Exposure data. Why are they needed?

Aspects of different approaches to study design in the epidemiology of sports injuries are presented, identifying 4 major types: (i) the clinical case series; (ii) the community-based survey; (iii) studies on specific sports or diagnoses without exposure data; and (iv) studies on specific sports or diagnoses with exposure data. The advantages and disadvantages of these concepts are discussed. It is concluded that to optimise preventive efforts and improve the comparability of studies in sports injury epidemiology, there is not only a need for consensus on definitional issues, but also for an agreement on the methodology. Attention to exposure issues is a crucial component of this.

Epidemiology of sports injuries in the Swiss organization "Youth and Sports" 1987-1989. Injuries, exposure and risks of main diagnoses.

In the Swiss organization "Youth and Sports" all acute injuries that are attended to by a physician are registered by the Military Insurance, and data on the number of participants in 32 sports together with the time of exposure are collected by the organization. Per year there are close to 350,000 participants (age 14-20 years) during 13.2 million hours causing more than 5,000 injuries. In a descriptive study the data on the activities in "Youth and Sports" from 1987-1989 have been combined with the injuries which occurred during the same time period. The exposure to risk per 10,000 hours (incidence rate) has been calculated and is presented as a mean of the three years. Icehockey, handball and soccer had the highest incidences in males (8.6, 7.2, and 6.6) followed by wrestling, hiking and basketball (6.3, 3.6, and 3.5). In females the ranking order was handball, soccer and basketball (7.6, 6.7, and 4.9) succeeded by alpine skiing, volleyball and alpinism (3.9, 3.8, and 3.0). A comparison between males and females of the incidence rates in eleven analogous sports showed five significantly higher rates, four in female sports: basketball, alpine skiing, volleyball and apparatus gymnastics, and one in a male sport, hiking. The overall rate was significantly higher in males, but the higher risk was explained by the predominance of male soccer (56% of the injuries in males). After standardization for total exposure the results were even reversed and female sports had a higher overall risk.

On the epidemiology of sports injuries in Switzerland.

A review of the current literature and of insurance data sources on sports injuries in Switzerland during the latest decade is presented. Epidemiological denominator data to determine the population-at-risk and the exposure time are scarce and it is therefore recommended that both the quantity and the quality of Swiss research in this field will be enhanced. It is also proposed that at least one academic institution in Switzerland would assemble systematically all available data of standard format on sports and recreational injuries to ensure a continuous analysis of these data.

Medical treatment and costs of sports-related injuries in a total population.

A prospective study of acute injuries from sports and physical exercise was carried out during 1 year in a total population of a municipality with 31,620 inhabitants. The medical treatment and the services required for the injuries have been calculated and related to the total consumption of medical care in the municipality. A total of 571 injuries (17% of all injuries) occurred in 28 different sports: 65% of the injured were males. Sports injuries accounted for 3% of all acute visits and there were altogether 1,083 outpatient visits, which yields a mean of 1.9 visits per injury. Related to the total consumption of outpatient visits to the five clinics in the municipality sports injuries also accounted for 3%. Forty-four patients were hospitalized; the proportion of inpatient care due to sports injuries was 0.7% and the mean length of stay in hospital 3.9 days. The total amount of sick leave compensated for sports injuries (3,477 days) was 1.2% of all days compensated in 1984. The overall mean cost per injury was US$ 335. Individual sports (motorcycling, downhill skiing and equine sport) were by far the most costly in the Falköping survey, the dearest of the team sports ranking only fifth (handball followed by soccer).

Risk exposure and incidence of injuries in school physical education at different activity levels.

Pupils in the age range of 14-19 years in the schools of a municipality in Sweden were observed prospectively for one year for acute injuries during school physical education (n = 2089). Pupils registered in the Injury Surveillance System for an acute injury sustained during physical education classes and treated by a physician were interviewed. The number of observed injuries was 53. The incidence rate as a ratio of injury and estimated time of activity has been calculated. Physical activity during leisure time was investigated by a mailed questionnaire to a random sample of 7% of the population in the same age range. Levels of physical activity during leisure time of the injured pupils were related to activity levels in the whole population. An increased risk of injury (7 times) was found in pupils with a low activity level, compared to those with a medium or high level, and the risk of injury in females with a sedentary life style was 10 times as high as in active females.

Incidence rate of injuries during sport activity and physical exercise in a rural Swedish municipality: incidence rates in 17 sports.

A prospective study of acute injuries from sports and physical exercise was carried out during 1 year in a total population of a municipality with 31,620 inhabitants. Data on exposure were collected: the number of participants in each sport, the hours of participation, and number of weeks in the season per year. The number of injuries was used as numerator and the exposure data as denominator in a formula modified from Chambers for the calculation of population at risk in sports. A total of 571 injuries occurred in 28 different sports: 65% of the injured were males. The majority of the injuries were from soccer: 50% of the males and 27% of the females. Incidence rates in 17 sports are presented. The ranking order differs, when calculating not only the number, but also the exposure. Ice hockey and handball were then found to have the highest risk followed by soccer. Team and contact sports on the whole had the highest rates in both genders. As a group, intercompany players had the highest rate, especially in soccer. The lowest rates were found in individual sports such as downhill skiing, horseback riding, racket sports, and running. Gymnastics, except in school physical education, had no injuries at all. Sprains and strains were diagnosed in nearly half of the cases and the foot and ankle were the most frequent sites. Preventive measures are proposed.

[Evaluation of a school anti-smoking week].

Week-long anti-smoking campaigns were organised in the schools of an urban area. Telephone interviews were conducted in order to measure the extent to which the community and parents took notice of the campaign and changed their attitude toward smoking. The results show an effect on parents that was dependent on the degree of social integration of the community and the interest in anti-smoking activities prevailing before the campaign.
