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

 描述(由申请人提供)：WorkACTIVE-P是一种高质量的探索性/发展性R21初步结果评估，旨在提高能量消耗并重新平衡久坐工作场所被破坏的能量平衡方程，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来促进和跟踪更多的步行，并在久坐的工作场所使用脚踏式办公桌工作站替代方案。该R21解决了与职业久坐行为相关的健康风险，特别是腹型肥胖，在服务业部门和国家职业研究议程(NORA)的总体工人健康跨部门。WorkACTIVE-P是研究到实践(R2P)的持续示范性工作，建立在我们之前与服务业合作实施和评估跑步机办公桌作为工作站替代方案的基础上。在两年的时间里，我们将与我们的服务行业合作伙伴密切合作，以确定、招募和随机分配40个低活动(&lt；7,500步/天)，超重/肥胖的全职工作人员，40-年龄，腹型肥胖定义为腰围和至少一个额外的代谢综合征组成部分(血脂异常，血压升高，和/或空腹血糖受损)，为期3个月的双臂对照试验：1)综合电子行为支持计划“多走和踏板办公桌”(WMPD，n=20)，除了在个人办公空间提供专用踏板桌子外，参与者还被支持每天增加至少3000步步行；2)常规工作条件组(CON，n=20)。主要的结果是腹部肥胖手术后的变化，表现为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]、自由生活加速计决定的步行(每天的步数和节奏)、久坐行为的时间、锻炼(中等到剧烈体力活动的时间)和饮食摄入量的变化。我们将以电子方式跟踪WMPD参与者的日常步数数据，以及踏板办公桌的使用时间和节奏(Rpm)。在踏板工作台干预的基础上分层进行计步干预，可以清楚地评估其单独和组合的剂量-反应效果。通过基于自动互联网的软件对踏板办公桌的使用和每天的步数进行日常电子跟踪，可以连续跟踪这两种行为，以实现量身定制的反馈、行为塑造和评估目的。WorkACTIVE-P的预期产出和成果包括为服务业雇主和有意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的产品和计划的组合提供明确的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.
