Abstract
Introduction: With ever improving technology and increasing the use of high voltage power in industrial environments, concerns about the destructive effects of electromagnetic waves on human health have increased. Thus the present study aims to evaluate the effects of electromagnetic waves on the general health of Zahedan gas power plant personnel.
Materials & Method: The present case-control study investigated the health of people at one point of time and their amount of exposure to electromagnetic waves at the same time. The data collection tool in this study was 28-item general health questionnaire (GHQ-28). After measuring the electromagnetic waves at distances of 1, 1.5 and 3 meters at high voltage power substations and data extraction, the data were entered to SPSS software and analyzed by descriptive statistics, t-test and chi-square.
Results: In this study, the age and experience variables were not significantly different in two groups (p> 0.05). The highest magnetic fields in high voltage power substations was at a distance of 1 meter in the substation 607 (28/1 mG) and in precision tool work units (7.03 mG). The results showed that the depressive and general health symptoms were significantly different between the exposed and unexposed groups (p = 0.04), however the difference was not significant in terms of physical performance, anxiety and social performance (p> 0.05).
Conclusion: although the level of exposure was lower than standard level determined in Iran, the significant difference of the general health and depression between the two groups, explains the necessity of conducting more studies in this regard. Also by reducing the exposure time and increasing people’s awareness it is possible to take important steps to reduce exposure and complications.

Abstract
Introduction: Health literacy is defined as the ability of an individual to acquire, interpret, and understand the basic information about health services and to use them. Health literacy is a strong predictor of health. Its low level is germane to health problems of people and society as well as economic costs. This study was designed to determine the level of health literacy considering socio-demographic factors in residents of Alborz province in 2015.
Methods: This is a cross-sectional study in which 465 people aged between 18 and 60 years old living in Alborz province were evaluated using two-stage random sampling technique (stratified and cluster sampling). In this study, Iranian Health Literacy Questionnaire (IHLQ) and socio-demographic Information Questionnaire were used to collect the required data. The data were analyzed using descriptive statistics as well as T-test, Mann-Whitney test, and Spearman correlation test using SPSS software.
Results: The mean age of participants was 36.57(±11.08) years old and 68.2% of them were female. 22.4% of people had adequate, 44.3% had a moderate, and 33.3% had a poor level of health literacy. Health literacy in all dimensions of IHLQ except individual empowerment and social empowerment was moderate. People's access to health information also was moderate. The T-test indicated that the health literacy score was significantly higher in the individuals with the educational level of diploma and higher (p= 0.000), in Persian people (p= 0.008), and in unemployed people (p= 0.006).
Conclusion: The high level of inadequate (moderate and poor) health literacy of 77.6% of the Alborz province population should be taken into consideration in health system policies to apply an effective strategy for promoting health literacy that results in better health status, regarding effective socio–demographic factors for each dimension of health literacy.

Abstract
Introduction: Firefighting is one of the occupations that require high physical and aerobic power due to the nature of the job and the physical demands of this profession. Therefore, the present study aimed to investigate the relationship among Work ability index (WAI), mental workload, musculoskeletal disorders (MSDs) and their effective factors in firefighters.
Methods: This study was a cross-sectional study, which was carried out on 250 firefighters in Tehran. Data were collected using WAI, NASA-TLX and Body Discomfort Chart (BDC). Data analysis was carried out using descriptive statistics, linear regression, Pearson correlation and Spearman tests.
Results: The mean and standard deviation of the total WAI score was 38.85±1.17. Also, the highest amount of mental workload was devoted to the physical load dimension (93.49±8.93). Meanwhile, the total mental load was also 70.07 ± 6.58. The results showed that the WAI is increased by 0.14 by augmentation of one unit at the academic level of firefighters (P = 0.03). The most common discomfort was reported in the lower (20%) and upper (16.8%) regions of the back. The total WAI relationship with total mental workload was positive and insignificant (P>0.05). There was a significant and reverse association between WAI and discomfort in wrist, leg and ankle.
Conclusion: Despite the low rate of MSDs, even mild symptoms of musculoskeletal pain should be considered. Given the high level of mental workload, improving physical, psychosocial and social working conditions is important in increasing the ability of employees and augmenting the ability of their occupational activity.

