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.
这项研究调查了中老年人离家时间与身体活动和久坐行为之间的关系。对 157 名成年人进行了为期 7 天的日记调查，以测量离家时间和工作状态。使用加速度计测量久坐行为和身体活动水平。一年后，原始样本中的 137 人参加了随访调查。从 535 个非工作日和 347 个工作日的日常分析中，多层次模型显示，在非工作日，离家时间越多，与个体内和个体间的久坐时间越少、身体活动水平越高有关。非工作日的纵向分析支持了这些结果。然而，在工作日，日常和纵向分析均未揭示出类似的关联。这些结果表明，增加离家时间可能有助于增加非工作日的身体活动和减少久坐行为。
