We investigated the separate and joint effects of multi-site musculoskeletal pain and physical and psychosocial exposures at work on future work ability.
A survey was conducted among employees of a Finnish food industry company in 2005 (n = 1201) and a follow-up survey in 2009 (n = 734). Information on self-assessed work ability (current work ability on a scale from 0 to 10; 7 = poor work ability), multi-site musculoskeletal pain (pain in at least two anatomical areas of four), leisure-time physical activity, body mass index and physical and psychosocial exposures was obtained by questionnaire. The separate and joint effects of multi-site pain and work exposures on work ability at follow-up, among subjects with good work ability at baseline, were assessed by logistic regression, and p-values for the interaction derived.
Compared with subjects with neither multi-site pain nor adverse work exposure, multi-site pain at baseline increased the risk of poor work ability at follow-up, allowing for age, gender, occupational class, body mass index and leisure-time physical activity. The separate effects of the work exposures on work ability were somewhat smaller than those of multi-site pain. Multi-site pain had an interactive effect with work environment and awkward postures, such that no association of multi-site pain with poor work ability was seen when work environment was poor or awkward postures present.
The decline in work ability connected with multi-site pain was not increased by exposure to adverse physical or psychosocial factors at work.
我们研究了多部位肌肉骨骼疼痛以及工作中的身体和心理社会因素对未来工作能力的单独和联合影响。
在 2005 年（n=1201）对芬兰食品行业公司的员工进行了一项调查，2009 年（n=734）进行了随访。通过问卷获得自我评估的工作能力（0 到 10 分的当前工作能力；7=工作能力差）、多部位肌肉骨骼疼痛（至少四个解剖部位中的两个部位疼痛）、休闲时间体力活动、体重指数和身体及心理社会因素。在基线时工作能力良好的受试者中，通过逻辑回归评估多部位疼痛和工作暴露对随访时工作能力的单独和联合影响，并得出交互作用的 p 值。
与既无多部位疼痛也无不良工作暴露的受试者相比，基线时多部位疼痛增加了随访时工作能力差的风险，这与年龄、性别、职业类别、体重指数和休闲时间体力活动有关。工作暴露对工作能力的单独影响略小于多部位疼痛。多部位疼痛与工作环境和不自然姿势之间存在交互作用，当工作环境较差或存在不自然姿势时，多部位疼痛与工作能力差之间没有关联。
多部位疼痛与工作中暴露于不良身体或心理社会因素无关，不会增加工作能力下降的风险。
