Abstract
Background and Objectives: Designing and application of experimental studies in veterinary medicine have
been given paid more attention in recent years. This review aimed to evaluate the methodological quality of all
published articles in Journal of the Faculty of Veterinary Medicine, University of Tehran between 2000 and 2009.
Methods: Evaluation studies with experimental designs were identified by reviewing titles and abstracts. Two
reviewers coded reporting quality of articles.
Results: Of the 738 total published articles, 289 (39.16%) articles had experimental designs. Sample size was
reported in 93.4% of studies, only 36% of studies explained their study design clearly and randomization was
reported only in 33.6%. The ethical approval was mentioned in only two percent. Seventy six percent studies had
comparison group.
Conclusion: The quality of reporting of experimental studies in the Journal of the Faculty of Veterinary Medicine
was not generally acceptable. Therefore it is felt that authors should consider more necessary criteria for
standard publication in veterinary journals.

Background & Objectives: There is little known about the relation between metabolic
syndrome and fiber intake are available in Iran. We evaluated the relation
between total, and various types and sources of dietary fiber and the
prevalence of the metabolic syndrome.
Methods: In this cross sectional study, 2457
adults, aged 19-84 years were studied. Total dietary fiber intake and its types
and sources were assessed using a validated semi quantitative food-frequency
questionnaire. Blood pressure, Anthropometric, and biochemical measurements
were assessed. The metabolic syndrome was defined according to definition by
Iranian National Committee of Obesity.
Results: In the
multivariate-adjusted odds ratio, intakes of total (OR: 0.53 95% CI:
0.39-0.74), both soluble
(OR: 0.60 95% CI: 0.43-0.84) and insoluble dietary fiber (OR: 0.51 95% CI:
0.35-0.72), fruit fiber
(OR: 0.51 95% CI: 0.37-0.72), legume fiber (OR: 0.73 95% CI: 0.53-0.99) and
cereal fiber
(OR: 0.74 95% CI: 0.57-0.97) were inversely associated with the metabolic
syndrome. There was not significant association between using vegetable and nut
fiber and prevalence of metabolic syndrome.
Conclusion: Total
dietary fiber, both soluble and insoluble fibers, and especially fruit and
legumes fibers, reduce the metabolic syndrome among adults in Tehran.

Background
& Objectives: Cardiovascular
disease is the first cause of death and third place in disease burden in Iran.
This study estimates population attributable fraction (PAF) of cardiovascular
risk factors in Tehran population. PAF is one of the important parameters of
measuring population affect of risk factors and evaluating potential impact of
preventive strategies in community level.
Methods: In this study 5868 participants above
30 years old of Tehran lipid and glucose study (TLGS) were employed and 501 CVD
events detected during 10 years follow-up. Direct estimate of adjusted PAFs
using logistic regression which is one of less biased exist methods of PAF
calculation were applied.
Results: Highest modifiable cardiovascular
risk factor PAFs, in sequence, was smoking (14.16%), hypertension (11.73%),
diabetes (7.32%), hypercholesterolemia (6.85%) and central obesity (5.91%) for
men, and hypertension (19.25%), diabetes (18.82%), central obesity(9.88%) and
hypercholesterolemia (7.95%), for women. Also PAF of hazardous age and
premature family history of CVD, as most important nonmodifiable CVD risk
factors, were 36.09%, 16.61% and 3.95%, 7.56% for men and women respectively.
Conclusion:
According to the difference of risk factors PAFs ranking in men and women, it
is suitable that CVD preventive interventions to be prioritized by sex
separately. In this regard, besides special attention to control tobacco use in
men, hypertension and diabetes in both sexes and high cholesterol in men and
central obesity in women respectively, should be given in priority of preventive
strategies.

