Abstract
Unlike other developed countries that hold national burn registries to monitor burn injury and care, Canada relies on single-centre secondary datasets and administrative databases as surveillance mechanisms. The objective of this study was to determine the knowledge gap faced in Canada for not having a dedicated burn registry. A comprehensive scoping review was conducted to identify the burn literature that has arisen from secondary datasets in Canada. Literature of all study designs was included with the exception of case reports and cases series. Once data extraction was concluded, a thematic framework was constructed based on the information that arose from nations that hold national burn registries. Eighty-eight studies were included. Twelve studies arose from national datasets, and 18 from provincial databases, most of which were from Ontario and British Columbia. Only seven studies were conducted using a combination of Canadian units' single-centre datasets. The majority of included studies (58%) resulted from non-collaborative use of single-centre secondary datasets. Research efforts were predominantly conducted by burn units in Ontario, British Columbia, Manitoba and Alberta. A significant number of the included studies were outdated and several provinces/territories had no published burn data whatsoever. Efforts should be made towards the development of systems to surveil burn injury and care in Canada. This study supports the development of a nation-wide burn registry to bridge this knowledge gap.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14328.

Abstract
Running can improve physical health and psychological wellbeing. However, the characteristics of conducive running environments are relatively unknown. This study determines neighborhood factors that attract running and explores how age and gender mediate built environment preferences. Spatial patterns of runners in Metro Vancouver were identified using crowdsourced fitness data from Strava, a popular application for tracking physical activities. The influence of socio-economic status (SES), green and/or blue space, and urbanicity on route popularity was assessed using a Generalized Linear Model (GLM). The influence of these neighborhood variables was also calculated for runners by age and gender. The results show high neighborhood SES, the presence of green and/or blue space, and high population density are associated with increased running activities in all age and gender groups. This study contributes a novel approach to understanding conducive running environments by demonstrating the utility of crowdsourced data in combination with data about urban environments. The patterns of this large group of runners can be used to inform planning for cities that promote running, as well as seek to encourage equal participation among different ages and genders.

[PMID: 34916089 DOI: 10.1016/j.burns.2021.08.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 07/28/2021] [Accepted: 08/02/2021] [Indexed: 02/05/2023]
Abstract
BACKGROUND Many studies demonstrate that being burned has both physical and psychological sequelae that affect quality of life. Further, these effects may be more prevalent in some regions and populations. We sought to access the unbalanced distributions and temporal trends concerning the health burden of thermal burns. METHODS Data were collected from the Global Burden of Disease Study 2017, and the disability-adjusted life year (DALY)1 was used as a measure of health burden. Linear regression was used to evaluate the relationship between the age-standardized DALY rate and socio-demographic index.2 Joinpoint regression analysis and comparison line charts were all applied to assess the temporal trends of burns. RESULTS The age-standardized DALY rate of global thermal burns decreased by 43.7%, from 197 (95% CI: 152-228) per 100,000 in 1990 to 111 (95% CI: 93-129) per 100,000 in 2017. The burden was borne mainly by children 1-4 years of age and people over 80 years. Socio-demographic index was negatively correlated with the age-standardized DALY rate. In low-middle and low socio-demographic index regions, the decreasing trends were slower than other regions with an average annual percentage change of -2.1% (95% CI: -2.2 to -2.0) and -2.1% (95% CI: -2.1 to -2.0), respectively. Among six geographical regions, Africa presented the highest age-standardized DALY rates of 352 (95% CI: 275-410) per 100,000 in 1990 and 208 (95% CI: 175-236) per 100,000 in 2017, and also the slowest average decreasing trend, with an average annual percentage change of -1.9% (95% CI: -2 to -1.8). CONCLUSIONS The global burden of thermal burns shows a downward trend from 1990 to 2017, and regions with lower socio-demographic index and Africa show greater burdens and smaller downward trends.

