Abstract
Background and Aim: Patients with hemophilia and thalassemia are at high risk for hepatitis C virus (HCV) infections. Unscreened blood and blood products are thought to be the most important risk factors in these two groups.
Materials and Methods: Blood samples were collected from 98 thalassemia patients and 74 hemophiliacs in Markazi province. The presence of anti-HCV antibody was tested by a third generation enzyme immunoassay. All ELISA-reactive samples were tested with the confirmatory third-generation recombinant immunoblot assay RIBA. We used a specially designed questionnaire to obtain data from patients and the software package SPSS 11.5 for statistical analysis.
Results: HCV antibody was detected in 5 thalassemia patients (5.1%) and 31 hemophiliacs (41.9%). Anti-HCV positivity in patients with thalassemia was associated with the total volume of the transfusions, splenectomy, and the duration of treatment. In hemophiliacs, seropositivity was significantly associated with the duration of transfusion treatment (P=0.01) and disease severity (P=0.00). The prevalence of HCV antibody in thalassemia subjects dropped from 8.1% to 0% after the implementation of anti-HCV screening in1996.
Conclusion: In Markazi province, the current policy of screening donors for anti-HCV and the strict safety controls on factor concentrates can effectively protect thalassemia and hemophilia patients from HCV infection.

Abstract
Background and Aim: Work-related Musculoskeletal Disorders (WMSDs) are the most prevalent occupational diseases and injuries. The aim of this investigation was WMSDs risk factors study in building construction industry by PATH (Posture, Activity, Tools and Handling) method.
Materials and Methods: This analytical-descriptive and cross-sectional study was conducted in four construction sites. A total of 3100 observations of 89 workers in 14 jobs were obtained. The percent of time determined for trunk, legs and hands postures, and manual material handling activities, used tools and handling in job tasks.
Results: Trunk, legs and hands postures, tools and objects weight differed significantly between stages (P<0.0001). Neutral trunk posture was observed frequently. Neutral legs and hands postures were observed greater than %50 and %80 of the time respectively in studied workers. Tools are used with different frequency in studied jobs. Loads with less than 5 Kg were handled repeatedly.
Conclusion: The result of this study can be used to reduce musculoskeletal disorders in construction workers. This study revealed construction workers spent more time with neutral postures. But ergonomic interventions should be accomplished in specified jobs.

Abstract
Background and Aim: The prevalence of congenital hypothyroidism (CH), one of the main causes of preventable mental handicap in neonates, is much higher in Iran than the global average.
The objective of this study was to identify risk factors for congenital hypothyroidism (CH) by using the screening program in Fars Province, Iran, during the period 2003-2006.
Methods and Materials: A case-control study was carried out, the samples being 126 cases and 401 controls. The neonates were those born between 2003 and 2006, under coverage of the National Congenital Hypothyroidism Program. The data were analyzed using the univariate and multivariate analysis tests.
Results: An increased risk for CH was detected in infants with consanguine parents, by a multivariate analysis test (odds ratio (OR) = 2.9, 95% confidence interval (CI):1.8-4.8). The test also confirmed previously reported statistically significant associations with additional birth defects OR = 2.2 (1-4.6), birth defects in first-degree relatives OR = 4.7 (1.6-4.8), female gender OR = 1.9 (1.1-3), and twin births. Although not significant, an increased risk for CH was observed among infants with gestational age<30 weeks (preterm delivery) (OR = 1.7(0.9-1.3)).
Conclusion: This study identified risk factors contributing to the etiology of CH. In particular, our results suggest a multifactorial origin of CH, in which both genetic and environmental factors play a role.

