ORIGINAL_ARTICLE Validity and Reliability of Perception of Sexually Transmitted Infections Questionnaire among Homeless Women Aim: The aim of the study was to assess the validity and reliability of a native questionnaire (Perception of Sexually Transmitted Infections Questionnaire) among homeless women as a hidden layer in the Iranian society for sexually transmitted infections.Methods: Qualitative and quantitative content and face validities were applied. In the qualitative phase of content validity, the homeless women evaluated wording, grammar, item allocation, and scaling of the questionnaire. In the quantitative phase, the content validity index (CVI) and the content validity ratio (CVR) were calculated. In the qualitative phase of face validity, 40 homeless women were asked to evaluate the questionnaire and indicate if they felt difficulty or ambiguity in the questionnaire. In the quantitative phase, the impact score was calculated. The Kuder-Richardson correlation and test-retest reliability were calculated to assess the internal consistency and stability of the questionnaire.Findings: The ICC for the questionnaire was achieved at 0.86 (good to excellent), lending support to the stability of the questionnaire. The Kuder-Richardson correlation of the questionnaire was 0.85 (good to excellent). Impact scores of the items ranged from 1.2 to 5. In the quantitative content validity, items with CVR and CVI less than 0.59 and 0.79, respectively, were omitted; overall, 10 items were deleted in this part of the validity.Conclusion: This study suggests that PSTIQ is a valid and reliable. It could be used to design appropriate interventions to prevent (STIs) in high risk groups, especially homeless women. http://hehp.modares.ac.ir/article-1-10544-en.pdf 2017-10-18 5 11 Validity and reliability Sexually transmitted infections Homeless women Leila Allahqoli 1 Assistant Professor, Endometriosis Research Center, Iran University of Medical Sciences (IUMS), Tehran, Iran AUTHOR Azam Rahmani 2 Assistant Professor, Nursing and Midwifery Care Research Center, Tehran University of Medical Sciences, Tehran, Iran AUTHOR
ORIGINAL_ARTICLE Evaluation of the Relationship between Perceived Social Support and Mental Health of Students in Tehran Aim: People receive social support from family, peers, and other social systems. Within this wide spectrum, social networks that support people unofficially involve the group of family and peers. The aim of this study was to determine the relationship between perceived social support and mental health of students in Tehran.Methods: This descriptive and analytical study was conducted on 227 students in Tehran using two questionnaires including the General Health Questionnaire (GHQ-28) with 28 questions, and the social support inventory with two scales of Perceived Social Support from Family (PSSFA) and Perceived Social Support from Friends (PSSFR). The collected data were analyzed via SPSS18 software using Pearson correlation test.Findings: The results showed that mental health had significant relationship with the total score of social support (p<0.05, r=0.197). Furthermore, concerning the other subscales, anxiety and sleep disorders (p<0.02, r=0.155) and social functioning (p<0.006, r=0.190) showed significant relationship with mental health. However, there was no significant correlation between PSSFR and mental health.Conclusion: As proved by the results of this study, when social support is stronger, an individual will have a better mental health status. Moreover, people who experience a higher level of family support have a better mental health status. http://hehp.modares.ac.ir/article-1-1092-en.pdf 2017-10-18 13 19 Mental health Social support Students majid amirsardari 1 M.Sc. of Health Education and Promotion, Department of Health Education and Promotion, Faculty of Health, Tehran University of Medical Sciences, Tehran, Iran Email: amirsardari.m@gmail.com AUTHOR Zeynab Karimi 2 M.Sc. of Health Education and Promotion, Department of Health Education and Promotion, Faculty of Health, Tehran University of Medical Sciences, Tehran, Iran AUTHOR shadi fathizadeh 3 Ph.D. Candidate of Health Education and Promotion, Department of Health Education and Promotion, Faculty of Health, Isfahan University of Medical Sciences, Isfahan, Iran AUTHOR Freshteh Khatti 4 Ph.D. Candidate of Health Education and Promotion, Department of Health Education and promotion, Faculty of Health, Isfahan University of Medical Sciences, Isfahan, Iran AUTHOR
