Reducing prolonged sitting time in adults

减少久坐——尤其是长时间久坐——的预防信息和指南已经出现。然而，长时间坐着应该用什么来取代，以及在现实世界中改变这种行为的可行性，都是未知的。这个研究项目将提供高质量的证据，证明减少长时间坐着的好处，以及在现实环境中实现减少坐着的有效性和可接受性。

Preventive messages and guidelines to reduce sitting — especially prolonged periods of sitting — have emerged. However, what prolonged sitting should be replaced with, and the feasibility of making real world changes to this behaviour, is unknown. This program of research will provide high quality evidence on the benefits of reducing prolonged sitting time, and the effectiveness and acceptability of achieving sitting reductions in real-world contexts.