Abstract
Background & Objectives: Sleep quality is an important factor in student life
and affects in their learning process. Sleep problems are related to increased
health concerns, irritability, depression, fatigue, attention and concentration
difficulties, along with poor academic performance. The aim of this paper is to
conduct a survey based on a questionnaire that would characterize the quality
of sleep in students living in dormitories of Tehran University of
Medical Sciences (TUMS).
Methods: We conducted a cross-sectional study using the stratified random
sampling approach on 277 students residing in dormitories in Tehran. A
demographic questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used
for data collection.
Results: Mean (CI) of PSQI in students was 8.57 (8.10- 9.04). Using
the cut-off score of 6 for the PSQI global score, 73.3% (68.1%-78.5%) of
students were described as poor sleeper. Female students had a worse quality of
sleep compared to male. The mean duration of sleep in students was 5:15´± 105´
(hours). This was significantly higher in male students than female students.
There were no significant relationships between demographic variables such as
age, academic level, marital status and family income with and quality of
sleep.
Conclusion: This study showed that poor sleep quality is prevalent
among students living in dormitories of TUMS. Therefore it is necessary to
provide effective educational interventions for this group in order to improve
the quality of sleep.

Abstract
Background & Objectives: The aim of this study was to identify the quality of life (QOL) measures
commonly used to assess disabled people compared to healthy individuals.
Methods: A cross-sectional study was conducted in 1000 disabled and
healthy individuals aged between 15 to 75 years old during 2009 year. These
groups were selected by random sampling method multistage cluster sampling from
Crescent Comprehensive Rehabilitation Center located in Tehran. WHO's Quality
of Life (WHOQOL-100) questionnaire was used to measure quality of life.
Results: The Mean age were 35.9±12.9 and 35.1±12.7 years
amongst disabled and non disabled groups, respectively. There was a significant
difference between two groups in terms of somatic health and independence of
quality of life (P<0.001), in which the mean score in both domains were high
in healthy individuals. No significant difference was observed between two
groups in other scopes.
Conclusion: Findings of this study highlighted the lower
quality of life in disabled people in Tehran, Therefore this group should be
targeted for any relevant intervention in order to improve their care.

Abstract
Background & Objectives: The case-cohort study is one of the youngest designs in epidemiology and some methodological aspects of it are still in debate. This study aimed at comparing the estimated hazard ratio, standard error, and interaction hazard ratio between the case-cohort and cohort studies for assessing the relationship between diabetes and cardiovascular diseases.
Methods: A total of 1701 men and 2253 women aged between 40 and 75 years were considered as the main cohort. Subcohort sampling was performed using simple random sampling with a sampling fraction of 0.3%. The hazard ratio of the cohort study was calculated using Cox regression model and the 3 methods of Prentice, Self-Prentice, and Barlow were used for calculating the hazard ratio of the case-cohort study. The mentioned regression models were used to assess the interactions.
Results: The results of the two studies were similar in populations with higher incidence (cohort of men) and lower incidence (the cohort of women) when frequency percent of exposure variable was greater than 10%. When the sample size of the initial cohort was less than 1250 subjects, discrepancies were observed between the results of the two studies. In addition, the standard error of the case-cohort study was higher than the cohort study. The results of both studies were similar in assessing the considered interactions.
Conclusion: The results are similar when the initial cohort sample sizes are sufficient. Meanwhile, unlike the percentage of exposure frequency, the outcome incidence has a negligible impact on the discrepancy between the results while the effect of the relative frequency of the exposure levels on the results discrepancy is noticeable.

Abstract
Background & Objectives: Households governed by women have become an important phenomenon worldwide in the second half of the twentieth century. The study of female-headed households shows that this vulnerable social group faces many financial, physical, mental, and emotional problems and experiences stress and anxiety more than men-headed households. This study aimed to determine the quality of life in these households supported by District 9 of Tehran Municipality.
Methods: This cross- sectional study was performed on female-headed households supported by District 9 of Tehran municipality during 14 months. Data collection tools included a demographic questionnaire, the Iranian version of World Health Organization Quality of Life (WHOQOL-BREF-BREF). The data was analyzed using SPSS software version 16 and descriptive- analytic tests such as mean, standard deviation, and a multiple regression analysis. The significance level in this study was considered α < 5% .
Results : The mean age of the participants was 50.8 ± 13.8 years, and the majority of the female-headed households were unemployed (71.1 %). The findings in the four domains of quality of life showed that the domains of environment health and social relation received the lowest (9.87) and the highest (12.61) score, respectively. Using multiple regression models, it was shown that the only variables that affected the overall quality of life were age (P< 0.013) and current disease (P< 0.001).
Conclusion : Findings demonstrated that the authorities should consider planning for effective interventions to improve the quality of life in this vulnerable group of society.

