Abstract
Background & Objectives: Ecstasy is a methamphetamine derivative becoming increasingly popular throughout the world, particularly among adolescents and young adults. Iran, situated between eastern and western societies, can serve as a significant source of information on ecstasy use and on the users' profile. The purpose of this study was to determine the prevalence of ecstasy use and high-risk behavior among high school students in Lahidjan.
Methods: We conducted a cross-sectional study of a representative sample drawn from high school students of Lahidjan in 2005, using multi-stage stratified random sampling. The study questionnaire was administered to 2345 students in grades 8 through 12. The questionnaire was adapted from that used in "Monitoring the future" projects in the United States and ESPAD (The European School Survey Project on Alcohol and other Drugs). It included questions on demographic characteristics, family profile, social contacts, school life and the use of drugs. Data analysis was done with the SPSS software (version11.5), using χ2 tests and logistic regression methods.
Results: Of the 2345 students selected for the study, 2328 (92%) responded. Of these, 1327 (57.8%) were males and 970 (42.2%) were females. Lifetime prevalence of ecstasy use was 2.4% (55 students) 31 subjects had used ecstasy within the past month and 24 students reported using the substance in the preceding year. Ninety-two subjects (4.2%) had experience with other drugs. In χ2 tests, ecstasy use was significantly associated with gender, use of other substances, cigarette smoking, partying with friends, family structure and poor school performance in the past. There was no association with age, type of school (private or public) or the family's education level.
In logistic regression, factors influencing ecstasy use were the use of other drugs, cigarette smoking and partying with friends (p< 0.0001).
Conclusions: Ecstasy use appears to be a serious problem in high schools. Whatever the causes behind the rise in ecstasy use, personalized and informative educational interventions should be organized in all schools.

Abstract
Background & Objectives: Iron is a major essential micronutrient during pregnancy and has an important role in intrauterine fetal growth and safe delivery. This survey was designed to study the status of anemia, iron deficiency and iron deficiency anemia in pregnant Iranian women. The results can help health policy-makers with the design and implementation of targeted strategies to overcome these problems.
Methods: This cross-sectional study involved 4368 women at gestational ages ranging from 6 to 9 months. Subjects were drawn through cluster sampling from 11 different regions of the country. Hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV) and serum ferritin levels were measured and the prevalence of anemia, iron deficiency and iron deficiency anemia (IDA) was determined both nationwide and separately in each region.
Results: Overall, 21.5% of the women suffered from anemia 42.7% were iron deficient and the prevalence of IDA was found to be 10.4%. The prevalence of anemia s was significantly greater in rural areas than in urban settings (22.2- 27.8% compared to 17.1 -21.6%, 95%CI). The highest prevalence of anemia and low Hct was seen in the women of region 5 (including Sistan and Baluchistan, South Kerman and South Khorasan with rates of 44.2% and 40.5% respectively). Region 6 (covering Isfahan, Yazd, Kohkilooyeh-Boyerahmad and North Kerman) had the lowest prevalence of anemia and low Hct (9% and 10.8% respectively). Use of iron supplements (even irregular) had a positive effect in reducing anemia. It affected Hct levels only when taken regularly.
Conclusions: Anemia is still a major health issue for pregnant Iranian women. Although supplementation should be continued, there is a need for more comprehensive interventions addressing all target groups, especially women of child-bearing age.

