Interventions

Two multicomponent interventions of 6 months will be studied. The interventions are both based on ecological frameworks suggesting that behaviour can be influenced on multiple levels including individ

All

Inclusion criteria

Inclusion criteria: 1. Between 18-70 years of age 2. Have the capability of standing and exercising

Exclusion criteria

Exclusion criteria: 1. Not be working for the full duration of the first 6 months of the study (i.e. retirement, maternity leave) 2. Very high physical activity level: more than 30 min/day in prolonged bouts (=10 min) moderate to vigorous physical activity. This exclusion criteria will be checked by assessing physical activity with accelerometers. Note that because we have found that almost all office-workers working at the involved companies have high levels of sedentary behavior, sedentary behavior will not be used as an exclusion criterion

Design outcomes

Primary

MeasureTime frame
Physical activity patterns, including sedentary behaviour, objectively measured with accelerometers (Actigraph) and inclinometers (ActivPAL) at baseline and after the 6-month intervention

Secondary

MeasureTime frame
This 24-month study includes 5 measurement timepoints, with measurements every 6 months Proximal outcomes: 1. Physical activity patterns, including sedentary behaviour, objectively measured with accelerometers (Actigraph) and inclinometers (ActivPAL), at long-term follow-up Distal outcomes (all measured at all specified timepoints): 1. Mental health: including self-reported measures of anxiety and depression (The Hospital Anxiety and Depression Scale, stress (single-item), recovery (self-rating of recovery from work), burnout (Shirom and Melamed burnout measure), general mental health (single-item), life satisfaction (WHO-5 and single-item), and sickness absence 2. Cognition: a comprehensive cognitive test battery assessing the following cognitive domains: processing speed (Digit symbol), attention (Trail Making Test-A), working memory (Capacity: Automated Operation Span; Backward Digit Span), executive functions (Trail Making Test-B, Stroop, n-back), episodic memory (free recall; recognition), semantic memory (SRB:1), and visuospatial ability (Form Board Test). Additionally, self-reported subjective memory complaints (Cognitive Dysfunction Questionnaire) will be assessed. Secondary outcomes (all measured at all specified timepoints, unless otherwise stated): 1. Cardiovascular fitness: participants undergo a submaximal cycle ergometer test. Heart rate response to a submaximal rate of work will be used to estimate maximal oxygen consumption 2. Body composition: body mass index calculated from measured weight and height. Waist circumference (WC) measured in duplicate with participants standing dressed in underwear and exhaled. WC measured at the minimum circumference between the iliac crest and the rib cage 3. Sleep: during night time, participants wear the accelerometer on the non-dominant wrist and additionally self-reported sleep will be assessed (Karolinska Sleep Questionnaire) 4. Self-reported data for physical activity (including active transport) and seden
