`WorkACTICE-P; Multi-component workplace energy balance intervention.

 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，旨在提高能量消耗，重新平衡久坐工作场所的能量平衡方程，目标是减少工人的腹部肥胖。多成分干预使用行为改变理论和技术进步，以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品。该R21解决了与职业久坐行为相关的健康风险，特别是腹部肥胖，在服务业部门和国家职业研究议程（诺拉）的整体工人健康跨部门。WorkACTIVE-P是从研究到实践（r2 p）的持续示范性努力，建立在我们之前与服务行业合作的基础上，以实施和评估跑步机办公桌作为工作站替代品。在2年的时间里，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名低活跃（<7，500步/天），超重/肥胖久坐不动的全职工作者，40-64岁，腹部肥胖定义为腰围和至少一个代谢综合征的其他组成部分（血脂异常、血压升高和/或空腹血糖受损），进行为期3个月的两组对照试验：1）“多走路、蹬桌子”的综合电子行为支持计划（WMPD，n=20），除了在个人工作人员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步的步行; 2）正常工况组（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）。次要结局包括体重、总脂肪组织、皮下脂肪组织、血压、血脂、空腹血糖和胰岛素、[HbA 1c]、自由生活加速度计测定的步行（步数/天和步频）、久坐行为时间、运动（中度至剧烈体力活动时间）和饮食摄入的变化。我们将以电子方式跟踪WMPD参与者的每日步数数据，以及踏板办公桌的使用持续时间和节奏（rpm）。将计步干预置于踏板桌干预之上，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办公桌使用和每天步数进行日常电子跟踪，可以持续跟踪这两种行为，以提供定制反馈、行为塑造和评估。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（和相关医疗保健成本）的服务业雇主和工人提供实用技术支持产品和计划组合的明确可行性和初步有效性证据。

 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.
