Abstract
Background and Aim: This study aimed to determine dietary patterns in district 13 of Tehrani adults and evaluate its association with socio-demographic and lifestyle factors
Materials and Methods: This cross-sectional study was conducted on 343 male and 453 female aged 18-65 years who participated in Tehran Lipid and Glucose study. Usual dietary intakes were assessed with food frequency questionnaire. Dietary patterns were determined by factor analysis based on 24 food groups identified by similarity of nutrients. Three major dietary patterns were identified: healthy (HDP), western (WDP) and traditional (TDP). Lifestyle and socio-demographic characteristics gathered with pre-tested questionnaires. Multiple regression models separately for men and women were fitted to assess the relationships.
Results:The mean age(SD) of men and women were 40(13) and 36(12) respectively. WDP characterized by a higher consumption of salty snacks, sauces, sweetened beverages, processed meats and refined grains, and the HDP characterized by greater intakes of vegetables, low fat meats, tea and coffee, legumes and nuts.WDP had the most variance among 3 dietary patterns. The mean factor score of HDP was higher in women than in men(P<0.05) after adjusting for age and total energy intake. Adherence to a WDP was higher among younger participants (men: β=-0.46, women:-0.34, P<0.001). The percent of married individuals were the most in fourth quartiles of HDP score among the other quartiles (P<0.01) and married men were less likely to follow WDP (β=-0.25, P<0.01).
Conclusion:Three major dietary patterns were found with factor analysis: western, healthy and traditional. Younger and single individuals had more adherence to WDP and women had higher score in HDP.

Abstract
Background and Aim: In the initial preparation stage, before feeding worms with organic wastes, the wastes are pre-composted for some time. This was done so that the thermophilic phase of organic wastes degradation is passed, no harm is done to the worms which are sensitive to high temperatures, production of fertilizer faster is quicker, and biological contamination is reduced. The length of this preparation time is important with regard to the quality of the compost obtained, the vermicomposting process, and space and facilities needed. The purpose of this study was to determine the effect of preparation time of food wastes on the vermicomposting process without any preliminary action or continuous aeration.
Materials and Methods: The Eisenia Foetida species was used for vermicomposting. Food waste preparation times of 0,6,12 and 18 days were attempted, and factors such as pH, C%, N%, C/N ratio, and the process rate were monitored during the process.
Results: The lowest and highest final C/N ratios were seen on days 6 and 18 of preparation, respectively. The data also showed that the highest reduction (64.93) in this ratio was observed on 6 day and the lowest (36.56) on day18.
Conclusion: On the basis of these findings it can be concluded that there is a significant difference among various food waste preparation times with regard to C/N ratio (p-value<0.05), the preparation time is effective on the C/N ratio, and the most appropriate length of time for preparation is 6-12 days.

Abstract
Background and Aim: The hospital is considered as the biggest and the most costly unit of a health care system. Therefore, paying full attention to its cost efficiency is very important. The objective of this study was to assess the technical efficiency of hospitals affiliated with Tehran University of Medical Science by data envelopment analysis method.
Materials and Methods: Technical efficiency in hospitals affiliated with Tehran University of Medical Sciences was assessed by Data Envelopment Analysis (DEA) from 1996 to 2006. The input-oriented form of variable return-to-scale (VRS) was used to collect the data using 4 inputs (number of beds, nursing staff, medical personnel, and other personnel) and 4 outputs (outpatient admissions, hospitalized-patient days, bed occupations, and the number of surgical operations performed). The software used for data analysis was Deap 2.1.
Results: The DEA results indicate that: 1.There is a potential to improve the hospital technical efficiency by 3 % (the mean technical efficiency of the hospitals was 0.972) 2. Constant return-to-scale (CRS) exists in the production process, meaning that production in the hospitals is at its optimum level 3. Hospital services have suffered from extra production factors, especially human resources (specifically the nursing staff).
Conclusion: With proper planning, limiting the number of personnel can reduce greatly health care costs and hospital expenditures. It is suggested to conduct studies to determine the effects of the quality of services delivered in hospitals and patient satisfaction on hospital technical efficiency.

