P>；进行研究的原因：耐力是国际马术联合会(FEI)发展最快的项目，需要调查大量因兽医原因而被淘汰的情况。目的：记录在代表五大洲的9个国家由于跛行或代谢原因而被淘汰的潜在风险因素。方法：从FEI网站收集澳大利亚、法国、意大利、南非、西班牙、阿拉伯联合酋长国(UAE)、英国、乌拉圭和美国的骑行数据。收集了该国所有启动马的数据、班级中的马匹数量、骑行距离、班级(例如年轻骑手班级)和获胜马的平均速度。记录了退休、因跛行、代谢和其他原因而被淘汰的情况。采用单因素和多变量Logistic回归模型分析国家、骑马数量、骑行距离和年轻骑手类别对2个结果(因跛行和代谢原因而被剔除)的影响。结果：分析了91个项目157个类别的数据。阿联酋的参赛作品数量最多(1497个)，其次是法国(1029个)和西班牙(408个)。在4326匹启动的马中，46.0%的人完成了骑行。在所有国家中，跛行是最常见的淘汰原因，其次是代谢原因(分别占所有淘汰的69.2%和23.5%，以及31.8%和10.8%的开始使用马)。8%的马匹通过了兽医考试，被骑手退役。在多变量分析中，跛行被排除的风险与骑马所在的国家有关，而且竞争80个参赛项目的马匹的风险显著增加(OR=1.60)。由于代谢原因而被淘汰的风险也与骑马所在的国家显著相关，多变量分析中有100个条目的骑马竞争的风险显著增加(OR=2.17)。结论和潜在相关性：不同国家的淘汰率不同，跛行是全球最常见的淘汰原因。对回顾数据的分析表明，国家和启动马匹的数量是因跛行而被淘汰和因代谢紊乱而被淘汰的风险因素。需要一项前瞻性研究，以评估环境条件、个体马匹速度和其他变量对特定淘汰原因风险的影响。
P>Reasons for performing study:Endurance is the fastest growing Federation Equestre International (FEI) discipline and the large number of eliminations on veterinary grounds needs to be investigated.Objectives:To document elimination rates and explore potential risk factors for elimination due to lameness or metabolic reasons in 9 countries representing 5 continents.Methods:Data for rides of >= 100 km ('elite endurance rides') in Australia, France, Italy, South Africa, Spain, United Arab Emirates (UAE), UK, Uruguay and USA were collected from the FEI website. Data were collected for all started horses on the country, number of horses in the class, ride distance, class (e.g. young rider class) and the average speed of the winning horse. Retirements, eliminations for lameness, metabolic and other reasons were recorded. Uni- and multivariable logistic regression models were used to assess the effect of country, number of horses in the class, ride distance and young rider class on 2 outcomes (elimination for lameness and metabolic reasons).Results:Data for 157 classes at 91 events were analysed. The UAE had the highest number of entries (1497), followed by France (1029) and Spain (408). Of 4326 started horses, 46.0% finished the ride. Lameness was the most common cause of elimination in all countries followed by metabolic reasons (69.2 and 23.5% of all eliminations, and 31.8 and 10.8% of all started horses, respectively). Eight percent of horses were retired by the rider, having passed the veterinary examination. In multivariable analysis, the risk of elimination for lameness was associated with the country in which the ride was held, and the risk significantly increased (OR = 1.60) for horses competing in rides with >= 80 entries. The risk of elimination for metabolic reasons was also significantly associated with the country in which the ride was held and the risk significantly increased (OR = 2.17) for horses competing in rides with >= 100 entries in the multivariable analysis.Conclusions and potential relevance:Elimination rates vary between countries, with lameness being the most common reason for elimination globally. Analysis of retrospective data showed country and number of started horses to be risk factors for elimination due to lameness and for elimination due to metabolic disorders. A prospective study is needed to assess the effects of environmental conditions, individual horse speed and other variables on the risk of specific causes of elimination.
