Abstract
Background and Aim: This study was undertaken to determine the effectiveness of a safe community program, as an international community-based program, for injury prevention and safety promotion, in Kashmar
Materials and Methods: In this retrospective study, the data on injured patients consulting hospital emergency wards in Kashmar and 44 other districts (as control) for a period of 3 years (March 20 2005 to March 19, 2008) were analyzed and compared.
Results: The number of injuries/100,000 population in Kashmar was 4654.6, 4570.9, and 4949.2 in March 2005-2006, 2006-2007, and 2007-2008, respectively. The corresponding figures (means) for the control districts were 822.7, 1130.0 and 1245.5. The injury- related fatality rate in the emergency ward for the 3 periods was 57.6, 52.9, and 44.2 per 100,000 in Kashmar and 12.2, 13, and 11.9 per 100,000 in the control districts. The injury rate showed an increase and the injury- related fatality rate showed a decrease in both Kashmar and the control districts over the 3 year period, but there was a statistically significant difference between the decreased injury-related fatality rate in Kashmar (p<0.0001).
Conclusion: The Kashmar International Safe Community Program resulted in no significant decrease in the rate of injuries in Kashmar. However, as compared to the control distrcts, it caused a decrease in the injury-related fatality rate over the 3-year period. Long-term studies are necessary to confirm these results.

Abstract
Background and Aim: Lead is a toxic metal used in different industries and occupational and environmental exposure to it is quite likely to occur. Because of its high potential toxicity, serious damages to those exposed to it are common. Since the ceramic industry, in which lead is used, is considered a domestic industry in Iran, in this study occupational exposure of glaze workers to lead was assessed in a ceramic industry.
Materials and Methods: A total of 55 glaze workers (39 tillers and 16 potters) were selected as the case group. Association of lead concentration with several variables, including work shift, work type, ventilation system, and the number of extra work hours during the previous month, was determined. A sampling pump (SKC Co.) and ester cellulose filters with a pore size of 0.8 µm, 37 mm in diameter, were used for sampling. The flow-rate was adjusted at 2 l/min based on the NIOSH 7300 method. After sampling, filters were transferred to the laboratory and digested in a mixture of nitric acid and per chlorate solution (4:1) and analyzed by ICP-AES. To minimize probable errors and pollution during sampling and sample handling, samples were also taken from employees in the administration department to serve as control. Spiro metric tests were performed on both the case and the control groups.
Results: The lead concentrations were higher than the threshold limit value (TLV) (0.17 mg/m). Independent t-test showed that there was a significant relation between concentration of the lead present in the breathing zone air and 2 independent variables, including shifts work (morning and afternoon) and the ventilation system among tillers. Also, based on the one-way ANOVA, there was a significant relation between concentration of the lead present in the breathing zone and the number of extra working hours over the shift.
Conclusion: The mean lead concentration in the breathing zone was higher than the respective TLV. Considering the hazardous nature of lead, protective measures─ personal, occupational and environmental─ should be taken. Moreover, clinical examination of job applicants at the time of employment, as well as periodic examinations and Spiro metric tests on the workers, are also strongly recommended.

Abstract
Background and Aim: Presently not sufficient attention is paid to adolescent health promotion in many countries, because of the widespread belief that adolescents are generally healthy. The purpose of this study was to evaluate predictors of adolescent girls' quality of life using path analysis based on Pender's health promotion model.
Materials and Methods: The Pender's health promotion model served as the framework of this cross-sectional study, which included a total of 500 adolescent girls (grades 9-11) selected by stratified random sampling from 20 high schools for girls in 4 districts of Kashan province, Iran. Inclusion criteria were being in grades 9-11 and a written informed consent (from teachers, parents and the girls themselves). Data were collected through interviewing the girls, the interviewers being trained persons, using several standard questionnaires (for perceived self-efficacy, perceived affect, perceived barriers, perceived social support health promoting lifestyle, and health-related quality of life). Data analysis was done using SPSS18 and LISREL 8.8, the statistical test being path analysis.
Results: All constructs of the health promotion model and health promoting lifestyle were significantly related to adolescent girls' quality of life. Perceived self-efficacy (β=0.70, p<0/01) and perceived affect (β=0.21, p<0/01) had the highest correlation with the quality of life. The model and the health-promoting lifestyle as a mediator accounted for 73% and 39% of variance in adolescent girls' quality of life, respectively.
Conclusion: The findings of this study indicate that the health promotion model can be used to explain and predict the quality of life of adolescent girls. Thus, the Pender's health promotion model is recommended to health planners for promoting the quality of life in this population.

