 DESCRIPTION (provided by applicant): WorkACTIVE-P is a high quality exploratory/developmental R21 preliminary outcome evaluation of an innovative multi-component intervention designed to raise energy expenditure and re-balance the disrupted energy balance equation of sedentary workplaces with a target of reducing workers' abdominal obesity. The multi-component intervention uses behavior change theory and technological advances to promote and track walking more and using a pedal desk workstation alternative in the sedentary workplace. This R21 addresses health risks associated with occupational sedentary behavior, specifically abdominal obesity, in Services Industry Sector and the Total Worker Health cross-sector of the National Occupational Research Agenda (NORA). WorkACTIVE-P is a continued exemplary effort of Research to Practice (r2p), building on our prior work with the Service Industry to implement and evaluate treadmill desks as workstation alternatives. Over the course of a 2-year period we will work closely with our Services Industry partner to identify, recruit, and randomly assign 40 low active (< 7,500 steps/day), overweight/obese sedentary full-time workers, 40-64 years of age, with abdominal obesity defined by waist circumference and at least one additional component of the metabolic syndrome (dyslipidemia, elevated blood pressure, and/or impaired fasting glucose), to a 3-month-long controlled trial with two arms: 1) a combined electronic behavior support program of "walk more and pedal desk" (WMPD, n=20), which, in addition to provision of a dedicated pedal desk in individual worker's office space, participants are supported to increase daily walking by at least 3000 steps/day; and 2) a usual working condition group (CON, n=20). The primary outcome is change in abdominal obesity operationalized as MRI-determined visceral adipose tissue (VAT). Secondary outcomes include changes in body weight, total adipose tissue, subcutaneous adipose tissue, blood pressure, blood lipids, fasting glucose and insulin, [HbA1c], free-living accelerometer-determined walking (steps/day and cadence), time spent in sedentary behavior, exercise (time spent at moderate-to-vigorous physical activity), and dietary intake. We will electronically track daily steps data for WMPD participants and also duration of use and cadence (rpm) of pedal desks. Layering a step-counting intervention on top of a pedal desk intervention permits a clear evaluation of their separate and combined dose-response effects. Daily electronic tracking of pedal desk use and steps/day via automatic internet-based software enables continuous tracking of both behaviors for tailored feedback, behavioral shaping, and evaluation purposes. The expected outputs and outcomes of WorkACTIVE-P include providing clear feasibility and preliminary effectiveness evidence for a combination of practical technology-supported products and programs for Service Industry employers and workers interested in addressing health risk exposures (and related health care costs) associated with occupational sedentary behavior.

 描述（由申请人提供）：WorkACTIVE-P 是一项高质量的探索性/发展性 R21 初步结果评估，旨在评估创新的多成分干预措施，旨在提高能量消耗并重新平衡久坐工作场所被破坏的能量平衡方程，以减少工人的腹部肥胖为目标。多成分干预利用行为改变理论和技术进步来促进和跟踪更多的步行，并在久坐的工作场所使用踏板办公桌工作站替代方案。该 R21 解决了服务业部门和国家职业研究议程 (NORA) 跨部门工人总体健康中与职业久坐行为相关的健康风险，特别是腹部肥胖。 WorkACTIVE-P 是研究到实践 (r2p) 的持续示范性努力，它建立在我们之前与服务行业合作的基础上，实施和评估跑步机办公桌作为工作站替代品。在 2 年期间，我们将与我们的服务行业合作伙伴密切合作，确定、招募并随机分配 40 名低活动量（< 7,500 步/天）、超重/肥胖、久坐的全职工人，年龄 40-64 岁，患有按腰围定义的腹部肥胖和至少一种代谢综合征的其他成分（血脂异常、血压升高和/或禁食受损） 葡萄糖），进行为期 3 个月的双臂对照试验：1）“多走路和踏板办公桌”组合电子行为支持计划（WMPD，n=20），除了在个人员工的办公空间提供专用踏板办公桌外，还支持参与者每天增加至少 3000 步； 2）通常工作条件组（CON，n=20）。主要结果是腹部肥胖的变化，可操作为 MRI 确定的内脏脂肪组织 (VAT)。次要结果包括体重、总脂肪组织、皮下脂肪组织、血压、血脂、空腹血糖和胰岛素、[HbA1c]、自由生活加速度计确定的步行（步数/天和步频）、久坐行为所花费的时间、运动（中度至剧烈体力活动所花费的时间）和饮食摄入量的变化。我们将以电子方式跟踪 WMPD 参与者的每日步数数据以及踏板桌的使用时间和节奏 (rpm)。在踏板干预之上分层计步干预可以清楚地评估其单独和组合的剂量反应效应。通过基于互联网的自动软件对踏板台的使用和每天的步数进行日常电子跟踪，可以持续跟踪这两种行为，以实现定制反馈、行为塑造和评估目的。 WorkACTIVE-P 的预期产出和成果包括为有兴趣解决与职业久坐行为相关的健康风险暴露（以及相关医疗保健费用）的服务行业雇主和工人提供实用技术支持的产品和计划组合的明确可行性和初步有效性证据。
