Title: Non-exercise Activity Thermogenesis (NEAT) - Prevention and Treatment of Overweight and Obesity
Brief Summary: This study will investigate the effect on Non-exercise Activity Thermogenesis (NEAT) when implementing active workstation at offices compared to conventional office work. The primary hypothesis is that this implementation will lead to a significant increase in time spent walking per day.


Options:
A: Inclusion Criteria:

1. Have chronic low back pain defined as a back pain problem that has persisted at least 3 months and has resulted in pain on at least half the days in the past 6 months
2. Oswestry low back pain index \>20% to ensure a moderate level of disability is present, thus minimizing a potential floor effect
3. Currently perform deskwork at least 20 hours per week at a desk compatible with the sit-stand attachment
4. Stable employment (at least 3 months at current job and plan to stay at current job for the next 6 months)
5. Ability to obtain approval to install sit-stand workstation (i.e., from supervisor)
6. Access to internet connection and email to complete assessment surveys

Exclusion Criteria:

1. Unable to provide informed consent
2. Cardiovascular event in the last 6 months (e.g. heart attack, stoke, heart failure, revascularization procedure)
3. Presence of a comorbid condition that would limit ability to reduce sedentary behavior (e.g. currently undergoing treatment for cancer)
4. Back surgery in the past 3 months or planned in the next year
5. Presence of a medical "red flag" for a serious spinal condition (cancer, compression fracture, signs or symptoms of root compression, infection)
6. Inability to tolerate standing for any reason
7. Currently using a sit-stand desk, standing desk, or wearable activity monitor
8. Currently pregnant or planned pregnancy in the next 6 months
9. Blood pressure \>159/100 mmHg
B: 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
C: Inclusion Criteria:

* full-time member of staff
* access to a work telephone and desktop computer with internet

Exclusion Criteria:

* have a cardiovascular or metabolic disease
* taking any medication
* pregnant
* planned absence \> 1 week during the trial
D: Inclusion Criteria:

* Office workers with mainly sedentary tasks
* BMI 25-40

Exclusion Criteria:

* Severe depression and/or anxiety
* Exhaustion disorder
* Diabetes Mellitus
* Severe cardiovascular disease
* Severe kidney disease
* Musculoskeletal disorders that prohibit walking on a treadmill
* Contraindications for physical activity
* Thyroidea illness
* Pregnancy

For fMRI-study, additional exclusion criteria are:

* Implanted metal- or electrical devices
* Pregnancy
* Extraneous metal pieces in the body
