The aim of this observational cross-sectional study was to determine if allied health professionals working in a large metropolitan health district were meeting the minimal physical activity (PA) recommendations and the proportion that occupational PA contributed to the recommended PA levels. A secondary aim was to determine possible relationships between self-report questionnaire measures of PA and PA measured by accelerometry.
Allied health professionals, working in the Sydney Local Health District (SLHD) in 2016-2017, completed the Active Australia Survey (AAS), Occupational Sitting and Physical Activity Questionnaire (OSPAQ), International Physical Activity Questionnaire Long form (IPAQ-L), and wore the ActiGraph GT1M accelerometer for 7 days consecutively.
Based on accelerometry results, allied health professionals (N=126) spent a mean (SD) of 51 (23) minutes in moderate-to-vigorous physical activity (MVPA)/day, representing 171% of the total recommended MVPA/day, with work contributing 76% to this recommendation. Participants walked a mean of 10,077 (2,766) steps/day, meeting 100% of the recommended 10,000 steps/day, with work contributing 54% to this recommendation. Sedentary behaviors were predominant throughout the entire day and work day. Compared with the ActiGraph MVPA time measurements, AAS MVPA time showed a fair level of agreement [intraclass correlation coefficient (ICC)=0.44, <0.01], while OSPAQ and IPAQ-L MVPA time showed no agreement (ICC=0.05, =0.27; ICC=0.13, =0.10, respectively).
Allied health professionals working in a large metropolitan health district met the daily PA recommendations based on accelerometry measures but tended to overreport their MVPA on self-report questionnaires.
本观察性横断面研究的目的是确定在一个大型都市健康区工作的专职医疗人员是否达到了最低身体活动（PA）建议水平，以及职业性身体活动对建议的身体活动水平的贡献比例。次要目的是确定自我报告问卷测量的身体活动与通过加速度计测量的身体活动之间的可能关系。
2016 - 2017年在悉尼地方健康区（SLHD）工作的专职医疗人员完成了澳大利亚积极生活调查（AAS）、职业久坐与身体活动问卷（OSPAQ）、国际身体活动问卷长表（IPAQ - L），并连续7天佩戴ActiGraph GT1M加速度计。
根据加速度计结果，专职医疗人员（N = 126）每天进行中度至剧烈身体活动（MVPA）的平均（标准差）时间为51（23）分钟，占每日建议MVPA总量的171%，其中工作对该建议量的贡献为76%。参与者平均每天步行10,077（2,766）步，达到了每天建议的10,000步的100%，工作对该建议量的贡献为54%。久坐行为在全天和工作日中占主导。与ActiGraph测量的MVPA时间相比，AAS测量的MVPA时间显示出中等程度的一致性[组内相关系数（ICC）= 0.44，P < 0.01]，而OSPAQ和IPAQ - L测量的MVPA时间则没有一致性（ICC分别为0.05，P = 0.27；ICC = 0.13，P = 0.10）。
在一个大型都市健康区工作的专职医疗人员根据加速度计测量结果达到了每日身体活动建议水平，但在自我报告问卷中往往高估了他们的MVPA。