Abstract
Background & Objectives: Recent evidence suggests that long-term exposure to air pollution contributes to progression of atherosclerosis and the risk of cardiac morbidity and mortality short-term exposure may also lead to thrombosis and acute ischemic events. To evaluate the relation between the levels of major air pollutants (CO and PM10) and hospital admission for acute coronary syndrome (ACS) in Tehran, we performed a case-crossover design and checked whether individual characteristics act as effect modifiers.
Methods: We selected 250 Tehran residents who had been hospitalized with an acute coronary syndrome from 4th of April to 10th of June, 2007. The following individual data were gathered: sex, age, date of hospitalization, and coexisting illnesses (hypertension, diabetes). Daily air pollution data were taken from the Air Quality Control Center. Temperature, humidity, stress, physical activity and weekend days were treated as confounding variables, and a conditional logistic regression model was used for statistical analysis.
Results: We found a positive association between ACS and average 24-hour CO levels. The OR for each unit increase of the average 24-hour CO was 1.18 (95%CI: 1.03-1.34). The relation between ACS and 24-hour average PM10 did not reach statistical significance (OR for average 24-hour PM10 was 1.005, 95%CI: 0.99-1.01). The association between ACS and 24-hour average CO tended to be stronger in women (OR=1.68 for each unit increase, 95%CI: 1.25-2.26). The relation between 24-hour average PM10 and ACS did not change across the layers of the effect modifiers.
Conclusions: The results suggest that an increase in average 24-hour CO levels will augment the risk of ACS, and the effect is stronger in females. On the other hand, we were unable to document an association between ACS and average 24-hour PM10 levels.

Abstract
Background & Objective: Malnutrition is one of the main nutritional problems among children under 5 years especially in developing countries. The effects of malnutrition in this range of age group includes disorder of mental and physical growth and development, increase in the morbidity and mortality, decrease of the learning capacity. A detailed epidemiological picture of the prevalent malnutrition status among children under 5 years in different regions of Iran enables health policy makers to identify priorities, establish political commitment and design appropriate interventional programs to prevent and control malnutrition and improve nutritional status of children. To determine the prevalence rate of malnutrition among children under 5 years.
Methods: Demographic data, weight and height of 34200 Iranian children between 0-72 months old in 28 provinces of the country in 2005 year based on a cluster sampling were gathered. The subjects' weight and height were measured by trained staff. Prevalence of underweight, stunting, and wasting indicators was determined by measuring the weight and height of subjects in urban and rural areas. EPI6 statistical software, version b6/04, was used for all statistical analyses.
Results: 4.7% of the children aged less than five years suffered from stunting (95% CI: 4.5- 4.9%) The prevalence of this type of malnutrition among urban children is significantly less than rural children (95% CI: 3.1- 3.5% and 6.5-7.1% respectively). Meanwhile the prevalence of underweight was 5.2% in the country (95% CI: 5.1-5.4% while the prevalence of this type of malnutrition was significantly less among urban children than those in rural ones. Moreover, the prevalence of wasting was 3.7% (95%CI: 3.5-3.9%) and there was a significant difference in this regard between the urban and rural children. Thus this indicator was significantly higher among urban children than those in rural areas (95%CI: 3.8-4.3% and 3.0-3.5% respectively).
Conclusion: The results of the study show that the prevalence of protein-energy malnutrition was low among Iranian children under five years old. In comparison with previous studies, it is felt that there has been a prudent decrease in all malnutrition in all levels. However, there were significant differences in the prevalence of malnutrition in different provinces, which has resulted in the differences in their developmental stages as well. It appears that subjective strategies are required to improve the nutritional and health status among children under five in all provinces.

Abstract
Background & Objective: the number of people with HIV/AIDS in Iran is increasing. Populations' knowledge and awareness are crucial steps to prevent HIV/AIDS epidemic. This systematic review aimed to assess the level of knowledge and attitude toward HIV/AIDS in Iranian population.
Methods: Reviewing related titles in national and international databanks resulted in 62 eligible studies published between 1998 and 2008. To explore the source(s) of heterogeneity, meta-regression model was used.
Results: Due to the methodological diversity of included studies (e.g. their sampling or data collection methods) pooled estimation of the results were hard to be applied. The mean for knowledge score among 24 eligible studies (including 24,011 individuals) varied between 14.7 and 84.0 out of 100. Among those 16 eligible studies (including 11,104 individuals), the reported mean for attitude varied between 32.6 and 78.4 out of 100.
Conclusion: In overall, it seems that the knowledge and attitude in Iranian population still need to be improved however, the results from our systematic review showed a considerable heterogeneity among the results that can be originated from the diversity of target populations and/or their methodology of included studies. Planning for further targeted programs and modifying public education for more effective schemes are necessary to be emphasized, as there was not a significant change in the level of knowledge or attitude based on the included studies.