Abstract
Background and Aim: Rapid growth of Iran's population attracted attention of the authorities after the 1986 national census. This led to population control and family planning programs to be considered as a priority. Appropriate strategies of the family planning program led to a very fast decrease in population growth and fertility indices: and use of contraceptive techniquies rate increased from 49% in 1989 to 73.8% in 2007. This study aimed at reviewing family planning program in Iran (FPPI) during the last four decades and discussing the reasons for its success, as it can be a guide for future efforts aimed at improving other aspects of reproductive health.
Materials and Methods: The method used was systematic reviewing of articles indexed in Medline and University Jihad Scientific Database, reports of the Demographic and Health Project, the Iranian Statistical Center National Censuses, and the Ministry of Health and Medical Education reports on knowledge, attitude and practice.
Results: FPPI initiated officially in 1966 faced with limited success. Following the 1986 national census, population control was announced as a public policy, supported by the leaders. A supportive environment was created by mass media. Establishment of the Departments of Population and FP in the Ministry of Health made possible reorganizing family planning services: expanding coverage of PHC services, including FP services training skilled personnel providing free contraceptives and vasectomy and tubectomy services. Involvement of volunteers and NGOs helped in strengthening community actions. In order to develop personal skills, in addition to face-to-face FP counseling in the health centers, FP education in schools, colleges, workplaces, army and pre-marriage classes was also imparted. Promotion of men's participation in FPPI, by providing male methods of contraception, such as vasectomy or condom use, was also considered. There was also cooperation and support on the part of nongovernmental and international organizations.
Conclusion: Based on the findings, it may be concluded that the principles of health promotion can explain the FPP achievements in Iran. This model can be used in expanding other reproductive health programs in 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: Considering the social and cultural characteristics of Iranian adolescents, none of the quantitative instruments designed so far to assess their health needs is quite appropriate. The purpose of this study was to design a valid and reliable questionnaire to assess the health needs of Iranian adolescent females.
Materials and Methods: Both qualitative and quantitative approaches to instrument development were adopted in this study conducted in the District of Sari in the north of Iran. Sampling was objective-based, with an attempt to have female adolescent sample as varied as possible. In the qualitative phase, a content analysis approach was used to explore the concept of health needs as seen by female adolescents. Data were collected using 8 focus group discussions (FGDs) with the presence 6-10 adolescents 12-18 years old in each FGD, as well as 11 semi-structured interviews, each one involving 11 well-informed individuals. In the quantitative phase, the psychometric properties, including content validity, face validity, construct validity, concurrent validity, internal consistency, and test-retest reliability, were determined.
Results: Five themes were identified in the qualitative phase of study, including psycho-emotional health, social health, physical health, and educational needs, as well as spiritual beliefs. The mean scale-level content validity index (S-CVI) was found to be 0.92. The factor structure of the instrument was identified by doing a Principal Component Analysis. Five factors were extracted with a total variance account of 45.37%. The reliability and consistency of the instrument were established with the Cronbach's alpha coefficient (0.90) for the entire scale and test-retest reliability with a 2 week-interval Intraclass Correlation Coefficient (ICC=0.984, p<0.001).There was a concurrent correlation between the instrument and Pediatric Quality of Life Inventory (PedsQL TM 4.0) (r=0.66, p<0.001).
Conclusion: The instrument developed in this study is a valid, reliable and culturally appropriate instrument for assessment of health needs of Iranian adolescent females.