Abstract
INTRODUCTION In the "Children's Hospital Zagreb Referral Centre for Paediatric Trauma of the Ministry of Health Republic of Croatia (MHC)" we observed a significant decline in the number of both hospitalised and ambulatory treated paediatric patients with burn injuries in the period from 2011 to 2018. Our hypothesis is that this decline could be either due to the decline of the paediatric population of Croatia or due to the economic growth and the improvement in the standard of living that Croatians have enjoyed in the past decade. MATERIALS AND METHODS In this observational study, we analysed data on the numbers of patients treated due to burn injuries from January 2011 to December 2018 in the Children's Hospital Zagreb Hospital. Indicators of standard of living and population size estimates were obtained from Eurostat and the Croatian Bureau of Statistics. Associations between the proportion of people with poor standard of living and the number of treated patients were analysed with logistic regression models. RESULTS Percentage of the population with low housing standards, percentage of Croatians with low level of education, percentage of children that live in jobless households, and percentage of children at risk of poverty and social exclusion were predictors of the rate of hospital admissions, ambulatory treated patients and total number of treatments. The slight decrease in the rate of treated patients was interrupted with notable decline in 2014 followed by the slight increase in 2015. Over following years, the rate did not change remarkably. CONCLUSION Apart from the decline of the paediatric population of Croatia, it is reasonable to assume that the improvement in the standard of housing, level of education and employment rate as well as the reduction in the risk of poverty and social exclusion in children had a notable contribution to the decline in the rate of paediatric burns in the observed period.

Abstract
Globally, First Nations children sustain burns at a higher rate than other children. Little is understood about how health inequities contribute, especially from an Indigenous viewpoint. We analyzed data from the Burns Registry of Australian and New Zealand (BRANZ) for acute burns in children (<16 years) admitted to hospital between October 2009 and July 2018. Descriptive statistics examined equity variables in patient and injury characteristics. Poisson regression was used to describe factors associated with bacterial infection. Indigenous research methods were used throughout. Aboriginal and Torres Strait Islander children represented 10.4% of the study population. Health inequities were present for Aboriginal and Torres Strait Islander children with longer hospital length of stay (9.5 vs 4.6 days), rural residency (61.3% vs 13.9%), lower socioeconomic status (72.2% vs 34.9%), and more flame burns (19.5% vs 10.6%) compared to other Australian children. Streptococcus sp. infection risk was four times greater in Aboriginal and Torres Strait Islander children compared to other Australian children. Flame burns and high percentage total body surface area burns were a risk for Staphylococcus sp. and Streptococcus sp. infection in all children. The epidemiological profile for burn injuries managed in Australian burns centers differs between Aboriginal and Torres Strait Islander children and other children, indicating persistent health inequities. These differences should be considered in the development of injury prevention strategies and the clinical management of burn injuries for Aboriginal and Torres Strait Islander children and their families.

Abstract
The United States is facing a growing homelessness crisis. We characterize the demographics and outcomes of homeless patients who sustain burn injury and compare them to a cohort of domiciled patients. A retrospective cohort study was performed at the Los Angeles County + University of Southern California Regional Burn Center for consecutive acute burn admissions in adults from June 1, 2015, to December 31, 2018. Patients were categorized as either domiciled or homeless at the time of their injury. Prevalence rates were estimated using data from the regional homeless count. From 881 admissions, 751 (85%) had stable housing and 130 (15%) were homeless. The rate of burn injury requiring hospitalization for homeless adults was estimated at 88 per 100,000 persons. Homeless patients had a significantly larger median burn size (7 vs 5%, P < .05) and a greater rate of flame burns (68 vs 42%, P < .001). For the homeless, rates of assault and self-inflicted injury were 4- (18 vs 4%, P < .001) and 2-fold higher (9 vs 4%, P < .001), respectively. Homeless patients had higher rates of mental illness (32 vs 12%, P < .001) and substance abuse (88 vs 22%, P < .001), and were less likely to follow-up as outpatients (54 vs 87%, P < .001). There was no difference in mortality. Homeless patients had a longer median length of stay (LOS; 11 vs 7 days, P < .001) without significant differences in LOS per percentage TBSA. Homeless individuals should be considered a high-risk population for burn injury. This distinction serves as a call to action for the development of burn prevention strategies.