Abstract
Background and Objectives: Cardiac diseases are a major cause of death in Iran. The number of deaths from cardiac diseases can be reduced through controlling air pollution. The aim of this study was to determine the relationship between increased air pollution and mortality from respiratory and cardiac diseases in Tehran.
Methods: The average daily concentrations of five pollutants, including carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and particulate matter less than 10 microns (PM10) were collected from 8 stations in Tehran, Iran. Then, their effects on the number of daily deaths due to cardiovascular and respiratory diseases were calculated using time series and Poisson GLARMA model (generalized linear autoregressive moving average). The climatic elements such as mean, maximum, and minimum temperature and daily humidity were considered as confounding factors.
Results: After adjustment for potential confounding variables of the final model of the pollutants, the mean daily ozone level (P = 0.02) and particulate matters less than 10 microns (P <0.001) had a significant correlation with the number of daily deaths.
Conclusion: According to the results of this study that addressed the relationship between air pollutants and death using new statistical methods, it is necessary to take more effective measures to control ozone and particulate matters less than 10 microns to reduce the mortality of heart and respiratory diseases in Tehran.

Abstract
Background and Objectives: Human errors are the most important factors for RTIs, which have been addressed in few quantitative studies. The objective of this study was to calculate the annual population attributable fraction (PAF) of the most important human risk factor for RTIs in the streets and highways of the Great Tehran.
Methods: In this study, the data of 124518 individuals registered in the COM114 form of the Police Information and Communication Technology (ICT- FAVA) data system of the country were employed in 2014. A regression model was applied to estimate the magnitude of the impact of traffic violations of drivers with RTIs using the adjusted relative risk ratio. To estimate the PAF, the prevalence and effect size were calculated based on the risk ratio (RR) using the baseline method or the Miettinen formula.
Results: The PAF of driving in reverse gear and failure to observe safe distance was 1.98% and 1.93%, respectively. Driving in the reverse gear and failure to observe the safe distance increased RTIs by 22% and 23%, respectively. On the highways of the Great Tehran, the largest proportion of PAF was related to driving in reverse gear (1.96%), sudden movement of the car (1.90%), speeding (1.87%). Speeding increased the risk of RTIs by 23%.
Conclusion: Monitoring traffic violations can decrease road crashes by 10% in the streets. Moreover, on highways, use of strategies to prevent traffic violations can decrease RTIs by up to 15%.

Abstract
Background and Objectives: The Problematic Internet Use Questionnaire (PIUQ) is a scale for evaluating the adverse effects of high Internet usage. It was adopted into Persian in a previous study. The factorial structure of the adopted version was different from the original English version. The purpose of this study was to determine the factorial structure of the Persian version of the Problematic Internet Use Questionnaire.
Methods: In this methodologic study, sampling was carried out in students of Iran University of Medical Sciences, University of Tehran, and Sharif University of Science and Technology. A total of 428 students completed the Problematic Internet Use Questionnaire. Exploratory factor analysis was performed using SPSS. Confirmatory factor analysis was carried out using AMOS. The reliability of the Scale was determined using Cronbach’s alpha coefficient (α=0.89).
Results: Exploratory factor analysis showed four factors including online preoccupation, adverse effects, social interactions, and excessive use. The mean ± SD of the domains was 2.12±0.81, 2.01±0.86, 2.18±0.85 and 2.39±0.97 for online preoccupation, adverse effects, social interactions, and excessive use, respectively.
Conclusion: The exploratory and confirmatory factor analysis showed that the Persian version of the Problematic Internet Use Questionnaire had a relatively similar structure with the English version. One dimension of the questionnaire was split to two new dimensions. This questionnaire can be a useful tool for measuring problematic behaviors related to the excessive use of the Internet.

Abstract
Background and Objectives: The purpose of this study was to investigate the status of HSE indices in a number of organizations affiliated with Tehran Municipality.
Methods: In this cross-sectional study, the study population included all organizations affiliated with Tehran Municipality HSE performance was assessed through an 18-item checklist. The content validity of this checklist was examined by obtaining the opinions of experts in the field. The data of this study were analyzed using the SPSS software version 22.
Results: The results of this study showed that three organizations, namely Suburbs Bus Company, Urban Planning Organization, and Terminals and Parks Organization had the best HSE performance with indexes of 63.6%, 57.485 and 52.59%, respectively. Among the 18 items of HSE performance, the HSE policy had the highest score (68.6%).
Conclusion: Based on the findings of this study, the value of the HSE index was not complete in any of the fields. The results of this study showed that although the foundation of the HSE system was implemented in many units of Tehran Municipality, it is still a long way before the desired point is reached. Therefore, it is necessary to formulate and implement appropriate action plans and to evaluate the effectiveness of control measures to improve the HSE indicators.

