Sports Injury and Illness Epidemiology: Thailand Team Surveillance During the 30th Southeast Asian Games

Background: Injury and illness surveillance in sports is the first step of the injury prevention model that generates effective injury prevention measures. Objectives: To identify the incidence, severity, and causes of injuries and illness in the Thailand national team during the 30th Southeast Asian (SEA) Games. Methods: All medical encounters were documented using the International Olympic Committee (IOC) injury and illness surveillance system for multi-sport events. We recorded the daily occurrence of injuries and illnesses reported by Thailand’s medical teams over the 12 days of the competition period. Results: Among 980 Thai athletes (568 male and 412 female), that participated in the 30th SEA Games, a total of 105 injuries and illnesses were reported. There were 84 injuries and 21 illnesses which equated to an incidence of 86 injuries and 21 illnesses per 1000 athletes. The most commonly injured body part was the lower leg (14% of all injuries), followed by the shoulder and clavicle. Ligament sprain or rupture and contusion (25% of all injuries) were reported as the most common type of injury. Of all injuries, 56 were classified as needing medical attention (only), 26 caused performance restriction, and two caused complete-time loss. The most common athlete illness was respiratory illness (48% of all illnesses) followed by gastrointestinal illness (19% of all illnesses). One-third (7 out of 21) of athlete illnesses restricted the athlete's performance, and the remaining 14 only required medical attention. Conclusions: Overall, 8% of athletes incurred at least one injury during the competition, and 2% suffered from an illness. Lower leg injury and respiratory illness were the most common, which is similar to other multi-sport events. Based on the research data, injury prevention, especially of ligamentous sprain and lower limb injuries, should be the focus in multi-sport events.