Abstract
Burns continue to be a common cause of morbidity around the world, and socioeconomic status has been linked to high-burn risk in developed and developing countries. The purpose of this study was to define in Winnipeg, Manitoba, Canada: 1) demographics of adult patients with severe burns; 2) the relationship between household income and burn incidence; and 3) specific geographic areas that may benefit from targeted burn prevention strategies. We conducted a retrospective study of adult (>18 years) patients in Winnipeg, with burns severe enough to require at least 1 day of hospitalization between 2006 and 2016. Area-level median household income data at two geographic levels were collected from 2011 Census based on patient postal codes. Of 207 patients that met study criteria, 156 (75.4%) were male. Mean age was 44.5 ± 16.9 years, and the most common cause of burns was fire/flame (52.2%). The analysis of income data revealed that lower area-level income groups had a higher incidence of burns, with the lowest income quintile group having 5.4 times higher incidence than highest income quintile group. Spatial analysis software was used to map the incidence rates, and clusters of high-risk burns were identified in and around the city center region. Overall, our study showed an inverse relationship between area-level income and burn injury incidence. The identification and mapping of high incidence hotspots will allow policy makers to target groups who will benefit most from burn prevention strategies.

Assessment of the Risk of Oral Cancer Incidence in A High-Risk Population and Establishment of A Predictive Model for Oral Cancer Incidence Using A Population-Based Cohort in Taiwan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E665.

Abstract
We aimed to assess the risk of oral cancer incidence in a high-risk population, establish a predictive model for oral cancer among these high-risk individuals, and assess the predictive ability of the constructed model. Individuals aged ≥30 years who had a habit of smoking or betel nut chewing and had undergone oral cancer screening in 2010 or 2011 were selected as study subjects. The incidence of oral cancer among the subjects at the end of 2014 was determined. The annual oral cancer incidence among individuals with a positive screening result was 624 per 100,000 persons, which was 6.5 times that of the annual oral cancer incidence among all individuals screened. Male sex, aged 45-64 years, divorce, low educational level, presence of diabetes, presence of other cancers, high comorbidity severity, a habit of smoking or betel nut chewing, and low monthly salary were high-risk factors for oral cancer incidence (p < 0.05). The area under the curve of the predictive model for oral cancer incidence was 0.73, which indicated a good predictive ability. Therefore, the oral cancer screening policy for the high-risk population with a habit of smoking and/or betel nut chewing is beneficial for the early diagnosis of oral cancer.

Abstract
Census tracts are often used to investigate area-based correlates of a variety of health outcomes. This approach has been shown to be valuable in understanding the ways that health is shaped by place and to design appropriate interventions that account for community-level processes. Following this line of inquiry, it is common in the study of pedestrian injuries to aggregate the point level locations of these injuries to the census tracts in which they occur. Such aggregation enables investigation of the relationships between a range of socioeconomic variables and areas of notably high or low incidence. This study reports on the spatial distribution of child pedestrian injuries in a mid-sized U.S. city over a three-year period. Utilizing a combination of geospatial approaches, Near Analysis, Kernel Density Estimation, and Local Moran’s I, enables identification, visualization, and quantification of close proximity between incidents and tract boundaries. Specifically, results reveal that nearly half of the 100 incidents occur within roads that are also census tract boundaries. Results also uncover incidents that occur on tract boundaries, not merely near them. This geographic pattern raises the question of the utility of associating area-based census data from any one tract to the injuries occurring in these border zones. Furthermore, using a standard spatial join technique in a Geographic Information System (GIS), these points located on the border are counted as falling into census tracts on both sides of the boundary, which introduces uncertainty in any subsequent analysis. Therefore, two additional approaches of aggregating points to polygons were tested in this study. Results differ with each approach, but without any alert of such differences to the GIS user. This finding raises a fundamental concern about techniques through which points are aggregated to polygons in any study using point level incidents and their surrounding census tract socioeconomic data to understand health and place. This study concludes with a suggested protocol to test for this source of uncertainty in analysis and an approach that may remove it.

