This study aimed to determine the agricultural ergonomic burden in Korean farmers and to analyze its correlation with musculoskeletal pain.
In total, 1001 farmers (525 females and 476 males; mean age, 59.6±7.5years) who owned or rented a farm and belonged to an agricultural cooperative unit were recruited. Ergonomic burdens were assessed using a 20-item Agricultural Work-related Ergonomic Risk Questionnaire (20 agricultural works). The presence of musculoskeletal pain (shoulder, low back, and leg/foot), Farm Stressor Inventory, subjective stress index, and agricultural workload (low, moderate, somewhat hard, or hard) were collected using structured questionnaires.
Factor analysis of the Agricultural Work-related Ergonomic Risk Questionnaire revealed a four-factor solution: neck and upper limb, trunk and push - pull, machine and heavy lifting, and repetitive trauma. Cronbach's alpha was greater than 0.65. For 18 of the 20 items, there was a significant association with the Farm Stressor Inventory, subjective stress index, and agricultural workload. The most frequent ergonomic burdens were squatting (51.2%), highly repetitive wrist movements (53.5%), shoulder flexion at 45-90° (51.2%), and trunk flexion or twisting at≥45° (48.8%). Ergonomic burdens were significantly different in 13 items between sexes. The musculoskeletal pain was associated with increased agricultural burdens in 10 items in male farmers and 14 items in female farmers.
Increased agricultural ergonomic burdens were associated with musculoskeletal pain. Ergonomic burden showed different patterns between male and female farmers, with female farmers appearing to be more affected by ergonomic burden than male farmers.
本研究旨在确定韩国农民的农业人体工程学负担，并分析其与肌肉骨骼疼痛的相关性。
共招募了 1001 名拥有或租用农场并属于农业合作社单位的农民（女性 525 名，男性 476 名；平均年龄 59.6±7.5 岁）。使用 20 项农业工作相关人体工程学风险问卷（20 项农业工作）评估人体工程学负担。使用结构化问卷收集肌肉骨骼疼痛（肩部、腰部和腿部/脚部）、农场应激源清单、主观应激指数和农业工作量（低、中、有些困难或困难）的存在情况。
农业工作相关人体工程学风险问卷的因子分析显示出四个因素解决方案：颈部和上肢、躯干和推拉、机器和重物提升以及重复性创伤。Cronbach's alpha 大于 0.65。对于 20 项中的 18 项，与农场应激源清单、主观应激指数和农业工作量均有显著关联。最常见的人体工程学负担是蹲姿（51.2%）、高度重复手腕运动（53.5%）、45-90°肩部弯曲（51.2%）和≥45°躯干弯曲或扭曲（48.8%）。13 项人体工程学负担在性别之间存在显著差异。10 项男性农民和 14 项女性农民的肌肉骨骼疼痛与农业负担增加相关。
农业人体工程学负担的增加与肌肉骨骼疼痛有关。人体工程学负担在男女农民之间存在不同的模式，女性农民似乎比男性农民更容易受到人体工程学负担的影响。
