Background: Attention to the increase of students' physical activity is one of the goals of Healthy People 2020. The aim of this study was to determine the effect of education on the students' physical activity by using two methods of lecturing and the peer group.
Methods: In this quasi-experimental study, 142 female students (aged 12-15) were randomly selected and divided into two groups: lecture (n=71) and peer group (n=71). Two physical activity questionnaires; the Physical Activity Questionnaire for older Children (PAQ-C) and the International Physical Activity Questionnaire-Short Form (IPAC-Short Form), were filled out by the students in two phases, before educational intervention and eight weeks later. Data were analyzed by SPSS version 20 using the parametric (independent and paired sample t-tests) and non-parametric tests (Man Whitney U and Wilcoxon Signed-Ranked tests).
Results: The results of the study showed that the hypothesis: "the effect of the educational intervention program using two methods of lecture and education in the peer group is different on the physical activity of students" was accepted. In both groups, the level of physical activity was low in the beginning of the study. However, eight weeks after the educational intervention program, a significant increase was observed in the physical activity of students in the peer group, in comparison to the students in the lecture group using both questionnaires; i.e. PAQ-C (p<0.001) and IPAQ-Short Form (p<0.001). Also, measurement by two questionnaires showed that the number of students with low physical activity in the peer group declined (p=0.001), and the number of those with moderate physical activity was notably added (p<0.01).
Conclusions: Dynamism in the peer group causes sustainable learning in the domain of psychomotor skills. Therefore, this active teaching method can be developed in schools for increasing learning motivation of students in health programs by school or community health nurses.

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the most frequent liver diseases worldwide. There are several com- mon risk factors between NAFLD and coronary artery disease (CAD). Objectives: This study aims to evaluate the relationship between the prevalence of Non-alcoholic fatty liver disease (NAFLD) withseverity of Coronary Artery Disease (CAD) in patients undergoing coronary artery angiography. Methods: This study was a cross-sectional, descriptive-analysis research that included 514 patients who underwent angiography.The severity of CAD was assessed by the number of vessels involved (vessel score: vd). An ultrasound was performed for all the patients also, intensity of fatty liver involvement was graded from zero (absence of steatosis) to three (severe steatosis). Results: Ultrasonographic examination proven NAFLD in 59.1% of patients with different grades. Patients with NAFLD had signifi- cantly higher body mass index (P < 0.001), waist circumference (P = 0.03), and age (P < 0.001). In addition, there were significant differences between ALT and AST within the normal group and NAFLD patients (P < 0.001). Moreover, coronary angiographic data indicated that the presence of NAFLD significantly correlated with the CAD severity score as so: 64% of people with 2vd and 60.5% of people with three-vessle lisense had fatty liver that was statistically significant (df = 4; P = 0.014). Conclusions: This study showed a high prevalence of NAFLD in patients with documented CAD. It is extremely important since knowing risk factors, designing screening programs, and early treatment of fatty liver could lead to reducing the risk of cardiovas- cular diseases.
