Between 1992 and 2005, 1412 workers on farms died from tractor overturns. A Rollover Protective Structure (ROPS) is a proven intervention to reduce overturn deaths. However, farm characteristics that are associated with the adoption of ROPS are not well understood.
ROPS prevalence statistics were derived from National Institute for Occupational Safety and Health (NIOSH) surveys that tracked ROPS use on farms. Data were from the years 1993, 2001, and 2004.
In 1993, 38% of tractors were equipped with ROPS. This increased to 51% by 2004. ROPS prevalence rates were higher on farms in the Southern region of the United States, on farms where the operator was 25-34 years old, and on farms with $100,000 or more of farm sales. Low ROPS prevalence rates were associated with farm operators 65 years old or older and with farms with less than $10,000 of farm product sales.
The increase in ROPS prevalence between 1993 and 2004 has not been sufficient to decrease the rate of tractor overturn deaths on farms. Incentive programs targeting older farm operators and low-income farm operations are suggested to increase ROPS use on tractors.
The study provides farm characteristics associated with low ROPS prevalence rates. The results can be used to target farms for future ROPS promotion activities.
1992年至2005年间，有1412名农场工人死于拖拉机翻车事故。翻车保护结构（ROPS）是一种经证实可减少翻车死亡事故的干预措施。然而，与ROPS采用相关的农场特征尚未得到充分了解。
ROPS普及率统计数据源自美国国家职业安全与健康研究所（NIOSH）跟踪农场ROPS使用情况的调查。数据来自1993年、2001年和2004年。
1993年，38%的拖拉机配备了ROPS。到2004年，这一比例增至51%。美国南部地区农场、经营者年龄在25至34岁的农场以及农产品销售额达10万美元或以上的农场，其ROPS普及率较高。ROPS普及率低与65岁及以上的农场经营者以及农产品销售额低于1万美元的农场有关。
1993年至2004年间ROPS普及率的提高不足以降低农场拖拉机翻车死亡率。建议针对老年农场经营者和低收入农场经营实施激励计划，以增加拖拉机上ROPS的使用。
该研究提供了与ROPS普及率低相关的农场特征。研究结果可用于确定未来推广ROPS活动的目标农场。
