this regard.

Food intake was measured using FFQ, anthropometric indices (weight, height, body mass index and waist to hip ratio), body composition (visceral fat level, total body water, body fat mass), and lipid profile were measured.

Background: Obesity is an important preventable disease, which promotes the development of chronic disorders by altering several factors including oxidative stress. Dietary antioxidants protect the body against oxidative stress. The purpose of this study was to evaluate the potential association of oxygen radical absorbance capacity (ORAC) index with obesity and its associated features in adults.Methods: participants were divided in two groups of normal weight and overweight /obesity. General characteristics were registered and a 147-item food frequency questionnaire was completed. Thereafter, anthropometric measurements were conducted. Biochemical indices were obtained from science and Research branch of Islamic Azad University of Tehran, Iran. The amount of the dietary ORAC index was estimated using the data provided by the USDA Foods Table.Results: The results showed that there was a significant difference between the normal and overweight/obese groups in terms of body mass index (BMI) and waist-to-hip ratio (WHR) (P=0.0001). Participants with normal weight consumed more fruits and vegetables than another group. Also, the dietary ORAC index in normal individuals was higher than the case group, but there was not significant difference (P=0.352). There was also a significant inverse correlation between dietary ORAC and BMI and WHR, whereas a significant positive correlation between dietary ORAC and plasma HDL was observed (P<0.05).Conclusion: Our findings suggest that dietary antioxidants is inversely associated with BMI, fasting blood glucose, triglyceride, total Cholesterol and LDL in both groups. It seems that following a diet rich in antioxidants can counteract obesity and its associated comorbidities.
