RESUMO
Children on Canadian farms are at high risk for fatal injury. Ongoing surveillance of these deaths is required to affirm recurrent patterns of injury, and to determine whether historical approaches to prevention have resulted in declines in the occurrence of these traumatic events. We analyzed epidemiological patterns and trends in the occurrence of fatal pediatric farm injuries over 23 years. Records of deaths were obtained from the Canadian Agricultural Injury Reporting system. To contrast more recent data with injury patterns described historically, cases were compared between two time periods. An intentional consensus process was used to finalize key patterns and their clinical or social importance. 374 fatal farm injuries to children in Canada were identified over the 23 years of study; 253 in period 1 and 121 in period 2. While machinery and non-machinery causes of death varied between the two study periods, mean annual rates of fatal injury (approximately 4 per 100,000 children) remained similar. Notably emergent types of injury in recent years included those caused by all-terrain vehicles, skid steer loaders, and drownings. Observed declines in the numbers of fatal farm injuries are most likely attributable to analogous declines in the number of registered farms in Canada. Our findings call into question the effectiveness of pediatric farm safety initiatives that primarily focus on education. Second, while CAIR fatality data are maintained, surveillance of hospitalized injuries has been disbanded and the fatality records require updating. Only by doing so will such surveillance findings provide comprehensive information to inform prevention.

OBJECTIVE: To evaluate the implementation of an all-inclusive philosophy of trauma care in a large Canadian province. BACKGROUND: Challenges to regionalized trauma care may occur where transport distances to level I trauma centers are substantial and few level I centers exist. In 2008, we modified our predominantly regionalized model to an all-inclusive one with the hopes of increasing the role of level III trauma centers. METHODS: We conducted a population-based, before-and-after study of patient admission and transfer practices and outcomes associated with implementation of an all-inclusive provincial trauma system using multivariable Poisson and linear regression and Cox proportional hazard models. RESULTS: In total, 21,772 major trauma patients were included. Implementation of the all-inclusive model of trauma care was associated with a decline in transfers directly to level I trauma centers [risk ratio (RR) = 0.91; 95% confidence interval (CI): 0.88-0.94; P < 0.001] and an increase in transfers from level III to level I centers (RR = 1.10; 95% CI: 1.00-1.21; P = 0.04). These changes in trauma care occurred in conjunction with a 12% reduction in the hazard of mortality (hazard ratio = 0.88; 95% CI: 0.84-0.98; P = 0.003) and a decrease in mean trauma patient hospital length of stay by 1 day (95% CI: 1.02-1.11; P = 0.02) after adjustment for differences in case mix. CONCLUSIONS: In this study, introduction of an all-inclusive provincial trauma system was associated with an increased number of injured patients cared for in their local systems and improved trauma patient mortality and hospital length of stay.

BACKGROUND: Concussion education is recommended to increase concussion knowledge, beliefs, and reporting intentions. The Concussion Awareness Training Tool for Youth (CATT-Youth) is a 40-minute e-Learning module developed for high school-aged youth. AIM: The aim of the study was to evaluate changes in concussion knowledge, beliefs, and reporting intentions in high school youth from Calgary, Canada, following completion of the CATT-Youth. METHODS: This study used a modified stepped-wedge trial design. High school classes were randomly assigned to an intervention (Ix) or delayed intervention (DIx) group. Ix group participants completed a pre-CATT survey immediately followed by the CATT-Youth, then a post-CATT survey 2 to 6 weeks later. DIx group participants completed two pre-CATT surveys 2 to 6 weeks apart, with the CATT-Youth completed immediately following the second pre-CATT, then a post-CATT survey 2 to 6 weeks later. The pre-/post-CATT survey encompassed 11 subtests evaluating concussion knowledge, beliefs, and reporting intentions. Independent mixed linear regression models were conducted to examine changes in scores for each subtest. RESULTS: Participants included 454 high school students: five Ix schools (16 classes, n = 323) and two DIx schools (six classes, n = 131). The CATT-Youth significantly increased general concussion knowledge, Ix δ = 0.546/8 (95% confidence interval [CI] = [0.243, 0.849]), DIx δ = 0.728/8 (95% CI = [0.389, 1.106]), and beliefs about capabilities, Ix δ = 2.462/28 (95% CI = [1.086, 3.838]), DIx δ = 3.219/28 (95% CI = [1.594, 4.844]) for both groups. For some subtests, improvements were noted in the DIx group only. CONCLUSION: The CATT-Youth module improved concussion knowledge and beliefs about capabilities for students in both groups. Future studies should explore the utility of the CATT-Youth in changing knowledge, beliefs, and reporting intentions in high school students.
RESUMO
COVID-19 restrictions led to reduced levels of physical activity, increased screen usage, and declines in mental health in youth; however, in-depth understandings of the experiences of high school student-athletes have yet to be explored. To describe the experiences of the COVID-19 pandemic on student-athletes' physical activity, social connection, and mental health, 20 high school student-athletes living in Calgary, Alberta participated in semi-structured interviews, designed using phenomenography. Participants reported variations in physical activity, social connections, and mental health which were influenced by stay-at-home restrictions and weather. Access to resources, changes to routines, online classes, and social support all influenced engagement in physical activity. School and sports provided opportunities for in-person social connections, impacted by the onset of the pandemic. Participants reported their mental health was influenced by social connections, online classes, and physical activity. Findings from this study will inform the development of resources for high school student-athletes amidst COVID-19.

