这项研究调查了中老年人外出时间与体力活动和久坐行为的关系。对157名成年人进行了为期7天的日记调查，以测量外出时间和工作状态。使用加速度计测量久坐行为和体力活动的时间。一年后，原始样本中的137人参与了后续调查。从对非工作日和347个工作日的每日分析中，多水平模型显示，在非工作日，更多的外出时间与较少的久坐时间和较高的体力活动水平相关，无论是在人内还是人与人之间。对非工作日的纵向分析支持这些结果。然而，在工作日，通过每日或纵向分析并未发现类似的关联。这些结果表明，增加外出时间可能有助于增加身体活动，减少非工作日的久坐行为。
This study examined the associations of time spent out of home with physical activity and sedentary behavior among middle-aged and older adults. A diary survey was conducted for 7 days with 157 adults to measure out-of-home time and working status. Time spent in sedentary behavior and levels of physical activity were measured using an accelerometer. After a year, 137 individuals from the original sample participated in a follow-up survey. From the daily analyses of 535 non-working days and 347 working days, multilevel models revealed that on non-working days, more out-of-home time was associated with less sedentary time and higher levels of physical activity at both within- and between-person levels. Longitudinal analyses of non-working days supported these results. However, on working days, similar associations were not revealed by daily or longitudinal analyses. These results suggest that increasing out-of-home time could contribute to increased physical activity and reduced sedentary behavior on non-working days.
