OBJECTIVE To systematically review the effectiveness of workplace interventions for reducing sitting. METHODS Studies published up to April 2009 were identified by literature searches in multiple databases. Studies were included if they were interventions to increase energy expenditure (increase physical activity or decrease sitting); were conducted in a workplace setting; and specifically me...

BACKGROUND Prolonged sitting has been negatively associated with a range of non-communicably diseases. However, the role of occupational sitting is less clear, and little is known on the changes of occupational sitting in a working population over time. The present study aimed to determine 1) temporal changes in occupational sitting time between 1990 and 2010 in the Danish workforce; 2) the ass...

BACKGROUND Sitting time and breaks in sitting influence cardio-metabolic health. New monitors (e.g. activPAL™) may be more accurate for measurement of sitting time and breaks in sitting although how to optimize measurement accuracy is not yet clear. One important issue is the minimum sitting/upright period (MSUP) to define a new posture. Using the activPAL™, we investigated the effect of variat...

BACKGROUND Studies suggest a relationship between sitting time and cardiovascular disease mortality. Our aim was to identify socio-demographic, contextual, and clinical (e.g., body composition, diabetes duration) correlates of self-reported sitting time among adults with type 2 diabetes, a clinical population at high risk for cardiovascular disease. We sought to determine if there was an invers...

To test the hypothesis that recovering stroke patients with initially good sitting balance or those who develop good sitting balance during rehabilitation have better Barthel Index-based functional assessment outcomes than recovering stroke patients with poor sitting balance, we prospectively studied 24 of 25 consecutive stroke patients admitted to a tertiary-care hospital rehabilitation unit. ...

OBJECTIVES To investigate the differences between a questionnaire-based and accelerometer-based sitting time, and develop a model for improving the accuracy of questionnaire-based sitting time for predicting accelerometer-based sitting time. METHODS 183 workers in a cross-sectional study reported sitting time per day using a single question during the measurement period, and wore 2 Actigraph ...

BACKGROUND Sedentary behaviour is a known risk factor for a wide range of chronic diseases. This major health risk is likely to increase given the increasingly sedentary nature of work. AIMS To investigate the prevalence of sedentary behaviour in a sample of UK working-aged adults, across a range of employment sectors. METHODS A cross-sectional survey conducted with organizations throughout...

BACKGROUND Low back pain (LBP) is a major problem for office workers. Individuals adopting poor postures during prolonged sitting have a considerably increased risk of experiencing LBP. This study aimed to investigate seat pressure distribution characteristics, i.e., average pressure, peak pressure ratio, frequency of postural shift, and body perceived discomfort (BPD), during 1 hour of sitting...

purpose: to evaluate ophthalmologists’ sitting position during ocular examination and surgery and to evaluate any correlation between musculoskeletal disorders and mean work time.   methods: this cross-sectional study was performed on ophthalmologists in isfahan, iran in different occupational positions including the office, during slitlamp examination and in the operating room. the evaluation ...

BACKGROUND A better understanding of how occupational indicators (e.g. job type, doing shift-work, hours worked, physical demand) influence sitting time will aid in the design of more effective health behaviour interventions. The aim of the study was to examine the associations between several occupational indicators and total, occupational and leisure-time sitting. METHODS Cross-sectional se...
