背景虽然减少工作场所久坐行为的主要目标已经明确，但只有少数研究探讨了社会生态因素与工作场所久坐行为之间的关系，以进行有效的干预。本研究旨在探讨日本久坐工作者工作场所久坐行为的社会生态因素。方法以日本松山市和江东区的6000名中年人为研究对象，采用横断面邮寄调查的方法进行研究。参与者回答了一份关于社会生态因素的问卷，在日记中记录了他们的工作时间，并在连续7天的清醒时间内佩戴了三轴加速计。使用加速度计测量工作场所久坐行为，并在记录的日记中称为工作时间。分析中包括主要从事坐姿工作和有效加速计数据的全职工人。工作场所久坐变量是每小时久坐休息时间、久坐时间和>= 30分钟的久坐时间。每个久坐变量和社会生态因素之间的关联进行了探讨，进行三个多元线性回归分析调整社会人口和健康相关因素。结果共有227名参与者（133名男性，平均年龄49.9 ± 6.9岁）被纳入分析。在整个样本中，“经常看到同事久坐休息”与更多的久坐休息时间（B [95%置信区间{CI}=1.40 [0.07至2.73]）和更短的>= 30分钟的久坐时间（B [95% CI] = -7.08 [-13.75至-0.40]）显著相关。“我有动机久坐休息”与久坐休息时间较少（B [95% CI] = -1.36 [-2.61 to -0.12]）和久坐时间较长（B [95% CI] = 4.15 [0.29 to 8.00]）有不利的关联。在男性工作者中，“压力太大而不能久坐休息”与久坐休息时间减少显著相关（B [95% CI] = -5.6 [-9.17 to -2.02]）。结论：看到同事久坐休息可能对减少工作场所久坐行为很重要。那些久坐不动的人有动机采取久坐休息。认为需要在工作时久坐休息的男性员工更喜欢久坐。
Background Although the main targets for reducing workplace sedentary behavior have been clarified, only a few studies have examined the association between social-ecological factors and workplace sedentary behavior for effective intervention. The present study aimed to examine the social-ecological factors of workplace sedentary behavior among Japanese sedentary workers. Methods Participants were recruited via a cross-sectional mail survey targeting randomly sampled 6000 middle-aged people dwelling in Matsuyama-city and Koto-ku in Japan. Participants answered a questionnaire on social-ecological factors, recorded their work time in a diary, and wore a triaxial accelerometer during waking time for 7 consecutive days. Workplace sedentary behavior was measured using accelerometer and was referred to as the work time in the recorded diary. Full-time workers who had mainly sitting work and valid accelerometer data were included in the analysis. Workplace sedentary variables were sedentary breaks per sedentary hour, sedentary time, and >= 30 min bouts of sedentary time. The associations between each sedentary variable and social-ecological factors were explored by conducting three multiple linear regression analyses adjusting for sociodemographic and health-related factors. Results A total of 227 participants (133 men, mean age 49.9 +/- 6.9 years) were included in the analysis. In the overall sample, "typically seeing work colleagues take sedentary breaks" was significantly associated with more sedentary breaks (B [95% confidence interval {CI}=1.40 [0.07 to 2.73]) and shorter >= 30-min bouts of sedentary time (B [95% CI] = -7.08 [-13.75 to -0.40]). "I am motivated to take sedentary breaks" had an unfavorable association with less sedentary breaks (B [95% CI] = -1.36 [-2.61 to -0.12]) and longer sedentary time (B [95% CI] = 4.15 [0.29 to 8.00]). In male workers, "Too stressed to take sedentary breaks" was significantly associated with less sedentary breaks (B [95% CI] = -5.6 [-9.17 to -2.02]). Conclusions Seeing work colleagues take sedentary breaks may be important for reducing workplace sedentary behavior. Those who are more sedentary are motivated to take sedentary breaks. Male workers who feel the need to take sedentary breaks at work are more sedentary.