Abstract
Background and Aim: The lack of balance between job needs and workers' physical capacity may lead to work-related musculoskeletal disorders (Wises). WMSDs are one of the most important occupational health problems in developing countries. These problems are due to risk factors such as poor work postures, excessive force applied, repetitive movements, vibration, prolonged work duration, and psychological factors, leading, ultimately, to disorders ranging from mild low back pain to severe disabilities. This study aimed at determining the prevalence of WMSDs in different body regions, assessing posturing, and detecting ergonomic and individual risk factors causing musculoskeletal disorders, in Araki bakery workers in Arak, Iran.
Methods and Materials: In this cross - sectional study 233 randomly selected bakery workers in Arak were included, and the prevalence of symptoms of musculoskeletal disorders and their risk factors, with particular emphasis on work posture, was determined in them. The method used was OWAS and the NMQ Questionnaire.
Results: The highest prevalences of musculoskeletal disorders were in the knees (62.2%), low back (58.8%), legs (53.9%) and shoulders (44.6%) of the workers. Low back and shoulder injuries in Shaaters (workers in charge of baking the bread) and elbow, thigh and low back disorders in Choongeers (workers in charge of dividing and rounding the dough) were more prevalent than in other occupations. There is a positive association between type of occupation and these disorders (p<0/05). According to the OWAS's classification, the distribution of bakery workers' working postures was as follows: 58.5% in the action category 1 (natural posture), 34.7% in the action category 2 (stress posture), 4% in the action category 3 (harmful posture), and 2.5% in the action category 4 (very harmful posture). There was a significant relation between work service record and neck, elbow, shoulder, and knee disorders (p<0/05).
Conclusion: This study revealed that the working postures of 42.2% of Aaraki bakery workers were slightly to very harmful postures in addition, there was a high prevalence of WMSDS in different body regions of the workers. Ergonomic interventions are essential to improve the situation and protect better the health of the workers.

Abstract
Background and Aim: In the raw furniture preparation workshops, in which the workers usually have an undesirable postures when at work, ergonomic assessment and the work environment improvement seem essential. Developing checklists and calculating ergonomic indices would be useful in this assessment. This study was conducted with the objectives of assessing musculoskeletal disorders (MSDs) risk factors and determining types of corrective measures in raw furniture preparation workshops.
Materials and methods: After conducting task analysis, 268 workers were assessed using an ergonomic checklist developed for the purpose and ergonomic indices were calculated. The Nordic musculoskeletal disorders questionnaire was used to determine the prevalence rate of MSDs among the workers. Data were analyzed using the t-test and the test of proportions.
Results: The highest prevalence was in the lower back (38.4%) and the knees 36.2%). Statistical analysis revealed that there were significant associations between MSDs and calculated ergonomic indices (p<0.001). In addition, calculation of OR revealed that ergonomic conditions were associated with MSDs in different body parts (OR=2.90-9.49, p<0.001). On the whole, the working conditions of 32.46% of the workers studied were poor from an ergonomic point of view.
Conclusion: The checklist developed was found to be an appropriate and low-cost tool for ergonomic assessment. The most important problems in the workshops were due to inappropriate general working conditions, inappropriate organization, and unsuitable work stations.

Abstract
Background and Aim: Cardiovascular diseases are the main cause of death in the world. Several factors such as lifestyle can alter incidence of these diseases. Cardiovascular diseases originate from childhood therefore, early prevention must begin from childhood and adolescence in order to be able to modify risk factors. The aim of this study was to identify modifiable (tobacco smoke exposure, physical inactivity, hypertension, obesity, incorrect dietary habits and high blood pressure) and non-modifiable (family history) cardiovascular risk factors in Hamedani adolescents.
Materials and Methods: This was a descriptive- analytic Cross- Sectional study, including 1000 students selected by stratified cluster sampling, from 8 high schools in Hamden, Iran. The subjects’ height, weight and blood pressure were measured and their body mass index (BMI) was calculated. A questionnaire was used to obtain information on life style.
Results: On the whole, 23% of the participants had a family history of hypertension and hyperlipidemia. The data also showed that 10.7% of the participants had a BMI more than 25kg/m², 59% had no physical activity, more than 50% had a high intake of salt, and 67% were exposed to passive tobacco smoke. The average length of time spent daily on watching T.V. or playing video games was 6 hours. Proportions of the subjects consuming saturated oils, high-fat dairy products, ready-to-eat foods, and junk foods (potato chips and puffed cereals) were 50.8%, 33.1%, 48.6%, and 75.4%, respectively. The most common method of cooking was frying (used by 35.9% of the families). Finally, 3.4% of the adolescents were smokers themselves and 25% of them said that their friends smoked, while 67.7% were exposed to cigarette smoke from their smoker-relatives.
Conclusion: Most of the Hamedani adolescents are at risk of cardiovascular diseases risk factors. Primary intervention programs should be designed and implemented aiming at promoting the health and nutritional awareness and, ultimately, practice, of the general population with particular emphasis on adolescents.