Abstract
Background and Aim: Many researchers have studied survival (time to death) of gastric cancer patients. Although gastric cancer diagnosed in early stages can be cured by surgery, chance of relapse still exists after operation. Hence, we should consider both events, that is, relapse of the disease and death, in order to be able to make a more precise estimation for survival of the patients. The purpose of this study was to use the competing risks method to estimate the cumulative incidence functions (CIF) of the relapse of disease and death and consequently to estimate the postoperative disease-free survival.
Materials and Methods: A total of 330 patients admitted to Iran Cancer Institute and operated between March 1995 and March 1999 were enrolled in the study. They were followed up for at least 5 years to estimate their 5-year disease-free survival. Information on their demographic, clinical, and therapeutic characteristics, as well as on the type and time of occurrence of the first event (relapse of disease or death) after surgery was collected from their medical records. The direct parametric method was applied to estimate CIFs of relapse of the disease and death, while to adjust the effects of some covariates the parametric regression model was used. Data analysis was done using the R software and a p-value <0.05 was considered statistically significant. The findings were compared with the results obtained on the basis of data analysis in which the competing events were not considered.
Results: The median follow-up time was 37.9 months. Of all the patients 13% experienced relapse and 60.9% death as the first event after surgery. The CIFs of relapse of disease and death 5 years after operation, with due consideration of covariates, were estimated at 11.0% and 68.6%, respectively. Age, stage of disease, and complementary treatment were statistically associated with the CIF of death, while only complementary treatment was related to the CIF of relapse. Older patients and those in more advanced stages of disease were more likely to die after operation. Moreover, while complementary treatment after operation decreased the CIF of relapse of disease, it increased the CIF of death. The disease-free survival of patients 5 years after surgery was 20.(consideringtheeffectsofsomecovariates).
Conclusion: The competing risks method is recommended for analyzing survival data because of its capability in considering different events and, therefore, making it possible to make more precise estimations. By using this method, considering smaller variance estimates for model parameters and also narrow confidence intervals for the cumulative incidence functions of competing events, it is expected to obtain more precise results. Unfortunately, the results have revealed that the disease-free survival of gastric cancer patients is low in Iran.

Abstract
Background and Aim: Determining the degree of conformity of respirator cartridges with the accepted standards is very important for ensuring their respiratory protection efficiency. The aim of this study was to determine the degree of conformity of organic vapor-respirator cartridges used in different petrochemical companies with the EN 14387:2004 standard.
Materials and Methods: In the first phase of the study, the respirator cartridges used in petrochemical complexes were identified and their specifications obtained from their manufacturers and the relevant technical catalogues. In the second phase, 3 samples of each of the cartridge models were chosen and tested according to the EN 14387:2004 standard. An instrument was especially designed for measuring the breakthrough time of the cartridges.
Results: The results showed that the minimum and maximum breakthrough times of cartridges were 29 and 142 minutes, respectively. From all the 10 different cartridge models tested, one had a service life of lower than the minimum standard breakthrough time of 70 minutes.
Conclusion: Considering the existence of a non-standard type of cartridge among the samples studied, it is essential to launch a program aiming at ensuring the conformity of cartridge efficiency with the respective standards. Such a program should be developed and implemented by such responsible organizations as the Institute of Standard and Industrial Research of Iran and the Center for Occupational Health and Safety Research and Training of Iran.

