The objective of the study was to determine the incidence of veterinary events that resulted in a horse failing to finish a race and identify risk factors for musculoskeletal injury (MSI) during a race. Data were obtained on Thoroughbred flat race starts in New Zealand between 1 August 2005 and 31 July 2011 (six racing seasons). Stipendiary Steward's reports were key-word searched to identify veterinary events that prevented a horse from finishing a race. Race data were used calculate the incidence of veterinary events per 1000 horse starts and Poisson regression was used to investigate risk factors for MSI. There were 188,616 race starts and 177 reported veterinary events. The incidence of MSI on race day was 0.72 per 1000 starts, whilst the incidence of respiratory events was 0.21 per 1000 starts. The rate of MSI was significantly lower on 'dead' and 'slow' tracks compared with 'good' tracks and significantly greater in longer races (≥1671 m) compared with races of ≤1200 m. The rate of MSI during flat races in New Zealand appears lower than that reported worldwide, which may be due to the management and training of horses in New Zealand or differences in case definitions used in comparable studies.
该研究的目的是确定导致马匹未能完成比赛的兽医事件发生率，并识别比赛期间肌肉骨骼损伤（MSI）的风险因素。获取了2005年8月1日至2011年7月31日（六个赛马赛季）新西兰纯种马平地赛的起始数据。对赛事监察员的报告进行关键词搜索，以识别阻止马匹完成比赛的兽医事件。利用比赛数据计算每1000次马匹起跑的兽医事件发生率，并使用泊松回归分析来研究MSI的风险因素。共有188,616次起跑，报告了177起兽医事件。比赛日MSI的发生率为每1000次起跑0.72例，而呼吸事件的发生率为每1000次起跑0.21例。与“良好”赛道相比，“死”赛道和“慢”赛道上MSI的发生率显著较低；与长度≤1200米的比赛相比，长度≥1671米的较长比赛中MSI的发生率显著更高。新西兰平地赛期间MSI的发生率似乎低于全球报告的发生率，这可能是由于新西兰马匹的管理和训练方式，或可比研究中病例定义的差异所致。
