OBJECTIVES: To investigate the effects of different sports on the incidence of traumatic fractures (TF; sport-related fractures and those occurring in daily activities) among adolescents during the 9-month follow-up period.METHODS: The adolescents were contacted in 11 different locations (3 public/private schools and 8 sports clubs), and the final sample was divided into 3 groups: control (n=121), swimming (n=51), and impact sports (n=142). The incidence of TF was calculated by considering the exposure to sports (TF/1000h).RESULTS: In the overall sample, the incidence of TF was 1.29TF/1000 hours of sports exposure, while the incidence of sport-related TF was 0.39TF/1000 hours of sports exposure. Adolescents engaged in sports (P=.004), independently of type (P=.001), for 3 or more days per week (P=.004) and more than 60 minutes per day (P=.001) had lower incidence of TF. Adolescents engaged in more than 300 minutes per week of sport (0.17TF/1000h) had lower incidence than those who did not (2.06TF/1000h [P=.001]). A similar finding was observed for sport-related TF (=300min/wk: 0.08TF/1000h vs 300min/wk: 0.615TF/1000h [P=.02]).CONCLUSION: Adolescents engaged in sports showed a lower incidence of TF than nonengaged adolescents.
