 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（由适用提供）：Workactive-P是一项高质量的探索性/发育R21，对创新性的多组分干预措施进行了初步结果评估，旨在提高能量消耗并重新平衡久坐的能量平衡方程的久坐不足的久坐不足，其目标是减少工人的腹部肥胖。多组分干预使用行为变化理论和技术进步，以促进和跟踪步行更多，并在久坐的工作场所使用踏板工作台替代方案。该R21解决了服务行业和国家职业研究议程（NORA）的工作行业的职业久坐行为，特别是腹部对象的健康风险。 Workactive-P是研究练习（R2P）的持续典范，这是我们先前与服务行业的工作，以实施和评估跑步机作为工作站替代方案。在整个2年期间葡萄糖），进行三个武器的3个月对照试验：1）一个组合的电子行为支持计划“ Walk More and Pedal Desk”（WMPD，n = 20），除了在单个工人办公空间中提供专用的踏板桌子外，还支持参与者的日常步行，至少增加3000步/天的步行; 2）通常的工作条件组（con，n = 20）。主要结果是作为MRI确定的内脏脂肪组织（VAT）的腹部肥胖症的变化。次要结局包括体重的变化，总脂肪组织，皮下脂肪组织，血压，血液脂质，空腹葡萄糖和胰岛素，[HBA1C]，自由生活的加速度测定的步行（步骤/天和节奏），花在久坐的行为上，花费在久坐的行为上（花费时间，在久坐不到练习，进行中等效率的体育习惯），并进行饮食中的活动），以及日益度过的。我们将以电子方式跟踪WMPD参与者的每日步骤数据，以及踏板桌的使用时间和节奏（RPM）。在踏板干预措施之上进行逐步计算干预措施可以清楚评估其单独的剂量响应效果。每日通过基于Internet的软件进行踏板桌的使用和步骤/天的步骤/天，可以连续跟踪这两种行为，以量身定制反馈，行为塑造和评估目的。工作型P的预期产出和结果，包括提供明确的可行性和初步有效性证据，用于为服务行业雇主和有兴趣解决与职业久坐行为相关的健康风险暴露（以及相关的医疗保健成本）的实用技术支持的产品和计划的结合。