Abstract
Background and Aim: Wearing high-heeled shoes increases the height of the center of gravity and takes the line of gravity away from the center of the base of support. This may result in the loss of body balance. In this study the effect of 3 heel heights on the static and dynamic postural stability in healthy young women was investigated.
Materials and Methods: In this cross-over quasi-experimental study with repeated measures, three dynamic indices of anteroposterior, mediolateral, and overall stability were determined using Biodex stabilometer and static stability using a modified CTSIB test. The measurements were made at 4 conditions of the feet, i. e., barefoot, and wearing shoes with a heel height of 3, 5, or 7 centimeters.
Results: The mean static stability index in the barefoot condition was significantly different from that in any the 3 conditions of wearing heels. With the eyes closed, the most unstable condition was in the case of the 7-cm heel, which caused also the most unstable dynamic condition the differences were all statistically significant.
Conclusion: The findings indicate that postural instability increases with increases in the height of shoe heels. On the whole, considering both the static and dynamic stability, the 3-cm heel can be recommended as the optimum-height heel.

Abstract
Background and Aim: Experience at the national and international levels shows that internal evaluation, especially at the level of academic departments, can play a critical role in warranting having a university with high standards. The objectives of the present research project were to determine (a). the quality of the structural elements of the Epidemiology and Biostatistics Department (EBD) School of Public Health, Tehran University of Medical Sciences, and (b). The strengths, weaknesses, opportunities and threats, on the basis of which action could be taken to improve the quality of activities in the Department.
Materials and Methods: The study was conducted with the collaboration of the head and faculty members, all of the students (residents, Ph.D. and M.S. students), and the graduates, of the EBD. Nine variables were studied, namely, 1). Aims and objectives 2). Organizational and management structure 3). Faculty members 4). Students 5). Teaching and learning process 6). Courses and curricula 7). Graduates 8). Research and educational facilities and equipment and 9). Research activities of the faculty members. First the initial weight of the 9 variables were determined by opinion poll carried out among all the faculty members of EBD. Then unrelated data were identified through proper tests and omitted and the final weights extracted. The tools used to collect the data included interview, observation, and 7 self-prepared questionnaires and 2 check lists.
Results: The mean score for the 9 factors studied was 59.8%, the range being between 37.0% (for objectives and mission) and 72.0% (for graduates).
Conclusion: The graduate domain is one of the key areas in internal evaluation of the Department of Epidemiology and Biostatistics. On the other hand, the lower score for objective and aims domain implicates the need for future intervention in this domain.

Abstract
Background and Aim: There is evidence showing that increased inflammatory mediators and reduced serum levels of polyunsaturated fatty acids may be present in patients with neurodevelopment and psychiatric disorders, e.g. attention-deficit/ hyperactivity disorder. (ADHD). The objective of this study was to determine the effects of dietary omega-3 fatty acid supplementation on hyperactivity, attention deficit, and serum inflammatory mediators in children with ADHD
Materials and Methods: This was an 8-week randomized double-blind clinical trial. The participants were 103 6 to12-year old children with ADHD receiving effective maintenance therapy, who were assigned randomly to receive either a daily omega-3 supplement (635 mg eicosapentaenoic acid and 195 mg docosahexaenoic acid (intervention group) or a placebo visually similar to the omega-3 capsules (placebo group). The serum levels of C-reactive protein (CRP) and interleukin-6 (IL-6) were determined at baseline and at the end of the period. In addition, the abbreviated 10-item Conners parent rating scale (CPRS) was completed for each child before and after the intervention.
Results: The intervention brought about statistically significant reductions in the levels of CRP and IL-6 and a significant improvement in the CPRS score in the omega-3 group.
Conclusion: The findings indicate that dietary omega-3 fatty acid supplementation can have desirable effects on hyperactivity, attention deficit and inflammatory mediators in children with ADHD.