Abstract
Background and Objectives: Data plays a major role in a health care system in development planning and health services support if they are correct, timely and accessible. The data of the Ministry of Health are not readily available and the limited access reduces their value. The aim of this study was to explore the challenges of access to the data of the Iranian Ministry of Health.
Methods: This qualitative study was conducted in 2015. Twenty-three academic and administrative experts were selected purposefully. Semi-structured interviews were conducted to collect the data. The transcripts of the interviews were analyzed using content analysis.
Results: The results of this study provided 4 main themes (challenges of access to the data of the surveillance system, challenges of access to the data of national surveys and ordered projects, challenges of access to the data of electronic health records, and challenges of access to confidential data) and 15 sub-themes.
Conclusion: Given the multiple challenges of access to the data of the Iranian Ministry of Health, it is suggested to design access mechanisms in a systematic manner in the form of guidelines and organizational structures for data access management.

Abstract
Background and Objectives: People living with HIV (PLHIV) experience severe psychological pressure in most communities; however, this pressure is more prominent in women. Therefore, it is very important to monitor different aspect of psychological pressure and psychosocial supports in this group of patients. Based on this need, in this study, we assessed the status of mental health, hope, and social support in female PLHIVs visiting health centers of Kerman, Iran.
Methods: In a triangulation study comprising a combination of qualitative and quantitative components, PLHIV women were recruited and their information were collected using Goldberg’s General Health Questionnaire, Sarason’s Social Support Questionnaire, and the Miller’s Hope Scale.
Results: Our findings showed that female patients’ status improved markedly after visiting the health centers (hope: 92%, general health: 80%, social support: 93%). In addition, the results showed a strong positive the correlation between general health and hope (r=0.61, P<0.0001).
Conclusion: Our results showed that such multi-disciplinary service providing centers may substantially improve the quality of life and general health of these women who rigorously need social support.

Abstract
Background and Objectives: Delivery is one of the most important services in the health systems, and increasing its effectiveness and efficiency are a health priorities. The aim of this study was to forecast the number of deliveries in order to design plans for using all facilities to provide patients with better services.
Methods: The data used in this study were the number of deliveries per month in Hakim Jorjani Hospital, Gorgan, Iran during the years 2010 to 2016. Due to the over-dispersion of the data and non-compliance with a Poisson distribution, the Poisson hidden Markov model was applied to predict the frequency of monthly deliveries. The model parameters were estimated using the maximum likelihood method and expectation maximization algorithm.
Results: The use of the Akaike criteria revealed the frequency of delivery in different months in the hospital followed a Poisson hidden Markov models with three hidden states, and the mean Poisson distribution in each component was 193.74, 236.05, and 272.61 labors, respectively.
Conclusion: The results of this study showed that government’s encouraging policies have had short-term, limited effects on increasing fertility with minimal effects on the results of the two-year forecast.

Abstract
Background and Objectives: Tuberculosis is a chronic bacterial disease and a major cause of morbidity and mortality. It is caused by a Mycobacterium tuberculosis. Awareness of the incidence and number of new cases of the disease is valuable information for revising the implemented programs and development indicators. time series and regression are commonly used models for prediction but these methods require some assumptions. The purpose of this study was to predict new TB cases using the hidden Markov model which does not require many assumption.
Methods: The data used in this study was the monthly number of new TB cases during 2006-2016 identified and recorded in Hamedan Province. Rorecasting the number of new TB cases was done using hidden Markov models using the hidden Markov package in the R software.
Results: According to the AIC and BIC criterion, two states had the best fit to the data, i.e. the data of this study were a mixture of two Poisson distributions with average number of event 5.96 and 10.2 respectively. The results also predicted the number of new cases over the next 24 months based on the hidden Markov model would be between 8 and 9 new cases in each month.
Conclusion: The hidden Markov model is the best model for prediction using the Markov chain. This model, in addition to detection of an appropriate model for the available data, can determine the transition probability matrix, which can help physicians predict the future state of the disease and take preventive measures befor reaching advanced stages.

