- چکیده انگلیسی: Background Domestic violence against women is regarded as an important health problem among women and a serious concern in issues related to human rights. To date, a few screening tools for domestic violence exist for Iranian married women, but they assess only some of the domestic violence components. Objectives The present study aimed to design and determine the validity and reliability of a screening instrument for domestic violence in a sample of Iranian women. Materials and Methods The present study was a cross-sectional psychometric evaluation conducted on 350 married women in Ilam, Iran, in 2014. The samples were selected through multistage sampling and the main method was cluster sampling. A 20-item, self-administered questionnaire was validated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). An Eigen value > 1 and a loading factor > 0.3 for each component were considered as indices for extracting domestic violence components. Reliability was calculated by test-retest and Cronbach’s alpha. Also, the content validity index (CVI) and content validity ratio (CVR) were used to measure content validity. The data were analyzed using SPSS-13 and LISREL 8.8 software programs. Results The self-administered instrument was completed by 334 women. The CFA and EFA methods confirmed embedding items and the three-factor structure of the instrument including psychological, physical, and sexual violence, which explained 66% of the total variance of the domestic violence. The ICC and Cronbach’s alpha coefficients were > 0.7 for the components of the questionnaire. The test-retest also revealed strong correlations for each of the domestic violence components (r > 0.6). Conclusions The used instrument for measuring domestic violence had desirable validity and reliability and can be used as a suitable instrument in health and social researches in the local population.

- چکیده:
- چکیده انگلیسی: Introduction: Acute appendicitis is the major cause of abdominal pain which indicates urgent surgery. Commonly, it is diagnosed through clinical signs and symptoms and blood test. This study aimed to assess the accuracy of acute appendicitis diagnosis through signs and symptoms, Alvarado score system, and ultrasonography method.
Methods: This was a cross-sectional study. Medical profiles of 696 patients with abdominal pain suspected of acute appendicitis referred to Shahid Faghihi hospital were reviewed from June to October 2016. A checklist was used for data collection. The gold standard for diagnosis of acute appendicitis was patient’s pathology report. For signs and symptoms, Alvarado score system and ultrasonography method sensitivity, specificity, positive and negative predictive value, and the Youden’s index were calculated based on true positive and true negative values.
Results: Among 696 patients suspected of acute appendicitis, 371 (53.3%) were men and 325 (46.7%) women. The mean age for women and men was 30.14+11.49 and 30.53+11.61 years, respectively. Sensitivity and specificity for ultrasonography and Alvarado score system were 68.1% and 78.9%, 76.1%, and 59.9%, respectively. The areas under roc curve and the Youden’s index for ultrasonography and Alvarado score system were 0.73, 0.47, and 0.71, 0.55, respectively.
Conclusion: The results showed that ultrasonography and Alvarado score system were effective pre-surgical diagnostic tests for patients suspected of acute appendicitis.- انتشار مقاله: 17-04-1397

- چکیده:
- چکیده انگلیسی: Background: Drivers of heavy motor vehicles are occupationally exposed to intense whole body vibration (WBV) for several hours per day over their working lifetime. Therefore, they are at risk of WBV-induced occupational disorders. This study aimed to investigate health effects of long-term exposure to whole body vibration among a group of heavy vehicle drivers in Fars province, southwestern Iran. Methods: Data on vibration-induced health effects were gathered through a checklist specifically devised for this purpose, interview and medical records of 155 male heavy vehicle drivers as well as 70 referent subjects. Signs and symptoms were classified into 6 categories of neuropsychological, gastrointestinal, ocular, auditory and metabolic and cardiovascular disorders. Results: Symptoms such as neuropsychological, musculoskeletal, metabolic, visual and hearing disorders were significantly more prevalent among drivers than in referent individuals. Additionally, logistic regression analysis revealed that there were statistically significant associations between exposure to WBV and several outcomes. Conclusion: Findings of the study indicate that longterm occupational exposure to WBV is a risk factor for neuropsychological, musculoskeletal, metabolic, visual and hearing disorders.

