ISSUE ADDRESSED Australia has national, state and city targets to increase levels of cycling. The possible effect of repealing mandatory bicycle helmet legislation on the frequency of cycling in Sydney is examined. METHODS A cross sectional survey by a market research company was conducted, using quota sampling, in Sydney, Australia. Participants were 600 residents aged 16 years and older. Da...

Cycling is popular among children, but results in thousands of injuries annually. In recent years, many states and localities have enacted bicycle helmet laws. We examine direct and indirect effects of these laws on injuries. Using hospital-level panel data and triple difference models, we find helmet laws are associated with reductions in bicycle-related head injuries among children. However, ...

BACKGROUND Transportation by motorcycle and bicycle has become popular in Taiwan, this study was designed to investigate the protective effect of helmet use during motorcycle and bicycle accidents by using a propensity score-matched study based on trauma registry system data. METHODS Data of adult patients hospitalized for motorcycle or bicycle accidents between January 1, 2009 and December 3...

BACKGROUND Head injuries are the leading cause of death among cyclists, 85 % of which can be prevented by wearing a bicycle helmet. This study aims to estimate the incidence of pediatric bicycle-related injuries in Olmsted County and assess differences in injuries between those wearing helmets vs. not. METHODS Olmsted County, Minnesota residents 5 to 18 years of age with a diagnostic code con...

OBJECTIVE To assess the factors, including helmet use, that contribute to head linear and angular acceleration in bicycle crash simulation tests. METHOD A series of laboratory tests was undertaken using an oblique impact rig. The impact rig included a drop assembly with a Hybrid III head and neck. The head struck a horizontally moving striker plate. Head linear and angular acceleration and st...

BACKGROUND Bicycle helmet laws generally increase helmet usage, but few studies assess whether helmet laws reduce disparities. The objective of this study is to assess changes in racial/ethnic disparities in helmet use among high school students in urban jurisdictions where laws were previously determined to increase overall helmet use. METHODS Log-binomial models were fit to four districts' ...

BACKGROUND Although bicycle helmets are effective in preventing head and brain injury, some helmeted individuals nevertheless sustain head injury. One of the possible reasons may be poor fit of the helmet on the head. This study was undertaken to examine the relationship between helmet fit and risk of injury. METHODS 1718 individuals who were helmeted riders in a crash were queried on helmet ...

Background The research literature was systematically reviewed and results were summarized from studies assessing bicycle helmet effectiveness to mitigate head, serious head, face, neck and fatal head injury in a crash or fall. Methods Four electronic databases (MEDLINE, EMBASE, COMPENDEX and SCOPUS) were searched for relevant, peer-reviewed articles in English. Included studies reported medi...
