Relationship between using cell phone and the risk of accident with motor vehicles: An analytical cross-sectional study / 中华创伤杂志(英文版)

PURPOSE@#Traffic accidents are one of the major health problems in the world, being the first cause of burden of illness and the second leading cause of death in Iran. The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths. This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016.@*METHODS@#This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals. The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist. Census was obtained from the study subjects. For data analysis, independent t-test, one-way ANOVA, Chi-square and logistic regression were used with the Stata software version 11.0.@*RESULTS@#In this study, 223 male subjects with the mean age of (32.54 ± 12.95) years, 39.8% single and 60.2% married, entered for investigation. Most accidents (38.8%) occurred between 12:00 to 17:59. While driving, 47.1% of the study subjects were using cell phones, 89.1% had manual use of mobile phones, 21.9% had a habit of sending short message service (SMS) and 23.4% had sent SMS within 10 min before the accident. The one way analysis of variance showed that the mean age of individuals with marital status, driving experience, education and accident with motorcycle were significantly different (p < 0.05). Also, the multivariate logistic regression test indicated a significant relationship of smoking, ethnicity, insurance and SMS typing while driving with motorcycle accident (p < 0.05).@*CONCLUSION@#In this study, SMS and smoking while driving had the highest risk among the variables studied in the motorcycle accidents. Therefore, effective education attempting to enhance people's awareness about the consequences of using cell phone and smoking during driving to reduce traffic accidents seems necessary.

Noise pollution in zahedan and residents' knowledge about noise pollution

Noise is considered one of the most pervasive and harmful agents in crowded cities. The aim of this study was to determine the exposure rate to noise pollution of residents on the main streets of Zahedan city in southeastern Iran and the knowledge and attitudes of these residents concerning noise. Noise was measured for three consecutive weeks in the October-November areas of the city in 31 test locations, using a CEL-440 Classic sound level meter and analyzer during the noisiest hours of the day [07:00 to 22:00]. Using a validated questionnaire, data were collected from 400 subjects to estimate their knowledges and attitudes about noise pollution. The average noise level in the main city streets during the day was 75 +/- 2.96 dB. The mean age of participants was 31.9 +/- 11 years. Approximately 82.3% of the subjects tested reported that street noise pollution was too high, and 48% suggested that the best way to decrease city noise pollution was to enhance people's knowledge of the problem. Furthermore, 65.8% of the subjects stated that street noise is a cause of stress. There was a significant association between noise levels and subjects' sleepiness [P < 0.05]. In addition, noise pollution in Zahedan city streets was found to be higher than standard levels. It was concluded that appropriate traffic management and a health promotion program are essential for increasing the residents' understanding about how to improve the current noise pollution situation
