Obesity, Prediabetes, and Perceived Stress in Municipal Workers.

The primary cause of death for men and women in the United States is heart disease. Obesity and diabetes are major contributors to heart disease, and the risk is worsened in the presence of stress. It is clinically useful to identify predictors of obesity and prediabetes in a working population.

Feedback actigraphy and sleep among long-haul truck drivers.

This pilot intervention study evaluated the effect of feedback actigraphy on sleep and sleep-related variables in a group of long-haul truck drivers. Visual feedback from actigraphs provided cues to the truck drivers, alerting them to their accumulated sleep times. Exposure to the cues was hypothesized to lead truck drivers to modify their behavior and result in improvement in sleep and sleep-related variables.