Abstract
Background and Aim: Vitamin D deficiency is highly prevalent in Asia, including the Middle East. Vitamin D deficiency has been found to have an inverse relationship with occurrence of type-2 diabetes mellitus (DM). In this study we assessed the vitamin D and calcium status in type-2 diabetic patients and compared it with that of healthy subjects in Tehran, Iran.
Materials and Methods: This cross-sectional study included 180 Tehrani individuals, including 95 DM patients, selected randomly from among the members of Iranian Diabetes Association, and 85 healthy subjects in Tehran, Iran. Age and gender were adjusted between the two groups. Serum levels of 25(OH)-vitamin D, calcium, phosphorous, and Parathormone (PTH), as well as weight, height and body mass index (BMI) were measured.
Results: The mean and SD age and BMI of the diabetic patients were 51.26 ± 11.18 years and 26.22 ± 9.30 kg/m2, respectively the corresponding figures for the healthy subjects were 51.55 ± 13.39 and 26.26 ± 4.55. The prevalence of calcium deficiency was close in the 2 groups, it being 55.8% in the diabetic, and 57.0% in the healthy, subjects. The data also showed that while 26.3% of the patients suffered from a poor vitamin D status, only 18.6% of the healthy subjects had this problem.
Conclusion: Vitamin D deficiency is highly prevalent among both type-2 diabetic and healthy subjects and should be considered a public health and nutritional problem in Tehran city, Iran.

Abstract
Background and Aim: Female genital mutilation (FGM) comprises all procedures that involve partial or total removal of the external female genitalia for non-medical reasons.The World Health Organization has estimated that 100 to 140 million girls and women worldwide are currently living with the adverse consequences of FGM. Two of the major incentives for FGM are traditions and social pressure, and the practice is mostly carried out by traditional circumcisers. Not only FGM has no health benefits for girls and women, but it has immediate and long-term complications. The objective of this study was to determine the prevalence of female genital mutilation and factors associated with it among women consulting health centers in Ravansar City, Iran
Materials and Methods: A cross-sectional study was conducted on 348 women consulting 5 health centers in Ravansar City, Iran. Data were collected using a structured questionnaire and SPSS.16 was used for data analysis.
Results: The prevalence of FGM was 55.7% and the mean age of the women undergoing FGM was 9.2±14.2 years. The prevalence increased with age. Almost in all cases the operation had been performed by traditional local circumcisers. The data also showed that 96.2% of the mothers and 87.6% of the sisters of the subjects had also been mutilated. There were statistically significant associations between FGM and several independent variables as follows: the mutilated women's age (0.001) and education level (p<0.001) their mothers' education level (p=0.006) and their awareness of, and attitude towards, mutilation (p<0.001).
Conclusion: FGM is prevalent among Ravansar women. Religious leaders and health personnel should attempt to discourage FGM. Promoting public awareness of FGM and its undesirable consequences is essential. Research shows that if a community itself decides to abandon FGM, the practice can be eliminated rapidly.

Abstract
Background and Aim: High fruit and vegetable intake has been introduced as one of the key factors of healthy diet to prevent chronic disease. This study attempts to explore the fruit and vegetable intake in Arak city and its relationship with demography and socio-economic factors.
Materials and Methods : In this cross sectional study, 660 people in 18 -70 age range were selected with a two-stage cluster sampling and were interviewed for demography and socio – economic questionnaires and a 56- items semi-quantitative food frequency questionnaire to assess fruit and vegetable intake. After univariate analysis, the association of the significant variables with fruit and vegetable intake was also evaluated with multiple linear regression.
Results: In this study, over 60 percent of subjects consumed less than the minimum recommended amount of fruit and vegetable (5 servings or 400 gr a day).The total consumption of fruit and vegetable indicated an inverse significant relationship with age (p =0.04 and β = - 0.02), and a direct significant relationship with economic status (p <0.001and β =0.10). The father's educational level (p =0.005 and β =0.38 for diploma level and p =0.03 and β =0.36 for academic education) and physical activity level (p =0.001 and β =0.03 per hour) were factors associated with fruit consumption. The gender was only associated with vegetable consumption so that women had higher consumption in this study (p =0.03 and β=0.23).
Conclusion: The findings of this study indicate low fruit and vegetable consumption in the population under study. In this study, age, physical activity, and socioeconomic status and fathers’ education were the factors that were significantly associated with fruit and vegetable consumption.

