The aim of the study was to assess the occurrence and intensity of musculoskeletal pain as a risk factor for reduced work ability.
In total, 1449 workers participated in the study, 64% were younger workers (<45 years old, M 31.4); 36% were ageing workers (≥45 years old, M 50.3), Their health condition was established on the basis of (a) subjective feeling of health on a 5-point scale, (b) pain in 6 parts of the body in the past year; and (c) intensity of pain on a 100-mm visual analogue scale (VAS). Work ability was assessed with the subjective work ability index (WAI).
The results of the study showed that although in the both groups, i.e., younger and ageing workers, the occurrence and intensity of pain in the hands/wrists, neck and lower back were a significant factor which decreased WAI, in ageing workers only the occurrence of pain in the lower back generated higher risk factors for reduced work ability (WAI < 37).
Improving physical and psychosocial working conditions to reduce musculoskeletal complaints, and identifying individuals with such complaints are important in increasing workers' work ability and thus extending their occupational activity.
本研究旨在评估肌肉骨骼疼痛作为工作能力下降风险因素的发生率和强度。
共有1449名工人参与了该研究，其中64%为年轻工人（<45岁，平均31.4岁）；36%为老龄工人（≥45岁，平均50.3岁）。他们的健康状况基于以下方面确定：（a）采用5分制的主观健康感受；（b）过去一年身体6个部位的疼痛情况；（c）采用100毫米视觉模拟量表（VAS）评估的疼痛强度。工作能力通过主观工作能力指数（WAI）进行评估。
研究结果表明，尽管在年轻工人和老龄工人这两组中，手部/腕部、颈部和下背部疼痛的发生率和强度都是降低WAI的重要因素，但在老龄工人中，仅下背部疼痛的发生就产生了更高的工作能力下降风险因素（WAI<37）。
改善身体和心理社会工作条件以减少肌肉骨骼不适，并识别有此类不适的个体，对于提高工人的工作能力从而延长其职业活动时间非常重要。
