Efficacy of a Combined Ergonomic Health Promotion Intervention on Employee Health

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.

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
