Reliability and Minimal Detectable Change Values for Performance-Based Measures of Physical Functioning in the Canadian Longitudinal Study on Aging.

Background: The aim of this study was to determine the relative and absolute reliabilities of 5 key performance-based measures of physical function in the Canadian Longitudinal Study on Aging (CLSA).

Methods: An age-stratified subsample of 147 participants from the CLSA who were undergoing their 3-year data collection visit participated in 2 repeat visits (within 1 week). Participants underwent tests of grip strength, 4-m gait speed, Timed Up and Go (TUG), chair rise, and single-leg stance (left, right, mean, maximum).

Bull bars and vulnerable road users.

Objectives: Pedestrian injuries are a leading cause of the global death and injury burden, accounting for 65 percent of the 1.2 million annual road deaths. The purpose of this brief literature review is to examine whether bull bars, a rigid aftermarket accessory fitted to the front end of passenger vehicles, increase the risk of severe and fatal injuries to vulnerable road users in the event of a collision.

Does obesity increase the risk of injury or mortality in motor vehicle crashes? A systematic review and meta-analysis.

The objective of this review was to assess the risk of obesity in injuries and fatalities resulting from motor vehicle crash (MVC), as compared with individuals with a normal-range body mass index. A systematic review of the literature was conducted yielding 824 potential studies. Nine of these studies met our inclusion criteria.

Injury prevention in child death review: child pedestrian fatalities.

Objective: This article describes the epidemiology of child pedestrian fatalities in British Columbia using data generated by the province's Child Death Review Unit, to demonstrate the unique capacity of child death review to provide an ecological understanding of child mortality and catalyse evidence based, multi-level prevention strategies.

Methods: All child pedestrian fatalities in British Columbia from 1 January 1 2003 to 31 December 2008 were reviewed. Data on demographics, circumstance of injury, and risk factors related to the child, driver, vehicle, and physical environment were extracted.

Sociodemographic factors associated with aggressive driving behaviors of 3-wheeler taxi drivers in Sri Lanka.

Little is known about the nature and scope of aggressive driving in developing countries. The objective of this study is to specifically examine the sociodemographic factors associated with aggressive driving behavior among 3-wheeler taxi drivers in Sri Lanka. Convenience samples of 3-wheeler taxi drivers from Rathnapura, Ahaliyagoda, Sri Lanka were surveyed from June to August 2006.

Youth injuries in British Columbia: type, settings, treatment and costs, 2003-2007.

In this study, the types and costs of unintentional injuries among adolescents transitioning to adulthood are examined to provide age-appropriate prevention strategies. The data were collected in 2003, 2005 and 2007, in which a total of 273 (41%), 228 (39%) and 176 (33%) youths, respectively, reported to be having at least one serious injury. The leading types of injuries were sprains/strains, broken bones and bruises.

Are 1994 alcohol production and the sales deregulation policy in Japan associated with increased road traffic fatalities among adult and teenage males and females in Japan?

Introduction: International studies have shown a significant association between alcohol availability and traffic crashes that involve alcohol-impaired drivers. A key limitation to previous alcohol availability and motor vehicle crash (MVC) evaluation research is the assumption of population homogeneity in responding to the policies. The present analysis focuses on the evaluation of the impact of alcohol availability on different segments of the Japanese population by comparing MVC fatality rates from before and after implementation of the alcohol deregulation policy in 1994.
