Sedentary behavior in Dutch workers: differences between occupations and business sectors.
ABSTRACT Sedentary behavior is an independent risk factor for excess body weight and other health problems. There are no published data on sitting time at work, or how this is related to occupation and sector (branch of business). No published study has shown whether extended sitting at work is compensated for by sitting less during leisure time.
This study used data from a continuous cross-sectional survey, from 2000 to 2005 (N=7720). Workers were asked how many minutes they spent sitting during the preceding day, both at work and in their leisure time. To test differences in sitting times among occupational groups and sectors, descriptive analyses and analyses of variance were carried out in 2006.
On average, the Dutch working population reported sitting for 7 hours each day, one third of which was at work. Occupational groups and sectors differed significantly in sedentary behavior, mainly involving sitting periods at work. Workers spending long periods sitting at work did not compensate by sitting less during their leisure time.
Workers spend a substantial part of their waking and working time seated. Those who sat for long periods at work did not compensate for this lack of activity by adopting less-sedentary behaviors during leisure time. To prevent health problems, the best approach may be to reduce sedentary behavior at work, when traveling to and from work, and during leisure time.

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. Implications: Given the high contribution of occupational sitting to total daily sitting time among desk-based employees, interventions should focus on the work setting.Australian and New Zealand Journal of Public Health 12/2014; · 1.64 Impact Factor

ABSTRACT: BACKGROUND:Sitting time is ubiquitous for most adults in developed countries and is most prevalent in three domains: in the workplace, during transport and during leisure time. The correlates of prolonged sitting time in workplace settings are not well understood. Therefore, the aim of this study was to examine the gender-specific associations between the socio-demographic, behavioural and cognitive correlates of work-related sitting time.METHODS:A cross-sectional sample of working German adults (n = 1515; 747 men; 43.5 +/- 11.0 years) completed questionnaires regarding domain-specific sitting times and physical activity (PA) and answered statements concerning beliefs about sitting. To identify gender-specific correlates of work-related sitting time, we used a series of linear regressions.RESULTS:The overall median was 2 hours of work-related sitting time/day. Regression analyses showed for men (beta = -.43) and for women (beta = -.32) that work-related PA was negatively associated with work-related sitting time, but leisure-related PA was not a significant correlate. For women only, transport-related PA (beta = -.07) was a negative correlate of work-related sitting time, suggesting increased sitting times during work with decreased PA in transport. Education and income levels were positively associated, and in women only, age (beta = -.14) had a negative correlation with work-related sitting time. For both genders, TV-related sitting time was negatively associated with work-related sitting time. The only association with cognitive correlates was found in men for the belief 'Sitting for long periods does not matter to me' (beta = .10) expressing a more positive attitude towards sitting with increasing sitting durations.CONCLUSIONS:The present findings show that in particular, higher educated men and women as well as young women are high-risk groups to target for reducing prolonged work-related sitting time. In addition, our findings propose considering increasing transport-related PA, especially in women, as well as promoting recreation-related PA in conjunction with efforts to reduce long work-related sitting times.BMC Public Health 12/2014; 14:1259. · 2.32 Impact Factor