Abstract
Introduction: Iranian students of health need to bone up on their academic English to be able to read the English sources of health as a factor contributing to community health promotion. In the Iranian academia, students are placed in Basic and General English courses not on the basis of proficiency levels, but on the basis of their academic majors with the same protocol, teaching materials, and methodology used for these heterogeneous classrooms leading to failure and dissatisfaction in the use of academic English as a vehicle for increasing their knowledge of community health. This study investigated the effect of English proficiency homogenization on linguistic proficiency of Iranian students of health as a means of health enhancement via reading English sources.
Methods: In this quasi-experimental study conducted in 2018, the Cambridge Placement Test was given to 71 students of three health majors at Shahid Sadoughi University of Medical Sciences selected with convenient sampling method. The students were divided into three language ability groups using placement test percentiles and taught with two different protocols which were used till the midterm exam. The midterm exam was given and the data were collected and analyzed with SPSS20 using descriptive statistics, i.e., frequency, percentiles, mean, and standard deviation and also inferential statistics, i.e., one-way ANOVA, Levene statistic, Tukey HSD, and independent T-test.
Results: A significant difference was found between the three groups on the placement test (p=0.015); there was no significant difference among the three different academic majors with regard to Criterion-referenced Test (CRT) scores (p=0.05); there was no significant difference among the three Norm-referenced Test (NRT) forms (Forms A, B, & C) (p=0.05); also, there was a significant difference among the two CRT forms (Forms A, B) (p=0.05). Regarding the placement test, the significance indices demonstrated a significant difference between group A, on the one hand, and groups B and C, on the other with no significant difference between groups B and C (p=0.05). The findings of the second part of the post hoc test showed a significant difference for the midterm exam between Group A, on the one hand, and Group B and Group C (p=0.05), on the other, with no significant difference between groups B and C (p=0.05), indicating the success of the present study.
Conclusion: The students of health should be grouped in Basic English and EGP courses, not based on their academic majors, but based on their English proficiency levels for a successful English pedagogy leading to successful use of English texts of health as a means of promoting health community.

Abstract
Introduction: Anxiety disorders are common psychiatric disorders in children and adolescents. It seems that the parent-child interaction affects or exacerbates the creation of anxiety disorders in children. The present study aimed to compare the effectiveness of mindfulness and happiness training in promoting parent-child interaction in mothers of anxious preschool children.
Methods: The research method was experimental with a pretest-posttest design and control group. The statistical population included all mothers of pre-school anxious children in Shahrekord in 2018. Using the multistage sampling method, 45 people were selected and put randomly in the control and two experimental groups (n=15 per group). The Spence Children's Anxiety Scale (SCAS) and Pianta's Child-Parent Interaction Questionnaire (PACHIQ) were used for data collection. Experimental groups were put under mindfulness (eight 90-minute sessions) and happiness (ten 90-minute sessions) training, but the control group did not receive any intervention. Analysis of the data involved both inferential and descriptive statistics including mean, standard deviation. Data analysis was conducted using one-way analysis of variance (one-way ANOVA) and analysis of covariance (ANCOVA). SPSS version 24 was further used for analyzing the data. The significance level of research was considered to be α=0.05.
Results: The results indicated that both mindfulness (p=0.0001) and happiness (p=0.0001) training increased parent-child interaction in mothers of anxious preschool children. The mean ± SD of the post-test score of parent-child interaction in the control group was 96.73±7.89 which was significantly different from the experimental groups (p=0.0001). Furthermore, there was no significant difference between the effectiveness of mindfulness (117.80±4.47) and happiness training (115.46±4.65) in promoting parent-child interaction in mothers of anxious children (p=0.599).
Conclusion: Mindfulness and happiness training were effective in improving parent-child interaction in mothers of preschoolers with anxiety and could similarly change the parent-child interaction in mothers of anxious children.