Abstract
Background and Aim: Breast and cervical cancer screening is considered a health promotion behavior, influenced by complex factors. The theory of planned behavior provides a useful framework for predicting and understanding the health behavior and designing appropriate educational interventions. Integrating this theory with self-efficacy will increase its predictive value. The objective of this qualitative research project was to understand the factors influencing the behavior of breast and cervical cancer screening of female-workers as a base for future educational planning.
Materials and Methods: This was a qualitative approach research based on the Integrated Model of Planned Behavior and Self-Efficacy. Seventy 20-45 year-old women working in industrial plants in Abbasabad, Pakdasht, selected by purposeful sampling with maximum diversity participated, in 10 groups of 7 each, in focus-group discussions, in which they discussed their experience regarding factors influencing the behavior of breast and cervical cancer screening. Data were collected and their validity, conformability, transferability and dependability confirmed. For data analysis the conventional method of content analysis was used.
Results: The female workers had a low knowledge and attitude concerning the behavior of breast and cervical cancer screening. Attaching importance to comments given by the family members, especially the husband, and preference of treatment to prevention of disease in the society at large were the subjective norms of the female workers. The most important barriers to participating in screening programs were lack of knowledge, depression, fatigue, embarrassment and fear of examinations, fear of being sick, poor quality of services and lack of attention to privacy in health centers, limited access to health centers, and costs of tests. The female workers had a low self-efficacy for planning and overcoming barriers. Most of them had not had screening tests and had no intention of doing their screening tests in the following three month.
Conclusion: The following measures are recommended: designing and implementing specific educational programs in workplaces for female-workers aiming at increasing their awareness and positive attitudes towards breast and cervical cancer screening designing and implementing educational/training programs for families, employers and planners to increase their knowledge and attitude and facilitating women's access to health centers in industrial estates.

Abstract
Background and Aim: Demographic, physical, social and psychological factors make breastfeeding and its maintenance complex. Despite extensive breastfeeding promotion programs, no progress has been achieved. As breastfeeding is a phenomenon embedded in culture and folk perceptions, identification of its key determinants is essential when designing policies and implementing programs.
Materials and Methods: In this qualitative study, data were collected from 35 health professionals through a 4-day group interview using a structured questionnaire (open-end questions). The participants were purposefully recruited from among the health professionals attending a 4-day breastfeeding promotion workshop.
Results: The determinants of breastfeeding were categorized into 2 main domains, namely, people's perception of breastfeeding phenomenon and approaches employed in its promotion. The former domain was described by beliefs, demographic characteristics, social variables, and indigenous theories, and the later by practice in the cultural and social context, policies, interactions and practical skills.
Conclusion: From the participants' perspective, misperceptions of people can determine the degree of success or failure of a breastfeeding promotion program. Our findings confirm that people's perceptions are deeply influenced by their demographic characteristics, folk theories and social variables. As regards the breastfeeding promotion domain, the barriers are social-cultural factors rooted in the local beliefs and folk theories. The participants listed the breastfeeding promotion determinants as lactation policies and health providers' performance related to their skill in effective communication with mothers. Our findings also indicate that wrong beliefs, maternal and child diseases, caesarian section, and mothers' employment were believed to be deterrents in promoting breastfeeding in the community and that pediatricians, obstetricians and other health professionals can play key roles in the field. Based on our findings, we can further conclude that the phenomenon of breastfeeding and its maintenance are deep-rooted in social structure and cultural diversity. When designing and implementing breastfeeding promotion programs, local variables and determinants should be taken into consideration.