Abstract
Background and Objectives: The aim of this study was to determine the predictability of the PLS-SEM model for injuries resulting in hospitalization in motorcyclists using a mediator variable in a case-control study.
Methods: In this case-control study, 300 cases and 156 controls were randomly selected from 150 clusters using random cluster sampling. The data were collected using the motorcycle riding behavior (MRB) questionnaire, adult attention deficit hyperactivity disorder (ADHD) questionnaire (subscales) and a checklist containing motorcycle related variables.
Results: The motorcycle riding behavior, adult ADHD, motorcycling related variables and some demographic variables were found to be the predictors of injury. There were significant positive relationships between injury and motorcycling related variables (B=0.20, P=0.001) and ADHD (B=0.33, P=0.001), between MRB and motorcycling related variables (B=0.51, P=0.001) and ADHD (B=0.52, P=0.001), and between ADHD and motorcycling related variables (B=0.39, P=0.001).
Conclusion: Considering the more accurate results of PLS-SEM, the intervention programs should especially address those who have hyperactive children, those who use the cellphone while riding, and those who ride in dark hours of the night.

Abstract
Background and Objectives: Health promotion is a crucial task for policymakers. Therefore, this study aims to identify the key factors that determine population health in Iran and illustrate the causal relationships between these factors.
Methods: The research was conducted using a mixed-method approach in three stages. First, macro social determinants of health were identified by analyzing available resources from 2000 to 2019. Screening of factors was carried out through the fuzzy Delphi method and a survey involving 15 experts. Finally, the causal relationships between the social determinants of health were depicted using a fuzzy cognitive map.
Results: Initially, 96 health determinants were identified at the national and global levels. After the screening, 8 factors that had less significance in population health were excluded. In terms of causal relationships, the economic system emerged as the most important and influential factor, with a centrality degree of 21.06 and an out-degree of 10.91. Following that, governance and policy-making, as well as national policies, were ranked with centrality degrees of 20.25 and 20.19, respectively.
Conclusion: Irrespective of the causal relationships, the health system holds the utmost importance in population health. However, when considering the causal relationships, the economic system takes precedence as the most critical factor, while the health system does not rank among the top three factors. Therefore, the analysis of fuzzy cognitive maps assists policymakers in understanding priorities and the interconnectedness between sectors in developing and implementing health-oriented policies across all sectors, enabling the adoption of the most effective policies.

Abstract
Background and Objectives: Masks play a crucial role in preventing and controlling viral epidemics transmitted predominantly through the air. This study aimed to develop and validate a tool to measure people’s attitudes and behaviors related to mask usage during highly contagious viral epidemics.
Methods: In this psychometric study, the initial questionnaire was developed and face validity and content validity were assessed by 17 experts and three lay experts. Reliability was evaluated through internal consistency using Cronbach’s alpha and test-retest reliability using the Intraclass Correlation Coefficient (ICC). Construct validity was measured using exploratory factor analysis (EFA) with the principal component extraction method and Varimax rotation.
Results: Based on a review of previous studies, an initial 27-item questionnaire was crafted. During the face validity stage, two items were excluded. Through calculating the Content Validity Ratio (CVR) and the Content Validity Index (CVI), three and one items respectively removed. The average scale level content validity index (S-CVI/Ave) was 0.95. Cronbach's alpha coefficient was found to be 0.76 for attitude and 0.66 for practice sections; the ICC was equal to 0.873. EFA revealed two factors explaining 63.98% of the total variance.
Conclusion: This questionnaire demonstrated sound reliability and validity in Persian, providing an effective means to assess attitude and behavior related to mask usage during highly contagious viral epidemics. It stands as a valuable tool for use in Iran and other countries.