Abstract
Background and Aim: In many diagnostic studies, including surveying the survival of patients with gastric cancer where each individual after surgery can experience more than one type of event, and the occurrence of one type of event hinders the occurrence of other types of events, the question of competing risk is raised. For checking the effect of each covariate on the occurrence of any event and estimating the hazard function, Cox and Fine and Gray models are used. In the event that the assumptions of two models do not hold, using them will be an incorrect course of action. One way to overcome this problem is to use models that have higher flexibility.
Materials and Methods: In this study, the demographic, clinical and therapeutic characteristics of 330 patients with gastric cancer who referred from January 1996 to April 2000 to the Cancer Institute of Iran Imam Khomeini Hospital and underwent surgery, including their type, and the time of occurrence of the first event (locoreginal replace/death) for each patient from medical records were collected and evaluated. Using this information, the cumulative hazard function of relapse of disease was plotted by means of three models Cox, Fine and Gray and the flexible one, and was checked against the observed cumulative incidence function of recurrence of disease and, finally, their performance was evaluated.
Results: Nearly, for each event, the proportionality assumption holds for all the variables . According to the graph of cumulative incidence function for the event of interest (recurrence), it can be seen that the Cox model, has overestimated the cumulative incidence function and the curves of two other models are very similar and also similar to the observed curve. However, the cumulative incidence function of the flexible model is smoother than the others.
Conclusion: In the competing risk framework, Cox model is not very useful in practice while it seems that the flexible model is not only a good alternative to the Fine and Gray model but will also be superior to it when the assumption of proportionality does not hold.

Abstract
Objectives: The role of mammography in early detection of b reast cancer is evident and persuasion to do that is very important in health sector. Majority of the interventions are based on education and informing and there has been less attention to making mammography cost beneficent. This study aimed at assessing the effect of a social marketing-based intervention to persuade to do mammography in Bojnord.
Methods: In this quasi-experimental study, two villages around Bojnurd with similar demographic characteristics, considered as intervention and comparison groups randomly. All 35- years and older women consist of 343 women (151 in intervention and 191 in comparison groups) were identified. To obtain the main idea for intervention, and exploring the viewpoints of target group about mammography, a formative research combined of a quantitative survey (through completing the questionnaire for assessing the women’s attitudes based on health belief model) and a qualitative study (through establishing four focus group discussions) was done. According to the gathered and analyzed data, an intervention focused on the main barriers designed and implemented through four weeks. One week after the intervention, the number of mammograms in two villages was determined and compared.
Results: Quantitative survey showed that the mean of the scores related to expending time and high economical costs (perceived barriers) not remember to do mammography and fear of exposure to x- ray is less than other constructs. In qualitative study, time expending and high economical cost considered as two main factors related to not doing mammography. After the intervention, 48.1 percent of the women in intervention group went to do mammography and there are no change similar results in comparison group.
Conclusions: Educational interventions are not enough to persuade women to do mammography and we have to consider their perceived barriers and concerns. One of the most effective approach to promote an idea, behavior or service, is identifying the viewpoints of target group and design them as consumer- oriented programs. So, acceptance of the idea and behavior will be cost-beneficent.

Abstract
Background and Aim: Work ability reflects the interactions among personal characteristics, working conditions, employees' functional capabilities, and also employees' health status. Hence, the aim of the present study was to provide the Farsi version of Work Ability Index and to validate it among Iranian workers.
Materials and Methods: In the first stage, Backward Translation method was used for linguistic validation of the questionnaire. Cross sectional survey of a sample of 645 workers from some Iranian companies were conducted. The study estimated the reliability of the questionnaire by means of test-retest, as well as the construct validity using factor analysis. In order to determine discriminant capacity, the mean scores of different dimensions of work ability index were compared between workers with and without sick leave.
Results: Accordingly, the questionnaire showed a good internal consistency. ICC coefficients for the questionnaire were acceptable. Moreover, factor analyses related to the questionnaire items indicated that only one question is sufficient for each item of "work ability in relation to the demands of the job" and "mental resources". Also, questions related to the item of "number of current diseases diagnosed by physician" can be integrated in six questions. A good level of discriminant validity was observed for all dimensions except for the item of "work ability regarding work demands".
Conclusion: According to the acceptable validity and reliability of Work Ability Index, obtained in the present study, using this questionnaire for evaluating workers' work ability in all Iranian work environments, especially in industrial settings, is recommended.

