摘要
目的:描述成人上肢或下肢骨折出院后两周的久坐行为和身体活动模式,并确定相关的预测因素。设计:观察性研究。环境:一级创伤中心。参与者:18-69岁,孤立性上肢(UL)或下肢(LL)骨折的成年人。主要观察指标:通过基于三轴加速度计和倾角计的装置(activPAL)(大腿前部)测量坐姿时间和步数;通过三轴加速度计(ActiGraph)(臀部)测量10天的中等强度体力活动(MPA)。结果:83名参与者中,63%为男性,55%为左下颌骨折;平均(SD)年龄41(14)岁。参与者平均(SD)为11.07(1.89)小时/天,中位数(IQR)为1575(618-3445)步/天,MPA只有5.22(1.50-20.78)分钟/天。多变量回归分析显示,与UL骨折患者相比,LL骨折患者调整后的平均坐下时间增加了2.5小时/天(β = 2.5小时,p < 0.001)。手术/受伤后每天,调整后的平均坐位时间减少4分钟/天(β = - 0.06小时,p = 0.048)。与UL骨折相比,LL骨折每天行走的步数减少80% (RGM = 0.20, p < 0.001), MPA减少89% (RGM = 0.11, p < 0.001)。与最年轻的参与者相比,年龄越大MPA减少59-62% (RGM = 0.38-0.41, p = 0.01)。预测变量性别、身体质量指数和损伤前的身体活动与任何结果之间没有关联。结论:出院后两周,参与者大量坐着,身体不活动。损伤位置是影响预后的最重要因素,表明左系骨折患者最需要在临床安全范围内减少坐位时间并逐渐增加活动。
Sedentary behaviour and physical activity patterns in adults with traumatic limb fracture
Objective: To describe patterns of sedentary behaviour and physical activity in adults two weeks post-hospital discharge following an upper or lower limb fracture, and identify associated predictive factors. Design: Observational study. Setting: Level 1 Trauma Centre. Participants: Adults aged 18–69 years with an isolated upper (UL) or lower (LL) limb fracture. Main Outcome Measures: Sitting time and steps measured via a triaxial accelerometer and inclinometer-based device (activPAL) (anterior thigh); and moderate-intensity physical activity (MPA) measured via triaxial accelerometer (ActiGraph) (hip) for ten days. Results: Of 83 participants, 63% were men and 55% had sustained LL fractures; mean (SD) age was 41 (14) years. Participants sat for a mean (SD) of 11.07 (1.89) h/day, took a median (IQR) of 1575 (618–3445) steps/day and had only 5.22 (1.50–20.78) mins/day of MPA. Multivariable regression analyses showed participants with LL fracture, had increased adjusted mean sitting time of 2.5 h/day relative to UL fracture (β = 2.5 hours, p < 0.001). For each day since surgery/injury there was reduced adjusted mean sitting time of 4 mins/day (β = −0.06 hours, p = 0.048). LL fracture was associated with 80% fewer steps/day (Ratio of Geometric Means (RGM) = 0.20, p < 0.001) and 89% less MPA (RGM = 0.11, p < 0.001) relative to UL fracture. Older age was associated with 59–62% less MPA relative to the youngest participants (RGM = 0.38–0.41, p = 0.01). There was no association between the predictive variables sex, BMI and pre-injury physical activity and any outcome. Conclusions: At two weeks post-hospital discharge, participants were engaged in high amounts of sitting and were physically inactive. Injury location was the strongest predictor of outcome, indicating that patients with LL fracture are most in need of encouragement to reduce sitting time and gradually increase activity, within the bounds of clinical safety.
