Is questionnaire-based sitting time inaccurate and can it be improved? A cross-sectional investigation using accelerometer-based sitting time
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 ...
متن کاملAssociations between occupational indicators and total, work-based and leisure-time sitting: a cross-sectional study
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...
متن کاملIs Objectively Measured Sitting Time Associated with Low Back Pain? A Cross-Sectional Investigation in the NOMAD study
BACKGROUND Studies on the association between sitting time and low back pain (LBP) have found contrasting results. This may be due to the lack of objectively measured sitting time or because socioeconomic confounders were not considered in the analysis. OBJECTIVES To investigate the association between objectively measured sitting time (daily total, and occupational and leisure-time periods) ...
متن کاملCorrelates of sitting time in working age Australian women: who should be targeted with interventions to decrease sitting time?
BACKGROUND While there is emerging evidence that sedentary behavior is negatively associated with health risk, research on the correlates of sitting time in adults is scarce. METHODS Self-report data from 7724 women born between 1973-1978 and 8198 women born between 1946-1951 were collected as part of the Australian Longitudinal Study on Women's Health. Linear regression models were computed ...
متن کاملDifferentiating Sitting and Lying Using a Thigh-Worn Accelerometer.
UNLABELLED A triaxial accelerometer worn on the thigh can provide information on the angle of rotation of the thigh. These data may be used to estimate periods of lying versus sitting. PURPOSE To develop and test a classification algorithm to identify sedentary events as either lying or sitting events using a thigh-worn, triaxial accelerometer. METHODS Seven-day free-living activity from 14...
