To describe the distribution, and determine the incidence, of veterinary reported injuries experienced by greyhounds during racing in New Zealand.
This retrospective cohort study utilised data obtained on all greyhound race starts and all racing injuries sustained in New Zealand between 10 September 2014 and 19 June 2019. Greyhound injuries were described by the number and percentage of the type, location, and presumed cause of injuries. The overall incidence of injuries per 1000 racing starts was calculated and stratified incidence rates were calculated for race year, racetrack, race number, sex of the greyhound, country of origin of the greyhound, starting box number, race type, race class and race distance. Poisson regression was used to calculate incidence rate ratios for the outcome of injury and race exposure variables.
There were 213,630 race starts and 4100 injuries. The incidence of injury was 19.2 per 1000 starts, while the number of fatalities at the track was 1.3 per 1000 race starts. Most injuries experienced by greyhounds on race-day were minor (soft-tissue). Most injuries affected the limbs of the greyhounds (82.8%, n = 3393/4100). The rate of injuries was higher in Australian dogs compared with New Zealand dogs, the incidence rate of injury increased with advancing age group and the incidence rate varied among racetracks.
The injury rates were similar to those previously reported for racing greyhounds in New Zealand. This study highlighted the need for greater uniformity and conciseness around the classification of injuries to permit comparisons across jurisdictions.
描述新西兰灰狗比赛中兽医报告的灰狗受伤分布情况，并确定其发病率。
本回顾性队列研究利用了 2014 年 9 月 10 日至 2019 年 6 月 19 日期间在新西兰所有灰狗比赛开始和所有比赛受伤的数据。通过受伤类型、位置和推测原因的数量和百分比来描述灰狗受伤情况。计算了每 1000 次比赛开始的总受伤发生率，并按比赛年份、赛道、比赛次数、灰狗性别、灰狗原籍国、起跑箱号、比赛类型、比赛级别和比赛距离对受伤发生率进行分层。使用泊松回归计算受伤结果和比赛暴露变量的发病率比。
共有 213630 次比赛开始和 4100 次受伤。受伤的发病率为每 1000 次开始 19.2 次，而赛道上的死亡人数为每 1000 次比赛开始 1.3 次。灰狗在比赛日受伤的大多数是轻微的（软组织）。大多数受伤影响灰狗的四肢（82.8%，n=4100/3393）。与新西兰狗相比，澳大利亚狗的受伤率更高，受伤发生率随着年龄组的增加而增加，且不同赛道的受伤发生率也不同。
受伤率与新西兰以前报道的灰狗比赛中相似。本研究强调需要在受伤分类方面更加统一和简洁，以便在司法管辖区之间进行比较。
