Introduction: Blood pressure among youth is associated with increased risk of future cardiovascular disease occurrence. The studies done on hypertension prevalence among young population are still insufficient. The purpose of this study was to determine undiagnosed hypertension, based on the Seventh Report of the Joint National Committee (JNC7) on Prevention, Detection, Evaluation and Treatment of High Blood Pressure updated guidelines among the apparently healthy young group of Iranian population. Methods: In this cross-sectional study, 901 volunteers, without previous hypertension history, in the age group of 18-24 years old (body mass index< 40 kg/m2) were assessed in Ardabil city from September 2016 to March 2008.They were apparently healthy youth and reported that their body weight had been stable for at least the last 3 months. Blood pressure was measured by standardized protocols based on American Heart Association guidelines, and the final value was obtained using the mean of the two careful readings of office blood pressure monitoring. Data were analyzed using Statistical Package for Social Sciences version 21.0. One-way analysis of variance was applied to determine the differences among hypertension groups, and p values <0.05 were considered statistically significant. Results: The mean of age, weight and body mass index was 19.48±1.64 (years), 60.54±11.45 (kg) and 21.39±3.17 (kg/m2), respectively. According to the JNC7 updated guidelines (2017), 17.4% subjects fell into elevated blood pressure whereas 2.1% and 1.7% into stage I and II hypertension category, respectively. Males were significantly more likely to have elevated blood pressure and stage I and stage II hypertension than females (p<0.001). Conclusion: According to the JNC7 updated guidelines, there is a significant prevalence of undiagnosed elevated blood pressure and hypertension (21.1%) among Iranian youth population. These results emphasize the need for careful monitoring of the blood pressure even among apparently healthy young adults

Introduction: Research results show that unmanaged use of virtual networks is the cause of differences between couples. Accordingly, the present study aimed to determine the mediating role of attitudes toward betrayal and marital conflicts in the relationship between the use of virtual social networks and emotional divorce in married teachers in Mashhad. Methods: The research method was descriptive-correlational and the society included married teachers in seven areas of education in Mashhad city in the academic year of 2017-2018. 375 teachers were selected by quota sampling method and completed questionnaires on social networks, emotional divorce, attitudes toward betrayal and marital conflicts. Data were analyzed using path analysis using Maximum Field Definition (ML). The structural equation modeling was used to analyze data using AMOS software version 25. Results: Based on the findings, the mediating role of attitude toward betrayal was not significant for predicting emotional divorce based on the use of virtual social networks (β = 0.06).The role of conflicting intermediaries is significant for predicting emotional divorce based on the use of virtual social networks. Accordingly, the role of the mediating meanings of marital conflicts along with the non-perceptible role of attitudes toward betrayal, based on the use of virtual social networks, predicts a total of 20% of the variance of emotional divorce. If the direct role of using virtual social networks in predicting emotional divorce along with the role of intermediate variables is considered, 66% of the variance of emotional divorce is predictable. Fit indicators showed the optimal fitness of the model with the collected data. (P <0.05) Conclusion: The results of this study showed that increasing the use of virtual networks with increasing conflicts increases the incidence of emotional divorce in couples.

Introduction: An unhealthy breakfast and the consumption of low-value meals among students are associated with adverse health consequences and chronic diseases in adulthood. The main purpose of this study was to identify the determinants of preparing healthy breakfast and snacks for school children by mothers in the city of Islamshahr. Methods: 320 boys and girls were selected by cluster random sampling and their mothers were invited to participate in the study. Data were collected using the researcher-made questionnaire that included demographic characteristics, questions were related to knowledge, attitude, perceived benefits, perceived barriers and behavior. The reliability was assessed through the test-retest method, and in order to assess internal consistency, Chronbach’s alpha coefficient was used. Data were analyzed by SPSS 16 software, and Descriptive statistics (Percent & Frequency), Multiple regression and Kendall’s tau-b correlation tests were used. Results: Based on the findings of this study, none of the demographic characteristics had a significant correlation with the behavior of the mother's healthy breakfast and meal (p>0.05) and among variables, knowledge (p<0.001, B=0.40) and perceived barriers (p<0.001, B=0.33) were strong and positive predictors of preparing breakfast and healthy snacks by mothers. Knowledge and perceived barriers predict %28 of variance in mothers’ behavior in preparing breakfast and healthy snacks (p<0.001, R= 0.527, R2=0.278). Conclusion: It is better to put more emphasis on the strategies to promote the knowledge of mothers and reduce their perceived barriers in designing nutritional interventions aiming to prepare breakfast and healthy snacks for children.
