Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Our objective in this pilot study is to test the combined effect of a) replacing office workers' sedentary workstations with active workstations (LifeBalance Station) and b) optimizing computer workstation ergonomics on daily occupational sedentary time, cardiometabolic risk factors, musculoskeletal symptom health outcomes and work productivity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Aim: To compare the effects of providing sedentary employees with seated active workstations in combination with an ergonomic intervention and regular motivational emails (experimental group) against the ergonomic intervention and regular emails only (active control group) on occupational sedentary behavior over 16 weeks.

Hypothesis: The addition of a seated active workstation will result in significant reductions in daily occupational sedentary time compared to the active control group.

Secondary Aims: To compare the effects of the experimental group against the active control group on secondary measures of cardiometabolic disease risk factors, musculoskeletal discomfort, cognitive function and work productivity.

Hypothesis 1: The experimental group will result in reduced cardiometabolic disease risk, musculoskeletal discomfort and work limitations compared to the active control group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental Group

This group will receive the seated active workstation intervention, the ergonomic intervention and the email intervention for 16 weeks.

Group Type EXPERIMENTAL

Active Workstation Intervention

Intervention Type BEHAVIORAL

Participants in the experimental group will receive a seated active workstation at their work setting for 16 weeks.

Ergonomic Intervention

Intervention Type BEHAVIORAL

Participants of both arms will receive a face to face ergonomic workstation optimization intervention. This consultation will take 30 minutes to complete and will be performed at the participant's actual work station.

Email Intervention

Intervention Type BEHAVIORAL

Participants of both arms will receive three emails per week for 16 weeks. Messages will be consistent with what they hear in the ergonomic intervention (e.g., encourage taking breaks from sitting at work and adjusting posture to be in line with ergonomic principles).

Intervention Type DEVICE

Active Control

This group will receive the ergonomic intervention and email intervention only for 16 weeks. This group will not receive a seated active workstation.

Group Type ACTIVE_COMPARATOR

Ergonomic Intervention

Intervention Type BEHAVIORAL

Participants of both arms will receive a face to face ergonomic workstation optimization intervention. This consultation will take 30 minutes to complete and will be performed at the participant's actual work station.

Email Intervention

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* We will recruit overweight/obese (body mass index 25.0-40.0 kg/m2) adults (18-65 years) working in full-time (minimum 35 hours/week), sedentary (self-report sitting \>75% work time) occupations at an independent work site.

Exclusion Criteria

* Working in an office that will not meet the space or electrical requirements of the active workstation, acute or chronic illness not under treatment of a provider, orthopedic limitations that prohibit physical activity, current or planned pregnancy, hospitalization from a physical or mental disorder in the past six months and/or taking medication that may impair physical activity