ORIGINAL_ARTICLE Effect of Socioeconomic Factors on the Constructs of the Modified Theory of Planned Behavior in Relation to Reproductive Health in Adolescents: Cross-sectional Study Aim: The aim of this study was to determine the effect of socioeconomic factors on the constructs of the modified Theory of Planned Behavior (TPB) in relation to reproductive health in adolescents.Methods: A cross-sectional study was conducted among 578 female students aged 12-16 years, recruited through a multistage random cluster sampling method, in Tehran, Iran. A self-administered TPB-based constructed questionnaire was designed and used for data gathering. Multivariate regression analyses were conducted to examine the association between family size, number of siblings, birth rank, and family closeness, source of information, and reproductive health behavior.Findings: The mean age of the participants was 14.1 years. None of the participants obtained a perfect score in relation to reproductive health. In addition, they achieved average scores less than half the rates. Number of siblings, family size, birth rank, mother education and information source were factors associated with TPB the constructs (p<0.001).Conclusion: The results of this study emphasize that Socioeconomic factors can have an effective role in students' sexual and reproductive health behaviors. http://hehp.modares.ac.ir/article-1-11498-en.pdf 2017-10-18 21 35 Reproductive health Socioeconomic Theory of planed behavior Adolescents Fatemeh Darabi 1 Ph.D. in Health Education & Promotion, Assistant Professor, School of Asadabad Medical Sciences, Asadabad, Iran AUTHOR Mehdi Yaseri 2 Assistant Professor, Department of Epidemiology and Biostatistics, Faculty of Health, Tehran University of Medical Sciences, Tehran, Iran AUTHOR Farideh Khalajabadi Farahani 3 Associate Professor, Department of Health Education and Health Promotion, Faculty of Health, Shiraz University of Medical Sciences, Shiraz, Iran AUTHOR Aghbabak Maheri 4 Department of Health Education and Promotion, School of Public Health, Tehran University of Medical Sciences, Tehran, Islamic Republic of Iran AUTHOR Mohammad Hossein Kaveh 5 Associate Professor, Department of Population, Health and Family Planning, National Institute for Population Research, Tehran, Iran AUTHOR
ORIGINAL_ARTICLE A New Multi-objective Optimization Model for Diet Planning of Diabetes Patients under Uncertainty Aim: The objective of this paper is to design nutrient-adequate, varied and cost-efficient diets for diabetes patients.Methods: A new multi-objective mixed integer linear programming model under uncertainty is developed to design diet plans for diabetes patients.Findings: The analysis is conducted on the population of 30 years old men and women in 24.99 and 18.5 body mass index, 1.50, 1.65 and 1.80 (m) height categorized in 4 physical activity levels (sedentary, low, active and very active). The objectives of the model are the minimization of the total amount of saturated fat, sugar and cholesterol and the total cost of the diet plans. The constraints of the model are fulfilling the body's nutrient requirements and the diversity control of each patient’s diet. In order to get closer to the real world, fuzzy parameters are considered in the model. To solve the model, a new hybrid solution methodology (Jimenez and epsilon-constraint method) is used to offer the optimal Pareto of non-dominated solutions. Each optimal Pareto of the model consists of diet plans that each patient can choose the proper food based on the taste, availability and cost.Conclusion: Mathematical modeling of diet planning and study of its optimal solutions can be considered as a decision support tool for the professionals to design the most proper diet plans. http://hehp.modares.ac.ir/article-1-10693-en.pdf 2017-10-18 37 55 Diet planning problem Multi-objective fuzzy mixed integer linear programming Jimenez method Epsilon-constraint method Maryam Eghbali-Zarch 1 Ph.D. Candidate, School of Industrial Engineering, College of Engineering, University of Tehran, Tehran, Iran AUTHOR Reza Tavakkoli-Moghaddam 2 Professor, School of Industrial Engineering, College of Engineering, University of Tehran, Tehran, Iran AUTHOR Fatemeh Esfahanian 3 Associate professor, Department of Endocrinology & Metabolism, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran AUTHOR Amir Azaron 4 Associate professor, Beedie School of Business, Simon Fraser University, Vancouver, Canada AUTHOR Mohammad Mehdi Sepehri 5 Professor, Department of Industrial Engineering, Tarbiat Modares University, Tehran, Iran AUTHOR
