It is unknown whether workplace interventions successfully improving health outcomes can also provide concurrent improvements in presenteeism and absenteeism.
A 1-year cluster randomized controlled trial was conducted on 144 employees at a care unit in Denmark. The intervention consisted of calorie-limited diet, physical exercise, and cognitive behavioral training during working hours 1 hour per week. The reference group was offered presentations about healthy lifestyle. Absenteeism and presenteeism (productivity, workability, and sickness absence) were recorded at baseline and after 3 and 12 months of intervention.
In intention-to-treat analysis, a significant effect of the intervention was found for productivity after 3 months. Nevertheless, after 12 months no significant effects on absenteeism or presenteeism were found.
This study suggests that a worksite intervention, despite successfully reducing overweight, does not induce lasting improvements on absenteeism or presenteeism.
目前尚不清楚能否通过改善工作场所干预措施来同时提高出勤率和工作效率。
在丹麦的一个护理单元中，对 144 名员工进行了为期 1 年的群组随机对照试验。该干预措施包括在工作时间内进行限卡饮食、体育锻炼和认知行为训练，每周 1 小时。对照组则提供有关健康生活方式的介绍。在基线和干预 3 个月和 12 个月后记录旷工和工作效率低下（生产力、工作能力和病假）。
在意向性治疗分析中，干预措施在 3 个月后对生产力有显著影响。然而，12 个月后，旷工或工作效率低下均无显著影响。
本研究表明，尽管工作场所干预措施成功地减轻了超重，但并不能持久地提高旷工或工作效率低下的情况。
