Introduction: health literacy is a fundamental part of the healing promotion. The aim of this study was to evaluate periodontal health literacy among patients. Materials and methods: 296 patients attending periodontal clinic who were above 16 years old participated in this study. Gathering data was based on screening questions on a 5-point Likert scale. After completion questionnaire, data was analyzed by Mann-Whitney and Kruskal-Wallis test. Based on the scores of questions, patients were classified as weak, medium and good health literacy. Result: This study showed significant difference in health literacy between age and education groups (P value = 0.015, P value = 0.003), while there was no significant difference between male and female (P value = 0.54). It was also revealed that patients who had been exposed to oral health education had higher health literacy levels ( P value < 0.0001, P value = 0.001). Conclusion: The results of this study showed patients less than 20 years and over 50 years old had poorer heath literacy in relation of periodontal heath, also, patients with higher educational level have higher health literacy.

Background: Dental fear is a major factor in postponing and cancelling a dental appointment. The studies in this field are still limited. The current study was conducted to examine dental fear in patients going to dentists in Mashhad, Iran. Materials and Methods: In this descriptive study, 400 patients were selected randomly from 20 dental offices in Mashhad. The data were collected, using Dental Fear Scale. The reliability and validity of the questionnaire have been measured and confirmed in previous studies. The data were analyzed, using the SPSS software to perform t-test, ANOVA, Spearman’s rank-order correlation coefficient, and Pearson’s product-moment correlation coefficient. Results: Nearly 20.8% of the participants had mild, 57.5% had moderate, and 21.8% had severe dental fear. The mean score of fear was statistically higher in females (49.95±13.3) compared to males (39.69±14.7). In terms of marital status, the highest mean score of fear was observed among the divorced and widows (51.82 ± 14.2). In terms of occupation, the highest mean score of fear was observed among the housewives (52.63±12.89). Correlational analysis showed the following inverse relationship between dental fear score and age(r=-0.18,p<0.001), education level(ρ=-0.28,p<0.001)and income level (ρ=-0.39,p< 0.001). Conclusion: females, particularly housewives, have a significantly higher level of dental fear, and it had an inverse correlation with age, education level and level of income and they should be considered in interventional and educational programs aimed decreasing dental fear level.

IntroductionSince diabetes is a complex network of psychological and healthcare factors, this paper aims to investigate the relation between type 2 diabetes and mental health
Method: This study was analytical cross-sectional research on 60 diabetic patients referring to Kazerun health care centers, southwest of Iran, in 2018. The samples were selected by convenience sampling method. The data were collected using the Demographic Profile Questionnaire, General Self-Efficacy Scale  (GSES), Health Literacy Questionnaire  (HELA), and Mental Health Continuum (MHC-SF). Data analysis was performed in APSS v21 and from descriptive statistics including mean and standard deviation and using the statistical tests of Spearman correlation coefficient and multiple regression analysis (P <0.01).
Findings:   Mental health has a significant positive relationship with health literacy (p <0.001). Thus, individuals with better mental health evaluate their level of health literacy better. However, no relationship was found between self-efficacy and health literacy(r= -0.19, p >0.001). Besides, regression results indicated that mental health can predict a 54% variance of health literacy (R²= 0.54, p <0.001).
Conclusion: The findings of this study shows that boosting an individual’s mental health leads to an increase in health awareness in patients afflicted with diabetes which after all, can cause a better coping capability in these people.

Introduction:   Muscle weakness and balance problems are limiting factors in Multiple sclerosis patients that can be improved due to physical activity. The purpose of this study was to investigate the effect of 8 weeks of aerobic exercise on balance function and Physiological Cost Index in patients with MS in Yazd city in 1394.
Methods: This quasi-experimental study was conducted in two stages: pretest and post-test. The subjects were selected by targeted and available sampling and randomly divided into training and control groups that included 30 patients (15 in the experimental group and 15 in the control group). The subjects were randomly divided into two groups of experimental and control. Subjects in the experimental group participated in an aerobic exercise program for eight weeks, three days a week, each session of 60-90 minutes with an intensity of  50-70% of maximum heart rate. For statistical analysis we used descriptive statistics such as mean, standard deviation, and the Shapiro-Wilk test used to measure the normality of the data, independent t-test and the covariance (ANCOVA). The significance level of the tests was p < 0.05 by using the SPSS-25 software.
Results:   ANCOVA results revealed that the selected aerobic training significantly increased both static balance (p = 0.007) and dynamic balance (p = 0.001). Moreover, aerobic training positively influenced the physiological cost index (P = 0.001.
 Conclusion: aerobic exercise can improve both static and dynamic balance and increase the Physiological Cost Index in M.S patients. Therefore, these exercises are recommended for patients with MS.
