Abstract
Background and Aim: Iron deficiency is one of the most common nutritional problems during pregnancy. The purpose of this study was to assess the theory of planned behavior structures on nutritional prophylactic treatment of anemia in pregnant women of Arak city in 2018.
Materials and Methods: This is a cross-sectional study that was carried out on 199 pregnant women in Arak city using simple random sampling in 2018. The data were gathered with valid and reliable researcher-made questionnaire including demographic information and the theory of planned behavior structures. The study was conducted to determine the most important predictive constructs of pregnant womens’ behavior using a multivariate linear regression model.
Findings: The finding showed that mean age of mothers was 28.81 ± 5.1 years and the mean weekly gestation was 28.04 ± 8.9 weeks and the gestational interval with previous pregnancy was 5.18 ± 3.9 years. Mean±standard deviation of attitude score (3.61 ± 0.62), subjective norm (3.60 ± 0.74), perceived behavior control (3.50 ± 0.58), behavioral intention (3.49 ± 0.61), performance (3.55 ± 0.76) and awareness (0.57±0.2) were observed. Linear regression model showed that the performance score of pregnant women improved for each unit of attitude and subjective norms and perceived behavioral control, respectively, by 0.463, 0.343 and 0.347, respectively.
Conclusion: The results emphasize the provision of educational programs on the prevention of anemia in pregnant women with an emphasis on attitudinal structures, mental norm, and perceived behavioral control. It is suggested that at the time of designing interventions to improve the prevention of anemia in pregnancy, the structures of the theory of planned behavior should be considered.

Abstract
Introduction: The use of digital games is highly prevalent among adolescents and can adversely affect their physical and mental health. The aim of this study was to determine the predictors of the stages of change in problematic digital games in high school students using a transtheoretical model.
Methods: This descriptive-analytical cross-sectional study was performed on 703 high school students in Bushehr 2020. A valid and reliable researcher-made questionnaire was performed for data gathering and analyzed using SPSS ver. 22 by descriptive indices, one-way ANOVA, chi-square, and rank ordered logistic regression. The present research was approved at Research Ethical Committee of Bushehr University of Medical Sciences (Code: IR.BPUMS.REC.1398.101).
Results: According to the results, self-efficacy, dramatic relief and social freedom were the predictors of the change stages of reducing and quitting digital games. This means that girls and students with higher self-efficacy (P = 0.037, OR = 1.054), have a better chance of being in higher stages of change and by increasing a unit of dramatic relief score (P = 0.025, OR = 1) and social freedom (OR = 1.135, P <0.001), the chances of individuals to be in the upper stages of change increased.
Conclusions: It seems that the design of educational interventions based on self-efficacy variables and taking into account the change processes of dramatic relief and social freedom, which increase the chances of people to be placed in higher stages of change, in reducing the behavior of digital games of students, especially for boys will be effective.

Abstract
Introduction: One of the biggest environmental challenges of the 21st century is the phenomenon of climate change and global warming, which can cause numerous health problems. One significant health issue associated with climate change is the increase in the prevalence of heat stress, particularly in occupational encounters in hot outdoor environments. So this study aimed to predict and model temperature and humidity indices in the coming decades in a dry climate.
Methods: This study obtained daily atmospheric parameters, including minimum temperature, maximum temperature, and relative humidity of Kerman station, representing a dry climate, for a period of 30 years (1965 to 2005) from the meteorological organization. Modeling of these parameters and calculation of the Temperature and Humidity Index (THI) were performed using the atmospheric general circulation model HadGEM2-ES and the CORDEX dynamic microscaler model. Three different radiative forcing scenarios, including optimistic (RCP 2.6), intermediate (RCP 4.5), and pessimistic (RCP 8.5), were considered for the coming decades (three 30-year periods from 2011 to 2099). The Ethics Committe of Iran University of Medical Sciences (IUMS) approved the present study (Code: IR.IUMS.REC.1400.020).
Results: The results of the study showed an increasing trend for minimum and maximum temperature parameters in all three time periods using the three scenarios considered. Moreover, the increase in temperature in the decades of 2099-2071 was more pronounced compared to the previous decades. The results also demonstrated an increasing trend in the THI index based on all three scenarios. The average results obtained using these scenarios showed an increase of 2.11, 2.53, and 3.3 degrees Celsius, respectively, in this index until the end of the last century compared to the base decades.
Conclusions: Overall, the increase in temperature and the investigated THI index in the studied station, based on all three scenarios, will lead to changes in thermal comfort. Higher levels of thermal discomfort will not only occur in hot months and seasons but also in other seasons. Therefore, proper planning should be implemented to address the adverse effects of climate change on people's health.
