Injuries in team sport tournaments during the 2004 Olympic Games.

BACKGROUND: Several authors have analyzed the incidence of injuries in a given sport, but only a few have examined the exposure-related incidence of injuries in different types of sports using the same methodology. PURPOSE: Analysis of the incidence, circumstances, and characteristics of injuries in different team sports during the 2004 Olympic Games. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: During the 2004 Olympic Games, injuries in 14 team sport tournaments (men's and women's soccer, men's and women's handball, men's and women's basketball, men's and women's field hockey, baseball, softball, men's and women's water polo, and men's and women's volleyball) were analyzed. After each match, the physician of the participating teams or the official medical representative of the sport completed a standardized injury report form. The mean response rate was 93%. RESULTS: A total of 377 injuries were reported from 456 matches, an incidence of 0.8 injuries per match (95% confidence interval, 0.75-0.91) or 54 injuries per 1000 player matches (95% confidence interval, 49-60). Half of all injuries affected the lower extremity; 24% involved the head or neck. The most prevalent diagnoses were head contusion and ankle sprain. On average, 78% of injuries were caused by contact with another player. However, a significantly higher percentage of noncontact (57%) versus contact injuries (37%) was expected to prevent the player from participating in his or her sport. Significantly more injuries in male players (46%) versus female players (35%) were expected to result in absence from match or training. The incidence, diagnosis, and causes of injuries differed substantially between the team sports. CONCLUSION: The risk of injury in different team sports can be compared using standardized methodology. Even if the incidence and characteristics of injuries are not identical in all sports, prevention of injury and promotion of fair play are relevant topics for almost all team sports.

Nutritional supplements and doping.

CONTEXT: The problems of doping in sport and the increasing use of nutritional supplements by athletes are issues that intersect to the degree that a large number of supplements may contain substances that are banned in sport. Many supplements contain substances that are associated with significant health hazards. Athletes consuming such supplement products may jeopardize their sporting status, and their health. OBJECTIVES: To clarify and summarize the current status of dietary supplements in general, and to describe specific problems that can be associated with supplement use so that sport physicians might be better prepared to address these issues with their athlete-patients. DATA SOURCE: An analysis of recent and relevant literature accessed through MEDLINE, and interactions with clinicians, laboratory scientists, colleagues, and athletes. CONCLUSIONS: The dietary supplement industry is completely unregulated in the United States; as a consequence, an abundance of supplement products of dubious value, content, and quality are now available around the world. It is known that many supplement products contain substances that are prohibited in sport-typically stimulants or anabolic steroid precursors. Many supplements contain substances (e.g., ephedrine) that have been associated with significant morbidity and mortality. Sport practitioners have particular responsibilities in addressing this issue. Athletes need to be aware of the problems that can follow supplement use, and sport authorities need to ensure that nutritional education and guidance for athletes is of the highest standard. The need for the appropriate regulation of dietary supplements is emphasized.

Stepped care approach to smoking cessation in patients hospitalized for coronary artery disease.

PURPOSE: Smoking cessation is an important goal for smokers with coronary artery disease (CAD) because it reduces cardiac morbidity and mortality. Effective interventions for cigarette smokers with CAD exist, but they often are considered to be intensive and expensive. Stepped-care interventions have been proposed as a promising way to allocate smoking cessation treatments in a cost-effective manner. Stepped care refers to the practice of initiating treatment with low-intensity intervention and then exposing treatment failures to successively more intense interventions. METHODS: To address the efficacy of this approach, 254 cigarette smokers hospitalized with CAD were provided a brief cessation intervention. The participants then were assigned randomly to either a more intensive stepped-care treatment (counseling and nicotine patch therapy) or no additional treatment. Outcomes were point-prevalent abstinence measured 3 months and 1 year after hospital discharge. RESULTS: Stepped-care treatment increased smoking cessation rates from 42% to 53% during a 3-month follow-up period (P =.05), but showed little effect at the 1-year follow-up assessment, as evidenced by a cessation rate for the minimal intervention group of 36% versus 39% for the stepped-care group (P =.36). CONCLUSIONS: A stepped-care approach to smoking cessation increased short-but not long-term point-prevalent abstinence in patients with CAD. For improvement of long-term effectiveness, refinement of the timing and content of stepped-care interventions needs to occur.

Correlates of physical activity change in patients not attending cardiac rehabilitation.

OBJECTIVE: Limited research has identified theoretical correlates of physical activity (PA) change in patients not receiving cardiac rehabilitation. The purpose of the present study was to determine whether changes in self-efficacy, PA intention, perceived severity and susceptibility, and PA benefits/barriers were associated with changes in PA over a 12-month period in these patients. METHODS: Patients (N = 555) not attending cardiac rehabilitation completed a psychosocial questionnaire in hospital and 6 and 12 months after hospitalization for a cardiac event. RESULTS: Hierarchical regression analyses showed that the increase in PA from baseline to 6 months was significantly related to an increase in self-efficacy and PA intentions and a decrease in the impact of health-related barriers. Furthermore, the decrease in PA from 6 to 12 months was significantly related to a decrease in health-related benefits and PA intentions and an increase in time and health-related barriers. Finally, the increase in PA from baseline to 12 months was significantly related to an increase in health-related benefits and intentions and a decrease in health-related barriers. CONCLUSIONS: Changes in PA levels over a 12-month period were associated with changes in various theoretical variables. Interestingly, the associations among these variables with PA varied as a function of time after hospitalization.

Is stress management training a useful addition to physician advice and nicotine replacement therapy during smoking cessation in women? Results of a randomized trial.

PURPOSE: To determine whether a stress management (SM) program could improve cessation rates when added to usual care (UC) among women attempting to quit smoking. DESIGN: Randomized controlled trial conducted during a 12-month period. SETTING: Smoking cessation clinics located within two tertiary care centers in Ottawa, Ontario. SUBJECTS: A total of 332 women smokers 19 years or older who smoked 10 or more cigarettes per day were recruited via advertisements. INTERVENTION. Either UC (physician advice and nicotine replacement therapy) or UC plus an eight-session group SM training program (coping skills development relevant to smoking-specific and generic stressors). MEASURES: Point prevalence abstinence 2 and 12 months after study intake. A secondary outcome of interest was change in perceived stress during the intervention period. RESULTS: On an intent-to-treat basis, the addition of SM to UC had no incremental effect on 2- or 12-month abstinence rates. Abstinence rates at 2 months were 26.2% vs. 31.7% in the UC and SM groups, respectively (p = .59). At 12 months, the rates were 18.5% vs. 20.7% (p = .86). When quit rates were compared including only participants who demonstrated adequate adherence to the intervention protocol, there was a significant difference between the UC and SM groups at 2 months (34.9% vs. 48.7%; adjusted odds ratio, 1.88; 95% confidence interval, 1.04-3.42; p = .04) but not at 12 months (23.0% vs. 28.2%; adjusted odds ratio, 1.24; 95% confidence interval, .64-2.41; p = .53). There was a significant reduction in perceived stress from preintervention to postintervention; however, this decrease was not moderated by group assignment. CONCLUSION: The addition of SM in our setting neither increased abstinence rates nor reduced perceived stress over and above UC in women motivated to quit smoking. Poor attendance at the SM intervention undermined its effectiveness.
