We conducted a 3year intervention to increase awareness and adoption of eight more profitable nursery crop production practices that reduced certain traumatic and musculoskeletal injury hazards.
We disseminated information to nursery managers across seven states using information channels they were known to rely on (e.g. trade publications, public events, university Extension, other managers). We evaluated rolling, independent, probability samples (n=1200) with mail questionnaires before the intervention and after each of 3 intervention years. We also evaluated samples (n=250) from a comparison group of New Zealand nursery managers.
The intervention was associated with increased awareness of four of the eight practices among US managers after year 3 compared to their baseline: zippers (20 vs. 32%, p<or=0.000), stools (11 vs. 22%, p<or=0.001), pruners (29 vs. 40%, p<or=0.014), and tarps (24 vs. 33%, p<or=0.009). There were no changes in adoption. New Zealand manager awareness was increased for hoes after year 2 compared to their baseline (35 vs. 52%, p<or=0.010).
A modest, regionwide information dissemination intervention was associated with increased awareness, but not adoption.
我们进行了为期 3 年的干预措施，以提高对 8 种更有利可图的苗圃作物生产实践的认识并加以采用，这些实践减少了某些创伤和肌肉骨骼损伤的危害。
我们通过苗圃管理人员已知的信息渠道（例如行业出版物、公共活动、大学推广、其他管理人员）向七个州的苗圃管理人员传播信息。我们在干预之前和 3 年干预期间的每个干预年后，使用邮件问卷对滚动、独立、概率样本（n=1200）进行了评估。我们还评估了来自新西兰苗圃管理人员的比较组的样本（n=250）。
与基线相比，3 年后，干预措施与美国管理人员对八项实践中的四项的认识增加有关：拉链（20%比 32%，p<or=0.000）、凳子（11%比 22%，p<or=0.001）、修枝剪（29%比 40%，p<or=0.014）和防水布（24%比 33%，p<or=0.009）。采用率没有变化。与基线相比，第二年新西兰经理对锄头的认识有所提高（35%比 52%，p<or=0.010）。
适度的、区域范围的信息传播干预措施与认识的提高有关，但与采用无关。
