“…These results corroborate previous studies [37,39] and suggest that, within wards, elderly care workers reporting lower job demands (i.e., quantitative demands and work pace) and higher job resources (i.e., quality of leadership, influence and social support) perceive lower physical exertion. Positive associations of quantitative demands and work pace with perceived physical exertion were expected, as high job demands may lead to direct changes in the amount and intensity of physical work [50], which could increase biomechanical exposure [51,52] and result in higher perceived physical exertion [51]. Our results did not change after adjustment for age, gender, education, BMI, leisure-time physical activity, shift, type of ward, and staffing ratio.…”