This study was conducted to determine the prevalence and reliability of risk factors collected on uninjured cyclists-pedestrians in Edmonton, Alberta, and what characteristics predict cyclist-pedestrian visibility. At randomly selected locations from July 2004 to August 2004, two independent observers recorded cyclist-pedestrian characteristics such as age, sex, clothing color, use of reflectors, flags, helmets, and a subjective impression of visibility. Data were collected on 836 individuals; most were either walking/jogging (approximately 63%) or cycling (approximately 33%). For non-cyclists, the prevalence of bright colored clothing on the trunk ranged from 12.7 to 14.7%. Few people used any kind of reflective strips. Inter-observer agreement (Kappa) ranged from 0.37 (visibility assessment) to 0.99 (sex). For cyclists, 17-19% of headgear was brightly colored, and 13-14% was white. Approximately one-fourth had a front light; half had a rear reflector. Few cyclists used a flag and just over half used spoke reflectors. Kappa ranged from 0.35 (observer assessed speed) to 0.95 (head gear and sex). A major trunk color of orange, red, yellow or white resulted in a higher visibility rating for both cyclists and pedestrians. The results indicate a low prevalence of visibility aid use among cyclists and pedestrians, but there appears to be acceptable inter-observer reliability for most data collected. Further work is required before an overall visibility rating can be used in place of component scores.

OBJECTIVE: This paper details an observational study that estimates rates for wearing seat belts in rural Alberta and compares them with rates derived from a similar study conducted in 1999. METHOD: Direct observations of drivers and front-seat passengers of 72,593 light-duty vehicles were carried out at 334 survey locations in communities with populations of fewer than 25,000, throughout northern, central and southern Alberta. In addition to seat belt use, information collected included vehicle type, gender of drivers and passengers and, at intersections controlled by a stop sign, whether or not the vehicle came to a complete stop. RESULTS: The results indicate that in 2001 in rural Alberta the estimated proportion of driver and front-seat passengers of light-duty vehicles using seat belts was 76.1%. When compared with 1999 data, this represents a 6.9% increase in seat belt wearing rates. The data was desegregated further to show differential wearing rates between drivers of different vehicle types, males and females, drivers and passengers, and between those who came to a complete stop at a stop sign and those who did not. The time of day in which data collection took place also had some influence on seat belt wearing rates. DISCUSSION: This study contributes valuable information to programs and initiatives that aim to increase the use of seat belts in rural Alberta.

Disposal of used tires has been a major problem in solid waste management. New uses will have to be found to consume recycled tire products. One such proposed use is as ground cover in playgrounds. However, concern has been expressed regarding exposure of children to hazardous chemicals and the environmental impact of such chemicals. We designed a comprehensive hazard assessment to evaluate and address potential human health and environmental concerns associated with the use of tire crumb in playgrounds. Human health concerns were addressed using conventional hazard analyses, mutagenicity assays, and aquatic toxicity tests of extracted tire crumb. Hazard to children appears to be minimal. Toxicity to all aquatic organisms (bacteria, invertebrates, fish, and green algae) was observed; however, this activity disappeared with aging of the tire crumb for three months in place in the playground. We conclude that the use of tire crumb in playgrounds results in minimal hazard to children and the receiving environment.

The growing practice of including intentional injuries (suicide and interpersonal violence) under the injury control umbrella has produced some controversy. The present study was designed to determine whether or not there might be an empirical basis for this initiative from an ecological point of view by examining the associations among unintentional and intentional injuries across 17 geographically defined health regions. The study was set in the Province of Alberta, Canada, where health services were delivered to a population of 2.96 million persons in 1999 through 17 regional health authorities. The results of a principal components analysis showed that nearly all causes of injury-hospitalization loaded on a single factor. It was not possible to produce separate factors for intentional and unintentional injuries. The strong intercorrelation among all measures suggests that there is an empirical basis for the view that intentional and unintentional injuries belong under the same conceptual umbrella, at least at the ecological level.

BACKGROUND: Children raised on farms are exposed to many hazardous types of machinery. The objective of this study was to describe the magnitude of non-fatal and fatal farm machinery injuries in Alberta children and adolescents (0-17 years) for the years 1990-1997. To date, there have been no published studies of pediatric farm injuries in Western Canada. METHODS: Data were collected through the Canadian Agricultural Injury Surveillance Program (CAISP). Death certificates and hospital charts were audited to provide enhanced information about the circumstances of injuries related to farm machinery for farm persons aged 17 years and younger. RESULTS: A total of 302 farm machinery injuries were recorded for the years 1990-1997. Of these, 14 resulted in death. All-terrain vehicles (ATVs) were the most common cause of injury (n = 76), followed by tractors (n = 72), and power take-offs (n = 15). The predominant injury mechanism was entanglement (n = 69), followed by falls from machines (n = 57), and being pinned/struck by a machine (n = 49). The median length of hospital stay for injuries was 2.0 days. Males (median = 2.0 days) had significantly longer hospital stays than females (median = 1.0 days). There were significantly more injuries reported during the summer and autumn than during the winter and spring. Those injured in the autumn were significantly older (median = 13.0 years) than children injured in the spring (median = 9.0 years). Injury rates dropped significantly during the study period from 119.9/100,000 per year in 1990 to 50.7/100,000 in 1997. CONCLUSIONS: While injury rates have dropped, the number of injuries occurring to children on Alberta farms is of concern. The large number of ATV related injuries suggests that preventative strategies need to be focused in this area. Am. J. Ind. Med. 45:177-185, 2004.