Abstract
Background and Objectives: The Covid-19 prevalence can threaten self-care behaviors and disease control in people with type 2 diabetes (T2D) through increasing anxiety and stress levels and limited access to medical services. This study was conducted to investigate the association of the Covid-19 pandemic with self-care behaviors in patients with T2D.
Methods: The present study was conducted on 318 adults with T2D who participated in the Tehran Lipid and Glucose Study (TLGS) between 1397 and 1399 and completed the summary of diabetes self-care activities (SDSCA) questionnaire. Data on self-care activities during the Covid-19 pandemic were collected 3-4 months after the announcement of the epidemic in the country via telephone calls. For data analysis, a multiple linear regression model and paired t-test were used.
Results: The mean total scores of self-care behaviors were 49.7±14.8 and 56.1±13.1 before and after the Covid-19 pandemic, respectively (P<0.001). After the Covid-19 pandemic, women's total self-care score increased with an increase in the diabetes duration (β= 0.31, P= 0.020) after adjusting for the aforementioned related conditions. This score showed a significant decrease in women with a high school education compared to those with higher education (β= -6.57, P= 0.024). Moreover, the diet and foot care subscales in both sexes and the blood glucose testing score in women were significantly higher after versus before the pandemic.
Conclusion: Following the Covid-19 pandemic, self-care behaviors, especially those related to diet, foot care, and blood glucose testing, improved in the short term

Abstract
Background and Objectives: Using a random sample of women aged 15 to 50 years in Tehran, this study sought to estimate the lifetime prevalence of abortion (intentional and unintentional) and to identify its associated factors.
Materials and Methods: The control data of a population-based case-control study conducted in 2014 in Tehran was used in the present study. Data from 544 randomly selected women aged 15-50 living in municipality areas of Tehran were included in this study. A multiple logistic regression model was used to investigate factors associated with abortion and to estimate the adjusted odds ratios (ORs) and 95% confidence intervals.
Results: Overall, 102 women (18.8%, 95% CI (22.4% -15.8%)) reported a lifetime history of abortion. In the logistics regression model, being single (OR =3.46, 95% CI: 1.42-8.47) older age (OR = 1.07, 95% CI: 1.04-1.11) increased the odds of a positive lifetime history of abortion. However, having a child (OR = 0.27, 95% CI: 0.11-0.65)), more education years (OR = 0.89, 95% CI: 0.82-0.96)) and higher religious beliefs (OR = 0.65, 95% CI: (0.45-0.93)) decreased the odds of a positive lifetime history of abortion..
Conclusion: High reported lifetime prevalence of abortion in the present study and its subsequent risks to maternal health highlight the need for educational interventional programs taking into account the level of education and knowledge of mothers along with their religious.

Abstract
Background and Objectives: Road accidents are a major public health problem and one of the leading causes of death in the world. Some survivors of traffic accidents experience acute stress disorder and post-traumatic stress disorder during weeks to months following the accident. These disorders can have disastrous effects on victims and their inability to return to normal living conditions.
Materials and Methods: This was a cross-sectional descriptive study. The Post-Traumatic Stress Disorder checklist (PCL5) was used to assess acute stress disorder and post-traumatic stress disorder. The sample size was 384 people and the data were collected one week and two months after the trauma in the orthopedic, emergency and inpatient wards of Taleghani, Shohadaye Tajrish and Haftom Tir hospitals. This study was conducted between October and January 2016.
Results: This study was conducted on 350 participants. About 49% of the participants (n = 172) met the diagnostic criteria for acute stress disorder and 40.6% (n = 142) met the diagnostic criteria for post-traumatic stress disorder. There was a relationship between demographic variables of age and death of a close family or friend and the severity of post-traumatic stress disorder.
Conclusion: According to the results, about half of the participants had acute stress disorder and met the diagnostic criteria of post-traumatic stress disorder. This result highlights the high prevalence of this disorder in traffic accident victims and the importance of its follow-up and control.

