Bicycle helmets reduce fatal and non-fatal head and face injuries. This study evaluated the effect of mandatory bicycle helmet legislation targeted at those less than 18 years old on helmet use for all ages in Alberta. ⋯ Bicycle helmet legislation was associated with a greater increase in helmet use among the target age group (<18). Though HP increased over 2-fold among adolescents to an estimated 63% in 2006, this percentage was approximately 30% lower than among children <13.

This study was designed to determine the incidence rate and risk factors of missed injuries in major trauma patients in the emergency department (ED). Hospital records of all 976 trauma patients visiting the ED and admitted to intensive care units (ICUs) of a medical center in Taiwan from 2006 to 2007 were reviewed. Missed injuries were defined as those not identified in the ED but recognized later in the ICUs. ⋯ The most commonly involved body region of missed injuries was the head/neck, followed by the chest and extremities. Results of a Cox regression analysis showed that a younger age, more-severe injury, polytrauma, and the absence of soft-tissue injuries were significantly associated with missed injuries, while younger ages, more-severe injuries, and the presence of chest and pelvic injuries were also significantly associated with clinically significant missed injuries. In conclusion, a considerable number of injuries, particularly to the head/neck, may be undetected in the ED, while young people and patients with certain injury patterns such as severity levels, polytrauma, and the presence of a chest or pelvic injury are more likely to have missed injuries and/or clinically significant missed injuries.

In the current study, research was conducted in five cities in China to examine seatbelt use and to explore Chinese drivers' attitudes toward using seatbelts. Multiple data collection methods consisted of 35 initial semi-structured interviews to create questions for an in-person survey and 500 driver observations that included administering the in-person survey. ⋯ Also examined were the relationships between seatbelt use (both objective observation and subjective self-reported use) and self-reported car crashes and traffic violations. This study provides insight into the attitudes of Chinese drivers on seatbelt use and potential interventions.

This study investigated (i) the prevalence of conversing on a cell phone while driving in New Zealand, (ii) respondents' perception of risk regarding this behaviour and (iii) attitudes towards legislation banning cell phone use while driving. In addition, the study examined the association between the prevalence of conversing on a cell phone and risk perception. Anonymous, self-reported, survey data was collected via the internet from 1057 drivers nationwide regarding the frequency of conversing on a cell phone, including hands-free and hand-held conversing, risk perception, views on legislation, and demographic information. A positive relationship was found between the frequency of conversing on a cell phone and risk perception; that is, as the frequency of conversing on a cell phone increased, the perceived risk of this behaviour decreased.

There have been many studies of the link between the level of policing in an area and the behaviour of local drivers, but those that have been conducted in the United Kingdom were either small scale or were conducted many years ago. Consequently, a practical trial was carried out in London in May 2008 to investigate the effects of increasing the level of traffic policing in a busy urban area under modern conditions. Operation Radar ran for four weeks and increased the visible presence of police on a six mile stretch of the A23 in South London. ⋯ These surveys measured vehicle speeds and drivers' use of mobile phones and seatbelts. Vehicle speeds reduced systematically during the operation along the route and in surrounding areas, and some effects remained at least two weeks after the operation had finished. The survey data do not, however, show any positive effect of enforcement on the use of mobile phones or seatbelts.
