Community-level football injury epidemiology: traumatic injuries treated at Swedish emergency medical facilities.

Background: Despite the popularity of the sport, few studies have investigated community-level football injury patterns. This study examines football injuries treated at emergency medical facilities using data from three Swedish counties. Methods: An open-cohort design was used based on residents aged 0-59 years in three Swedish counties (pop. 645 520). Data were collected from emergency medical facilities in the study counties between 1 January 2007 and 31 December 2010. Injury frequencies and proportions for age groups stratified by sex were calculated with 95% confidence intervals (95% CIs) and displayed per diagnostic group and body location. Results: Each year, more than 1/200 person aged 0-59 years sustained at least one injury during football play that required emergency medical care. The highest injury incidence was observed among adolescent boys [2009 injuries per 100 000 population years (95% CI 1914-2108)] and adolescent girls [1413 injuries per 100 000 population years (95% CI 1333-1498)]. For female adolescents and adults, knee joint/ligament injury was the outstanding injury type (20% in ages 13-17 years and 34% in ages 18-29 years). For children aged 7-12 years, more than half of the treated injuries involved the upper extremity; fractures constituted about one-third of these injuries. Conclusions: One of every 200 residents aged 0-59 years in typical Swedish counties each year sustained a traumatic football injury that required treatment in emergency healthcare. Further research on community-level patterns of overuse syndromes sustained by participation in football play is warranted.

Case analyses of all children's drowning deaths occurring in Sweden 1998-2007.

AIMS: The goal of this research project was to explore circumstances surrounding each drowning death occurring to children and adolescents ages 0-17 in Sweden during the years 1998-2007. METHODS: Records from the National Board of Forensic Medicine (NBFM) and other sources were analysed. We collected information on children's personal characteristics (sex, age, ethnic background, weight, height, physical condition, and pre-existing health conditions) and the circumstances of deaths (time and place of occurrence, type of drowning, resuscitation efforts and medical care given, for example). We also collected information on prevention factors: the physical environment, adult supervision, whether or not the child could swim, and if the child was using a personal flotation device at the time of death. RESULTS: Our analysis showed that 109 children had drowned in Sweden during the study period - of this group, 96 had died from unintentional causes. Children from immigrant backgrounds, particularly with families coming from the Middle East and Iran, were inordinately represented in the group of victims who had died from unintentional drowning deaths. Other risk factors included: coming from a single parent-headed family, alcohol use by older victims and a lack of ability to swim. CONCLUSIONS: Prevention efforts to prevent drowning in the future should focus on preventing alcohol use by young bathers; better fencing around swimming sites; improved coverage of swimming lessons to all children in Sweden, especially children from immigrant families; more education on drowning risks for single parents; and better awareness by adults on the need for constant supervision of children and adolescents in and near water.

A comparison of unintentional injury patterns occurring in two Swedish communities in 1978 and in 2008.

Surveillance and analyses of unintentional injuries can be used to help prioritise community prevention efforts. This study describes changes in local patterns for unintentional injuries resulting in deaths, hospitalisations, and outpatient visits to health care clinics and emergency rooms, comparing information from two different study periods, 1978 and 2008, in the Swedish communities of Falköping and Lidköping. Injury cases were analysed, and confidence intervals were derived. The study results show that while most injuries decreased comparing the first study period to the second, these changes were only significant in terms of decreases in outpatient care. This study points to the importance of more systematic collection data of injury events treated at the outpatient level, particularly for communities where there are relatively low numbers of injury-related deaths and hospitalisations.

Socio-economic risk factors for injuries in Swedish children and adolescents: a national study over 15 years.

Few studies have assessed if Sweden's injury prevention work has been equally effective for children of different socio-economic backgrounds. The goal of this paper is to review the country's injury rates for children over time, stratified by socio-economic status (SES), to see if the effects are similar across SES levels. This study employs a retrospective case-control study design, using data from the hospitalisation records of 51,225 children, which were linked to family socio-economic data. Children and adolescents in families receiving social welfare benefits, and those living with single parents and mothers with less education had higher risks of injuries leading to hospitalisation. The population-based safety work over the past decades seems to have had only minor effects on reducing the impact of socio-economic based difference in injury risks to younger Swedes.

Is Sweden still a role model for safety? An overview of unintentional injury data over the past two decades.

This study investigates injury-related mortality and hospitalisations, during 1987-2007 in Sweden. Injuries were classified according to International Classification of Diseases (ICD)--8 for pre-1987 injuries, ICD-9 for 1987-1996 injuries and ICD-10 for injuries occurring in 1997 and later. Data on mortality from injuries during 1987-2007 were collected from Sweden's national Cause-of-Death Register, while data concerning injury diagnoses leading to hospitalisation stays of at least 24 h, occurring during 1987-2007, were obtained from the national Patient Register. Crude rates were derived for injury-related deaths and injury-related hospitalisations for age-gender groups, using population data from Statistics Sweden. Our results showed a mixed picture of injury-related hospitalisations and deaths over the study period. Absolute numbers of injury-related deaths and injury-related hospitalisations decreased over time for the population as a whole and for many, but not all, age-gender groups. When assessing crude injury-related death rates and crude injury-related hospitalisation rates over time, as categorised by gender and age groupings, we also found unchanging or increased risks for injury-related deaths and/or hospitalisations for several age-gender groups. While Sweden has made remarkable progress in reducing injury-related deaths and hospitalisations, there are clear differences in risk that remain.
