Workstation Pilot Study

Not Applicable

Completed

• Conditions: Obesity; Sedentary Lifestyle
• Interventions: Behavioral: WorkStation; Behavioral: Usual Working Condition

• Registration Number: NCT01587092
• Lead Sponsor: Pennington Biomedical Research Center

Brief Summary

This is a pilot study to assess the feasibility of using treadmill desks (Workstations) within a Louisiana office workplace and to determine the effects of walking while working in overweight or obese, sedentary individuals.

Detailed Description

Eligible participants will be randomized by chance to the WorkStation Intervention Group or to a Usual Working Condition Group.

The WorkStation Intervention Group will be asked to walk for up to 1.5 hours per day during the work week of Monday through Friday on the treadmill. Participants will complete two sessions per day for up to 45 minutes per session, tracking time and speed.

Usual Working Condition Group will be asked to continue working in usual environment and accustomed manner.

Regardless of which group the participants are assigned to, the participants will be asked to complete baseline and follow up assessment visits. Months 3 and 6 for approximately 1 hour for Body measurements (height, weight and waist circumference), body fat percent, gait speed, questionnaires, and accelerometry.

Arm && Interventions

Group	Intervention	Description
WorkStation Intervention Group	WorkStation	Participants will be asked to walk for up to 1.5 hours per day on the treadmill. This will be split into two 45 minute sessions per day. Behavioral support will focus on adherence to frequency (attending scheduled sessions). Participants self-select speed of walking and time (they have up to 45 minutes allotted, but may choose less as they like).
Usual Working Condition Group	Usual Working Condition	Participants assigned to the usual working condition control group will continue to work in their usual environment and accustomed manner. The control group participants will have access to the Workstations at the completion of study.

Primary Outcome Measures

Name	Time	Method
Waist	6 months	Waist circumference will decrease in workers assigned to the WorkStation working condition relative to the usual working condition.

Secondary Outcome Measures

Name	Time	Method
Accelerometry	6 months	Participants' activity level measured by the accelerometer will increase in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Weight Assessments	6 months	Weight will improve in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Body Fat Percent	6 months	Body fat percent will improve in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Gait Speed	6 months	Participants' gait speed will improve in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Fatigue	6 months	Participants' fatigue level will decrease in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Stress	6 months	Participants' stress level will decrease in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
Quality of life Questionnaire	6 months	Participants' quality of life will improve in workers assigned to the WorkStation Group relative to the Usual Working Condition Group.
