Studies show conflicting evidence on the association of age and occupational injury in agriculture, and few studies have addressed the effect of age on work-related chronic conditions or preventive practices among farmers.
We examined the probability of injury, work-related stress, musculoskeletal symptoms (MSS), and preventive practices for MSS as a function of aging using surveillance data of 7,711 farm and ranch operators in the central United States.
Segmented regression analyses of men (85% of sample) indicated that the probability of all four outcomes increased up to a certain age and then decreased; the changepoints in years of age being 59.6 for injury, 55.4 for work-related stress, 59.6 for MSS, and 67.9 for MSS preventive practices. Female operators had an increasing trend for stress up to age 29.7, while they showed no changepoints across their age spectrum in the proportion of injury, MSS, and prevention techniques.
CONCLUSION/APPLICATION TO PRACTICE: These findings emphasize the need for preventive efforts particularly among younger and middle-aged farmers and ranchers, and the need to modify work duties to match work abilities at older ages.
关于农业领域年龄与职业伤害之间的关联，研究结果相互矛盾，而且很少有研究探讨年龄对农民工作相关慢性病或预防措施的影响。
我们利用美国中部7711名农场和牧场经营者的监测数据，研究了伤害发生概率、工作相关压力、肌肉骨骼症状（MSS）以及MSS预防措施随年龄变化的情况。
对男性（占样本的85%）进行的分段回归分析表明，所有这四种结果的发生概率在达到一定年龄之前上升，之后下降；受伤概率的年龄转折点为59.6岁，工作相关压力为55.4岁，MSS为59.6岁，MSS预防措施为67.9岁。女性经营者在29.7岁之前压力呈上升趋势，而在受伤、MSS和预防技术比例方面，其各年龄段均无转折点。
结论/实际应用：这些发现强调了预防工作的必要性，尤其是针对年轻和中年农民及牧场主，同时也强调了在老年时调整工作职责以匹配工作能力的必要性。
