The purpose of this study is to examine associations between objectively measured workplace sedentary behavior and physiological markers of health. We hypothesize that increased sedentary time and more frequent bouts of uninterrupted sitting are associated with increased hemoglobin A1c, increased blood pressure, and impaired endothelial function. Call center employees (N = 241) were enrolled from four worksites in the United States.

Background: In a cluster-randomized trial, the Safety and Health Involvement For Truck drivers intervention produced statistically significant and medically meaningful weight loss at 6 months (-3.31 kg between-group difference). The current manuscript evaluates the relative impact of intervention components on study outcomes among participants in the intervention condition who reported for a postintervention health assessment ( = 134) to encourage the adoption of effective tactics and inform future replications, tailoring, and enhancements.

Although job stress models suggest that changing the work social environment to increase job resources improves psychological health, many intervention studies have weak designs and overlook influences of family caregiving demands. We tested the effects of an organizational intervention designed to increase supervisor social support for work and nonwork roles, and job control in a results-oriented work environment on the stress and psychological distress of health care employees who care for the elderly, while simultaneously considering their own family caregiving responsibilities. Using a group-randomized organizational field trial with an intent-to-treat design, 420 caregivers in 15 intervention extended-care nursing facilities were compared with 511 caregivers in 15 control facilities at 4 measurement times: preintervention and 6, 12, and 18 months.

Objective: To estimate the cost and return on investment (ROI) of an intervention targeting work-family conflict (WFC) in the extended care industry.

Methods: Costs to deliver the intervention during a group-randomized controlled trial were estimated, and data on organizational costs-presenteeism, health care costs, voluntary termination, and sick time-were collected from interviews and administrative data. Generalized linear models were used to estimate the intervention's impact on organizational costs.

This project extends research on hazardous exposures and injuries among home care workers. Historical data from Oregon home care workers were analyzed to identify the most common lost time injuries and contributing factors, and 7 focus groups were conducted with workers (n = 53) to gather data on demographics, health, and perceptions of occupational hazards. Results indicate that workers are at particular risk for back, knee, and shoulder injuries during client and material moving tasks and that workers' self-reported task exposures and risk perceptions are highly aligned with injury data.
