The aim was to describe occupational physical activity (OPA) and examine the role of psychosocial job resources among blue-collar workers. In a sample of 198 workers (57% male; mean age 44.9 (SD 9.9) year) from 7 companies in Denmark, two accelerometers (Actigraph) were placed on the thigh and trunk during 1-5 consecutive days, to determine working time spent standing, walking, on feet and in activity of moderate to vigorous intensity level (MVPA). The level of influence and social support at work were assessed by questionnaire. The exposure to OPA significantly varied by particular job type, especially in male predominant occupations. Overall, psychosocial job resources did not affect the exposure to OPA. These findings suggest that workplace interventions aiming to prevent adverse outcomes of OPA among blue-collars workers ought to focus on task redesign and target work organizational factors related to specific job type.
目的在于描述蓝领工人的职业体力活动（OPA），并探讨心理社会工作资源在其中的作用。在丹麦 7 家公司的 198 名工人（57%为男性；平均年龄 44.9（标准差 9.9）岁）中，使用两个加速度计（Actigraph）在大腿和躯干上连续佩戴 1-5 天，以确定站立、行走、站立和中等到剧烈强度水平（MVPA）的工作时间。通过问卷调查评估工作中的影响程度和社会支持。OPA 的暴露程度因特定工作类型而异，尤其是在男性占主导地位的职业中。总的来说，心理社会工作资源并不影响 OPA 的暴露程度。这些发现表明，旨在预防蓝领工人 OPA 不良后果的工作场所干预措施应侧重于任务重新设计，并针对与特定工作类型相关的工作组织因素。
