Abstract

Background and Objectives: The measurement of salivary immunoglobulin A is a useful and non-invasive method for measuring stress. Personality traits and rumination act as possible mediators in the relationship between psychological stressors and the immune system. This study was aimed to evaluate the levels of salivary IgA under psychological stress and its relationship with rumination and five personality traits in medical students. Methods: In this cross- sectional study, 45 medical students who intended to participate in the final exam were selected by simple random sampling. Two months before the exam, in the basal conditions, the NEO Personality Inventory-Short Form and Emotional Control Questionnaire (ECQ) were completed. Saliva samples were taken from students in both the basal conditions and exam stress conditions. Salivary IgA was measured by an ELISA test. Data was analyzed using paired samples T-test, Pearson correlation analysis, and stepwise regression. Results: A significant reduction of salivary IgA levels was found in exam stress conditions. Also, a significant negative correlation was found between traits of neuroticism and rumination with salivary IgA, as well as a significant positive correlation between of openness to experience and emotional inhibition with salivary IgA. Openness to experience and emotional inhibition may predict a substantial variance (34%) of salivary IgA under exam stress. Conclusions: Salivary IgA is reduced in response to exam stress. In addition, the rumination and personality traits may reduce or increase stress effects on the immune system, particularly the salivary IgA.

Abstract

Background: Metabolic syndrome (MetS) is the major risk factor for development of type 2 diabetes and cardiovascular diseases in different populations. The aim of this study was to evaluate the prevalence of MetS among Iranian population., Methods: Thirty-four cross-sectional studies were analyzed with a sample of 83227 people. National and international English electronic databases (PubMed, Google scholar, Web of Science, Science Direct, and Scopus) and Persian language databases (SID, Medlib, Iran medex, Magiran, Medlib, and IranDoc) were used to search the articles published on MetS in Iranian population from Jan 2005 to May 2016. The MetS diagnosis was performed according to the ATP-III, NCEP/ATP-III, IDF and WHO criteria., Results: The overall weighted prevalence of MetS was 31% (95% CI: 28-35). According to ATP III criteria, total and gender-stratified prevalence of MetS in women and men were 29% (95% CI: 22-36), 37% (95% CI: 26-48) and 29% (95% CI: 23-36), respectively. Total prevalence of MetS based on NCEP/ATP III criteria was 29% (95% CI: 24-35) that the prevalence was 24% (95% CI: 18-30) and 35% (95% CI: 25-44) in men and women, respectively. According to the IDF and WHO criteria, total prevalence of MetS were 38% (95% CI: 32-43) and 30% (95% CI: 7-53), respectively., Conclusion: The findings demonstrate an emerging high prevalence of MetS in total and in particular among Iranian women population. Therefore, to minimize the risk of cardiovascular events in Iranian population, screening and early detection of risk factors for MetS are required.
