[Analysis on disease distribution at Beijing 2008 Olympic venues].

Objective: To analyze the incidence and the variety of diseases at Olympic competition venues, non-competition venues and special control zones through the statistical analysis of medical data of Beijing 2008 Olympic Games.
Methods: The proportions of people contracting diseases among different groups, i.e. non-registered people, athletes, staff, media, VIPs and others were analyzed. At different venues the incidence proportions of diseases in cardiovascular system, stomatology, gastroenterology, ENT, respiratory system, surgery, neuropsychiatry, physical injury, genitourinary system and burns were calculated. And the disease spectrum and incidence proportions at specified venues were analyzed.
Results: 1. Among all groups of people involved in Beijing 2008 Olympic Games, the proportion of disease-contracting staff was the highest (44.83%) while that of VIPs the lowest (4.76%) so that the incidence proportions were different among different groups of people. 2. Chi2 = 2427.803, (P < 0.01) The statistical analysis of disease distribution indicates that people at different venues might contract different diseases. 3. The proportions of disease-contracting people at competition venues, non-competition venues, training venues and special control zones were 36.08%, 50.66%, 2.31% and 10.96% respectively, which was related to the number of people at a particular venue. 4. The incidence proportion of surgical diseases was quite high, especially maxillofacial and orthopedic diseases (orthopedic trauma) ranking as top 2 at all venues. Thus there should be surgeons at every venue, especially maxillofacial (for hockey) and orthopedic surgeons. At training venues, the number of people contracting E.N.T. diseases ranked No. 1, chi2 = 74.859 (P < 0.01), compared with that of non-competition venues at No. 2. So the incidence proportion of ENT diseases was higher at training venues than at non-competition venues. The number of people contracting respiratory diseases was the largest in special control zones and the figure of competition venues ranked at No. 2, chi2 = 123.708 (P < 0.01). Therefore the incidence proportion of respiratory diseases at special control zones was higher than that of competition venues.
Conclusion: The proportions of people contracting diseases were different among different groups of people and the staff ranked the first in this regard. People contracted different diseases at different venues so that the distribution of medical resources should cater to this situation. In case of such a large-scale international competition as the Olympic Games, the patients are mainly from competition venues and non-competition venues so these two places have the largest demand for medical staff. The incidence proportion of surgical diseases is quite high and it is important to have maxillofacial and orthopedic surgeons stationed at all the venues. The ophthalmological and ENT specialists are recommended at training venues and respiratory specialists at special control zones. Meanwhile, the gastroenterologic and stomatological specialists should be present at all venues.