Abstract
Background and Aim: Coronary artery disease (CAD) and its complications at a low age are more serious and more progressive than at higher age. Because of this difference in the natural history of the disease as a function of age, this study was conducted to compare CAD risk factors between two age groups, namely people below and above 45 years old.
Materials and Methods: Two groups of 200 hospitalized CAD patients each, one below, and one above, 45 years old were selected by simple random sampling between 2005 and 2007. Two groups were similar with regard to dates and duration of hospitalization. The following data were collected from the patients' hospital files and analyzed using SPSS/Win: age, sex and marital status area of residence a history of smoking, diabetes, and hypertension a family history of early-onset cardiovascular disease (CVD) weight and height and lipid profile. The logistic regression test was used to compare the variables between the two groups.
Results: The following variables were found to be positively associated with CAD in the under-45 year group: smoking history (OR=2.54 p=0.009), a history of early-onset CVD (OR=3.15 p=0.009), low high- density lipoprotein cholesterol (HDLc) (OR=5.53 p<0.001), and high blood cholesterol (OR=3.96 p<0.006).
Conclusion: The most important coronary heart disease risk factors at a lower age are smoking, a history of early-onset CVD, low blood HDLc, and high total blood cholesterol.

Abstract
Background and Aim: Definition of World Health Organization 1948 for Health includes social domain which two other domains of health, physical and mental, have counter effects on it. Quantity and quality of an individual relation to community in order to improve population welfare is a definition for social health. Social capital and security improvement and reduction of impoverishment and inequity is the impact of this relation and it's opposite side is increasing social problems. In this article, by reviewing social health situation of Iranian community and analysis of it's determinants, improvement strategies have been provided and role of Ministry of Health and Medical Education(MOHME) proposed.
Materials and Methods : This is a descriptive and analytic study A conceptual framework were described based on a nationally committed definition of social health and used for description and analysis. Secondary data of reviewing existing research and documents were utilized for situational analysis Focus group discussion of steering/stakeholder committee members and review of the best evidences and international experiences made analysis and proposed interventions.
Results: The evidences show that average increasing rate of social problems during recent years is 15% annually. Albeit, it is not possible to draw the increasing or decreasing trend of social health indices precisely since past 2 decades due to the lake of surveillance system. Several social problem reduction and social health improvement interventions are running by organization but, inadequate sensitivity of responsible persons, not to evaluate the current interventions, inadequate utilization and coverage of population from primary level preventive services, inappropriate selection of essential interventions, allocation of most available resources to tertiary level of prevention(after harm services), weakness of activity implementation system and intersectoral collaboration for executing interventions, disintegration of social health related financial resources and inadequate sensitivity and competencies of people in combating to social problems and risks are obstacle to effective interventions in improving social health indices. Economical, political, international and technological big changes should be added to these reasons.
Conclusion: Social health progress will not be achieved without intersecotral collaboration Improvement of existing situation is not under duties and responsibilities of MOHME, so proposed direction including vision, strategic objectives and interventions, for social health should be implemented partially by MOHME Remaining parts required advocacy to be done by other sectors. It is essential that the proposed program be approved in health policy council of MOHME for implementation of this direction and achieving to it's objectives and then be approved by health and food security high council and social council of country after that the intersectoral collaboration agreements of social health improvement should be supervised deeply.