ORIGINAL_ARTICLE Mobile Learning Impact on Blood Glucose Control among People at Risk of Type 2 Diabetes Referring to Ahvaz Diabetes Consultation Center Aim: Type 2 diabetes is a preventable disease and can be prevented in people at risk by doing appropriate interventions and selecting new educational practices. Mobile learning is one of the modern educational techniques used for providing opportunities for the transmission of information, as well as strengthening and improving lifelong learning for learners. We aimed to investigate mobile learning impact on blood glucose control in people with type 2 diabetes referred to Ahvaz Diabetes Consultation Center.Methods: This semi-experimental study was conducted on 60 samples selected by the random stratified sampling method. The subjects were divided into two groups: experimental group and control group. In this study, data were measured using the fasting blood sugar, DPS software and the demographic questionnaire. Before the start of the intervention, demographic profile and fasting blood sugar level were recorded in the relevant form. A designed software program was loaded on the cell phones of the experimental group. After three weeks, the blood samples were taken. Data were analyzed using the descriptive-analytical statistics tests. The significance level was considered to be less than 0.05.Findings: The findings showed that the positive effect of implementation the training program by mobile learning method was statistically significant in the control of blood sugar in the experimental group (P<0.001).Conclusion: Mobile learning is one of the modern educational practices that can be used to control blood glucose in people at a higher risk of type 2 diabetes. The use of educational technology can be considered as a good way to help the improvement of the health outcomes and behavior of people at risk for diabetes. http://hehp.modares.ac.ir/article-1-3131-en.pdf 2017-10-18 57 67 Mobile learning Type 2 diabetes Ahvaz Banafsheh Mahjoob 1 M.Sc. in Educational Technology, Faculty of Medical Sciences, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran AUTHOR Seyedeh Somayeh Kazemi 2 Ph.D. Candidate of Health Education & Promotion, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran AUTHOR
ORIGINAL_ARTICLE Investigating the Quality of Life of Healthy Elderly Volunteers in the Health Centers of Shahid Beheshti University of Medical Sciences, 2016 Aim: Aging is a process that involves all living creatures, including human beings. Statistical indicators show that the aging trend is progressing in Iran, too. The volunteer women cooperating with the urban areas’ health system (called Healthy Volunteers) are amongst the pioneers and symbols of health care social participation.Methods: This cross-sectional study was performed on 86 elderly members of the healthy volunteer group of health centers. Data collection instruments consisted of demographic information and LEIPAD questionnaires. Data were analyzed using SPSS18 and descriptive and analytic statistics.Findings: The mean age of the participants was 64±4.007 years. The mean total score of QOL was 72.7±11.32. The mean score of the seven dimensions of QOL was as follows: physical function (71.5%), self-care (92.4%), social function (76.7%), anxiety and depression (82.8%), life satisfaction (67.9%), sexual function (71.5%) and cognitive function (78.9%). There was no significant relationship between QOL the variables such as age, educational level, marital status and number of family members (P>0.05). However, the relationship between QOL and the duration of elderly cooperation was significant (r=0.23, P<0.05).Conclusion: The results showed that the quality of life in healthy volunteers was moderate. Therefore, health volunteers as elderly persons are role models and can take effective steps in the transfer of health information in the community. http://hehp.modares.ac.ir/article-1-2290-en.pdf 2017-10-18 69 77 Elderly Quality of life Healthy volunteer Tayebe Marashi 1 Assistant Professor of Health Education, School of Public Health, Shahid Beheshti University of Medical Sciences, Tehran, Iran AUTHOR Neda Ghobeh 2 M.Sc.
