Background The coronavirus 2019 (COVID-19) pandemic requires integrated intervention by both the governments and individuals. University students have a great role in distributing reliable information about disease prevention behaviors. The aim of this study was to identify the Knowledge, Attitude and Practice of COVID-19 Prevention and Self-Protection behaviors in students. Methods This cross-sectional online survey was conducted on Iranian university students. All students filled a questionnaire consisting of demographic characteristics, e-Health Literacy Scale (EHEALS) questionnaire and a researcher-made knowledge, attitude and practice (KAP) questionnaire. Data was analyzed using the SPSS software. Results A total of 925 students (69.9% female) participated in this study. The median age of the students was 23 years old. Majority of students (641, 69.3%) were non-medical students. The median and interquartile range (IQR) for knowledge, attitude, practice and P-EHEALS scores in Medical students were 52.00 (27.00), 4.00 (1.00), 28.00 (8.00), and 26.00 (9.00), respectively which were significantly higher than non-medical students, 28.00 (15.00), 3.00 (2.00), 20.00 (8.00), and 26.00 (9.00), respectively (p < 0.001). Practice score was a significant related to knowledge (p < 0.001), attitude (p < 0.001), having a COVID-19 infected family member (p < 0.001), older age (p < 0.001), medical field of education (p = 0.001), higher EHEALS score (p = 0.018), and female gender (p = 0.013). Knowledge, attitude and having a COVID-19 infected person in family were the strongest predictors of preventive practices. Conclusions KAP and E-Health literacy of university students, especially non-medical students, should be considered in order to improve COVID-19 preventive behaviors in the society.

Background and Aim: Preeclampsia is the third leading cause of maternal mortality in the world and the second most common cause of death in pregnant mothers in Iran. Psychosocial aspects have been recently considered as a risk factor for developing preeclampsia. The purpose of this study was to determine the association between psychological factors and the chance of developing preeclampsia. Materials and Methods: This systematic review and meta-analysis was performed based on the studies conducted in the world. We searched seven databases )Irandoc, SID, Magiran, Iranmedex, PubMed, Scopus, Web of science, Cochrane, ISI, and Embace databases), by using keywords of psychological factors, stress, anxiety, depression, and preeclampsia to find relevant articles published between 2008-2018. Data from relevant studies were extracted by two persons separately and evaluated by using the Stroop checklist. After extracting the required data, they were combined using a random model and the heterogeneity of the studies was evaluated by the I2 indices. STATA-11 software was used for data analysis. Results: In the present study 11 articles were analyzed. The total number of samples in the study was 658678. The chances of preeclampsia in individuals with stress, anxiety, depression, and those exposed to violence were estimated to be 1.21, 3.07, 3.04, and 2.37, respectively. Conclusion: Considering the importance of preeclampsia in pregnancy and its impact on maternal and fetal health, basic measures should be taken to prevent it by identifying people at risk and the contributing factors, such as routine screening of psychological factors before and through the pregnancy semesters.

Context: Postpartum depression is a common condition, which is managed by antidepressants. Antidepressants are generally considered to be safe during breastfeeding, and the probability of exposure to antidepressants through breast milk is low to very low. Due to the beliefs of breastfeeding women that antidepressants may have side effects on infants, complementary and alternative medicine (CAM) is being investigated to play a role in the management of postpartum depression. Yoga is among the complementary therapies that showed preventive effects against depression in some age and disease groups. The aim of this systematic review was to assess the effects of Yoga intervention on healthy pregnant women and its preventive effects on postpartum depression. Methods: Clinical databases, including Scopus, PubMed, Medlib, Web of Science, Psych Info, and Cochrane Library, as well as Google Scholar, were searched using search keywords, including pregnant women, women, maternal period, yoga, mindfulness, postpartum depression, and depression. Clinical trial, case-control, and cohort articles in English language that assessed the effects of Yoga on postpartum depression in healthy women were reviewed. Among the initial 982 identified studies, five studies (271 subjects) were eligible for the review. Due to the high heterogeneity in the studies, meta-analysis was not performed. Results: One study had medium quality, one study had good quality, and three studies had high quality. Yoga intervention included physical and mindfulness exercises and assessed mood and behavior during pregnancy. The intervention duration ranged between 6 and 24 weeks during pregnancy. In the majority of studies, Yoga intervention reduced postpartum depression and other mental disorders. Conclusions: Yoga may be a beneficial and safe choice in the management of postpartum depression in healthy pregnant women.