CANADIAN JOURNAL OF PUBLIC HEALTH = REVUE CANADIENNE DE SANTE PUBLIQUE 2016; 107:e424-e430. [PMID: 28026709 PMCID: PMC6972365 DOI: 10.17269/cjph.107.5459] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 08/28/2016] [Accepted: 07/03/2016] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Postal codes are often the only available geographic identifiers in many sources of health data in Canada. In order to conduct geographic analyses, postal codes are routinely geocoded to census geography to link to ecological data. Despite common use of this method, the extent of geographic misclassification errors is poorly understood. We estimated misclassification errors in the geocoding of postal codes to assign census geography in Nova Scotia, Canada. METHODS We examined differences between counts and match rates for postal-code geocoded and actual locations of buildings in Nova Scotia at two census administrative area levels: dissemination areas (DAs) and census subdivisions (CSDs). Actual locations were based on the data collected by the provincial government containing actual latitude/longitude of buildings. Variation in misclassification by rurality, using Statistics Canada's classification, was also assessed. RESULTS Outside two urban areas (Halifax Metro and Sydney) which had <10% differences in counts, many DAs had >30% differences. Match rates showed similar patterns, with the vast majority of non-urban DAs having <40% match rates. Even in major urban areas, 10% of DAs had large misclassification errors. Misclassification errors at the CSD level were still too great to estimate counts or rates without further area aggregation. CONCLUSION Routine use of postal code geocoding should be replaced with geocoding of location information using additional identifiers such as civic addresses or latitude and longitude. If data holders did this in-house before providing data to researchers, the accuracy and capacity of geographic analysis would be enhanced while protecting confidentiality.

[PMID: 27480165 PMCID: PMC4970228 DOI: 10.1186/s12885-016-2579-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2016] [Accepted: 07/18/2016] [Indexed: 01/16/2023] Open
Abstract
Background Many factors contribute to socioeconomic status (SES), yet in most survival studies only income is used as a measure for determining SES. We used a complex, composite, census-based metric for socioeconomic deprivation to better distinguish individuals with lower SES and assess its impact on survival and staging trends of oral cancers. Methods Oropharyngeal (OPC) and oral cavity cancer (OCC) cases were identified from the British Columbia cancer registry between 1981–2009 and placed into affluent and deprived neighborhoods using postal codes linked to VANDIX (a composite SES index based on 7 census variables encompassing income, housing, family structure, education, and employment). Stage and cancer-specific survival rates were examined by sex, SES, and time period. Results Approximately 50 % of OPC and OCC cases of both sexes resided in SES deprived neighborhoods. Numbers of cases have increased in recent years for all but OCC in men. The deprivation gap in survival between affluent and deprived neighborhoods widened in recent years for OPC and OCC in men, while decreasing for OPC and increasing slightly for OCC in women. Greater proportions of OCC cases were diagnosed at later stage disease for both sexes residing in deprived neighborhoods, a trend not seen for OPC. Conclusion SES remains a significant independent determinant of survival for both OPC and OCC when using a composite metric for SES. OPC survival rates among men have improved, albeit at slower rates in deprived communities. OCC screening programs need to be targeted towards SES-deprived neighborhoods where greater proportions of cases were diagnosed at a later stage and survival rates have significantly worsened in both sexes.

Abstract
Background Burn injury results in emotional stress affecting dietary intake and antioxidant micronutrient intake, which is known to have effects on recovery outcomes. The study aimed to assess dietary intake of antioxidant micronutrients and recovery outcomes of burn patients. Methods Questionnaires were administered to 40 burn patients at Komfo Anokye Teaching Hospital (Ghana) from January 1, 2014 to May 30, 2014. The data taken include anthropometric measurements and dietary assessment. Their nutrient intakes were assessed with the Nutrient Analysis Template. The average intakes were compared to the recommended daily allowance. Assessment of recovery was based on records of wound healing assessments and infection rates from the health practitioners. Results A cross-sectional study of 40 patients revealed an average total burn surface area (TBSA) of 31.4 %, where 70.0, 35.0, 75.0, 52.5, 12.5 and 32.5 % patients were deficient in vitamins A, C and E, zinc, copper and selenium, respectively and adequate amounts of vitamin C intake were related with significantly better wound healing progress. Positive wound healing outcomes were observed for patients with adequate vitamins A and E and zinc intake. Less infection presented among patients with adequate amount of vitamins A and C and zinc, but this was not observed for patients with adequate vitamin E, copper and selenium. Conclusions Most burn patients did not meet their dietary requirements for antioxidant micronutrients and this was due to meals not tailored to suit individual requirements. Adequacy of the antioxidants especially vitamin C resulted in positive wound healing outcomes. Hence, there is need for planned well-balanced meals of high vitamin C.

