Data collection costs in industrial environments for three occupational posture exposure assessment methods

Autor: Trask Catherine, Mathiassen Svend, Wahlström Jens, Heiden Marina, Rezagholi Mahmoud

Publikováno v: BMC Medical Research Methodology, Vol 12, Iss 1, p 89 (2012)

Abstract Background Documentation of posture measurement costs is rare and cost models that do exist are generally naïve. This paper provides a comprehensive cost model for biomechanical exposure assessment in occupational studies, documents the mon

Accuracy and precision of variance components in occupational posture recordings: a simulation study of different data collection strategies

Autor: Liv Per, Mathiassen Svend, Svendsen Susanne

Publikováno v: BMC Medical Research Methodology, Vol 12, Iss 1, p 58 (2012)

Abstract Background Information on exposure variability, expressed as exposure variance components, is of vital use in occupational epidemiology, including informed risk control and efficient study design. While accurate and precise estimates of the

Variation between seated and standing/walking postures among male and female call centre operators

Autor: Toomingas Allan, Forsman Mikael, Mathiassen Svend, Heiden Marina, Nilsson Tohr

Publikováno v: BMC Public Health, Vol 12, Iss 1, p 154 (2012)

Abstract Background The dose and time-pattern of sitting has been suggested in public health research to be an important determinant of risk for developing a number of diseases, including cardiovascular disorders and diabetes. The aim of the present

Bias and imprecision in posture percentile variables estimated from short exposure samples

Autor: Mathiassen Svend Erik, Wahlström Jens, Forsman Mikael

Publikováno v: BMC Medical Research Methodology, Vol 12, Iss 1, p 36 (2012)

Abstract Background Upper arm postures are believed to be an important risk determinant for musculoskeletal disorder development in the neck and shoulders. The 10th and 90th percentiles of the angular elevation distribution have been reported in many

Optimizing cost-efficiency in mean exposure assessment - cost functions reconsidered

Autor: Bolin Kristian, Mathiassen Svend Erik

Publikováno v: BMC Medical Research Methodology, Vol 11, Iss 1, p 76 (2011)

Abstract Background Reliable exposure data is a vital concern in medical epidemiology and intervention studies. The present study addresses the needs of the medical researcher to spend monetary resources devoted to exposure assessment with an optimal