Abstract
Background and Aim: Iran National Polio Laboratory (NPL) is a member of the World Health Organization (WHO) Polio Laboratories Network. NPL receives stool specimens from acute flaccid paralysis (AFP) cases from all the provinces throughout Iran for poliovirus detection and identification. Furthermore, the NPL also detects non-polio enteroviruses (NPEVs) in these specimens. Recently, NPEVs have come to be believed to be one of the most important causes of AFP following wild poliovirus. This paper reports the prevalence of different types of NPEVs isolated from the specimens of AFP cases between 1995 and 2000.
Materials and Methods: Stool collection, virus detection and serotype identification were performed according to the WHO standard procedures.
Results: A total of 2180 stool specimens from AFP cases were received at the National Polio Laboratory. Coxsackie B viruse and echoviruses 6, 11, 7 and 13 had the highest frequency, identified in 23.7%, 14.4%, 12.7%, 11% and 10.2% of the NPEVs isolated from AFP cases, respectively. Four cases of echovirus 20 were identified, in 2 cases the patiets having died and in one the patient having been afflicted with residual paralysis. There have been no reports of death or residual paralysis (paralysis continuing after 60 days) due to echoviruse 20.
Conclusion: Considering the upward trend of AFP cases in Iran, even after wild poliovirus eradication, studies are needed to determine the frequency and type identification of NPEVs and the relationship between NPEVs and residual paralysis in the post-eradication era (2000 onwards).

Abstract
Background and Aim: To examine the association of diet and the risk of esophageal squamous cell carcinoma (SCC) in Kurdistan province.
Materials and Methods: This was a case-control study including 47 patients with esophageal SCC and 96 healthy controls. Dietary intake was assessed using a valid semi-quantitative food frequency questionnaire. Logistic regression analysis was run to estimate odds ratios and 95% confidence intervals.
Results: The controls had a significantly higher mean body mass index (25.3 vs. 20.4) and a higher level of education than the case group, while the latter had significantly higher records of tobacco consumption and symptomatic gastresophageal reflux. An independent protective effect was observed for the highest tertile of total fruit consumption (OR: 0.13, CI: 0.04-0.45, p-value=0.001). Within the fruits group, a significant inverse association was observed for bananas, kiwis and oranges (P for trends: 0.03, 0.02 and 0.01, respectively). The effect of total vegetable intake on esophageal SCC was not significant (OR: 0.66, CI: 0.23-1.87), although a reduction in risk was observed in the highest tertile of intake. With regard to other food groups we did not find a statistically significant association.
Conclusion: The results of the present study suggest an inverse association only between fruit consumption and esophageal SCC.

Abstract
Background and Aim: Access to reproductive health information and services is a basic right for the youth. Lack of suitable educational/counselling materials about reproductive health can decrease effectiveness of educational programs. This study aimed to determine the premarrital reproductive health educational needs of the youth.
Materials and Methods: In a descriptive-analytical study a total of 450 young males and females were selected by stratified random sampling to participate in pre-marital counseling in Tehran. Data about pre-marrital reproductive health educational needs were collected using a questionnaire developed by the investigator, with a 5 degree-Likert scale. SPSS-15 was used for data analysis, the statistical tests being t-test, one-tailed ANOVA and chi-square.
Results: Based on the Likert scale (1-5), felt need for reproductive health education was 3, it being higher among females (p<0.05). Both the males and females thought that what they needed most was education/counseling on healthy sexual relationship. The educational needs did not seem to be influenced statistically significantly by socio-demographic variables in either gender.
Conclusion: Based on the results of this study, it seems that the current educational materials are not sufficient for pre-marrital counseling. Comprehensive information on reproductive health, with particular emphasis on sexual relationship, should be included in the existing programs, so that the youth can begin a better, healthier married life.

Abstract
Background and Aim: Urinary Incontinence (UI) as a main health problem affects on Quality of Life negatively. UI prevalence is reported between 3-57.1% in different countries. Nevertheless, there are limited studies about probable risk factors, e.g. type and number of delivery and related disorders such as anal incontinence. This study was aimed to investigate the UI risk factors and related disorders in our society.
Materials and Methods : A cross-sectional study was conducted on 166 women with UI and 90 healthy subjects, aged 26-70(45.3±7.9) and 20-64(38.2±8.4) years respectively. After completing a designed questionnaire, assessment of vaginal tone, Pelvic Floor Muscles'(PFM) strength and endurance carried out. Independent t-test and Pearson correlation test were used to analysis the data. Values of p<0.05 were considered to be significant.
Results: Our data showed that the mean of age, Body Mass Index (BMI) and number of deliveries in women with UI were significantly higher than that women without UI were (P<0.05).There was a significant difference regarding to the prevalence of anal incontinence and constipation between two groups (P<0.05). Reduced vaginal tone and lower strength and endurance of PFM were seen in women with UI (P<0.05).
Conclusions: Regarding high prevalence of some pelvic floor disorders such as constipation in incontinent women, we recommend performing further epidemiologic and etiologic investigations , also emphasis on establishing multidisciplinary approach health/therapeutic centers to provide better services to these patients.

