Sedentary behaviours have been linked to poor health, independent of physical activity levels. The objective of this study was to explore an individualised intervention strategy aimed at reducing sedentary behaviours in older Scottish adults.
This feasibility and pilot study was a pre-experimental (one group pretest-posttest) study design. Participants were enrolled into the study in January-March 2012 and data analysis was completed April-October 2012. The study was based in Glasgow, Scotland. Participants received an individualised consultation targeting sedentary behaviour incorporating feedback from an activPAL activity monitor. Outcome measures were objectively (activPAL) and subjectively measured (Sedentary Behaviour Questionnaire) sedentary time.
Twenty four participants received the intervention. Objectively measured total time spent sitting/lying was reduced by 24 min/day (p=0.042), a reduction of 2.2%. Total time spent in stepping activities, such as walking increased by 13 min/day (p=0.044). Self-report data suggested participants achieved behaviour change by reducing time spent watching television and/or using motorised transport.
Interventions to reduce sedentary behaviours in older people are urgently needed. The results of this feasibility and pilot study suggest a consultation approach may help individuals reduce time spent in sedentary behaviours. A larger, controlled trial is warranted with a diverse sample to increase generalisability.
久坐行为与健康状况不佳有关，且不依赖于身体活动水平。本研究的目的是探索一种针对苏格兰老年人群的个体化干预策略，以减少久坐行为。
本研究是一项预实验（单组前后测试）设计的可行性和初步研究。参与者于 2012 年 1 月至 3 月期间入组，数据分析于 2012 年 4 月至 10 月完成。研究地点位于苏格兰格拉斯哥。参与者接受了一项个体化咨询，针对久坐行为，其中包括来自 activPAL 活动监测器的反馈。主要结局测量指标为客观（activPAL）和主观（久坐行为问卷）测量的久坐时间。
共有 24 名参与者接受了干预。客观测量的总坐姿/卧床时间减少了 24 分钟/天（p=0.042），减少了 2.2%。类似步行的活动（例如散步）时间增加了 13 分钟/天（p=0.044）。自我报告数据表明，参与者通过减少看电视和/或使用机动交通工具的时间来实现行为改变。
迫切需要针对老年人减少久坐行为的干预措施。本可行性和初步研究的结果表明，咨询方法可能有助于个人减少久坐行为的时间。需要有更多的、多样化的参与者样本的更大规模、对照试验来提高普遍性。
