Aims: Several health benefits are contributed to extra virgin olive oil (EVOO). The polyphenol fraction of EVOO may be responsible for its cardioprotective impacts. This systematic review and meta-analysis aimed to investigate the effect of EVOO intake on glycemic parameters. Electronic literature searched through 1 September 2020 across MEDLINE/PubMed, Web of Science, and SCOPUS databases to find all clinical trials that reported the effect of EVOO intake on glycemic parameters [FBS(fasting blood glucose), insulin, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) and HbA1c (glycated hemoglobin A1c)] vs. control.

Data Synthesis: We pooled standardized mean differences (SMD) and 95% confidence intervals (CIs) from randomized clinical trials (RCTs) using random-effects models. Heterogeneity was assessed by Cochran Q-statistic and quantified (I). We found 13 related trials comprising a total of 633 subjects. In pooled analysis, EVOO intake had no effect on FBS (SMD: -0.07; 95% CI: -0.20, 0.07; I = 0.0%), insulin (SMD: -0.32; 95% CI: -0.70, 0.06; I = 38.0%), and HOMA-IR (SMD: -0.32; 95% CI: -0.75, 0.10; I = 51.0%). However, a decreasing trend was observed in these effects. Subgroup analysis based on age, health status, dose, and EVOO intake duration also did not significantly change results.

Conclusion: Although EVOO seems a promising hypoglycemic effects, we did not find any significant evidence that EVOO consumption impacts glucose homeostasis. Furthermore, well-designed RCTs with longer durations are still needed to evaluate the EVOO's efficacy on glycemic parameters.

Eating disorders risk and its relation to self-esteem and body image in Iranian university students of medical sciences.

Eat Weight Disord 2016 Dec 23;21(4):597-605. Epub 2016 Apr 23.

Introduction And Objectives: Eating disorders are rapidly increasing in young adults. But, a few studies have examined the risk of eating disorders and body image in university students of non-Western societies. The current study aimed to assess eating disorders risk in relation to body image and self-esteem among Iranian university students.

Method: The participants were 430 students from Tabriz, between April and May 2015. The 26-item Eating Attitude Test (EAT-26), Multidimensional Body-Self Relations Questionnaire (MBSRQ) and Rosenberg's Self-Esteem Questionnaires were used. EAT-26 score of 20 or more was considered as eating disorders risk cutoff.

Results: Majority of the students (68 %) were females. The overall eating disorders risk was 9.5 % (7.5 and 10.5 % in men and women, respectively). Further, the prevalence of poor body image and low self-esteem was 34.2 and 16 %, respectively. Neither of the gender differences was statistically significant (p > 0.05). In simple logistic regression, there were significant associations between self-esteem, body image, parental education and eating disorders risk (p < 0.025). But, after adjustments for gender, age, Body Mass Index (BMI) and marital status, only self-esteem (OR = 0.37, 95 % = 0.16-0.87) and mother's education level (OR = 2.78, 95 % = 1.30-5.93) were predictors of eating disorders risk.

Conclusions: The findings revealed that low self-esteem and mother's higher education may increase eating disorders risk and the predictive role of body image possibly is by other mediators such as self-esteem. This warrants awareness improvement and developing appropriate interventions targeting self-esteem and self-respect of students.

The Relationship of Disordered Eating Attitudes With Body Composition and Anthropometric Indices in Physical Education Students.

Iran Red Crescent Med J 2015 Nov 14;17(11):e20727. Epub 2015 Nov 14.

Department of Clinical Nutrition, School of Nutritional Sciences and Dietetics, Tehran University of Medical Sciences, Tehran, IR Iran.

Background: Abnormal eating behavior, unhealthy weight control methods, and eating disordered symptoms have risen among college students.

Objectives: The aim of this study was to examine disordered eating attitudes and their relationship with anthropometric and body composition indices in physical education students in Tabriz, the capital of East Azerbaijan province, Iran.

Patients And Methods: This cross-sectional study was conducted on 210 physical education students, 105 males and 105 females aged 18 to 25, who were selected by systematic random sampling from physical education faculty of Tabriz University in Tabriz, Iran, in 2013. Eating attitude test (EAT-26) was used for the assessment of disordered eating attitudes. In addition, anthropometric and body composition indices were assessed.

Results: About 10% of the studied subject had disturbed eating attitudes; significantly more males (15.4%) reported an EAT-26 ≥ 20 (disordered eating attitudes) than females (4.8%) (P < 0.05). In males, the EAT-26 score was positively correlated with weist perimeter (WP) (r = 0.21, P < 0.05) and the waist-to-hip ratio (r = 0.26, P < 0.01). In females, the EAT-26 score was positively correlated with weight (r = 0.19, P < 0.05) and the WP (r = 0.28, P < 0.01). In females, weight (P < 0.05), body mass index (BMI) (P < 0.05), WP (P < 0.01), and waist-to-hip ratio (P < 0.05) were significantly different between disordered eating attitude and healthy subjects, while in males there was no significant difference between the two groups regarding the anthropometric and body composition indices.

Conclusions: Abnormal eating attitude was notable among physical education students in Tabriz, Iran. It seems that some anthropometric indices such as BMI and central obesity indices were related to the increase of disordered eating attitude.