Abstract
Objective. Few Canadian studies have examined the relationship between socioeconomic status (SES) and incidence of burn injury. We seek to evaluate this relationship using median income as a measure of SES in Nova Scotia, Canada.Methods. Nova Scotia residents admitted to the Queen Elizabeth II burn unit in Halifax, Nova Scotia, from 1995 to 2012, were included in the study. SES was estimated by linking the subject’s postal code to median family household income via Canadian population census data at the level of dissemination areas. Four equal income groups ranging from lowest to highest income quartile were compared (average total burn percentage). Likelihood ratio was calculated to evaluate the effect of median family income burn injury in each income quartile.Results. 302 patients were included in the analysis. Average percent total burn surface area was 19%, 15%, 15%, and 14% (p=0.18) per income quartile (Q1: lowest, Q4: highest), respectively. Likelihood ratios for income quartile Q1–Q4 were 1.3 (0.8–1.6), 1.2 (0.6–1.4), and 0.7 (0.6–1.2), respectively.Conclusion. Contrary to findings in other geographic regions of the world, severity or incidence of burn injury in Nova Scotia, Canada, does not change in relation to SES when using family median income as a surrogate.

Abstract
BACKGROUND Oral cancer is an important health issue, with changing incidence in many countries. Oropharyngeal cancer (OPC, in tonsil and oropharygeal areas) is increasing, while oral cavity cancer (OCC, other sites in the mouth) is decreasing. There is the need to identify high risk groups and communities for further study and intervention. The objective of this study was to determine how the incidence of OPC and OCC varied by neighbourhood socioeconomic status (SES) in British Columbia (BC), including the magnitude of any inequalities and temporal trends. METHODS ICDO-3 codes were used to identify OPC and OCC cases in the BC Cancer Registry from 1981-2010. Cases were categorized by postal codes into SES quintiles (q1-q5) using VANDIX, which is a census-based, multivariate weighted index based on neighbourhood average household income, housing tenure, educational attainment, employment and family structure. Age-standardized incidence rates were determined for OPC and OCC by sex and SES quintiles and temporal trends were then examined. RESULTS Incidence rates are increasing in both men and women for OPC, and decreasing in men and increasing in women for OCC. This change is not linear or proportionate between different SES quintiles, for there is a sharp and dramatic increase in incidence according to the deprivation status of the neighbourhood. The highest incidence rates in men for both OPC and OCC were observed in the most deprived SES quintile (q5), at 1.7 times and 2.2 times higher, respectively, than men in the least deprived quintile (q1). For OPC, the age-adjusted incidence rates significantly increased in all SES quintiles with the highest increase observed in the most deprived quintile (q5). Likewise, the highest incidence rates for both OPC and OCC in women were observed in the most deprived SES quintile (q5), at 2.1 times and 1.8 times higher, respectively, than women in the least deprived quintile (q1). CONCLUSION We report on SES disparities in oral cancer, emphasizing the need for community-based interventions that address access to medical care and the distribution of educational and health promotion resources among the most SES deprived communities in British Columbia.

Abstract
While largely preventable, fire and hot water-related injuries are common in the United States. Measures recommended to reduce these injuries are smoke alarms (SAs) and lowered hot water temperatures. This study aims to: (i) describe the prevalence of working SAs and safe water temperatures among low-income, urban communities and (ii) explore the relationship between these behaviors and individuals' knowledge and beliefs about them. In this cross-sectional study, the Health Belief Model was used as a guide for understanding the safety behaviors. A total of 603 households had their SAs and hot tap water temperatures tested and were surveyed about their knowledge and beliefs related to these safety behaviors. We found that 40% of households had working SAs on every level and 57% had safe hot water temperatures. Perceived severity and self-efficacy were significantly associated with SA coverage, whereas perceived susceptibility and beliefs about benefits were significantly associated with safe hot water temperatures. This study demonstrates the need to increase the number of homes with working SAs and safe hot water temperatures. Messages focused on a safe home environment could communicate the ease and harm reduction features of SAs and benefits and risk reduction features of safe hot water temperatures.

