Regular physical activity (PA) promotes and excessive sedentary behavior (SB) deteriorates health. Yet the Finnish working-aged population spends most of the day sitting. A 1-year Moving To Business (MTB) -intervention supported small and medium-size workplaces to combat sedentariness. This paper reports the changes in employees' PA and SB from before MTB (baseline) to 1 year after baseline (follow-up).
Twelve workplaces with a total of 396 employees participated. Each workplace nominated a team to promote PA and reduce SB at organizational, working unit and employee level. The teams were mentored regionally through meetings, workshop and tools. Changes in PA and SB were assessed with a questionnaire and an accelerometer. Wald Confidence Interval (Cl) for a difference of proportions with matched pairs was used in the questionnaire data (%-points with 95% CI) and linear mixed model in the accelerometer data (minutes and % of wear-time with 95% CI).
The mean age of the respondents to the questionnaire (N = 296; 75%) was 42.6 (SD 10.9), 64% were women, 95% had some education after high school, 74% worked in the day shift, 71% did sedentary work and 51% were overweight. The mean number of actions implemented in the workplaces was 6.8 and the multilevel approach was fully applied in 6 workplaces. Based on the questionnaire the time spent in SB decreased from baseline to follow-up 16% (95% CI -29 to -3) in total and 22% (-41 to -3) at work. The accelerometer showed daily increases of 33.7 min (15.3 to 52.1) and 6.8% (3.1 to 10.4) in total PA, 30.9 min (15.3 to 46.5) and 6.1% (2.9 to 9.2) in light PA and 673 (209 to 1139) more steps at work. Daily SB at work decreased 44.9 min (-68.0 to -21.8) and 7.6% (-11.9 to -3.2). Daily leisure PA declined 11.0 min (-24.9 to 2.9) and 3.2% (-6.2 to -0.2). Number of levels or actions had no effect on changes.
Employees' PA increased and SB reduced at work during the intervention. At the same time leisure PA decreased slightly. Workplaces can achieve meaningful changes in employees' PA and SB if assisted systematically. Controlled studies are needed to confirm the present findings.

规律的体育活动（PA）对健康有益，而久坐行为（SB）过多则会损害健康。然而，芬兰劳动年龄人口一天中的大部分时间都坐着。一项为期一年的“走进企业”（MTB）干预措施支持中小企业应对久坐问题。本文报告了员工从MTB干预前（基线）到基线后1年（随访）期间PA和SB的变化情况。
12个工作场所的396名员工参与其中。每个工作场所指定一个团队，在组织、工作单位和员工层面促进PA并减少SB。通过会议、研讨会和工具对这些团队进行区域指导。使用问卷和加速度计评估PA和SB的变化。问卷数据采用配对比例差异的Wald置信区间（CI）（95%CI的百分点），加速度计数据采用线性混合模型（95%CI的分钟数和佩戴时间百分比）。
问卷受访者的平均年龄（N = 296；75%）为42.6岁（标准差10.9），64%为女性，95%高中毕业后接受过某种教育，74%上日班，71%从事久坐工作，51%超重。工作场所实施的平均行动数量为6.8项，6个工作场所完全采用了多层次方法。根据问卷，SB总时长从基线到随访减少了16%（95%CI -29至-3），工作时减少了22%（-41至-3）。加速度计显示，总PA每日增加33.7分钟（15.3至52.1）和6.8%（3.1至10.4），轻度PA增加30.9分钟（15.3至46.5）和6.1%（2.9至9.2），工作时多走673步（209至1139）。工作时的每日SB减少44.9分钟（-68.0至-21.8）和7.6%（-11.9至-3.2）。每日休闲PA减少11.0分钟（-24.9至2.9）和3.2%（-6.2至-0.2）。层次或行动数量对变化没有影响。
干预期间员工的PA增加，工作时的SB减少。与此同时，休闲PA略有下降。如果得到系统协助，工作场所可以在员工的PA和SB方面实现有意义的变化。需要进行对照研究来证实目前的研究结果。
