Older adults are recommended to reduce their sedentary time to promote healthy ageing. To develop effective interventions identifying when, why, and how older adults are able to change their sitting habits is important. The aim of this mixed-method study was to improve our understanding of reasons for (breaking) sedentary behavior in older adults. Thirty older adults (74.0 [±5.3] years old, 73% women) were asked about their believed reasons for (breaking) sedentary behavior, and about their actual reasons when looking at a personal storyboard with objective records of activPAL monitor data and time-lapse camera pictures showing all their periods of sedentary time in a day. The most often mentioned believed reason for remaining sedentary was television/radio (mentioned by 48.3%), while eating/drinking was most often mentioned as actual reason (96.6%). Only 17.2% believed that food/tea preparation was a reason to break up sitting, while this was an actual reason for 82.8% of the study sample. Results of this study show that there is a discrepancy between believed and actual reasons for (breaking) sedentary behavior. These findings suggest developing interventions utilizing the actual reasons for breaking sedentary behavior to reduce sedentary time in older adults.
建议老年人减少久坐时间以促进健康老龄化。为了制定有效的干预措施，确定老年人何时、为何以及如何能够改变他们的久坐习惯非常重要。这项混合方法研究的目的是增进我们对老年人（打破）久坐行为原因的理解。研究询问了30名老年人（74.0[±5.3]岁，73%为女性）关于他们认为的（打破）久坐行为的原因，以及当他们查看带有activPAL监测器数据客观记录和延时相机照片的个人记事板时，照片展示了他们一天中所有久坐时间段的实际原因。最常被提及的久坐原因是看电视/听广播（48.3%的人提到），而饮食则是最常被提及的实际原因（96.6%）。只有17.2%的人认为准备食物/泡茶是打破久坐的一个原因，而这却是82.8%的研究样本的实际原因。这项研究的结果表明，在（打破）久坐行为的认知原因和实际原因之间存在差异。这些发现表明，应利用打破久坐行为的实际原因来制定干预措施以减少老年人的久坐时间。