- کلمات کلیدی: Breast cancer,Case-control,gene-environment interaction
- چکیده:
- چکیده انگلیسی: Background: The traditional methods of studying the gene-environment interactions need a control group. However, the selection of an appropriate control group has been associated with problems. Therefore, new methods, such as case-only design, have been created to study such interactions. The objective of this study was to compare the case-only and case-control designs using data from patients with breast cancer.
Methods: The interaction of genetic and environmental factor as well as the ratio of control to population odds ratio was calculated for case-only (300 patients with breast cancer) and case-control (300 cases of breast cancer and 300 matched controls) designs.
Results: The confidence intervals and -2log likelihood in all variables in case-only design was smaller than those in the matched case-control design. In case-only design, the standard errors of some variables such as age at menarche, the first delivery at the age of 35 yrs and more or no delivery, the history of having live birth, use of oral contraception pills, breastfeeding history were less than those in the matched case-control design.
Conclusion: The findings indicate that the case-only design is an efficient method to investigate the interaction of genetic and environmental factors.- انتشار مقاله: 11-09-1392

- چکیده:
- چکیده انگلیسی: Background: Adolescents pay more attention to their appearance and body. Irregular nutritional patterns, eating certain types of food, and consuming more protein-containing food are more common in this age group. Considering the importance of this issue and lack of adequate studies in Iran, especially in Fars province, we aimed to assess the relationship between weight-controlling attitudes and eating disorders with dietary intake in female adolescents.
Methods: This cross-sectional study was done on 600 female students aged 14-17 years from the four educational districts of Shiraz, southern Iran, during 2011-2012 using the stratified random sampling method. Data were collected using three questionnaires as follows: demographic data questionnaire, Eating Attitudes Test (EAT-26) to assess eating attitude disorders in students, and the Food Frequency Questionnaire (FFQ). Data were analyzed using SPSS software, version 13 and the NUT 4 software.
Results: Six (1%) EAT-26 questionnaire were omitted from analysis for being incomplete. Also, 556, 446, and 491 questionnaires were evaluated in meat, bread, and fat groups, respectively; and the rest were omitted because of not being complete. The mean±SD age of the students was 15.8±0.9 years. According to the EAT-26, we found that 80.1% of the students were at risk of eating attitude disorders (CI=95%, 76.9-83.3). By comparing the results of the FFQ and the EAT-26 and weight controlling behaviors, we found that consumption of meat and fat was significantly higher in students with eating attitude disorder (P=0.027 and P=0.003 respectively). Bread intake was significantly higher in the groups with no disorder (P=0.08). (This P value is not significant.) Moreover, the mean consumption of sandwiches was higher in students with eating attitude disorders (P=0.002).
Conclusion: Considering the high prevalence of eating attitude disorders in our study, assessing the underlying reasons and implementing preventive programs is of utmost importance.- انتشار مقاله: 27-06-1395

- چکیده انگلیسی: Background
Mental health problems are common among adolescents. Proper screening and rehabilitation could improve adolescents’ function at the present time and in the future. This study aimed to assess the prevalence of psychiatric disorders and the associated familial factors among high school students.
Materials and Methods
The present cross-sectional study was conducted on 630 high school students (315 boys and 315 girls) aged 13-17 years in Jahrom, Iran. The participants were selected using random cluster sampling. The data were collected using the self-report version of strength and difficulties questionnaire (SDQ), and were analyzed using the SPSS statistical software, version 16.0.
Results: The results showed that 22.38% of the students had total difficulty (14.9% of boys, and 29.8% of girls). The highest prevalence was related to peer relationship problems (23%) followed by conduct problems (18.1%), hyperactivity (11.1%), pro-social behaviors (6.3%), and emotional problems (5.7%). The results of multivariate logistic regression analysis revealed that female gender (odds ratio [OR]: 2.52, 95% confidence interval [CI]: 1.68-3.66) increased the odds; while grade 9 (OR=0.52, 95% CI: 0.32-0.83), and number of siblings (OR: 0.88, 95% CI: 0.78-0.99) decreased the odds of mental health problems (p<0.05).
Conclusion
According to the results, the prevalence of behavioral disorders was relatively high among the students. The number of sibling, being girl and being in nine grade significantly contributed to the prevalence of behavioral disorders. In order to reduce these disorders, familial intervention and educational programs are recommended to be designed and implemented to prevent and treat behavioral disorders among students.- انتشار مقاله: 20-10-1396
