Modifying the Workplace to Decrease Sedentary Behaviour and Improve Health.

项目摘要/摘要 持续坐在工作场所会增加包括心脏代谢疾病在内的风险健康问题 死亡率。减少工作场所久坐行为的一种新方法是使用跑步机和 坐立式工作站。这些工作站允许久坐的办公室员工用缓慢的时间取代坐着的时间 行走和/或站立，同时执行工作。然而，关于这一点的经验证据有限 在工作场所使用跑步机和坐立工作台对健康的好处。长期目标是 减少上班族的久坐行为，改善整体健康状况。此应用程序的目标是 确定使用跑步机和坐立工作台减少工作场所久坐行为的效果 超重的办公室工作人员的健康，他们是慢性心血管和代谢性疾病的高危人群。 中心假设是，使用这些工作站减少工作场所的久坐行为将有所改善 研究参与者的整体健康状况。这一假设是基于申请者的初步调查结果 久坐不动的超重上班族使用跑步机工作9个月可改善心血管和 新陈代谢健康。中心假设将通过两个具体目标进行检验：(1)进行为期12个月的 采用意向治疗设计的整群随机试验，以确定使用跑步机和坐着站立的效果 工作场所工作站对超重办公室工作人员(N=66)健康变量的影响 以及(2)比较跑步机和坐立工作台在减少工作场所久坐不动方面的效果 行为。对于目标1，将通过测量重量变化来检查使用这些工作站的效果， 心血管和代谢健康变量(血流动力学、血液生物标记物和身体 构成)、肌肉骨骼不适、心理影响和工作压力。对于目标2，更改所花费的时间 坐、站和走路将使用可穿戴的非侵入性加速度传感器进行测量。这个 方法是创新的，因为这项研究的目的是通过雇主从干预中获得最大收益 支持，测量对久坐行为变化敏感的健康变量，并使用高级 传感器，准确测量久坐行为，并提供实时反馈，以休息 久坐不动。该项目的一个重要成果可能是制定循证战略和 改善办公室环境以减少工作场所久坐行为的建议。一个重要的 工作场所久坐行为减少的结果可能是办公室员工慢性病的减少。 这些潜在的产出和结果符合NIOSH的“R2P：从研究到实践”倡议，该倡议旨在 将NIOSH产生的知识和干预措施转化为预防和消除职业病。这 该项目将通过将工作环境、雇主 和员工，以促进员工的整体健康。此应用程序也与NIOSH的预防相关 通过设计项目组合，旨在用能够预防疾病的设备改造工作环境。 好了！

Project Summary/Abstract Continuous sitting at the workplace increases the risk health problems including cardio-metabolic diseases and mortality. A novel way to reduce workplace sedentary behavior is to modify the workspace using treadmill and sit-to-stand workstations. These workstations allow sedentary office workers to replace sitting time with slow walking and/or standing while simultaneously performing work. However, there is limited empirical evidence on the health benefits of using treadmill and sit-to-stand workstations at the workplace. The long-term goal is to decrease sedentary behavior in office workers and improve overall health. The objective of this application is to determine the effects of decreasing workplace sedentary behavior using treadmill and sit-to-stand workstations on the health of overweight office workers, who are at high risk for chronic cardiovascular and metabolic diseases. The central hypothesis is that decreasing workplace sedentary behavior using these workstations will improve overall health in study participants. This hypothesis is based on preliminary findings from the applicants' where sedentary overweight office workers using treadmill workstations for 9-months improved cardiovascular and metabolic health. The central hypothesis will be tested through two specific aims: (1) To conduct a 12-month, cluster-randomized trial with an intent-to-treat design to determine the effects of using treadmill and sit-to-stand workstations at the workplace on health variables in overweight office workers (N=66) with seated desk jobs and (2) to compare the efficacies of treadmill and sit-to-stand workstations in decreasing workplace sedentary behavior. For aim 1, the effects of using these workstations will be examined by measuring changes in weight, cardiovascular and metabolic health variables (blood flow hemodynamics, blood biomarkers, and body composition), musculoskeletal discomfort, psychological affect and job stress. For aim 2, change in time spent sitting, standing and walking will be measured using wearable non-invasive acceleration sensors. The approach is innovative because the study aims to maximize the gains from the interventions through employer support, measurement of health variables sensitive to change in sedentary behavior and the use of advanced sensors, which accurately measures sedentary behavior and also provides real-time feedback to break prolonged sitting. A significant output of this project may be the development of evidence-based strategies and recommendations that modify the office environment to decrease workplace sedentary behavior. A significant outcome of decreasing workplace sedentary behavior may be a decrease in chronic illness in office workers. These potential outputs and outcomes are in line with NIOSH's 'r2p: Research to Practice' initiative, which aims to translate NIOSH-generated knowledge and interventions to prevent and eliminate occupational illness. This project will address the NORA's Total Worker Health" Initiative by integrating the work environment, employer and employee to promote overall worker health. This application is also pertinent to NIOSH's Prevention Through Design program portfolio aiming to retrofit work environments with equipment that can prevent illness. !
