Physical activity and nutrition are important topics in adolescent health. This study aimed to determine the predictors of nutritional knowledge, behaviors, and physical activity in fifth-grade elementary school female students

This cross-sectional descriptive-analytical study was performed on 480 female students in the fifth grade of the elementary school in Gods city in 2020-2021 by cluster random sampling. Data were collected using a researcher-made questionnaire two-part questionnaire of contextual questions and questions about knowledge, nutritional and physical activity, virtual in the Shad messenger. The content validity ratio and content validity index was used to determine validity, and the intra-cluster correlation index to determine the reliability, of the questionnaire. In data analysis, descriptive statistical tests, Pearson         
correlation coefficient, and multiple regression analysis were performed using SPSS 27.

The results of multiple regression analysis showed the effect of nutritional knowledge variables on nutritional behavior (p <0.001, β = 0.159) and physical activity knowledge on nutritional behavior (p = 0.008, β = 0.120) if the Physical activity knowledge variable was not effective on physical activity behavior and also nutritional knowledge variable had no effect on physical activity behavior.

Increasing knowledge of nutrition and physical activity improves students' nutritional behavior, but this increase in knowledge does not affect physical activity behavior. The sedentary lifestyle and the presence of the Covid-19 pandemic appear to have significantly reduced physical activity. By increasing knowledge, nutritional behavior and physical activity can be improved to some extent

 Some people experience positive psychological changes in various aspects after a stressful event. These positive changes, known as Post-Traumatic Growth (PTG), are often due to people’s need to adapt to the challenges ahead.

 This study aims to determine the predictors of PTG in patients with myocardial infarction.

 This is a descriptive-correlational study. Participants were 191 patients with myocardial infarction referred to the cardiac clinic of Bu-Ali Sina Hospital in Qazvin, Iran. They were selected using a convenience sampling method and based on inclusion/exclusion criteria. The research instruments were the Post-Traumatic Growth Inventory (PTGI), Multidimensional Perceived Social Support Scale (MSPSS), and the Meaning in Life Questionnaire (MLQ). Collected data were analyzed in SPSS V. 25 software using Pearson correlation test and linear regression analysis.

 There was a significant positive relationship between PTG with perceived social support (r=0.47 and P<0.001) and meaning in life (r=0.71 and P<0.001). Based on the results of linear regression analysis, an increase in the scores of MSPSS and MLQ can increase the PTGI score by 0.978 and 1.376, respectively.

 This study provided important insights into the phenomenon of PTG in patients with myocardial infarction and its predictors, which can help improve PTG in them.

Metabolic syndrome is the result of a general imbalance of metabolic processes in the body which increases mortality due to cardiovascular disease. The syndrome has recently attracted the attention of health care researchers to its impact on quality of life. Rational differences and occupational diversity affect the prevalence of metabolic syndrome. The purpose of this study was to determine the prevalence of the disease among Gachsaran oil industry employees. The present paper was a descriptive cross-sectional study. During the years 2016-20173, 360 employees were randomly selected using a questionnaire, Alpikado pressure gauge, and Scala scale. Fasting blood samples were taken to measure triglyceride, glucose, LDL, HDL, and total cholesterol. Diagnosis was performed using NCEP ATP III criteria, with prevalence of less than 10, 10-25 and above 25% as low, moderate and high prevalence respectively. The collected data were analyzed using Chi-Square and logistic regression. The prevalence of metabolic syndrome in the whole sample was 30.3, 31.2 and 7.1%, respectively. Furthermore, the prevalence of abdominal obesity was 74.1%, thyroid triglyceride 46.6%, high systolic blood pressure 39, HDL cholesterol Low 33, fasting blood glucose was 13.3 and high diastolic pressure was 13%. A reduction in serum HDL cholesterol and one increase in waist circumference, systolic blood pressure, fasting blood glucose and triglyceride were associated with a 15, 14, 7, 4 and 1 percent increase the odds of contracting a disease , respectively. The prevalence of high metabolic syndrome was higher; in addition, the prevalence was higher in men than in women. This indicated the impact of gender differences and occupational situations on the prevalence of this metabolic disorder. Therefore, the necessity of paying more attention to specific occupations in periodic studies is recommended.

Pre-eclampsia and eclampsia is a common complication of pregnancy and considered as one of the three major causes of maternal mortality. There are multiple risk factors for etiology of this syndrome. Recently، season of conception and birth is taken into consideration. This study was done to determine the relationship between season of conception، birth and other predictors in women with eclampsia. This descriptive-analytical retrospective study was conducted on 623 pregnant women with pre-eclampsia and eclampsia who referred to Alzahra and Taleghani hospitals in Tabriz، Iran during 2007 to 2012. Data were collected using a questionnaire containing information about socio-demographic and information about conception and birth season. Data were analyzed using SPSS software version 17، descriptive statistics and logistic regression tests. P value less than 0. 05 was considered significant. Age and parity were estimated to be as independent predictor of eclampsia. There was a significant association between pre-eclampsia and season of conception (p<0. 01). The risk of eclampsia in the spring was 5 times more than autumn (OR=4. 87، 95%، CI=1. 94 to 12. 20). There was no significant association between eclampsia and season of birth (p=0. 13). There is a significant association between eclampsia and season of conception

Although there are many risk stratification models, but there is no widely applicable method for readily determining outcomes preoperatively. The main aim of this study was to identify the predictors of cardiac surgery morbidities. In a three- months period a prospective observational cohort study was conducted among 130 consecutive patients, who were admitted to the cardiac surgery ICU. Many variables were collected by data collecting sheets about demographic status, past medical history, physiologic parameters and cardiac anesthesia risk evaluation score (CARE score). Statistical tests like Pearson and Spearman correlation coefficients and two-way ANOVA were used (95% confidence interval (CI). A reliable correlation was found between morbidity and CARE score, age, number of previous cardiac surgery, Psychological disease, diabetes mellitus and hyperlipidemia (p<0/001, p<0/001, p<0/001, p<0/001, p=0/001, p=0/007). A largest number of patients were uncomplicated (35/4%) (range=0-4), only 7% of patients had 4 complications. CARE score, age, number of previous cardiac surgery, psychological disease, diabetes mellitus and hyperlipidemia were independent predictors associated with morbidities after cardiac surgery. We need further prospective multicenter studies to develop a useful predictor models.
