BACKGROUND Prolonged sitting time is a health risk. We describe a practice-based study designed to reduce prolonged sitting time and improve selected health factors among workers with sedentary jobs. COMMUNITY CONTEXT We conducted our study during March-May 2011 in Minneapolis, Minnesota, among employees with sedentary jobs. METHODS Project(More)
This report describes the World Health Organization Health and Work Performance Questionnaire (HPQ), a self-report instrument designed to estimate the workplace costs of health problems in terms of reduced job performance, sickness absence, and work-related accidents-injuries. Calibration data are presented on the relationship between individual-level HPQ(More)
OBJECTIVE Although major depression is thought to have substantial negative effects on work performance, the possibility of recall bias limits self-report studies of these effects. The authors used the experience sampling method to address this problem by collecting comparative data on moment-in-time work performance among service workers who were depressed(More)
BACKGROUND Many health behaviors and physiologic indicators can be used to estimate one's likelihood of illness or premature death.

This report provides recommendations on the effectiveness of interventions that use an Assessment of(More)
INTRODUCTION Physical inactivity, overweight, and obesity are associated with increased morbidity and mortality. The objective of this study was to estimate the proportion of total health care charges associated with physical inactivity, overweight, and obesity among U.S. populations aged 40 years and older.

The present study was designed to characterize and assess the reliability of acute mood responses to maximal exercise in women. All subjects (N = 22; age = 45 +/- 2.5 yr; BMI = 24.3 +/- 0.9 kg/m2) participated in two maximal walking tests spaced approximately one month apart. The abbreviated Profile of Mood States (POMS) questionnaire was administered(More)
BACKGROUND The prevalence of overweight is increasing and its consequences will cause a major public health burden in the near future. Cost-effective interventions for weight control among the general population are therefore needed.

Cardiometabolic risk (CMR), also known as metabolic syndrome or insulin resistance syndrome, comprises obesity (particularly central or abdominal obesity), high triglycerides, low HDL, elevated blood pressure, and elevated plasma glucose. Leading to death from diabetes, heart disease, and stroke, the root cause of CMR is inadequate physical activity, a(More)
In 1991, Plsek sought to improve the quality of health care by challenging the readers of Crossing the Quality Chasm to find the few simple rules that might guide the local development of the 21st century health system. We have analyzed our health system's activities in the context of systems science as it seeks to create value (improve population health(More)
CONTEXT Uncontrolled hypertension remains a widely prevalent cardiovascular risk factor in the U.S. team-based care, established by adding new staff or changing the roles of existing staff such as nurses and pharmacists to work with a primary care provider and the patient. Team-based care has the potential to improve the quality of hypertension management.(More)
