TL;DR: In this paper, a systematic review of smartphone-based interventions to promote physical activity (PA) and reduce sedentary behavior (SB) is presented, with a focus on integrated dynamic models, such as behavioral intervention technology, control systems, computational agent model, exploit-explore strategy, behavioral analytic algorithm and dynamic decision network.

TL;DR: Low-back symptoms may impact on the extent to which office workers change their workplace sitting and standing time, and a prudent next step to improve the effectiveness of workplace sitting-reduction initiatives such as Stand Up Victoria may be to assess and address the needs of those with pre-existing low-back discomfort.

TL;DR: It is suggested that less sitting at work may have additional benefits of increasing informal interactions between office workers, and be linked to reduced risk of chronic diseases.

TL;DR: In this paper, the authors examined associations of sedentary behaviour with bone mineral density (bone mineral density; BMD) in older adults using dual-energy X-ray absorptiometry.

TL;DR: Working-age adults with LL fractures had lower levels of physical activity 6 months after fracture than those with UL fractures, and older adults showed less improvement over time, suggesting that they are an important target group for interventions aimed at regaining preinjury activity levels.