Abstract
Background and aim: In Iran, HIV prevalence in sex workers is reaching to an epidemic, but still consistent use of condoms is low. This qualitative study aimed to assess barriers to condom use in female sex workers (FSWs).
Materials and Methods: We conducted individual in-depth interviews with 40 FSWs and 12 partners in the year 2010 in Tehran. The FSWs were purposefully selected from four different groups based on the level of socioeconomic status and history of using substance. Findings were extracted and coded manually and the responses of the groups were categorized and compared.
Results: Almost all FSWs had not used condoms regularly in the past six months. The main barriers of condom use were: lack of awareness of the modes of transmission of HIV and prognosis of the disease, doubt on the role of condoms in preventing sexually transmitted diseases and HIV, fear of violence or rejection by male customers, reluctance of sexual partners to use condoms due to diminution of sexual pleasure, and believing in health of some customers.
Conclusions: Increasing awareness of the FSWs through education about HIV, ways to prevent the disease and empowering them on negotiating skills to use condoms as part of harm reduction programs are recommended .

Abstract
Background and Aim: The aim of this study was to assess exposure of workers in a metal industry to nickel and lead.
Materials and Methods: Extraction was done using the solid-phase extraction on Chromosorb-102 resin to prepare, concentrate and purify biological samples of urine, hair and nails of workers working in metal industries. The variables influencing response (pH, loading flow rate, elution solvent, and amount of resins, elution volume, and sample volume) were examined and the procedure was optimized. The optimized procedure was, then, validated based on the “within-day” and “day-to-day” reproducibility experiments, using low, medium and high concentrations, leading to a satisfactory accuracy and precision. Finally, lead and nickel samples were taken from the workers and their concentrations determined voltammetrically.
Results: The optimum values for the examined parameters were as follows: pH = 9, ligand concentration = 0.05%, loading flow rate = 5 ml/min, elution solvent = 2M HNO3, amount of resins = 500 mg, elution volume = 15 ml, and sample volume up to 500 ml. A good reproducibility and repeatability was obtained for the optimized method under the existing conditions. Lead and nickel could be extracted with recoveries in the range of 94-100%. On the whole, the concentrations of nickel and lead in the workers’ biological samples were above the respective maximum permitted levels.
Conclusion: Solid-phase extraction procedure is a fast and simple method for preconcentrating and isolating analytes from biological samples. Considering the low concentrations of the analytes and presence of confounding factors in such samples, the procedure can be very effective for their preparation. The application of the developed method indicates that trace metal ions can be effectively purified and preconcentrated from different matrices like urine, hair and nail samples to assess occupational exposures.

Abstract
Background and Aim: A New Health Reform Plan consisting of seven programs was initiated in Iran in mid-May 2015 aiming to reduce the out-of-pocket payments, improve the public’s health, and promote the public health indicators. This study was conducted to determine the effect of the Plan on the performance indicators of Hamedan university hospitals.
Materials and Methods: In this longitudinal descriptive-analytical study, based on the interrupted time series design, data related to hospital performance indicators were collected from all (15) Hamedan University hospitals for a period of 15 months (7 months before, and 7 months after, the implementation of the Plan, with a one-month interval in between). The SPSS software was used for data analysis.
Results: The data indicated changes in all the performance indicators after the implementation of the Plan. The largest changes were in the number of emergency and selective surgeries and the smallest in the ratio of active to total beds. Further analysis of the data showed that, as compared to the same months in the previous year, only a small number of these changes (number of emergency surgical operations and the ratio of active to total beds) were statistically significant.
Conclusion: Based on the findings it can be concluded that changes have occurred in all the selected indicators as a result of implementation of the New Reform Plan, indicating that the Plan has affected favorably performance of the hospitals. However, the effects observed should be judged cautiously, considering the possible negative consequences such as induced demand and hospital workload increase in the long run.

