Tractor overturns kill an average of 100 farmers and farm workers per year. Roll-over protective structures (ROPS) are a proven intervention, but are not on a sufficient number of tractors in the US to reduce these deaths. Little has been reported on ROPS use by racial minority farm operators.
Data from the NIOSH OISPA survey were used to assess ROPS prevalence rates from a random sample of racial minority farm operators for the year 2003, and ROPS prevalence rates from a random sample of all US farms for the year 2004.
ROPS prevalence rates on minority farming operations follow similar patterns to ROPS prevalence rates on all US farms. A low prevalence of ROPS on farms was associated with operators over the age of 65 years, farms with small acreages, and farms operated on a part-time basis. The race of the operator had little impact on ROPS prevalence rates.
Factors such as acreage, farm operator age, region of the US, and full- or part-time farming status influence ROPS prevalence rates on farms more than the race of the operator. Understanding how ROPS prevalence differs across these farm and farm operator characteristics has the potential to efficiently target areas for ROPS promotion programs across the US.
拖拉机翻车每年平均导致100名农民和农场工人死亡。翻车保护结构（ROPS）是一种经证实的干预措施，但在美国，配备这种装置的拖拉机数量不足以减少此类死亡事故。关于少数族裔农场经营者使用ROPS的情况，此前鲜有报道。
利用美国国家职业安全与健康研究所（NIOSH）职业伤害监测与预防系统（OISPA）调查的数据，评估2003年少数族裔农场经营者随机样本的ROPS普及率，以及2004年美国所有农场随机样本的ROPS普及率。
少数族裔农场作业中ROPS的普及率与美国所有农场ROPS的普及率呈现相似模式。农场中ROPS普及率较低与65岁以上的经营者、小面积农场以及兼职经营的农场有关。经营者的种族对ROPS普及率影响不大。
诸如耕地面积、农场经营者年龄、美国地区以及全职或兼职耕种状况等因素，对农场ROPS普及率的影响大于经营者的种族。了解这些农场和农场经营者特征方面ROPS普及率的差异，有可能有效地确定美国ROPS推广计划的目标区域。
