目的体力活动是预防和治疗慢性肌肉骨骼疼痛（CMP）的有效干预措施。然而，缺乏研究来告知应该推荐的身体活动强度。本研究的目的是调查用10分钟轻度体力活动（LPA）或中度至剧烈体力活动（MVPA）替代10分钟久坐时间与CMP患病率之间的关系。设计二次分析参与者2313名成年人（>= 16岁）。主要结果测量使用加速度计测量久坐时间，LPA和MVPA。我们使用等时模型来量化CMP的患病率，取代10分钟的久坐时间与10分钟的LPA或MVPA.Results CMP的患病率在这个样本中为17%。LPA和MVPA的未校正患病率分别为0.99（95% CI：0.97 - 1.01）和0.76（0.70 - 0.84）。完全调整后的患病率为1.01（95%CI：0.99至1.02）为LPA和0.89（0.82至0.96）为MVPA.Conclusions替代10分钟的久坐时间与等效期间的LPA与CMP的患病率降低无关，而等效替代MVPA显示出一个小的保护关系。关于CMP患病率，体力活动强度似乎很重要，MVPA而不是LPA显示出保护关系。需要前瞻性研究来调查因果关系。(C)2017物理治疗特许协会。由爱思唯尔有限公司出版。保留所有权利。
Objectives Physical activity is an effective intervention for the prevention and management of chronic musculoskeletal pain (CMP). However, there is a lack of research to inform the intensity of physical activity that should be recommended. The aim of this study was to investigate the association between substituting 10 minutes of sedentary time with either 10 minutes of light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) and the CMP prevalence ratio.Design Secondary Analysis (November 2015) of data from the Health Survey for England (2008).Participants 2313 adults (>= 16 years).Main outcome measures Sedentary time, LPA and MVPA were measured using accelerometry. We used isotemporal models to quantify the prevalence ratio for CMP of replacing 10 minutes of sedentary time with 10 minutes of LPA or MVPA.Results The prevalence of CMP in this sample was 17%. The unadjusted prevalence ratio was 0.99 (95% CI: 0.97 to 1.01) for LPA and 0.76 (0.70 to 0.84) for MVPA. The fully adjusted prevalence ratio was 1.01 (95% CI: 0.99 to 1.02) for LPA and 0.89 (0.82 to 0.96) for MVPA.Conclusions Substituting 10 minutes of sedentary time with an equivalent period of LPA was not associated with a reduction in the prevalence ratio for CMP, whereas the equivalent replacement with MVPA showed a small protective relationship. Regarding CMP prevalence, physical activity intensity appears to be important, with MVPA rather than LPA showing a protective relationship. Prospective studies are needed to investigate causality.