Abstract
Background and Aim: Human resources in any organization are its main capital. They are the only unique asset that are not liable to depreciation over time, but they even create more added value. The Social Security Organization (SCO) as a social insurer organization needs urgent assessment of its human resource management. In this regard, it appears that such an essential assessment can be done using the European Foundation for Quality Management (EFQM) model.
Materials and Methods: This project was an applied descriptive study conducted at the Social Security General Department in Tehran, Iran. The data collection tool was a standard questionnaire for performance assessment based on the EFQM model, the reliability of which (0.989) was determined by using the Cronbach's alpha coefficient. A total of 388 questionnaires were distributed, of which 311 were completed and returned to the researcher; the response rate was 81%. Analysis of the data was done using the SPSS-16 software.
Results: The human resource managers in the SCO achieved a score of 495.72. The empowerment and results dimensions rated 261.34 and 198.38, respectively. In the empowerment dimension, policy and strategy criteria had the highest score (56.12) and process the lowest (51.28), while in the results dimension, community criteria had the highest (50.27) and the customers criteria the lowest (51.18) score.
Conclusion: Based on the findings it can be concluded that the European Foundation for Quality Management (EFQM) model is suitable for assessing both the performance, strengths and weaknesses of the Tehran Security General Department human resources and improving its performance. Certainly better implementation of programs and achieving excellence will be possible through sustainable collaboration.

Abstract
Background and Aim: Sexuality education is one of the most important educational needs of adolescents, and mothers can have a key role in sex education of their daughters. This study aimed at developing, implementing and evaluating a skill-based training program for mothers for sexuality education of adolescent girls in Mahshahr, Iran.
Materials and Methods: This was a field trial conducted on 140 mothers having 12- to18-year-old girls between September and March 2012. Data were collected using two reliable questionnaires developed by the investigators ─ a "Parent-Child Relationship: Mother" questionnaire for assessing the mothers’ communication skills completed by the adolescent girls, and a "Knowledge and attitude about sexuality education of adolescents" questionnaire for assessing the mothers’ knowledge and attitude about sex matters and communication, skills completed by the mothers themselves. Based on the results, an educational intervention for mothers was designed consisting of three training sessions and implemented. The mothers’ knowledge, attitude and communication scores after a period of three months were compared with the respective baseline scores.
Results: Three months after the intervention, the mean scores of mothers’ knowledge and attitude about sexuality matters increased significantly (in both cases p <0.01). However, there was no statistically significant difference between the initial and final scores of mothers’ communication skills (p = 0.37).
Conclusion: Based on the findings it can be concluded that the designed educational program was effective in improving the knowledge and attitudes of the mother about sexuality matters although it did not affect their communication skills. Promoting communication skills of mothers as an important factor for sexuality education of their daughters requires regular, continuous educational sessions, as well as practice and experiences.

Abstract
Background and Aim: Hospital accreditation is a systematic external evaluation of a hospital’s structures, processes and results (outputs/ outcome) by an independent professional accreditation body using pre-established optimum standards. This study aimed to examine the relationship between accreditation and hospital performance. In addition, the most important accreditation constructs affecting hospital performance were identified and ranked.
Materials and Methods: This descriptive, correlational and cross-sectional study was conducted using the data related to accreditation scores and nine performance indicators of 121 hospitals in 2014 and 123 hospitals in 2015 in Tehran province, Iran. Shannon entropy method was used for calculating the weights of the hospital indicators. Then, Feature Selection method in data mining was used to explore the relationship between accreditation scores and hospital indicators. Data were analyzed using IBM SPSS Modeler software. Analyses were carried out at the 0.05 significance level
Results: The mean of hospitals’ accreditation scores were 61.98% and 69.56% in 2014 and 2015 respectively. All performance indicators except the number of outpatients were increased in 2015 compared to 2014. There was no significant difference in the scores between 2014 and 2015 data. Hospitals’ accreditation scores were not associated with their performances. However, accreditation scores of leadership and management; accident and emergency; and procurement departments had the most effect on hospitals’ performance.
Conclusion: Accreditation was not correlated with hospital performance. Thus, improving accreditation system including standards, methods and surveyors and using quality management strategies in hospitals are necessary for improving hospital’ performance.