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: The incidence of breast cancer in women is expected to rise sharply over the coming decades in Iran. The aim of this study was to determine risk factors for breast cancer in under-50-year-old women during the period 2013-2015 in Kermanshah, Iran.
Materials and Methods: This case-control study was carried out in Imam Reza Hospital and private clinics of oncologists (three clinics) in Kermanshah, Iran. The participants were 202 patients with breast cancer and 398 without breast cancer. Subjects of the experiment group were selected from among patients in the Departments of Oncology, Radiation Therapy, and Chemotherapy of the hospital, while the control group subjects were selected from among outpatients referred to specialty and subspecialty departments and private clinics of the hospital (outpatient, oncology, gynecology, ophthalmology, sonography, ENT, infertility). The two groups were matched for age. Data were collected by interviewing the subjects, the Gill standard questionnaire and the patients’ files and analyzed using the STATA software (version 12) ─ Odds Ratio (OR), 95% Confidence Interval (CI) and the Conditional logistic regression model.
Result: The following variables were found to be the most important risk factors for breast cancer among under-50-Year-old women: a family history of breast cancer in second degree relatives, an age of 18-35 years at the first childbirth, and a history of a benign breast lump.
Conclusion: It is recommended to conduct further studies on the subject with due consideration of other risk factors for breast cancer, as well as education of women about breast self-examination and importance of periodic clinical examinations.

Abstract
Background and Aim: Cardiovascular diseases (CVDs) are a major cause of death worldwide. The objective of this study was to determine the most important behavioral (inadequate nutrition, low physical activity, smoking and alcohol consumption) and non-behavioral (stress, high blood sugar, dyslipidemia, hypertension and obesity) risk factors for CVD among CVD patients hospitalized in Kermanshah Heart Hospital. This was a needs assessment study aiming at designing interventions for reducing CVD risk factors.
Materials and Methods: In this cross-sectional study 402 CAD patients (60.4% males and 39.6% females) were selected by consecutive sampling from among those hospitalized in Imam Ali Hospital for the first time. Data were collected using the Iranian version of WHO Stepwise questionnaire and the patients’ files and analyzed using the SPSS-16 software.
Results: The mean (±SD) age of the patients was 54.2 (±8.8) years. About 73% of them had a poor diet and 46.5% had low physical activity; in addition, 36% of the men had consumed alcohol in the previous year and 26.1% were smokers. Non-behavioral risk factors were quite common too. The proportions of the patients suffering from diabetes, hypertension and overweight-plus-obesity and abdominal obesity were 49.3%, 48.0%, 54.7% and 61.0%, respectively. Finally, 43.3% of the patients had high stress, 31.0% were hypertriglyceridemic and in another 21% hypercholesterolemia was seen.
Conclusion: Based on the findings it can be concluded that, as compared to other risk factors, imbalanced nutrition was more prevalent common among the patients. Another major risk factor was obesity, particularly abdominal obesity. In addition, blood glucose disorders were more common than dyslipidemia.

Abstract
Background and Aim: The aim of this study was to determine the risk factors of growth failure of one-year old children in the suburban regions of Bandar-e-Abbas City based on a population-based cohort study conducted by Bandar Abbas Health Research Station, affiliated to School of Public Health, Tehran University of Medical Sciences in the south of Iran.
Materials and Methods: In this prospective cohort study in 2021, data on the growth of 540 one-year old infants obtained in a cohort study aiming to identify contributors to mother and child health in the suburbs of Bandar-e-Abbas City, Iran were used. The outcomes included weight, height, and head circumference growth failures among one-year infants. Data analysis was performed using the STATA software version 14, the statistical tests being descriptive statistics and univariate and multiple logistic regressions.
Results: Low birth weight was found to increase the odds of one-year-old children’s weight growth failure 3.05 times (the adjusted odds ratio, OR = 3.05; 95% CI: 8.91-1.04). A low socioeconomic status reduced the odds of head circumference growth failure 59% (the adjusted OR = 0.41; 95% CI: 0.19-0.89), and a low birth weight increased the odds of head circumference growth failure 2.46 times (adjusted OR = 2.46; 95% CI: 1.01-5.97). None of the maternal and childhood factors were related to the one-year-old child height growth failure.
Conclusion: The findings of this study show that low birth weight increases the odds of normal body growth and head circumference growth failures at the age on one year, while a low socioeconomic status reduces the odds of head circumference growth failure. There are no relations between any of the maternal and childhood factors and height growth failure at the age of one year.
