RESUMO
BACKGROUND: Football (soccer) is endorsed as a health-promoting physical activity worldwide. When football programs are introduced as part of general health promotion programs, equal access and limitation of pre-participation disparities with regard to injury risk are important. The aim of this study was to explore if disparity with regard to parents' educational level, player body mass index (BMI), and self-reported health are determinants of football injury in community-based football programs, separately or in interaction with age or gender. METHODOLOGY/PRINCIPAL FINDINGS: Four community football clubs with 1230 youth players agreed to participate in the cross-sectional study during the 2006 season. The study constructs (parents' educational level, player BMI, and self-reported health) were operationalized into questionnaire items. The 1-year prevalence of football injury was defined as the primary outcome measure. Data were collected via a postal survey and analyzed using a series of hierarchical statistical computations investigating associations with the primary outcome measure and interactions between the study variables. The survey was returned by 827 (67.2%) youth players. The 1-year injury prevalence increased with age. For youths with parents with higher formal education, boys reported more injuries and girls reported fewer injuries than expected; for youths with lower educated parents there was a tendency towards the opposite pattern. Youths reporting injuries had higher standardized BMI compared with youths not reporting injuries. Children not reporting full health were slightly overrepresented among those reporting injuries and underrepresented for those reporting no injury. CONCLUSION: Pre-participation disparities in terms of parents' educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. When introduced as a general health promotion, football associations should adjust community-based youth programs to accommodate children and adolescents with increased pre-participation injury risk.

AIMS: The aim of this study was to describe the epidemiology of moderate and severe injury morbidity in a defined population on the basis of ambulance records, and to validate ambulance records as a potential source of surveillance. METHODS: A geographical target area was defined; the county of Värmland, Sweden. All ambulance attendances and hospitalizations for unintentional and intentional injury in 2002 were selected, analysed, and compared. RESULTS: Ambulance data comprised 3,964 injury cases (14.5/1,000). Most injuries for which ambulance attention was sought occurred in road traffic areas (27%), followed by residential areas (20%), school and institutional areas (14%), and sports areas (8%). An ecological comparison between ambulance-based data and hospitalizations showed that ambulance services captured approximately the same amount of injury cases (3,235 ambulance reports, as compared to 3,456 hospital discharges) with a similar profile. CONCLUSIONS: This study provides epidemiological support for ambulance services as a potential source of regular surveillance data on moderate and severe injuries. However, at a population level, our results indicate that ambulance data tend to overestimate some injury categories, and underestimate others, as compared to hospital data. The significance of these differences for preventive work, as well as other practical aspects of the feasibility of regular injury surveillance, will be analysed and discussed on the basis of general criteria for evaluation of surveillance systems in a forthcoming paper.