Abstract
Background and Objectives: Considering the growing trend of aging in Iran, it is necessary to study the factors affecting the health of elderly people. The main purpose of this study was to investigate demographic, social, and economic determinants of self-assessed health of elderly people in Tehran using generalized structural equation model (GSEM).
Methods: The data of the present study was obtained from a cross-sectional study in which 598 elderly people aged 60 years and over were selected from 22 districts of Tehran in 20151394 using stratified multi-stage sampling method and a researcher-made questionnaire was completed for them. The reliability of the questionnaire was also confirmed using and time consistency. To study the determinants of self-assessed health of elderly people, WLSMV and ULSMV estimators of GSEM were compared in Mplus (7.3).
Results: Based on the goodness-of-fit indices, the ULSMV estimator was selected to evaluate factors affecting the self-assessed health of elderly people (RMSEA=0.02, CFI=0.951 and TLI=0.962). The self-assessed health ranks of married and employed elderly people were higher than single (P-value=0.022) and unemployed (P-value=0.048) ones, respectively. An increase in spirituality (P-value=0.016), physical and mental health (P-value=0.001), and health-oriented behavior (P-value=0.016) increased the standard score of self-assessed health of elderly people. Physical and mental health played a complete mediating role in relationships of gender (P-value=0.014), marital status (P-value=0.040), education level (P-value=0.039), self-reported socio-economic status (good/ P-value=0.013 and middle/P-value=0.017) and number of diseases (P-value=0.001) with self-assessed health of elderly people.
Conclusion: According to the results, for policy-making in the field of geritrics, special attention should be paid to structural variables like gender, marital status, education level, and self-reported socio-economic status in addition to physical and mental health.

Abstract
Background and Objectives: Human resources are the center of sustainable development in advanced management. Health, Safety and Environment (HSE) is a system that consistently and by means of human resources, facilities and equipment and tries to create a healthy, pleasant, fresh environment away from accident, damage and waste. This study was conducted to assess the health performance, Safety and Environmental Indicators (HSE) in the field of human resources development of Tehran Municipality.
Methods: This study was conducted as a descriptive cross-sectional and, the study base was all 22 districts of Tehran municipality. After designing and validating of HSE performance evaluation protocol, HSE status was evaluated in 22 districts of Tehran. The aforementioned protocol contained seven sections: leadership and commitment, policy and strategic goals, organization and documentation, risk management, planning, implementation and monitoring, audit and review). Its validity and reliability were determined by obtaining corrective opinions from specialists and experts inside and outside the municipal organization.
Results: In most areas of Tehran municipality, the inter-organizational communication index was the highest score. The highest score (68%) is related to this index. The mean overall score for performance evaluation was 46.6.
Conclusion: The HSE situation was undesirable (less than 70%) in more than half of Tehran's municipalities. Regions 4 and 7 were in desirable status (above 70%). Thus, for current situation improvement, we should use long-term strategy planning in the field of HSE.

Abstract
Background and Objectives: COVID-19 pandemic caused a lot of severe problems in the world. This study investigated the epidemiology of the disease in Tehran in the first quarter of the epidemic's beginning.
Methods: The available information recorded for patients from 20 February 2020 to 20 May 2020 in Tehran was used. To prepare disease-related distribution maps, the addresses of patients' residences in Google Earth were called to ARC-GIS version 10-4. The methods used in GIS include IDW, Hotspot and also software development.
Results: Overall, 3699 individuals whose PCR results were positive in Tehran were included in the study. Out of the total number of them, 550 people died and the fatality rate of the disease in hospitalized patients was 14.9%. One thousand five hundred thirty patients (41.4%) have recovered, and the remaining 1619 patients were under treatment until data collection. Of the total, 1479 confirmed cases were women (40%). The average age was 57.4 years (SD=16.5). The density of cases in areas 4, 8 and 13, and the existence of some cluster diseases in neighborhoods such as Tehran Pars, Ayat and Pirouzi streets are noteworthy points.
Conclusion: The trend of the COVID-19 epidemic is dire and requires long-term measures. Nevertheless, to control this disease, the health system, the policy of isolating patients and suspicious people, wear masks especially in densely populated areas, are the most important controlling factors.