Abstract
In Canada, stratification by geographic area or socio-economic status remains relatively rare in national and provincial reporting and surveillance for injury prevention and trauma care. As injuries are known to affect some populations more than others, a more nuanced understanding of injury risk may in turn inform more effective prevention policy. In this study we assessed rates of hospitalization and death from motor vehicle collisions (MVC) in British Columbia (BC) by socio-economic status (SES) and by rural and urban status between 2001 and 2007. Excess risk in injury morbidity and mortality between different SES groups were assessed using a population attributable fraction (PAF). Over a six-year period rural populations in BC experienced a three-fold increase in relative risk of death and an average of 50% increase in relative risk of hospitalization due to injury. When assessed against SES, relative risk of MVC mortality increased from 2.36 (2.05-2.72) to 4.07 (3.35-4.95) in reference to the least deprived areas, with an estimated 40% of all MVC-related mortality attributable to the relative differences across SES classes. Results from this study challenge current provincial and national reporting practises and emphasize the utility of employing the PAF for assessing variations in injury morbidity and mortality.

The Vancouver Area Neighbourhood Deprivation Index (VANDIX): a census-based tool for assessing small-area variations in health status. Canadian Journal of Public Health 2012.

Abstract
OBJECTIVE The Vancouver Area Neighbourhood Deprivation Index (VANDIX) is a census-based measure of socio-economic status (SES). It was designed to serve as an accessible and representative proxy marker of population health status without requiring more extensive health data. This paper describes the structure and previous applications of the VANDIX for measuring relative variations in health outcomes in British Columbia, Canada. METHODS The VANDIX was constructed from a 2005 survey of provincial medical health officers asking them to comment on the best census markers of health status in British Columbia. The VANDIX is based on the weighted summation of seven socio-economic variables from the census, including in order of weighted importance: proportion without high school completion; proportion without university completion; unemployment rate; proportion of lone-parent families; average income; proportion of home owners; and employment ratio. RESULTS The VANDIX has been applied in numerous research and policy settings across the province against several distributions of health status, including self-rated health, injury and access to health care services. In each assessment, the VANDIX has shown that socio-economic inequities parallel health inequities. CONCLUSION SES is one of the most influential factors that shape population patterns of health outcomes. Census-based indicators of SES such as the VANDIX can serve as easily accessible and representative markers of population health status, and have application for policy, research and public health promotion.

Abstract
This study investigated the association between individual and area socioeconomic status (SES) and leading causes of unintentional injury mortality in Canadian adults. Using the 1991-2001 Canadian Census Mortality Follow-up Study cohort (N=2,735,152), Cox proportional hazard regression was used to calculate hazard ratios and 95% confidence intervals for all-cause unintentional injury, motor vehicle collision (MVC), fall, poisoning, suffocation, fire/burn, and drowning deaths. Results indicated that associations with SES differed by cause of injury, and were generally more pronounced for males. Low education was associated with an elevated risk of mortality from all-cause unintentional injury and MVC (males only) and poisoning and drowning (both sexes). Low income was strongly associated with most causes of injury mortality, particularly fire/burn and poisoning. Having no occupation or low occupational status was associated with higher risks of all-cause injury, fall, poisoning and suffocation (both sexes) and MVC deaths among men. Associations with area deprivation were weak, and only areas with high deprivation had elevated risk of all-cause injury, MVC (males only), poisoning and drowning (both sexes). This study reveals the importance of examining SES differentials by cause of death from a multilevel perspective. Future research is needed to clarify the mechanisms underlying these differences to implement equity-oriented approaches for reducing differential exposures, vulnerability or consequences of injury mortality.

