However,most adolescents do not meet the current physical activity(PA) recommendations in Turkey. The role of the social environment and social factors on PAP is being increasingly recognized. Although social capital(SC) indicators have been examined in high-income countries, there are few studies on developing countries. The aim of this study was to examine the relationship between SC indicators and PAP among Turkish adolescents.Methods: A survey was conducted among 19 high schools in 4 different cities in Turkey in 2016. A total of 506 female and 729 male high school students participated in this study. The dependent variable was overall PAP, which was measured using the short form of the International Physical Activity Questionnaire. The independent variables included self-perceived family, neighborhood, and school SC. Self-rated health and obesity status, measured by body mass index, were other study covariates in multiple binary logistic regression models. Chi-square tests were used to assess the differences between genders.Results: PAP levels were significantly different between males and females. A higher percentage of males reported PAP(77.4%) compared to females(51.0%). Among males, teacher–student interpersonal trust and informal social control were inversely associated with PAP, while high students interpersonal trust was positively associated with increased odds of PAP. For females, students interpersonal trust was inversely associated with PAP.Conclusion: Various SC indicators are associated with PAP for males and females. These associations are different from findings of studies conducted in developed countries. Therefore, health-promotion interventions and policies should consider gender and different social agents on the social and cultural background to improve PAP among Turkish adolescents.展开更多

METHODS Clinical feature and colonoscopic findings of 156 MC patients were retrospectively analyzed. Final diagnosis of MC case was made after colonoscopic and pathological examination, and data of the case history was recorded. RESULTS The overall detection rate of MC was 1.12%, with 0.46% in males, 0.66% in females. An 82.69% of the patients suffered various constipations and had a history of taking cathartics. The clinical manifestation of total-colon melanosis occurred in 83.97% of the patients. There was no significant difference between the rate of concomitant polypus (27.56%) in the MC patients and the detection rate of polypus in the patients who underwent a synchronous colonoscopy (χ^2 = 1.205, P = 0.298). Also there was no significant difference between the detection rate of carcinoma of the large intestine (8.97%) in MC patients and the detection rate of the same disease in the patients who underwent synchronous colonoscopy (χ^2 = 0.268, P = 0.604). A logistic regression analysis has shown that the older the age of MC patients is, the more opportunities of MC and the concomitant polypus would occur. CONCLUSION MC may be related to constipations and a long-term administration of cathartics, among which total-colon melanosis ranks first in the cases. There is an earlier age of onset in the females, with a higher detection rate. The older the age of the patients is, the higher the detection rate of MC is, and the more possibility the onset of the concomitant polypus.展开更多

Methods: This crosssectional study was conducted in Fats Province of Iran during a 29month period from March 2009 to July 2011. The data were from the Fats Forensic Medi cine Registry, In 4 923 recorded road traffic accident fatalities, 971 deaths were due to pedestrian accidents. The demographic and accidentrelated information were analyzed by SPSS ver sion 11.5. P value less than 0.05 was considered significant. Results: The mean age of decedents was (47.2±26.2) years, ranging from 6 months to 103 years old. Males ac counted for 69.8% of all deaths. Fatal accidents were mostcommon in September; 56.1% of the fatal injuries occurred on intracity roads and 33.1% on extracity roads. Fatal head injuries were present in 60.54% of cases. Evaluation of the injury site and the cause of death found that they were significantly associated with age, interval between injury and death. Besides, the type of roads played an important role in mortality. Conclusion: Although the clinical management of trauma patients has been improved in our country in the recent decade, decreasing the burden of injuries needs co ordination among trauma system organizations.展开更多
