title: Total and domain-specific sitting time among employees in desk-based work settings in Australia.
abstract: OBJECTIVE
  To describe the total and domain-specific daily sitting time among a sample of Australian office-based employees.
  
  
  METHODS
  In April 2010, paper-based surveys were provided to desk-based employees (n=801) in Victoria, Australia. Total daily and domain-specific (work, leisure-time and transport-related) sitting time (minutes/day) were assessed by validated questionnaires. Differences in sitting time were examined across socio-demographic (age, sex, occupational status) and lifestyle characteristics (physical activity levels, body mass index [BMI]) using multiple linear regression analyses.
  
  
  RESULTS
  The median (95% confidence interval [CI]) of total daily sitting time was 540 (531-557) minutes/day. Insufficiently active adults (median=578 minutes/day, [95%CI: 564-602]), younger adults aged 18-29 years (median=561 minutes/day, [95%CI: 540-577]) reported the highest total daily sitting times. Occupational sitting time accounted for almost 60% of total daily sitting time. In multivariate analyses, total daily sitting time was negatively associated with age (unstandardised regression coefficient [B]=-1.58, p<0.001) and overall physical activity (minutes/week) (B=-0.03, p<0.001) and positively associated with BMI (B=1.53, p=0.038).
  
  
  CONCLUSIONS
  Desk-based employees reported that more than half of their total daily sitting time was accrued in the work setting.
  
  
  CONCLUSIONS
  Given the high contribution of occupational sitting to total daily sitting time among desk-based employees, interventions should focus on the work setting.