Abstract
Background Injuries affect all age groups but have a particular impact on young people. To evaluate the incidence of non-fatal, unintentional, injuries among undergraduates in Wenzhou, China, assess the burden caused by these injuries, and explore the associated risk factors for unintentional injuries among these undergraduates, we conducted a college-based cross-sectional study. Methods Participants were selected by a multi-stage random sampling method, and 2,287 students were asked whether they had had an injury in the last 12 months; the location, cause, and consequences of the event. The questionnaire included demographic and socioeconomic characteristics, lifestyle habits, and the scale of type A behaviour pattern (TABP). Multivariate logistic regression models were used; crude odds ratios (ORs), adjusted ORs and their 95% confidence intervals (CIs) were estimated, with students having no injuries as the reference group. Results The incidence of injuries among undergraduates in Wenzhou was 18.71 injuries per 100 person-years (95%CI: 17.12~20.31 injuries per 100 person-years). Falls were the leading cause of injury, followed by traffic injuries, and animal/insect bites. Male students were more likely to be injured than female students. Risk factors associated with unintentional injuries among undergraduates were: students majoring in non-medicine (adjusted OR: 1.53; 95% CI: 1.19-1.96); type A behaviour pattern (adjusted OR: 2.99; 95% CI: 1.45-6.14); liking sports (adjusted OR: 1.86; 95% CI: 1.41-2.45). Conclusions Injuries have become a public health problem among undergraduates. Falls were the major cause of non-fatal injury. Therefore, individuals, families, schools and governments should promptly adopt preventive measures aimed at preventing and controlling morbidity due to non-fatal injury, especially among students identified to be at high-risk; such as male students with type A behaviour pattern who like sports.

Abstract
BACKGROUND Recent studies have shown that the morbidity and mortality associated with injury of pedestrians are inversely related to socio-economic status (SES). However, in drawing inferences from this association, investigators have paid little attention to the modifiable artifacts related to scale and how the data are partitioned. The purpose of this population-based study was to identify the relation between SES and incidence patterns of pedestrian injury at 4 different geographic scales. METHODS We used a Poisson generalized linear model, stratified by age and sex, to analyze the relation between each of 4 area measures of SES and incidence patterns of pedestrian injuries occurring in metropolitan Vancouver between 1 January 2001 and 31 March 2006. The 4 area measures of SES were based on boundaries of dissemination areas, census tracts, custom-defined census tracts (generated by reassignment of dissemination area boundaries by means of a geographic information system) and census subdivisions of the Canadian census. We measured the SES of the location where the injury occurred with the Vancouver Area Neighbourhood Deprivation Index. RESULTS A total of 262 injuries in adults (18 years of age or older) were analyzed. Among adult men, the odds ratio (OR) for injury of pedestrians at the scale of dissemination area was 4.93 (95% confidence interval [CI] 2.89-8.42) for areas having the lowest SES relative to those with the highest SES. For the same population, the OR for injury was lower with increasing aggregation of data: 2.33 (95% CI 1.45-3.74) when census tracts were used, 3.26 (95% CI 2.06-5.16) when modified census tracts were used and 1.27 (95% CI 0.47-3.45) when census subdivisions were used. Among adult women, the OR for pedestrian injury by SES was highest at the scale of census subdivision within medium-low SES areas (4.33, 95% CI 1.23-15.22). At the census subdivision scale, the relation between SES and incidence pattern of injury was not consistent with findings at smaller geographic scales, and the OR for injury decreased with each increase in SES. INTERPRETATION In this analysis, there was significant variability when different administrative boundaries were applied as proxy measures of the effects of place on incidence patterns of injury. The hypothesized influence of SES on prevalence of pedestrian injury followed a statistically significant socio-economic gradient when analyzed using small-area boundaries of the census. However, researchers should be aware of the inherent variability that remains even among the more homogenous population units.

Abstract
Intentional and unintentional injury is the leading cause of death and potential years of life lost in the first four decades of life in industrialized countries around the world. Despite surgical innovations and improved access to emergency care, research has shown that certain populations remain particularly vulnerable to the risks and consequences of injury. Recent evidence has shown that the analytical, data linkage, and mapping tools of geographic information systems (GIS) technology provide can further address these determinants and identify populations in need. This paper traces the history of injury prevention and discusses current and future challenges in furthering our understanding of the determinants of injury through the use of GIS.