Abstract
Background and Aim: There is some evidence that nutrition probably plays a role in the etiology of multiple sclerosis (MS). The present case-control study was conducted in the City of Tehran, Iran with the purpose of finding any possible relations between food groups and MS.
Materials and Methods: In this case-control hospital-based study conducted in 2011 in the City of Tehran, data were collected on several variables including socio-economic status, life style, and food intakes of 70 MS patients and 140 controls matched for age and gender, through interviews and questionnaires. All the statistical tests were done using the SPSS software version 16. Logistic regression was used to calculate the odds ratio (OR).
Results: After adjusting for confounding variables, it was seen that subjects in the upper tertile of intakes of the fruit group, tomatoes, other vegetables, and liquid oils, were significantly less likely to be suffering from MS disease, the odds ratio being 68% (OR: 0.32 95% CI: 0.13-0.79), 82% (OR: 0.18 95% CI: 0.05-0.65), 61% (OR: 0.39 95% CI: 0.93-0.16), and 94% (OR: 0.06 95% CI: 0.08-0.58), respectively. On the other hand, subjects shown to be significantly less at risk of the disease were those in the upper tertile of the intakes of non-liquid oil [ 1.58 times (OR: 2.58 95% CI: 1.05-6.33) ] and soft drinks [1.87 times (OR: 2.87 95% CI: 1.17-7.02)] (p for trend < 0.05).
Conclusion: The findings of this study support the probable role of nutrition in preventing multiple sclerosis.

Abstract
Background and Aim: Human T-Cell Lymphotropic Virus (Type I) is the cause of two major diseases : Adult T cell Leukemia-Lymphoma and Tropical Spastic Paraparasia and Myelopathy associated with HTLV-I. Disease transmission is possible during unsafe sexual contact, blood transfusion and vertical transmission method. Blood safety and minimizing the risk of transfusion transmitted infections are the main goals of blood transfusion organization. Mashhad is located in an endemic area and it is essential to investigate about the virus epidemiology.
Materials and Methods: In this descriptive study from 1388 to 1389. all the blood donation volunteers, who were eligible for blood donation but had HTLV serum positive results in both screening and confirmatory tests with Elisa and Western Blot method, respectively, were considered as HTLV infected individuals. The infected group was compared with a group of healthy blood donors as a witness group. The data were analyzed by SPSS-17 software.
Results: Out of all 432 infected donors, 353(% 81.7) were male and 79 (% 18.3) were female. The prevalence rate in two years of study was %0.26 and %0.25 Respectively . There was a significant relation between age, sex, marital status, education levels and history of blood donation with HTLV-1 seropositivity.
Conclusions: Because of the improvements in donor screening and laboratory methods , the prevalence of HTLV-1 infection among blood donors has currently decreased. According to the low rate of infection among younger blood donors, regular blood donors and donors with higher educational levels ,it should be considered to select donors from these groups.

Abstract
Background: Sexually transmitted infections are one of the most prevalent infections all over the world that impose significant morbidity on people. There are an increasing number of sexually transmitted infections in Islamic Republic of Iran during recent years. So developing and implementing programs for STIs prevention and control is considered as a health priority. While the role of gender based power in sexual relationships has in recent years been acknowledged, the understanding has largely lacked practical considerations in the STIs/HIV/AIDS prevention fields. This study aims to explore gender sensitive STIs/HIV/AIDS prevention services concepts and dimensions.
Method : This study employed content analyzes research design. Semi-structured in-depth interviews were conducted with 37 expert reproductive health managers and providers that selected purposively and then continued by snow ball method. Data collected by using semi-structured interview guide. The interviews were transcribed and typed. Data was analyzed according to content analysis.
Results: 2 categories emerged as the result of data content analysis: 1) gender sensitive structure including employers, facilities and management dimensions 2) gender sensitive process including care and educational processes.
Conclusion: providing gender sensitive STIs/HIV/AIDS prevention services need gender sensitive management, facilities and providers and gender sensitive care and educational design.

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 role of nutritional quality of the diet in the development and progression of multiple sclerosis (MS) is not yet well understood. The aim of the present study was to determine the association between index of nutritional quality (INQ) and MS.
Materials and Methods: In this case-control study, 70 patients with a definitive diagnosis of MS in the preceding year and 140 frequency-matched hospital controls were selected from among 20-50 year-old patients referred to Sina and Lolagar hospitals in Tehran. The subjects’ dietary intakes were assessed using a valid and reliable semi-quantitative food frequency questionnaire. INQs for all the nutrients were then calculated for every participant, and logistic regression analysis was used to calculate the odds ratios for having MS in relation to every nutrient’s INQ.
Results: After adjusting for potential confounders, it was seen that subjects who had higher INQs for alpha-linolenic acid, vitamins A, D, K, B1, B2, B5, B6, folate, B12, and C, and minerals calcium, phosphorus, zinc, and potassium were less likely (p<0.05) to have MS as compared to subjects with lower INQs for these nutrients.
Conclusion: The findings of the present study show inverse associations between the INQ of many nutrients and risk of having MS. Therefore, it seems that overall improvement of the nutritional quality of the diet might be an appropriate approach for prevention of this disease.

Abstract
Background an Aim: Community-based health promotion program encompasses actions aiming at enabling individuals, organizations and communities for enhancing behaviors and creating a healthier environment. Considerable experiences regarding community health promotion and community-based health promotion exists in Iran, but they have not been documented adequately.
Materials and Methods: This paper reports some of the findings of a situation assessment project of community-based health promotion programs in Iran, including typology of community-based health promotion programs and critical analysis of challenges and threats, discussing potential opportunities to improve community-based health interventions. All the available reports, official documents, information and published papers related to community-based health promotion programs implemented in Iran were examined.
Results: The majority of health-related interventions excluding three national programs, namely, the volunteers, community health workers (Behvarzes) and polio eradication programs, were categorized in three large groups ─ community-based initiatives, community-based participatory research, and community-based addiction prevention. Many of these programs were not community-based in the true sense of the word.
Conclusion: The findings indicate that in Iran, unlike many other countries, the majority of the interventions are initiated and implemented at the national level with good organizational support. Although implementation of such programs is generally considered feasible in Iran, it seems that the available opportunities have not been adequately exploited for their implementation.

Abstract
Background an d Aim : Several factors can affect the sexual function of women. The aim of this study was to determine the correlation between exercise and sexual function in post-menopausal women.
Materials and Methods : This was a community-based, descriptive-analytical study including 405 post-menopausal women 40-65 years old selected by multi-stage stratified random sampling . The data were obtained through interviews using the Female Sexual Function Index (FSFI) and a researcher-made questionnaire. The data were analyzed using descriptive and analytical tests such as multiple linear regression and logistic regression models .
Results : On the whole, 61% of the subjects had sexual dysfunction. The most common type of exercise was “walking” (79.8%). For the women who exercised, the mean score in the domain of pain was significantly lower (worse) (p=0.013). The total FSFI, lubrication and pain domains scores were significantly lower in the women who did exercises other than walking as compared to those who did not exercise or practiced only walking. The weekly exercise frequency had positive correlations with lubrication (r=0.18, p=0.014) and orgasm (r=0.146, p=0.045) domain scores.
